A nonspecific term referring to impaired vision. Major subcategories include stimulus deprivation-induced amblyopia and toxic amblyopia. Stimulus deprivation-induced amblyopia is a developmental disorder of the visual cortex. A discrepancy between visual information received by the visual cortex from each eye results in abnormal cortical development. STRABISMUS and REFRACTIVE ERRORS may cause this condition. Toxic amblyopia is a disorder of the OPTIC NERVE which is associated with ALCOHOLISM, tobacco SMOKING, and other toxins and as an adverse effect of the use of some medications.
A condition of an inequality of refractive power of the two eyes.
Misalignment of the visual axes of the eyes. In comitant strabismus the degree of ocular misalignment does not vary with the direction of gaze. In noncomitant strabismus the degree of misalignment varies depending on direction of gaze or which eye is fixating on the target. (Miller, Walsh & Hoyt's Clinical Neuro-Ophthalmology, 4th ed, p641)
Clarity or sharpness of OCULAR VISION or the ability of the eye to see fine details. Visual acuity depends on the functions of RETINA, neuronal transmission, and the interpretative ability of the brain. Normal visual acuity is expressed as 20/20 indicating that one can see at 20 feet what should normally be seen at that distance. Visual acuity can also be influenced by brightness, color, and contrast.
The absence or restriction of the usual external sensory stimuli to which the individual responds.
Application of tests and examinations to identify visual defects or vision disorders occurring in specific populations, as in school children, the elderly, etc. It is differentiated from VISION TESTS, which are given to evaluate/measure individual visual performance not related to a specific population.
A pair of ophthalmic lenses in a frame or mounting which is supported by the nose and ears. The purpose is to aid or improve vision. It does not include goggles or nonprescription sun glasses for which EYE PROTECTIVE DEVICES is available.
Agents that dilate the pupil. They may be either sympathomimetics or parasympatholytics.
The blending of separate images seen by each eye into one composite image.
Deviations from the average or standard indices of refraction of the eye through its dioptric or refractive apparatus.
A series of tests used to assess various functions of the eyes.
A form of ocular misalignment characterized by an excessive convergence of the visual axes, resulting in a "cross-eye" appearance. An example of this condition occurs when paralysis of the lateral rectus muscle causes an abnormal inward deviation of one eye on attempted gaze.
Material, usually gauze or absorbent cotton, used to cover and protect wounds, to seal them from contact with air or bacteria. (From Dorland, 27th ed)
The ability to detect sharp boundaries (stimuli) and to detect slight changes in luminance at regions without distinct contours. Psychophysical measurements of this visual function are used to evaluate visual acuity and to detect eye disease.
The study and treatment of defects in binocular vision resulting from defects in the optic musculature or of faulty visual habits. It involves a technique of eye exercises designed to correct the visual axes of eyes not properly coordinated for binocular vision.
The minimum amount of stimulus energy necessary to elicit a sensory response.
Refraction of LIGHT effected by the media of the EYE.
Perception of three-dimensionality.
Images seen by one eye.
Material used for wrapping or binding any part of the body.
The functional superiority and preferential use of one eye over the other. The term is usually applied to superiority in sighting (VISUAL PERCEPTION) or motor task but not difference in VISUAL ACUITY or dysfunction of one of the eyes. Ocular dominance can be modified by visual input and NEUROTROPHIC FACTORS.
A refractive error in which rays of light entering the eye parallel to the optic axis are brought to a focus behind the retina, as a result of the eyeball being too short from front to back. It is also called farsightedness because the near point is more distant than it is in emmetropia with an equal amplitude of accommodation. (Dorland, 27th ed)
Cognitive disorders characterized by an impaired ability to perceive the nature of objects or concepts through use of the sense organs. These include spatial neglect syndromes, where an individual does not attend to visual, auditory, or sensory stimuli presented from one side of the body.
Unequal curvature of the refractive surfaces of the eye. Thus a point source of light cannot be brought to a point focus on the retina but is spread over a more or less diffuse area. This results from the radius of curvature in one plane being longer or shorter than the radius at right angles to it. (Dorland, 27th ed)
The science dealing with the correlation of the physical characteristics of a stimulus, e.g., frequency or intensity, with the response to the stimulus, in order to assess the psychologic factors involved in the relationship.
An objective determination of the refractive state of the eye (NEARSIGHTEDNESS; FARSIGHTEDNESS; ASTIGMATISM). By using a RETINOSCOPE, the amount of correction and the power of lens needed can be determined.
The positioning and accommodation of eyes that allows the image to be brought into place on the FOVEA CENTRALIS of each eye.
A surgical specialty concerned with the structure and function of the eye and the medical and surgical treatment of its defects and diseases.
Investigative technique commonly used during ELECTROENCEPHALOGRAPHY in which a series of bright light flashes or visual patterns are used to elicit brain activity.
A form of ocular misalignment where the visual axes diverge inappropriately. For example, medial rectus muscle weakness may produce this condition as the affected eye will deviate laterally upon attempted forward gaze. An exotropia occurs due to the relatively unopposed force exerted on the eye by the lateral rectus muscle, which pulls the eye in an outward direction.
The act of knowing or the recognition of a distance by recollective thought, or by means of a sensory process which is under the influence of set and of prior experience.
Procedures and programs that facilitate the development or skill acquisition in infants and young children who have disabilities, who are at risk for developing disabilities, or who are gifted. It includes programs that are designed to prevent handicapping conditions in infants and young children and family-centered programs designed to affect the functioning of infants and children with special needs. (From Journal of Early Intervention, Editorial, 1989, vol. 13, no. 1, p. 3; A Discursive Dictionary of Health Care, prepared for the U.S. House of Representatives Committee on Interstate and Foreign Commerce, 1976)
Action taken to reduce susceptibility or exposure to health problems and to detect and treat disease in early stages.
The art, technique, or business of producing motion pictures for entertainment, propaganda, or instruction.
Characteristics or attributes of the outer boundaries of objects, including molecules.
The coordination of a sensory or ideational (cognitive) process and a motor activity.
A raised flat surface on which a patient is placed during surgical procedures.
A surgical procedure to correct MYOPIA by CORNEAL STROMA subtraction. It involves the use of a microkeratome to make a lamellar dissection of the CORNEA creating a flap with intact CORNEAL EPITHELIUM. After the flap is lifted, the underlying midstroma is reshaped with an EXCIMER LASER and the flap is returned to its original position.

Randomised clinical trial of lensectomy versus lens aspiration and primary capsulotomy for children with bilateral cataract in south India. (1/685)

AIMS: The primary objective was to determine which surgical technique gave the best long term visual outcome for infants and young children with bilateral symmetrical cataract in south India. Secondary objectives were to assess complications and the need for further surgical intervention. METHODS: A randomised controlled clinical trial was undertaken. 65 children under 10 years old with bilateral cataract had one eye treated by lensectomy and the other by aspiration with primary capsulotomy. RESULTS: 56 children (86%) with a mean age at surgery of 53 months were reviewed 3 years after surgery. The overall binocular acuity was 6/18 or better in 57.1% and 6/60 or better in 94.6%. There was no difference in visual acuity between the matched pairs of eyes undergoing aspiration or lensectomy at the third year of follow up (p=0.57). Aspiration eyes were more likely to require a secondary procedure to restore vision than lensectomy eyes (66.1% v 1.8%). CONCLUSION: Aspiration with primary capsulotomy gives an acceptable visual outcome in this part of India providing that there is good follow up to manage capsule opacification. If secondary intervention is not possible owing to poor compliance with follow up, then lensectomy is likely to give better long term visual rehabilitation providing there is good maintenance and technical support for the lensectomy equipment.  (+info)

Natural history of amblyopia untreated owing to lack of compliance. (2/685)

AIMS: A prospective study of the efficacy of amblyopia treatment in preschool children has recently been called for, requiring an untreated control group. The present study assessed data from patients with amblyopia untreated owing to lack of compliance, or with amblyopia risk factors, to determine outcome. METHODS: Longitudinal data were obtained from 18 4-6 year old patients who had initially been screened for amblyopia, strabismus, and/or bilateral refractive error, failed to comply with prescribed treatment, and in whom amblyopia was detected at a rescreening approximately a year later. The data from three previous studies comparing outcome of patients compliant and non-compliant with amblyopia treatment were also reanalysed. RESULTS: One child of the 18, who wore glasses sporadically, showed some improvement in visual acuity in the amblyopic eye. Otherwise, no child showed an improvement, and seven of the 17 (41%) for whom visual acuities were available at both screenings showed a deterioration of visual acuity in the amblyopic eye, including three who apparently developed amblyopia for the first time. A child with an ametropic risk factor for amblyopia whose visual acuity was not obtained at the first screening and who was largely non-compliant presented with amblyopia at the second screening. The reanalysed data from the three previous studies demonstrated a significantly poorer visual acuity outcome in the amblyopic eye in the non-compliant patient groups than in the compliant groups in each study. CONCLUSION: Preschool children with amblyopia or its risk factors are at risk of having the current amblyopia deteriorate, or of developing amblyopia, if not treated. These results raise questions about the ethical acceptability of a prospective study of amblyopia treatment at these ages.  (+info)

Preschool vision screening: negative predictive value for amblyopia. (3/685)

BACKGROUND/AIMS: Single optotype tests of visual acuity are widely used for preschool vision screening in order to optimise cooperation with testing. These tests may, however, underestimate the visual acuity deficit in amblyopia because they lack visual crowding. This study assessed the resultant negative predictive value (NPV) for amblyopia. METHODS: Cohort study of 936 children in the Cambridge Health District selected by date of birth. The presence of amblyopia among children who had passed preschool vision screening was determined using Snellen line acuity as the reference test. Preschool vision screening was conducted at 3.5 years of age by community orthoptists. The screening assessment comprised Sheridan-Gardiner single optotype test of visual acuity (referral criterion 6/9 or worse in either eye), cover test, ocular movements, 20(Delta) prism test, and TNO stereotest. RESULTS: The overall NPV of preschool vision screening for amblyopia was 100% (95% CI 99.4% to 100%). Most children with amblyopia were detected by the Sheridan-Gardiner single optotype test of visual acuity, but the other screening tests were necessary to prevent any false negatives. In isolation, the Sheridan-Gardiner single optotype test of visual acuity has a NPV for amblyopia of only 99.6% (95% CI 98.7% to 99.9%). CONCLUSION: Preschool vision screening using a single optotype test of visual acuity does achieve a high NPV for amblyopia, but only under certain conditions. These comprise a low threshold for referral (6/9 or worse in either eye) and the inclusion of a cover test and tests of binocular function in the screening assessment.  (+info)

A deficit in strabismic amblyopia for global shape detection. (4/685)

Using a task which relied upon the detection of sinusoidal deformations from circularity, we show that strabismic amblyopes exhibit deficits which are not critically dependent on either the scale of deformation or the spatial frequency characteristics of the stimulus (circular D4) itself. We show that this loss is not due to the restricted passband of the amblyopic eye. Furthermore, in a pedestal distortion experiment, we show that the suprathreshold form of this loss is consistent with an elevated level of 'intrinsic noise' rather than a loss in 'sampling efficiency'.  (+info)

Orientation-based texture segmentation in strabismic amblyopia. (5/685)

Texture segmentation of 'target' Gabors from an array of 'background' Gabors was measured in terms of the difference in orientation between the two regions, as well as the difference in orientation within each region. Segmentation was shown to occur on the basis of local orientation differences at the boundary between the target and background regions (Nothdurft, H.C. (1992). Feature analysis and the role of similarity in preattentive vision. Perception and Psychophysics, 52, 355-375.). We obtained similar results for both the amblyopic and non-amblyopic eye of three strabismic amblyopes, and showed also that the effects of texture undersampling and positional jitter were similar for the two eyes. This pattern of results is consistent with intact mechanisms of texture perception in amblyopic cortex, and suggests also that any amblyopic deficits in first-order cortical units (undersampling and/or positional uncertainty) do not limit higher-order texture segmentation processes. Therefore, first- and second-order processes involved in perceptual grouping of oriented elements (that appear to be abnormal in amblyopic cortex; Kovacs, I., Polat, U., Norcia, A.M. (1996). Breakdown of binding mechanisms in amblyopia. Association for Research in Vision and Ophthalmology Abstracts; Mussap, A.J., Levi, D.M. (1995). Amblyopic deficits in perception of second-order orientation. Investigative Ophthalmology and Visual Science (Supplement), 36, S634; Mussap, A.J., Levi, D.M. (1998). Amblyopic deficits in perceptual grouping. Vision Research, submitted) do not contribute to texture perception based on orientation contrast.  (+info)

Position jitter and undersampling in pattern perception. (6/685)

The present paper addresses whether topographical jitter or undersampling might limit pattern perception in foveal, peripheral and strabismic amblyopic vision. In the first experiment, we measured contrast thresholds for detecting and identifying the orientation (up, down, left, right) of E-like patterns comprised of Gabor samples. We found that detection and identification thresholds were both degraded in peripheral and amblyopic vision; however, the orientation identification/detection threshold ratio was approximately the same in foveal, peripheral and amblyopic vision. This result is somewhat surprising, because we anticipated that a high degree of uncalibrated topographical jitter in peripheral and amblyopic vision would have affected orientation identification to a greater extent than detection. In the second experiment, we investigated the tolerance of human and model observers to perturbation of the positions of the samples defining the pattern when its contrast was suprathreshold, by measuring a 'jitter threshold' (the amount of jitter required to reduce performance from near perfect to 62.5% correct). The results and modeling of our jitter experiments suggest that pattern identification is highly robust to positional jitter. The positional tolerance of foveal, peripheral and amblyopic vision is equal to about half the separation of the features and the close similarity between the three visual systems argues against extreme topographical jitter. The effects of jitter on human performance are consistent with the predictions of a 'template' model. In the third experiment we determined what fraction of the 17 Gabor samples are needed to reliably identify the orientation of the E-patterns by measuring a 'sample threshold' (the proportion of samples required for 62.5% correct performance). In foveal vision, human observers are highly efficient requiring only about half the samples for reliable pattern identification. Relative to an ideal observer model, humans perform this task with 85% efficiency. In contrast, in both peripheral vision and strabismic amblyopia more samples are required. The increased number of features required in peripheral vision and strabismic amblyopia suggests that in these visual systems, the stimulus is underrepresented at the stage of feature integration.  (+info)

Abnormal depth perception from motion parallax in amblyopic observers. (7/685)

Many similarities exist between the perception of depth from binocular stereopsis and that from motion parallax. Moreover, Rogers (1984, cited in, Howard, I. P., & Rogers, B. J. (1995). Binocular vision and stereopsis. Oxford Claridon, New York.) suggests a relationship between an observer's ability to use disparity information and motion parallax information in a depth perception task. To more closely investigate this relationship, depth perception was studied in normal observers and amblyopic observers with poor stereo vision. As expected, amblyopic observers performed much worse than normal observers on depth discriminations requiring use of binocular disparity. However, amblyopic observers also performed much worse than normal observers on depth discriminations based on motion parallax. This result provides supporting evidence for a psychoanatomical link between the perception of depth from motion and the perception of depth from binocular disparity.  (+info)

Assessment of cortical dysfunction in human strabismic amblyopia using magnetoencephalography (MEG). (8/685)

The aim of this study was to use the technique of magnetoencephalography (MEG) to determine the effects of strabismic amblyopia on the processing of spatial information within the occipital cortex of humans. We recorded evoked magnetic responses to the onset of a chromatic (red/green) sinusoidal grating of periodicity 0.5-4.0 c deg-1 using a 19-channel SQUID-based neuromagnetometer. Evoked responses were recorded monocularly on six amblyopes and six normally-sighted controls, the stimuli being positioned near the fovea in the lower right visual field of each observer. For comparison, the spatial contrast sensitivity function (CSF) for the detection of chromatic gratings was measured for one amblyope and one control using a two alternate forced-choice psychophysical procedure. We chose red/green sinusoids as our stimuli because they evoke strong magnetic responses from the occipital cortex in adult humans (Fylan, Holliday, Singh, Anderson & Harding. (1997). Neuroimage, 6, 47-57). Magnetic field strength was plotted as a function of stimulus spatial frequency for each eye of each subject. Interocular differences were only evident within the amblyopic group: for stimuli of 1-2 c deg-1, the evoked responses had significantly longer latencies and reduced amplitudes through the amblyopic eye (P < 0.05). Importantly, the extent of the deficit was uncorrelated with either Snellen acuity or contrast sensitivity. Localization of the evoked responses was performed using a single equivalent current dipole model. Source localizations, for both normal and amblyopic subjects, were consistent with neural activity at the occipital pole near the V1/V2 border. We conclude that MEG is sensitive to the deficit in cortical processing associated with human amblyopia, and can be used to make quantitative neurophysiological measurements. The nature of the cortical deficit is discussed.  (+info)

This study will evaluate the effectiveness of refractive correction alone for the treatment of previously untreated strabismic or combined-mechanism amblyopia in children 3 to ,7 years old with visual acuity of 20/40 to 20/400.. A recently completed PEDIG study (ATS5) found that in 3 to , 7-year-old children with previously untreated anisometropic amblyopia, refractive correction alone improved visual acuity by 2 or more lines in 77% of the patients and amblyopia resolved in at least one third of the patients. These results supported previous observations from retrospective and pilot studies as well as Stewart et als prospective report on 18 children with anisometropic amblyopia whose visual acuity improved after treatment with spectacle correction only.. Improvement in amblyopic eye visual acuity from treatment with optimum refractive correction in cases of anisometropic amblyopia is plausible because the refractive correction treats the underlying amblyogenic condition (i.e., uncorrected ...
AIMS--The study aimed to assess the effect of initial visual acuity and type of amblyopia on the long term results of successfully treated amblyopia. METHODS--The visual acuity of 94 patients, who had been successfully treated for unilateral amblyopia by occlusion of the good eye and followed up to the age of 9 years, was examined 6.4 years, on average, after cessation of treatment. Patients were divided into two groups according to the depth of amblyopia before occlusion therapy was started: those with visual acuity between 20/60 and 20/100 and those with visual acuity of 20/100 or worse. RESULTS--Deterioration of visual acuity was observed in 42% of patients in the first group and in 63% of patients in the second group. Their average deterioration, as measured by the Snellen chart, was 0.58 and 1.54 lines, respectively. The results were also assessed by the division of patients into three groups according to the type of amblyopia: strabismic, strabismic anisometropic, and anisometropic. ...

Below is a translation into common language of a technical paper that reviewed literature on Amblyopia, commonly known as lazy eye, and then a review by Dr. Susan Barry, PhD, who is both a researcher, college professor, and an individual who had several surgeries as a young child to address her eye turn and lazy eye. As an adult, she had Vision Therapy and was then able to gain the ability to use her two eyes as a team and resolve both the amblyopia and the strabismus.. Amblyopia (lazy eye) is a neuro-developmental disorder of the visual cortex that arises from abnormal visual experience early in life. Amblyopia is clinically important because it is a major cause of vision loss in infants and young children.. Amblyopia is not a problem of the eye, but rather a brain based problem that is caused when someone does not have normal visual development. Yes, VISION DEVELOPS.. Undestanding Amblyopia and how it is fixed also helps us understand how changable the brain is, and how it can recover, for ...
Prerequisite: VT/Visual Dysfunctions VT - 1. This course supplements the core VT/Visual Dysfunctions (VT I) course with testing and therapy activities to diagnose and treat patients with strabismus and amblyopia.. For whatever reasons, strabismus and amblyopia have a reputation for being difficult to understand and treat. The approach of the OEP Clinical Curriculum stems from the understanding of Chaos and Complexity Theory which states, That which appears to be complex, most often can be explained very simply. That which appears so simple, most often is actually very complex. You will learn how specific disruptions or thwarting experiences occurring at critical times in normal infant development can result in strabismus or amblyopia. How and why do amblyopia and strabismus develop? What percentage of strabismus and amblyopia are functionally related? How can the development of amblyopia or strabismus be beneficial to the person at a specified point in time and why is this behavior not ...
Purpose : Success in treating amblyopia is critically dependent on treatment adherence. There are limited studies performed in the East African region to assess barriers to adherence with amblyopia treatment and outcomes of treatment. Our study aims to identify factors associated with higher compliance in amblyopia treatment. Methods : A hospital-based retrospective and prospective observational study was performed at the pediatric ophthalmology clinic of Menilik II Referral Hospital in Addis Ababa from March to June 2015. Included were Ethiopian children, between ages 4 and 8, with a clinical diagnosis of amblyopia defined as an interocular acuity difference of at least 0.2 logMAR. Patients with deprivation amblyopia, neurologic or traumatic eye disease or previous intraocular surgery were excluded. We collected demographic and clinical data from charts. Parents were asked to estimate the number of hours they were able to administer patching in the past week and fill out a brief questionnaire ...
One barrier to detecting amblyopia in children is that kids get used to the condition. The most common symptom of amblyopia is strabismus, commonly referred to as crossed-eyed. The vision of the straight eye becomes dominant, whereas the crossed eyes vision deteriorates. Amblyopia can be passed down genetically, and there is more of a risk if the child is born prematurely. If not treated, a patient can have increased healthcare costs, educational difficulties, permanent vision impairment and blindness. The older a child gets, usually around eight, the harder it is to avoid permanent vision impairment. With GoCheckKids, amblyopia can be detected early on. Using photoscreening or visual acuity, pediatricians can see if they are developing amblyopia and refer them to an eye care specialist. The AAP recommends annual photo screening starting at age one. The earlier amblyopia is detected, the more effective the treatment options are. Fast ...
Amblyopia is a neurodevelopmental disorder of the visual system that is caused by abnormal binocular visual experience during early childhood, typically due to anisometropia or strabismus [1]. Amblyopia causes a range of monocular deficits in the affected eye including impaired visual acuity [1], contrast sensitivity [2], motion perception [3, 4] and excessive crowding [5] (see [6] for a recent review). Patients with amblyopia also experience impaired binocular vision. In particular, the fellow eye often suppresses the amblyopic eye when both eyes are open, and stereopsis is commonly impaired or absent [7]. Stronger interocular suppression has been associated with poorer stereopsis and monocular visual acuity in patients [8-11], as well as poorer amblyopic eye contrast sensitivity in animal models of amblyopia [12, 13].. In children, the visual acuity deficit associated with amblyopia can be treated monocularly by optically correcting any significant refractive error and then occluding ...

Many people make the mistake of saying that a person who has a crossed or turned eye has a lazy eye, but amblyopia and strabismus are not the same condition. Some of the confusion may be due to the fact that an eye turn can cause lazy eye. In other words, amblyopia can result from a constant unilateral strabismus (i.e., an eye that turns or deviates all of the time). Alternating or intermittent strabismus (an eye turn which occurs only some of the time) rarely causes amblyopia.. While a deviating eye (strabismus) can be easily spotted by the layman, amblyopia without strabismus or associated with a small deviation usually can be not noticed by either you or your pediatrician. Only an eye doctor comfortable in examining young children and infants can detect this type of amblyopia. This is why early infant and pre-school eye examinations are so necessary.. Due to misunderstanding or misuse of the terms for different visual conditions (i.e., deviating eyes vs. lazy eye), many people are ...
1. Introduction 1.1 Amblyopia 1.1.1 Definition Amblyopia or „lazy eye‟ has conventionally been defined as a unilateral or bilateral decrease of visual acuity caused by deprivation of pattern vision or abnormal binocular interaction, for which no cause can be detected by physical examination of the eye and which in some cases can be reversed by therapeutic measures (1). Clinically, amblyopia is defined as a reduction in best-corrected visual acuity to less than 6/9 monocularly in Snellen optotype or as a two-line difference or more in best-corrected visual acuity between the eyes in LogMAR optotype. This compares with findings in normal subjects, in which the interocular difference in best-corrected visual acuity has been found to be less than two lines (0.2 LogMAR optotype) in both infants and adults (2). However, clinical definitions are debated with different studies using different inclusion criteria for the amblyopic subjects participated. 1.1.2 Prevalence Amblyopia is a significant ...
There is a third, rare type of amblyopia, where vision is obstructed by visual occlusions such as congenital cataracts―called deprivation amblyopia. Unlike the more common causes of lazy eye which can often be addressed without surgery, this third type must be surgically corrected to allow normal vision development.. Earlier is better when it comes to treatment. Amblyopia is not only the top cause of eye impairment in kids; it is also the most common cause of monocular (single eye) issues among young and middle-aged adults. Unless lazy eye is effectively treated in early childhood, it almost always persists into adulthood. Fortunately, prospects are bright for children who receive treatment early, between the ages of 3 and 6.. If amblyopia is left untreated, or if treatment is delayed until the preteen or early teen years, it could mean the difference between full and partial recovery. Because the brain has ignored the weaker eye for so long, retraining it becomes more difficult, and vision in ...
Academy Store. Loading, please wait Braverman, MD. Amblyopia develops during childhood and results in the interruption of normal cortical visual pathway development. The VIP study group recently published the risk factors associated with amblyopia in their cohort of children 3-5 years of age enrolled in the Head Start program. Amblyopia is defined as the reduction of best-corrected visual acuity of one or both eyes that cannot be attributed exclusively to a structural abnormality of the eye. Various causes of stimulus deprivation include eyelid ptosis, cornea opacities, cataracts, vitreous hemorrhage among others. Hispanics were found to have the highest rates of astigmatism and anisometropia, whereas non-Hispanic whites had the highest rate of hyperopia. Prevalence of amblyopia in primary school children in Qassim province, Kingdom of Saudi Arabia.. ...
Amblyopia in children with Downs syndrome has been noted in only two previous studies. Hiles and coworkers found that 11 (8.5%) of 123 patients with Downs had amblyopia,4 and Jaeger observed amblyopia in only three (13%) of 23 patients in whom reliable distance acuity was testable.3 Both of these studies involved institutionalised patients. Our study, however, is entirely composed of children brought up at home. Because we attempted to access all home reared children with Downs syndrome between 5 and 19 years of age in Rhode Island, and since there is no apparent selection bias, the results of our study may more accurately reflect the prevalence of ophthalmological problems in children with Downs syndrome in this age range.. We observed amblyopia in 15 (22%) of the 68 patients in our study group. This is a markedly higher prevalence than previously reported in patients with Downs syndrome,3 4 and also significantly increased over the 2-2.5% prevalence figure for amblyopia in the general ...
Amblyopia or lazy eye is the decreased ability to see detail. During early childhood years the nerve pathway from the eye to the brain does not develop as it should which causes this condition. Amblyopia is by far the leading cause of decreased vision in children. Amblyopia, or more commonly lazy eye, is poor vision in one or both eyes due to a lack of stimulation to the retina (the back inside surface of the eye that relays information to the brain) during the critical development period in childhood (from birth to around 7 - 8 years of age). Common underlying causes of a lack of stimulation include squint (misalignment of the eye), uncorrected refractive error (e.g. long-sightedness or astigmatism), ptosis (droopy upper eyelid obscuring the pupil) and cataract.. It is very important that amblyopia is detected early (approximately before the age of 7 - 8years) in order to try to improve the weak vision. If amblyopia is not detected before this critical age, treatment is less likely to be ...
Background: It is reported that 0.2 to 5.3% of children suffer from amblyopia. The traditional treatment for amblyopia has been to correct the refractive error and occlude the non-amblyopic eye. Compliance, however, with patching is a significant problem. The aim of this study was to investigate the parental knowledge of amblyopia and its treatment. We also wanted to explore the demographic and psychosocial impact of occlusion therapy on children with amblyopia and their parents.. Methods: Fifty-two parents and their children ages 2 to 13, undergoing occlusion therapy for amblyopia, participated in this study. Visual acuity at the initiation of occlusion therapy and the prescribed occlusion regimen were obtained from patient files. The compliance with occlusion therapy was based on self report of the parents. The emotional impact of occlusion therapy was determined by an emotional impact questionnaire. The experiences and the difficulties expressed by parents and children were noted in their own ...
Amblyopia is the leading cause of vision loss in children. It is treatable if diagnosed early, making identification of affected children critical. The American Association for Pediatric Ophthalmology and Strabismus and the American Academy of Pediatrics recommend that clinicians routinely perform age-appropriate vision chart testing, red reflex testing, and examination for signs of strabismus. The U.S. Preventive Services Task Force recommends vision screening for all children at least once between three and five years of age to detect the presence of amblyopia or its risk factors. Photoscreening may be a useful adjunct to traditional vision screening, but there is limited evidence that it improves visual outcomes. Treatments for amblyopia include patching, atropine eye drops, and optical penalization of the nonamblyopic eye. In children with moderate amblyopia, patching for two hours daily is as effective as patching for six hours daily, and daily atropine is as effective as daily patching. Children
Purpose: : Amblyopia has been defined as a developmental disorder of pattern or spatial vision associated with strabismus, anisometropia, or form deprivation during the critical period of visual development in early life. Amblyopia is generally attributed to abnormal development of the visual cortex due to strabismus, image blur from refractive error, or a combination of these factors. Retinal involvement in amblyopia is more controversial. Kittens reared with experimentally induced strabismus have shown deficits in receptive field development in retinal ganglion cells. In this investigation we measured retinal nerve fiber layer (RNFL) thickness and photopic negative response (PhNR) amplitude in pediatric and adult strabismic and anisometropic amblyopes. Methods: : Fifteen adult and 7 pediatric cases with strabismic (13 eyes) and anisometropic (9 eyes) were examined. Clinical examination including BCVA, refractive error, slit lamp exam, EOM, strabismic evaluation and IOP. RNFL was measured in ...
The gold standard treatments in amblyopia are penalizing therapies, such as patching or blurring vision with atropine that are aimed at forcing the use of the amblyopic eye. However, in the last years, new therapies are being developed and validated, such as dichoptic visual training, aimed at stimulating the amblyopic eye and eliminating the interocular supression. To evaluate the effect of dichoptic visual training using a virtual reality head mounted display in a sample of anisometropic amblyopic adults and to evaluate the potential usefulness of this option of treatment. A total of 17 subjects (10 men, 7 women) with a mean age of 31.2 years (range, 17-69 year) and anisometropic amblyopia were enrolled. Best corrected visual acuity (BCVA) and stereoacuity (Stereo Randot graded circle test) changes were evaluated after 8 sessions (40 min per session) of dichoptic training with the computer game Diplopia Game (Vivid Vision) run in the Oculus Rift OC DK2 virtual reality head mounted display (Oculus VR).
This study included 323 eyes of 164 patients. All patients underwent laser in situ keratomileusis (90.1%, 291 eyes) or photorefractive keratectomy (9.9%, 32 eyes). Three months postoperatively, the manifest spherical equivalent was −0.07 ± 0.55 diopters (D) (range: −1.75 to +1.30 D) and −0.10 ± 0.54 D (range: −2.13 to +1.30 D) in the amblyopia group and fellow eye group, respectively. The percentage of eyes achieving UDVA of 20/20 or better was 16.9% (15 eyes) in the amblyopia group and 61.9% (52 eyes) in the fellow eye group. The percentage of eyes that gained two or more lines of CDVA was 27.9% (24 eyes) in the amblyopia group and 6.2% (5 eyes) in the fellow eye group (P , .01). In the amblyopia group, there was no statistically significant difference in the mean manifest spherical equivalent between the myopic eyes and hyper-opic eyes at any follow-up visit (P = .87, 1 month postoperatively; P = .68, 3 months postoperatively).. The study concluded that the laser vision correction is ...
A nonspecific term referring to impaired vision. Major subcategories include stimulus deprivation-induced amblyopia and toxic amblyopia. Stimulus deprivation-induced amblyopia is a developmental disorder of the visual cortex. A discrepancy between visual information received by the visual cortex from each eye results in abnormal cortical development. STRABISMUS and REFRACTIVE ERRORS may cause this condition. Toxic amblyopia is a disorder of the OPTIC NERVE which is associated with ALCOHOLISM, tobacco SMOKING, and other toxins and as an adverse effect of the use of some medications ...
Patching is the standard treatment for amblyopia. An opaque, adhesive patch is worn over the stronger eye for weeks to months. This therapy forces the child to use the eye with amblyopia. Patching stimulates vision in the weaker eye and helps the part of the brain that manages vision develop more completely. Generally, the patch is prescribed for the entire day while awake except for an hour to shower or bathe. The patch is prescribed for a total period equal to about one week for every year of the childs age. For example, a five-year-old child with amblyopia will have to wear the patch for about five weeks. During this time, the vision of both eyes are frequently tested, and so the actual period may be shorter or longer by one or two weeks. Compliance with wearing the eye patch is a significant problem in the treatment of amblyopia. This may be a result of the inherent discomfort of having to see with an eye with poor vision or from the discomfort of the eye patch itself. Poor compliance may ...

A childs eyes needs regular, equal use to develop normal vision. Poor vision in an eye that did not get enough use during childhood is called amblyopia (lazy eye). Treatment during early childhood can usually reverse amblyopia. Treatment after childhood is rarely helpful. A child with amblyopia who does not get treatment will probably have poor vision for the rest of his or her life.. Amblyopia is caused by any condition that affects normal use of the eyes and visual development. In many cases, the conditions associated with amblyopia may be inherited. Children in a family with a history of amblyopia or misaligned eyes should be checked by an Ophthalmologist early in life. There are 3 major causes of amblyopia in children - strabismus (turned eye), unequal focus due to refractive error or cloudiness caused by lens or corneal opacity.. Success in the treatment of amblyopia also depends upon how severe the amblyopia is and how old the child is when treatment is begun. If the problem is detected ...
TY - JOUR. T1 - Cortical correlates of amblyopia. AU - Kiorpes, Lynne. AU - Daw, Nigel. PY - 2018/1/1. Y1 - 2018/1/1. N2 - There are many levels of disorder in amblyopic vision, from basic acuity and contrast sensitivity loss to abnormal binocular vision and global perception of motion and form. Amblyopia treatment via patching to restore acuity often leaves other aspects of vision deficient. The source for these additional deficits is unclear. Neural correlates of poor binocular function and acuity loss are found in V1 and V2. However, they are generally not sufficient to account for behaviorally measured vision loss. This review summarizes the known cortical correlates of visual deficits found in association with amblyopia, particularly those relevant to binocular vision and higher-order visual processing, in striate and extrastriate cortex. Recommendations for future research address open questions on the role of suppression and oculomotor abnormalities in amblyopic vision, and underexplored ...

PurposeRecent studies have found a choroidal thickening in amblyopic eyes and suggested that there might be a relationship between the choroid and amblyopia. The present study aimed to evaluate the effect of a six-month treatment of amblyopia on choroidal thickness in anisometropic hyperopic amblyopic children. ...
Refractive amblyopia happens when there is a large or unequal amount of refractive error (glasses strength) between a childs eyes. The brain learns how to see well from the eye that has less need for glasses and does NOT learn to see well from the eye that has a greater need for glasses. The vision problem may be invisible because the child does not complain of blurry vision. The child sees well with the better seeing eye. Additionally, the amblyopic eye may not look any different from the normal seeing eye. Therefore, parents and pediatricians may not think there is a problem because the childs eyes look normal. For these reasons, this kind of amblyopia in children may not be found until the child has a vision test. This kind of amblyopia can affect one or both eyes and can be best helped if the problem is found early.. ...
Amblyopia refers to poor vision in an eye when all other causes are discounted. Often it is confused with a squint, but amblyopia can occur even if the eyes are straight.. In amblyopia, it is important to check if glasses will sort the problem out before using occlusion. This is called Refractive Adaptation. This can take 4 months to work as unlike adults it takes some time for the brain to adapt to glasses. We only treat with Occlusion when we have the best vision from glasses.. This is also useful as the child will be able to see something rather than very little in the bad eye with occlusion and may want to continue rather than fighting with the parents.. ...
Treatment of amblyopia (lazy eye) depends on the underlying cause, if the amblyopia is caused by squint (or strabismus), the stronger eye may be patched, or covered, in order to make the amblyopic eye work harder. If the cause is very short or long sight in one eye, spectacles are prescribed, sometimes with patching. If the amblyopia is due to an ocular problem such as cataract, that condition will need to be treated. After therapy the patient may require spectacles or contact lenses to restore focusing.. ...

BACKGROUND: Many patient-reported outcome measures (PROMs) have been developed and/or used to measure the impact of amblyopia and strabismus on quality of life (QoL). Identifying the one with superior quality is important for evaluating the effectiveness of novel therapy for amblyopia and for directing improved clinical decision-making in adults considering strabismic surgery. Therefore, the aim of this review is to identify all PROMs previously developed/used to study the impact of amblyopia and/or strabismus on QoL and to appraise the quality and comprehensiveness of content of the disease-specific instruments ...

Behavioral studies have reported reduced spatial attention in amblyopia, a developmental disorder of spatial vision. However, the neural populations in the visual cortex linked with these behavioral spatial attention deficits have not been identified. Here, we use functional MRI-informed electroencephalography source imaging to measure the effect of attention on neural population activity in the visual cortex of human adult strabismic amblyopes who were stereoblind. We show that compared with controls, the modulatory effects of selective visual attention on the input from the amblyopic eye are substantially reduced in the primary visual cortex (V1) as well as in extrastriate visual areas hV4 and hMT+. Degraded attentional modulation is also found in the normal-acuity fellow eye in areas hV4 and hMT+ but not in V1. These results provide electrophysiological evidence that abnormal binocular input during a developmental critical period may impact cortical connections between the visual cortex and ...
Strabismus, sometimes also incorrectly called lazy eye, is a condition in which the eyes are misaligned.[15] Strabismus usually results in normal vision in the preferred sighting (or fellow) eye (the eye that the person prefers to use), but may cause abnormal vision in the deviating or strabismic eye due to the difference between the images projecting to the brain from the two eyes.[16] Adult-onset strabismus usually causes double vision (diplopia), since the two eyes are not fixed on the same object. Childrens brains, however, are more neuroplastic, so can more easily adapt by suppressing images from one of the eyes, eliminating the double vision. This plastic response of the brain, however, interrupts the brains normal development, resulting in the amblyopia.[citation needed] Recent evidence points to a cause of infantile strabismus lying with the input to the visual cortex.[17]. Those with strabismic amblyopia tend to show ocular motion deficits when reading, even when they use the ...

Lazy eye is a visual impairment where usually only one eye fails to achieve visual acuity (the sharpness of your vision and the ability to discern shapes and numbers from a distance).. Amblyopia starts during early childhood and if detected quickly and treated, vision wont be adversely affected. If left untreated legal blindness or a severe visual disability can develop.. Occurrences of amblyopia are rare with approximately three percent of the U.S. population experiencing some degree of lazy eye. ...
By age 3, an optometrist should reassess a childs visual system to confirm the absence of any eye disease, as well as monitor the continued growth and efficiency of visual skill development. This is also the examination where eye muscle problems such as crossed-eyes (strabismus) and lazy eye (amblyopia) are carefully assessed.. Amblyopia, or lazy eye, is the loss or lack of development of vision in an eye that is healthy. Amblyopia can be caused by crossed-eyes (strabismus), unequal refractive error, farsightedness or nearsightedness, or a physical obstruction like a cataract. The brain learns to see with the good eye only, and the other eye grows weaker from disuse. It is estimated that 2 - 4% of all children have amblyopia. Amblyopia is responsible for more cases of vision loss in children than all other ocular diseases and traumas combined. If detected and treated at an early age, amblyopia will often resolve completely.. ...
Some binocular treatments for amblyopia propose that they help children overcome interocular suppression and experience binocular vision while playing a game and possibly yield better vision outcomes. Others believe that combining a binocular game with patching demonstrates even more visual acuity (VA) improvement. However, a Chinese study has revealed that using a binocular game has no superiority in binocularity over part-time patching, and combining the two does not improve VA. For 103 Chinese anisometropic children between the ages of three and 13, researchers prescribed three months of at-home therapy. The binocular group played a binocular game for 40 minutes each day, divided into four training sessions. The patching group received two to six hours of patching of the fellow eye a day depending on the severity of amblyopia. The combined group had to complete both the binocular game and part-time patching.. The differences in VA changes were similar among the three groups, suggesting the ...
Scott was told amblyopia (lazy eye) would deteriorate his vision. Vision therapy changed his viewpoint.. It has been a couple of months since my last vision therapy appointment (and graduation!) and I wanted to thank you once again for the encouragement and inspiring atmosphere at your centre.. Dr. McCrodan, you and your staff extended every courtesy to ensure my successful treatment, and because of my hard work as well as the gentle reminders from you and your staff as to how important the homework was, I enjoy seeing my world in glorious 3D-the fall colours on the leaves of the trees are most significant when I see the trees in various spatial planes, and flying radio controlled helicopters with my friends has bloomed into a rewarding experience rather than a terrifying one due to not perceiving depth like I needed.. When I was told that by age 12 that my right eye would only deteriorate, imagine my surprise to learn that vision therapy existed and could help with my amblyopia! I cant thank ...
One or more of the following abnormalities may accompany ptosis in childhood: astigmatism (refractive error), obstruction of the visual axis (the path that light takes into the eye), a chin-up head position, and amblyopia. The abnormal resting position of the eyelid on the cornea may result in astigmatism (a misshaping of the cornea) or other refractive errors, and is a risk factor for developing amblyopia (refractive amblyopia). Another risk factor for amblyopia is an eyelid drooping so low that it actually prevents light from entering the eye and creating an image on the retina at the back of the eye (deprivation amblyopia) Also, a chin-up head position may be present. This head position is adopted in order to be able to see beneath the edge of the drooping upper eyelid. Contraction of the frontalis muscle (in the forehead) to further elevate the upper eyelid is a very common compensatory mechanism.. ...

Abstract Background  We recently developed the Amblyopia & Strabismus Questionnaire (A&SQ) to assess the quality of life in amblyopia and/or strabismus patients, and evaluated its content and criterion validity. The A&SQ was now validated clinically by correlating its outcome with past and current orthoptic parameters in a historic cohort of amblyopia and/or strabismus patients. Methods  The cohort was derived from all 471 patients who were treated by occlusion therapy in the Waterland Hospital in Purmerend between 1968 and 1974 and born between 1962 and 1972. All children with insufficient visual acuity from the Waterland area had been referred to a single ophthalmologist and orthoptist. Of these, 203 were traced, and 174 filled out the A&SQ. In 137 of these, binocular vision, visual acuity, and angle of strabismus were reassessed 30â€Â35 years after occlusion therapy. These clinical parameters were correlated with the five A&SQ domains: ...

Lazy Eye is a term commonly used to describe both Amblyopia and Strabismus (Eye Turn). Amblyopia means dull sight and refers to a condition whereby one eye sees poorly and is effectively blocked out by the visual system. This can cause an eye turn (or Strabismus) but an eye turn doesnt always occur. Most parents assume because their child can see things in the distance that both eyes must be seeing fine. This is, unfortunately, not always the case. They may actually be only using their one good eye and ignoring the image from the eye that cant see well. Parents often ask: but wouldnt my child know this? A child may not be aware of this, because they think this is the way that everyone sees. Because they are still able to see out of one eye, they dont even know to complain! ...

Moderate and high hyperopia are associated with the development of strabismus and amblyopia. The primary aims of treatment for asymptomatic moderate and high hyperopia in preschool children are to facilitate the development of normal visual acuity and to prevent the development of esotropia and amblyopia. Treatment consists of optical correction, typically using glasses. For children with high hyperopia (,+5.00D) and without strabismus or amblyopia, there is general consensus that a correction should be prescribed. Nevertheless, for children with moderate hyperopia (+3.00D to +5.00D) without strabismus or amblyopia, there is less consensus among pediatric eye care professionals. A survey by Lyons et al found that for a 2-year-old child with hyperopia greater than +3.00D, 65% of optometrists would prescribe glasses compared to 25% of ophthalmologists; for a 4-year old with hyperopia greater than +3.00D, 67% of optometrists would prescribe compared with 42% of ophthalmologists.

Three to five percent of the population has amblyopia, a.k.a. lazy eye, in which a healthy eye never learns to see because isnt used. This usually happens because of a focusing problem or subtle misalignment of that eye. The brain learns to ignore input from that eye, and unless this is noticed early, it weakens and can slowly go blind.. When I can diagnose amblyopia early enough, I can treat it with an eye patch or eye drops to block the good eye, says David Hunter, MD, PhD, chief of ophthalmology at Boston Childrens Hospital. This gives the eye with amblyopia time to catch up.. Unfortunately, eye patching doesnt work well at older ages, and kids hate the socially stigmatizing patches, which often need to be worn for more than a year. As Dean Travers, cofounder of Luminopia, put it at Boston Childrens Hospitals Innovators Showcase last week, Being a pirate isnt cool for very long. …. ...
Where participants could not reliably perform this test, fellow eye contrast was manually set to allow simultaneous perception of all game elements during binocular viewing, the researchers wrote. Binocular combination was required to successfully play the active video game. Fellow eye contrast increased proportionally by 15% each day if the game was played for at least 15 minutes and a high score of at least 1,000 points was achieved the previous day.. The placebo game presented all game elements to both eyes at full contrast, simulating a normal video game experience.. The multicenter, double-masked, randomized clinical trial involved 115 participants who were ages ≥7 years with unilateral amblyopia.. The trial design specified that the falling-blocks video game was to be played at home for 1 hour a day for 6 weeks. Change in amblyopic eye visual acuity at 6 weeks was the main measured outcome, while secondary outcomes included compliance, stereoacuity, and interocular suppression.. Of ...

It is often asked at what age should treatment no longer be attempted. The answer is, everyone deserves a chance! Age should not be a deterrent, though treatment under age 6 (especially before 2) can be ideal and could allow for better results than later treatment. After age 6, age is not important in strabismus treatment.. The best chance of success in eliminating the effects of the most difficult conditions, amblyopia or constant strabismus, occurs before the age of two. However, this does not preclude excellent success in many older patients and at least partial success in most patients older than 6 years of age. There are numerous studies that demonstrate that treatment after the age of 6 is very successful. One study compared treatment before age 6 to treatment after age 6. They found no statistical difference between the two groups. As a matter of fact, loss of an eye in patients over the age of 65 who were never treated for their amblyopia experienced a spontaneous improvement in vision ...
This report extends findings (Duffy & Mitchell, 2013) of a dramatic recovery of vision in the deprived eye of amblyopic kittens following a short dark-pulse (a 10 day period of darkness) to situations of clinical relevance. To this end, the initial deprivation began at post-natal day 7 rather than post-natal day 30. As before, the dark-pulse was imposed either immediately after the initial monocular deprivation, or was delayed several weeks after stable amblyopia was establsihed. In some animals, this dark-pulse was shortened, or disrupted by short periods of daily binocular visual experience. The effects on the visual acuity and alignment acuity of the two eyes were documented as well as the effects on binocular depth perception. The benefits of a short dark-pulse were identical to those of the prior study. A dark-pulse of 5 days was ineffective as was a dark-pulse interrupted daily by light for 30-minutes ...
