It is also used in the treatment of MIGRAINE DISORDERS and tremor.Cerebral Cortex: The thin layer of GRAY MATTER on the surface of the CEREBRAL HEMISPHERES that develops from the TELENCEPHALON and folds into gyri and sulchi. It reaches its highest development in humans and is responsible for intellectual faculties and higher mental functions.Computer Simulation: Computer-based representation of physical systems and phenomena such as chemical processes.False Positive Reactions: Positive test results in subjects who do not possess the attribute for which the test is conducted. The labeling of healthy persons as diseased when screening in the detection of disease. (Last, A Dictionary of Epidemiology, 2d ed)Pituitary Apoplexy: The sudden loss of blood supply to the PITUITARY GLAND, leading to tissue NECROSIS and loss of function (PANHYPOPITUITARISM). The most common cause is hemorrhage or INFARCTION of a PITUITARY ADENOMA. It can also result from acute hemorrhage into SELLA TURCICA due to HEAD TRAUMA; INTRACRANIAL HYPERTENSION; or other acute effects of central nervous system hemorrhage. Clinical signs include severe HEADACHE; HYPOTENSION; bilateral visual disturbances; UNCONSCIOUSNESS; and COMA.Memory: Complex mental function having four distinct phases: (1) memorizing or learning, (2) retention, (3) recall, and (4) recognition. Clinically, it is usually subdivided into immediate, recent, and remote memory.Automation: Controlled operation of an apparatus, process, or system by mechanical or electronic devices that take the place of human organs of observation, effort, and decision. (From Webster's Collegiate Dictionary, 1993)Nerve Compression Syndromes: Mechanical compression of nerves or nerve roots from internal or external causes. These may result in a conduction block to nerve impulses (due to MYELIN SHEATH dysfunction) or axonal loss. The nerve and nerve sheath injuries may be caused by ISCHEMIA; INFLAMMATION; or a direct mechanical effect.Signal Detection, Psychological: Psychophysical technique that permits the estimation of the bias of the observer as well as detectability of the signal (i.e., stimulus) in any sensory modality. (From APA, Thesaurus of Psychological Index Terms, 8th ed.)Eye Movement Measurements: Methods and procedures for recording EYE MOVEMENTS.Vitrectomy: Removal of the whole or part of the vitreous body in treating endophthalmitis, diabetic retinopathy, retinal detachment, intraocular foreign bodies, and some types of glaucoma.Injections, Intraocular: The administration of substances into the eye with a hypodermic syringe.Sensory Aids: Devices that help people with impaired sensory responses.Anticonvulsants: Drugs used to prevent SEIZURES or reduce their severity.Motion: Physical motion, i.e., a change in position of a body or subject as a result of an external force. It is distinguished from MOVEMENT, a process resulting from biological activity.Onchocerciasis, Ocular: Filarial infection of the eyes transmitted from person to person by bites of Onchocerca volvulus-infected black flies. The microfilariae of Onchocerca are thus deposited beneath the skin. They migrate through various tissues including the eye. Those persons infected have impaired vision and up to 20% are blind. The incidence of eye lesions has been reported to be as high as 30% in Central America and parts of Africa.Neuronal Plasticity: The capacity of the NERVOUS SYSTEM to change its reactivity as the result of successive activations.Lenses: Pieces of glass or other transparent materials used for magnification or increased visual acuity.Electrophysiology: The study of the generation and behavior of electrical charges in living organisms particularly the nervous system and the effects of electricity on living organisms.ROC Curve: A graphic means for assessing the ability of a screening test to discriminate between healthy and diseased persons; may also be used in other studies, e.g., distinguishing stimuli responses as to a faint stimuli or nonstimuli.Craniopharyngioma: A benign pituitary-region neoplasm that originates from Rathke's pouch. The two major histologic and clinical subtypes are adamantinous (or classical) craniopharyngioma and papillary craniopharyngioma. The adamantinous form presents in children and adolescents as an expanding cystic lesion in the pituitary region. The cystic cavity is filled with a black viscous substance and histologically the tumor is composed of adamantinomatous epithelium and areas of calcification and necrosis. Papillary craniopharyngiomas occur in adults, and histologically feature a squamous epithelium with papillations. (From Joynt, Clinical Neurology, 1998, Ch14, p50)Expert Systems: Computer programs based on knowledge developed from consultation with experts on a problem, and the processing and/or formalizing of this knowledge using these programs in such a manner that the problems may be solved.Reference Values: The range or frequency distribution of a measurement in a population (of organisms, organs or things) that has not been selected for the presence of disease or abnormality.Movement: The act, process, or result of passing from one place or position to another. It differs from LOCOMOTION in that locomotion is restricted to the passing of the whole body from one place to another, while movement encompasses both locomotion but also a change of the position of the whole body or any of its parts. Movement may be used with reference to humans, vertebrate and invertebrate animals, and microorganisms. Differentiate also from MOTOR ACTIVITY, movement associated with behavior.Optic Lobe, Nonmammalian: In invertebrate zoology, a lateral lobe of the FOREBRAIN in certain ARTHROPODS. In vertebrate zoology, either of the corpora bigemina of non-mammalian VERTEBRATES.

April 5, 2011 in Ophthalmology. The sensitivity of automated threshold perimetry for detecting visual field defects is very high. Many otherwise normal patients have a visual field that may be abnormal because of the large number of artifacts that can occur during automated visual field testing. Figure 214-1 Printout of a normal visual field from the Humphrey Visual Field Analyzer. There are no probability symbols in either the total or pattern deviation, indicating that the threshold value of each test location is within the normal range for the patient’s age. Automated perimetry in patients with poor reliability has lower specificity and sensitivity for the detection of visual field defects. The Glaucoma Hemifield Test shows “abnormally high sensitivity.” There are many probability symbols in the pattern deviation not seen in the total deviation. The total deviation shows many probability symbols, most of which are not found in the pattern deviation. The ...

*  Meridian (perimetry, visual field)
Meridian perimetry, visual field. Meridian perimetry, visual field. 'Meridian' plural: "meridians" is used in 'perimetry' and in specifying 'visual fields'. In perimetry, the observer's eye is considered to be at the centre of an imaginary sphere. More precisely, the centre of the sphere is in the centre of the pupil of the observer's eye. The visual field can be considered to be all parts of the sphere for which the observer can see a particular test stimulus. In perimetric testing, a section of the imaginary sphere is realized as a hemisphere in the centre of which is a fixation point. The origin corresponds to the point on which the observer is fixating. The polar angle is considered to be zero degree s when a locus is horizontally to the right of the fixation point and to increase to a maximum of 360 degrees going anticlockwise. For example, the horizontal meridian runs from the observer's left, through the fixation point, and to the observer's right. The vertical ...

ag.algebraic geometry - Simple abelian varieties over non algebraically closed fields. MathOverflow Meta. Stack Exchange. Help Center Detailed answers to any questions you might have. MathOverflow Questions. Simple abelian varieties over non algebraically closed fields. I was wondering what people would normally mean by a simple abelian variety $A$ where $A$ is defined over a field $k$ that is not algebraically closed. But depending on the definition of simple it might be so that $Res {K/\mathbb Q}E$ is never simple as variety over $\mathbb Q$. ag.algebraic-geometry abelian-varieties share. Indeed $A=\operatorname{Res} {K/\mathbf{Q}} E$ is never absolutely simple, since $A {\overline{K}}$ is isomorophic over $\overline{K}$ to the product of the conjugates of $E$. You're right: "simple abelian variety $A/K$" is ambiguous when $K$ is not algebraically closed. If you do encounter "simple abelian variety $A/K$" in the literature, then in my experience it usually means "geometrically simple". So, in ...

*  Comprehending the eye chart - Chroniques de Galactica
Among the most knowledgeable plans associated with vision is the Snellen eye plan, created by Dutch eye doctor Hermann Snellen in 1862 to determine visual acuity- how well you could see at various proximities. When taking a vision exam, one eye is covered and you are asked to read read through letters of each row aloud out loud at the top leading the chart. The term 20/20 eyesight is made use of to suggest the clearness and sharpness of your eyesight measured at a proximity of 20 feet. You could see plainly at 20 feet objects that could normally be seen at that proximity if you have 20/20 vision. If you have 20/40 eyesight, it suggests that you should be as close as 20 feet to see what a person with normal vision can see at 40 feet. Some people could see well at a distance, but also are incapable to deliver nearer items in to concentration, while others could see items that are close, but also could not see them far. By having you review the chart, your eye doctor has the ability to establish whether ...

This chart was developed at the National Vision Research Institute of Australia in 1976, and is designed to enable a more accurate estimate of acuity as compared to other charts e.g., the Snellen chart. An observer who can resolve details as small as 1 minute of visual angle scores LogMAR 0, since the base-10 logarithm of 1 is 0; an observer who can resolve details as small as 2 minutes of visual angle i.e., reduced acuity scores LogMAR 0.3, since the base-10 logarithm of 2 is 0.3; and so on. History Relation to the Snellen chart Recording visual acuity using the LogMAR chart Advantages of LogMAR over other charts Low vision and blindness definition with LogMAR References External links. A Snellen score of 6/6 20/20, indicating that an observer can resolve details as small as 1 minute of visual angle, corresponds to a LogMAR of 0 since the base-10 logarithm of 1 is 0 ; a Snellen score of 6/12 20/40, indicating an observer can resolve details as small 2 minutes of visual ...

... Visual Acuity natural improvement - Little known secrets on how to improve with Herbs, Vitamins, and natural Supplements. by Ray Sahelian, M.D. June 28 2014 Do you remember how crisp, sharp, and beautiful scenery and objects looked years ago. Do you now find that some of the enchantment from looking has faded. As we age, our visual acuity weakens. This is due to a number of factors, including in part to degeneration of nerve cells in the eyes. A castle in Europe, a swan floating on a still pond, a delicate daisy, or rugged mountain scenery may not impress us as much. We lose our ability to notice fine details and differentiate subtle shades of colors. Has this enchantment disappeared forever, or are there ways to return the visual acuity magic that life offers. Can certain eyesight problems be reversed. After years of supervising patients who take eyesight pills and trying various herbs and nutrients myself, I am now aware of many that have an positive effect on visual ...

New formula connects optical quality with visual acuity May 15, 2008 For the first time, a study combines measurements of abnormalities in the eye with models for assessing how well an individual can see, meaning it may be possible to program a machine to automatically produce prescriptions for corrective lenses. The model for predicting visual clarity — based on measurements taken by today’s highly accurate aberrometers — could also enable surgeons to more accurately assess and correct the vision of patients undergoing lasik or refractive surgery. New technology in aberrometers means ophthalmologists and others can accurately measure refractive error and other abnormalities in the eye’s optics. But these instruments cannot use these measurements to predict visual acuity, or how well a person can actually see. A study recently published in the online, peer-reviewed Journal of Vision www.journalofvision.org/8/4/17, published ...

*  Preferential hyperacuity perimetry
... 'Preferential hyperacuity perimetry' is a psychophysical test used to identify and quantify visual abnormalities such as metamorphopsia and scotoma. Background PHP Technology PHP Test References. Vision abnormalities such as metamorphopsia distortions and scotoma are symptoms of retinal diseases such as Macular degeneration. 1 Because of complex brain mechanisms such as Filling-in, patients with small and peripheral defects in their vision are often unaware of such changes until late stages in the disease. Preferential hyperacuity perimetry PHP is a technology that bypasses Filling-in and quantifies the extent of visual abnormalities. 3 PHP Technology. PHP takes advantage of visual 'hyperacuity', also known as Vernier acuity —the ability to identify the misalignment of visual objects. Visual hyperacuity is at least 10-times more sensitive than Visual acuity, the ability to separate between distinct objects. 4 Therefore, in retinal diseases such as Macular ...

(1/4118) On the neural correlates of visual perception.

Neurological findings suggest that the human striate cortex (V1) is an indispensable component of a neural substratum subserving static achromatic form perception in its own right and not simply as a central distributor of retinally derived information to extrastriate visual areas. This view is further supported by physiological evidence in primates that the finest-grained conjoined representation of spatial detail and retinotopic localization that underlies phenomenal visual experience for local brightness discriminations is selectively represented at cortical levels by the activity of certain neurons in V1. However, at first glance, support for these ideas would appear to be undermined by incontrovertible neurological evidence (visual hemineglect and the simultanagnosias) and recent psychophysical results on 'crowding' that confirm that activation of neurons in V1 may, at times, be insufficient to generate a percept. Moreover, a recent proposal suggests that neural correlates of visual awareness must project directly to those in executive space, thus automatically excluding V1 from a related perceptual space because V1 lacks such direct projections. Both sets of concerns are, however, resolved within the context of adaptive resonance theories. Recursive loops, linking the dorsal lateral geniculate nucleus (LGN) through successive cortical visual areas to the temporal lobe by means of a series of ascending and descending pathways, provide a neuronal substratum at each level within a modular framework for mutually consistent descriptions of sensory data. At steady state, such networks obviate the necessity that neural correlates of visual experience project directly to those in executive space because a neural phenomenal perceptual space subserving form vision is continuously updated by information from an object recognition space equivalent to that destined to reach executive space. Within this framework, activity in V1 may engender percepts that accompany figure-ground segregations only when dynamic incongruities are resolved both within and between ascending and descending streams. Synchronous neuronal activity on a short timescale within and across cortical areas, proposed and sometimes observed as perceptual correlates, may also serve as a marker that a steady state has been achieved, which, in turn, may be a requirement for the longer time constants that accompany the emergence and stability of perceptual states compared to the faster dynamics of adapting networks and the still faster dynamics of individual action potentials. Finally, the same consensus of neuronal activity across ascending and descending pathways linking multiple cortical areas that in anatomic sequence subserve phenomenal visual experiences and object recognition may underlie the normal unity of conscious experience.  (+info)

(2/4118) Transient and permanent deficits in motion perception after lesions of cortical areas MT and MST in the macaque monkey.

We examined the nature and the selectivity of the motion deficits produced by lesions of extrastriate areas MT and MST. Lesions were made by injecting ibotenic acid into the representation of the left visual field in two macaque monkeys. The monkeys discriminated two stimuli that differed either in stimulus direction or orientation. Direction and orientation discrimination were assessed by measuring thresholds with gratings and random-dots placed in the intact or lesioned visual fields. At the start of behavioral testing, we found pronounced, motion-specific deficits in thresholds for all types of moving stimuli, including pronounced elevations in contrast thresholds and in signal-to-noise thresholds measured with moving gratings, as well as deficits in direction range thresholds and motion coherence measured with random-dot stimuli. In addition, the accuracy of direction discrimination was reduced at smaller spatial displacements (i.e. step sizes), suggesting an increase in spatial scale of the residual directional mechanism. Subsequent improvements in thresholds were seen with all motion stimuli, as behavioral training progressed, and these improvements occurred only with extensive behavioral testing in the lesioned visual field. These improvements were particularly pronounced for stimuli not masked by noise. On the other hand, deficits in the ability to extract motion from noisy stimuli and in the accuracy of direction discrimination persisted despite extensive behavioral training. These results demonstrate the importance of areas MT and MST for the perception of motion direction, particularly in the presence of noise. In addition, they provide evidence for the importance of behavioral training for functional recovery after cortical lesions. The data also strongly support the idea of functional specialization of areas MT and MST for motion processing.  (+info)

(3/4118) Retinotopic mapping of lateral geniculate nucleus in humans using functional magnetic resonance imaging.

Subcortical nuclei in the thalamus, which play an important role in many functions of the human brain, provide challenging targets for functional mapping with neuroimaging techniques because of their small sizes and deep locations. In this study, we explore the capability of high-resolution functional magnetic resonance imaging at 4 Tesla for mapping the retinotopic organization in the lateral geniculate nucleus (LGN). Our results show that the hemifield visual stimulation only activates LGN in the contralateral hemisphere, and the lower-field and upper-field visual stimulations activate the superior and inferior portion of LGN, respectively. These results reveal a similar retinotopic organization between the human and nonhuman primate LGN and between LGN and the primary visual cortex. We conclude that high-resolution functional magnetic resonance imaging is capable of functional mapping of suborganizations in small nuclei together with cortical activation. This will have an impact for studying the thalamocortical networks in the human brain.  (+info)

(4/4118) Early visual experience shapes the representation of auditory space in the forebrain gaze fields of the barn owl.

Auditory spatial information is processed in parallel forebrain and midbrain pathways. Sensory experience early in life has been shown to exert a powerful influence on the representation of auditory space in the midbrain space-processing pathway. The goal of this study was to determine whether early experience also shapes the representation of auditory space in the forebrain. Owls were raised wearing prismatic spectacles that shifted the visual field in the horizontal plane. This manipulation altered the relationship between interaural time differences (ITDs), the principal cue used for azimuthal localization, and locations of auditory stimuli in the visual field. Extracellular recordings were used to characterize ITD tuning in the auditory archistriatum (AAr), a subdivision of the forebrain gaze fields, in normal and prism-reared owls. Prism rearing altered the representation of ITD in the AAr. In prism-reared owls, unit tuning for ITD was shifted in the adaptive direction, according to the direction of the optical displacement imposed by the spectacles. Changes in ITD tuning involved the acquisition of unit responses to adaptive ITD values and, to a lesser extent, the elimination of responses to nonadaptive (previously normal) ITD values. Shifts in ITD tuning in the AAr were similar to shifts in ITD tuning observed in the optic tectum of the same owls. This experience-based adjustment of binaural tuning in the AAr helps to maintain mutual registry between the forebrain and midbrain representations of auditory space and may help to ensure consistent behavioral responses to auditory stimuli.  (+info)

(5/4118) Test-retest variability of frequency-doubling perimetry and conventional perimetry in glaucoma patients and normal subjects.

PURPOSE: To compare the test-retest variability characteristics of frequency-doubling perimetry, a new perimetric test, with those of conventional perimetry in glaucoma patients and normal control subjects. METHODS: The study sample contained 64 patients and 47 normal subjects aged 66.16+/-11.86 and 64.26+/-7.99 years (mean +/- SD), respectively. All subjects underwent frequency-doubling perimetry (using the threshold mode) and conventional perimetry (using program 30-2 of the Humphrey Field Analyzer; Humphrey Instruments, San Leandro, CA) in one randomly selected eye. Each test was repeated at 1-week intervals for five tests with each technique over 4 weeks. Empirical 5th and 95th percentiles of the distribution of threshold deviations at retest were determined for all combinations of single tests and mean of two tests, stratified by threshold deviation. The influence of visual field eccentricity and overall visual field loss on variability also were examined. RESULTS: Mean test time with frequency-doubling perimetry in patients and normal control subjects was 5.90 and 5.25 minutes, respectively, and with conventional perimetry was 17.20 and 14.01 minutes, respectively. In patients, there was a significant correlation between the results of the two techniques, in the full field and in quadrants, whereas in normal subjects there was no such correlation. In patients, the retest variability of conventional perimetry in locations with 20-dB loss was 120% (single tests) and 127% (mean tests) higher compared with that in locations with 0-dB loss. Comparative figures for frequency-doubling perimetry were 40% and 47%, respectively. Variability also increased more with threshold deviation in normal subjects tested with conventional perimetry. In both patients and normal subjects, variability increased with visual field eccentricity in conventional perimetry, but not in frequency-doubling perimetry. Both techniques showed an increase in variability with overall visual field damage. CONCLUSIONS: Frequency-doubling perimetry has different test-retest variability characteristics than conventional perimetry and may have potential for monitoring glaucomatous field damage.  (+info)

(6/4118) Selective horizontal dysmetropsia following prestriate lesion.

We describe a patient (P.S.) who, following a right prestriate lesion, reported that objects in the left visual field appeared distorted and smaller than those on the right. Other aspects of visual processing were remarkably unaffected. We carried out a series of size comparison tests using simple or complex stimuli and requiring different types of behavioural responses. We found that P.S. significantly underestimated the size of stimuli presented in her left visual field. When comparison tasks involved stimuli placed along the vertical axis or in the right visual field, P.S. performed well. The vertical and horizontal components of size distortion were found to be differentially affected. We conclude that size processing may be dissociated from other aspects of visual processing, such as form or colour processing, and depends critically on part of the occipital, prestriate areas (Brodmann areas 18-19).  (+info)

(7/4118) Evaluation of focal defects of the nerve fiber layer using optical coherence tomography.

OBJECTIVE: To analyze glaucomatous eyes with known focal defects of the nerve fiber layer (NFL), relating optical coherence tomography (OCT) findings to clinical examination, NFL and stereoscopic optic nerve head (ONH) photography, and Humphrey 24-2 visual fields. DESIGN: Cross-sectional prevalence study. PARTICIPANTS: The authors followed 19 patients in the study group and 14 patients in the control group. INTERVENTION: Imaging with OCT was performed circumferentially around the ONH with a circle diameter of 3.4 mm using an internal fixation technique. One hundred OCT scan points taken within 2.5 seconds were analyzed. MAIN OUTCOME MEASURES: Measurements of NFL thickness using OCT were performed. RESULTS: In most eyes with focal NFL defects, OCTs showed significant thinning of the NFL in areas closely corresponding to focal defects visible on clinical examination, to red-free photographs, and to defects on the Humphrey visual fields. Optical coherence tomography enabled the detection of focal defects in the NFL with a sensitivity of 65% and a specificity of 81%. CONCLUSION: Analysis of NFL thickness in eyes with focal defects showed good structural and functional correlation with clinical parameters. Optical coherence tomography contributes to the identification of focal defects in the NFL that occur in early stages of glaucoma.  (+info)

(8/4118) Cross-correlation study of the temporal interactions between areas V1 and V2 of the macaque monkey.

Cross-correlation studies performed in cat visual cortex have shown that neurons in different cortical areas of the same hemisphere or in corresponding areas of opposite hemispheres tend to synchronize their activities. The presence of synchronization may be related to the parallel organization of the cat visual system, in which different cortical areas can be activated in parallel from the lateral geniculate nucleus. We wanted to determine whether interareal synchronization of firing can also be observed in the monkey, in which cortical areas are thought to be organized in a hierarchy spanning different levels. Cross-correlation histograms (CCHs) were calculated from pairs of single or pairs of multiunit activities simultaneously recorded in areas V1 and V2 of paralyzed and anesthetized macaque monkeys. Moving bars and flashed bars were used as stimuli. The shift predictor was calculated and subtracted from the raw CCH to reveal interactions of neuronal origin in isolation. Significant CCH peaks, indicating interactions of neuronal origin, were obtained in 11% of the dual single-unit recordings and 46% of the dual multiunit recordings with moving bars. The incidence of nonflat CCHs with flashed bars was 29 and 78%, respectively. For the pairs of recording sites where both flashed and moving stimuli were used, the incidences of significant CCHs were very similar. Three types of peaks were distinguished on the basis of their width at half-height: T (<16 ms), C (between 16 and 180 ms), and H peaks (>180 ms). T peaks were very rarely observed (<1% in single-unit recordings). H peaks were observed in 7-16% of the single-unit CCHs, and C peaks in 6-16%, depending on the stimulus used. C and H peaks were observed more often when the receptive fields were overlapping or distant by <2 degrees. To test for the presence of synchronization between neurons in areas V1 and V2, we measured the position of the CCH peak with respect to the origin of the time axis of the CCH. Only in the case of a few T peaks did we find displaced peaks, indicating a possible drive of the V2 neuron by the simultaneously recorded V1 cell. All the other peaks were either centered on the origin or overlapped the origin of time with their upper halves. Thus similarly to what has been reported for the cat, neurons belonging to different cortical areas in the monkey tend to synchronize the time of emission of their action potentials with three different levels of temporal precision. For peaks calculated from flashed stimuli, we compared the peak position with the difference between latencies of V1 and V2 neurons. There was a clear correlation for single-unit pairs in the case of C peaks. Thus the position of a C peak on the time axis appears to reflect the order of visual activation of the correlated neurons. The coupling strength for H peaks was smaller during visual drive compared with spontaneous activity. On the contrary, C peaks were seen more often and were stronger during visual stimulation than during spontaneous activity. This suggests that C-type synchronization is associated with the processing of visual information. The origin of synchronized activity in a serially organized system is discussed.  (+info)

stimuli


  • We show that the presence of action relations between stimuli helps reduce visual extinction in patients with limited attention to the contralesional side of space, while the first saccades made by normal observers and early perceptual and attentional responses measured using electroencephalography/event-related potentials are modulated by preparation of action and by seeing objects being grasped correctly or incorrectly for action. (royalsocietypublishing.org)

  • The great majority of studies of human visual attention have used relatively simple stimuli and examined the effects of what we might think of as low-level properties of these stimuli-for example, their brightness and contrast relative to local neighbours, the presence of particular types of motion (e.g. looming versus receding) and whether the stimuli share local grouping properties, as set out originally by the Gestalt psychologists.

How a visual field examination for an eye is conducted?


  • I have just been given an appointment to undergo a visual field examination on both eyes. I am a liitle worried. I wish to know how the examination is conducted and what do I expect from the results.
  • Hi, I used to work at Vision Express and Dollond and Aitchison opticians as an optometry associate. The visual field examination is nothing to worry about. It is completely non-invasive and not painful, meaning they are not going to put anything in your eyes or poke you about. It's used to test your peripheral vision. To know what your peripheral vision is try this; look straight ahead at a chosen point. Now lift your hand to the side of your head. Keep looking at the point. Wiggle your fingers, you will notice that you can see your fingers wiggling at the edge of your vision. This field of vision is called peripheral. What to expect when you go for your test; you will be shown into a darkened room with a large box like machine on a table. It will have an open front. This is called a DICON machine. The assitant will explain that there is a screen inside the box which you will be able to see by looking straight ahead of you into the box. She will then explain that during the test a constant light will appear on the screen. You must follow this light with your eyes as it moves around the screen. During the test, other lights will flash up around the constant dot. You will be given a button and asked to press it the same number of times as the number of lights you see, excluding the constant light. When she is happy that you understand and possibly after a short demonstration, the assistant will ask you to put a patch over one of your eyes and rest your head against the machine. Then she will start the test. After you have finished on that eye. She will come back and cover the other eye so you can do the test with your other eye. When you are finished, the machine will print out the results which look like two grey circles. This shows the optician how much you can see in your peripheral vision. Poor peripheral vision can be a sign of glaucoma which is a disease of the eye that causes tunnel vision but can be controlled if caught early. Therefore everyone over the age of 25 should be offered a visual field exam when they go for an eye test. Don't worry about it, I'm sure it will be fine.


Is It True That The Bigger The Visual Field Defect, The Worser The Brain Is Dameged?


  • Is it true that the more the brain is dameged the worser the visual field defect is? When the decfect is caused by brain damege from Cerebral Palsy/ Stroke.
  • That is a very difficult question to answer. Loss of visual field can have many causes and it depends on which part of the connection between the eye and the brain is affected. Most visual field defects are due to problems with the retina at the back of the eye, or with the optic nerve. If you follow the nervous pathway further back, then tumours of the pituitary gland can cause field loss. Yet further into the brain and causes are tumours and stroke. Finally, injury or a lesion in the occipital lobe of the brain, located at the back of the skull, can cause what is called cortical blindness. But generally speaking the size of the defect depends on where the damage is rather than the amount of damage. Sorry, I can't be more specific without further details.

What does checking eye pressure involve?


  • I am getting my eye pressure checked on Monday , along with a visual fields , and i'm just wondering what all goes on in have your pressure taken ? i somethings get jumpy/nervous when at the doctors, and dont want to jump when they are taking the pressure.
  • There are different ways for doctors to take pressures and do visual fields. Pressures can be tested with the "puff" (non contact tonometry). You will put your head into a headrest in front of a machine that will blow a small puff of air onto your eye. It doesn't hurt at all, but it will make you jump because it's unexpected. That's okay, though; everybody jumps on this kind of test. ;) Another way to take pressures is to use a small tip that gently presses against your cornea (Goldman tonometry). While you have your head in a headrest, the optometrist will use a machine to do this. This one also doesn't hurt and is very quick. You don't even feel it. All you have to do is hold still. Visual fields are usually tested with a machine that you look into and press a button when you see a light or lines. There will be some kind of stimuli in your peripheral vision (the light or lines) and you just click when you notice them while fixating your vision straight ahead. Different kinds of tests test visual fields in different ways, so it really depends on how your optometrist wants to do it. This also doesn't hurt, and you should try to relax as much as possible. (Following the doctor's finger is NOT a visual field test; it is a test for your eye muscles.) These tests are usually part of a regular eye exam, so don't get too nervous. None of this should hurt, so let the doctor know if it does for some reason, but really you will be fine. Good luck!


How do optomitrists figure the percentage of vision loss for someone with glaucoma?


  • I know I have vision loss and I asked what per cent of loss I have and the doctor said she doesn't go by the percentages. She said the center alone was 30%. My visual field loss is in the shape of an L--and she's most concerned with the line across----WHY? p.s. I didn't dream this percentage thing up---I've seen it discussed on glaucoma groups.
  • there is no "percentage" loss, not an obvious, measurable one like you're asking for. sounds like your OD just guesstimated b/c you asked. "My visual field loss is in the shape of an L--and she's most concerned with the line across----WHY?" glaucoma causes vision loss. not awesomely-predictable vision loss. this is not nearly as cut-&-dried as you're making it out to be. all you can do is: take your drops religiously & do what your doc says.


What are the small bright spots I see when I look at the sky or a computer screen?


  • When I look at the sky or a computer screen I see numerous very tiny brights spots bouncing around my visual field. What causes this? More info: they are not floaters they are very very tiny quick moving specs.
  • not sure about the sky, but on the computer, its the light emmited from the pixels that acts as a sort of optical illusion on your eyesight. It is like those ones where the black dots appear in the grid. Sunlight probably has the same effect due to a contrast of sunlight on the atmosphere, after all, the sky isnt actually blue, its just the light that gives it that appearance.


Can you guys help me with this clinical analysis type of question?


  • If the axons of the LEFT OPTIC TRACT are destroyed, which part of the visual field is affected or blinded? I have little knowledge about the visual system so I'm not sure what to answer. Thanks guys!
  • The L optic tract contains nerves arising from the R nasal retina and the L temporal retina... which means it will affect the R eye's R field, and the L eye's R field. So in the end.. .it's the R field of both eyes.
