this may be due to ocular or neurological problems, the most common and important of them are elevated intraocular pressure (such as glaucoma), damage to the optic nerve pathway, Increased cerebrospinal fluid pressure and optic neuritis (inflammation of the optic nerve). (noorvision.om)
Over the past decade, there has been a steady rise in the number of pediatric ophthalmologists preferring primary intraocular lens (IOL) implantation in children younger than 2 years undergoing cataract surgery. (entokey.com)
It is likely that ophthalmologists and optometrists will incorporate the technology into their vision screening protocols. (ophthalmologytimes.com)
Assessment2
We anticipate the technology will be widely used in paediatric vision assessment. (ophthalmologytimes.com)

(tractorgallery.net)
Lens7
The ciliary muscles must contract to adjust for near vision, which causes the eye's crystalline lens, which is flexible, to be squashed. (retinalaser.com)
For distant vision, the ciliary muscle must relax and the eye's crystalline lens is stretched out. (retinalaser.com)
It is an over focusing, over stimulation of the focusing action of the crystalline lens causing an inability to relax the focusing system which may result in blurry vision when focusing at distance objects. (retinalaser.com)
Treatment includes a low plus lens and/or vision therapy. (retinalaser.com)
To evaluate safety and visual outcomes in surgically aphakic children undergoing secondary intraocular lens (IOL) implantation. (entokey.com)
During the Renaissance, the organ of vision was transferred from the lens to the optic nerve, which was generally believed to be on the axis of the eye. (nature.com)
the retina's rich supply of blood vessels performed a nutritive function since the crystalline humour (lens) was the organ of vision. (nature.com)
Optic nerve1
The acuity of central vision (at the optic disc) was explained by the concentration of visual spirit where the optic nerve met the retina. (nature.com)
Binocular2
It can be due to refractive error, binocular fusion abnormalities, or neuromuscular anomalies of ocular movements. (nih.gov)
The optic nerves came together at the chiasma (from the Greek letter × -chi) in order to produce a single impression in binocular vision but did not interchange. (nature.com)
Acuity1
For example, if your visual acuity is 20/100 that means that the line you correctly read at 20 feet could be read by a person with normal vision at 100 feet. (retinalaser.com)
Primary1
Retinoblastoma is the most common primary ocular malignancy (eye cancer) of childhood. (medscape.com)
Common1
The most common sign or symptom is blurred vision after prolonged near work such as reading and using a computer. (retinalaser.com)
Point3
Dr Angshuman discussed the significance of posterior polar cataract and said that it is located at a point where it affects a person's vision earlier than in other types of cataract. (ijcp.in)
If that part of the visual field is working, the patient will look at the new point (fixation saccade) and the machine will record that this has been done accurately. (ophthalmologytimes.com)
If only one camera setup is to be used for all external ocular photographic assignments, then one with a point source type of electronic flash is more universally applicable. (medscape.com)
Control3
Heterophoria is defined as an ocular deviation kept in control by a fusional mechanism. (nih.gov)
Objective Several studies report evidence for training-related neuroplasticity in the visual cortex, while other studies suggest that improvements simply reflect inadequate eye fixation control during perimetric prediagnostics and postdiagnostics. (bmj.com)
For these reasons, the control of blindness in children is considered a high priority in the World Health Organisation's (WHO) Vision 2020 initiative: The Right to Sight [5]. (heraldopenaccess.us)
Restore1
The removal of mechanical force can partially restore vision. (bvsalud.org)
Normal2
Strabismus is defined as acquired if the deviation is noticed after 6 months of age, following a presumed normal ocular alignment. (nih.gov)
Other symptoms include holding near work closer than normal, headaches with near work (such as reading or using a computer), eyestrain associated with near work, and possible double vision. (retinalaser.com)
Patient2
He detailed the requirements for ERG as: positioning of patient at 100 cm, light adapted patients, nondilated pupils, fixation (excessive blinking to be avoided), appropriate optical correction for 100 cm viewing distance, and 100-300 artefact free sweeps. (ijcp.in)
Vitrectomy was performed on the patient to address progressive vision loss, which improved the patient's vision. (bvsalud.org)
Central1
Steady fixation on a central target, and responding by pressing a buzzer when a peripheral test stimulus is displayed can be extremely difficult, or impossible for young children, the very elderly and adults with learning difficulties. (ophthalmologytimes.com)
Include1
The symptoms include light scattering, increasing glare, difficulty in reading fine prints, difficulty in vision in bright light. (ijcp.in)
Surgery2
Eyes with aphakia after surgery for traumatic cataracts and other associated ocular comorbidities were excluded. (entokey.com)
After surgery, the patient's retina was reattached, and her vision was partially restored. (bvsalud.org)
Field of vis1
The field of vision is that portion of space in which objects are visible at the same moment during steady fixation of gaze in one direction. (noorvision.om)
Light1
Their size allowed psychic pneuma to flow in abundance, emerging from the eyes to unite with the incoming light, a process essential for vision. (nature.com)
Removal1
In vision, ablation refers to the surgical removal of eye tissue to correct a refractive error such as myopia. (retinalaser.com)
Characteristics1
Demographic characteristics, ocular findings, best corrected visual acuity, and sweep visual evoked potential results were recorded. (aboonline.org.br)
Myopia2
In vision, ablation refers to the surgical removal of eye tissue to correct a refractive error such as myopia. (appelmaneye.com)
In an 18 month infant, ectopia lentis, cataract, and myopia with poor vision were noted. (arizona.edu)
Visual2
For example, if your visual acuity is 20/100 that means that the line you correctly read at 20 feet could be read by a person with normal vision at 100 feet. (appelmaneye.com)
Symptoms include eyestrain associated with near work (such as reading or using a computer), periodic blurring of distance vision especially following sustained near visual work, tendency to hold near work closer than expected, headaches with near work, and possible double vision. (appelmaneye.com)
Disease2
In an earlier study, the eyes of participants with the degenerative vision disease Macular Telangiectasia Type 2 (MacTel) who got the implant seemed to do better as compared to those who did not. (nih.gov)
Reports of ocular disease before modern genotyping are not specific to the subtypes of CDG I now recognized. (arizona.edu)
Type1
If only one camera setup is to be used for all external ocular photographic assignments, then one with a point source type of electronic flash is more universally applicable. (medscape.com)
