Clinical Outcomes of Implantationof Black Diaphragm Intraocular Lens in Complete Aniridia and Aphakia Due to Posttraumatic Eye Rupture

Purpose: To assess long-term outcomes of implantation of black diaphragmintraocular lens (BD IOL) in postraumatic aniridia and aphakia due to eye rupture. METHODS: This is retrospective c...

A Multi Focal Visual Outcome Study Using Different Near Additions

A multi-centre non-randomized clinical investigation to assess multifocal visual outcomes using different near additions, for the treatment of aphakia after cataract removal.

Nurses Ability to Assess Visual Acuity in Geriatric Consultation

Nurses participate to geriatric evaluations for falling patients. For these patients, it is recommended to evaluate,especially, visual acuity but this is not currently done because it is d...

Evaluation of VisionQuest 20/20, a Visual Acuity Testing Software

This study involves the use of VisionQuest 20/20 which is a new software program to test visual acuity in children. The purpose of this study is to compare the results of VisionQuest 20/2...

Correlation of monocular grating acuity at age 12 months with recognition acuity at age 4.5 years: findings from the Infant Aphakia Treatment Study.

To determine whether grating acuity at age 12 months can be used to predict recognition acuity at age 4.5 years in children treated for unilateral congenital cataract enrolled in the Infant Aphakia Tr...

Amblyopia: The Thalamus Is a No-Go Area for Visual Acuity.

When one eye does not function well during development, the visual cortex becomes less responsive to it and visual acuity declines. New research suggests that reduced response strength and deteriorati...

Five year postoperative outcomes of Bilateral Aphakia and Pseudophakia in children upto 2 years of age: a Randomized Clinical Trial.

Comparative evaluation of complications and visual outcomes following bilateral congenital cataract surgery in children upto 2 years of age with and without primary intraocular lens (IOL) implantation...

Possible Influencing Factors for the Prediction of Postoperative Visual Acuity Gain after Retroiridal Iris Claw Lens Implantation.

To determine effect sizes for visual acuity (VA) and visual acuity gain (ΔVA, pre- to postoperative) after the implantation of retroiridal Verisyse iris-claw lenses.

Near visual acuity of dental hygienists with and without magnification.

The aim of this study was (i) to evaluate the visual performance of dental hygienists in their clinical environment and (ii) to analyse the relationship between self-assessed and objectively measured ...

Medical and Biotech [MESH] Definitions

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.

Visual impairments limiting one or more of the basic functions of the eye: visual acuity, dark adaptation, color vision, or peripheral vision. These may result from EYE DISEASES; OPTIC NERVE DISEASES; VISUAL PATHWAY diseases; OCCIPITAL LOBE diseases; OCULAR MOTILITY DISORDERS; and other conditions. Visual disability refers to inability of the individual to perform specific visual tasks, such as reading, writing, orientation, or traveling unaided. (From Newell, Ophthalmology: Principles and Concepts, 7th ed, p132)

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.

Absence of crystalline lens totally or partially from field of vision, from any cause except after cataract extraction. Aphakia is mainly congenital or as result of LENS DISLOCATION AND SUBLUXATION.

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.
