Early diagnosis of congenital glaucoma allows surgery to be performed at the stage of reversible glaucomatous alterations of the optic disc and retina. In primary congenital glaucoma, the main reason for visual acuity reduction following surgical stabilization of the intraocular pressure are corneal changes. These include an increased corneal diameter, Haab's striae, areas of thickening and a greater posterior elevation. The resultant irregular astigmatism leads to amblyopia and a marked decrease in visual acuity...

PURPOSE: To evaluate the role of monocular video game play as an adjuvant to occlusion therapy in the treatment of anisometropic amblyopia. METHODS: In a prospective randomized study design, 68 children with ages ranging from 6 to 14 years who had anisometropic amblyopia with a best corrected visual acuity (BCVA) in the amblyopic eye of better than 6/36 and worse than 6/12 and no manifest strabismus were recruited. They were randomly allocated into two groups: 34 children received 1 hour per day of video game play for the first month plus 6 hours per day of occlusion therapy (video game and occlusion group) and 34 children received 6 hours per day of occlusion therapy alone (occlusion only group)...

Previous studies have observed functional deficits in primary visual cortex. With the development of functional magnetic resonance imaging and electrophysiological technique, the research of the striate, extra-striate cortex and higher-order cortical deficit underlying amblyopia reaches a new stage. The neural mechanisms of amblyopia show that anomalous responses exist throughout the visual processing hierarchy, including the functional and structural abnormalities. This review aims to summarize the current knowledge about structural and functional deficits of brain regions associated with amblyopia...

PURPOSE: Previous studies of the relationship between visual acuity (VA) and ocular dominance have produced conflicting results. We hypothesized that (1) the discrepancies were related mostly to sample size and interocular visual acuity difference (IOVAD); (2) in large samples of individuals with marked IOVADs, the eye with the better uncorrected distance visual acuity (UDVA) would be dominant. These hypotheses were tested in a large group of myopic patients. METHODS: This prospective study of cycloplegic refraction involved 2045 myopic refractive surgery candidates...

BACKGROUND: Peters anomaly normally presents in early childhood. Common features are central corneal opacities and dysgeneses of the anterior eye segment. Early surgery is commonly warranted to prevent deep amblyopia or because of severe glaucoma. We herein present the clinical outcomes of all patients treated in the Eye Center of the Albert Ludwigs University of Freiburg since 2005. Emphasis is placed on the Peters subtype. METHODS: Data were collected retrospectively by means of chart review...

Strabismic amblyopia is now acknowledged to be more than a simple loss of acuity and to involve alterations in visually driven attention, though whether this applies to both stimulus-driven and goal-directed attention has not been explored. Hence we investigated monocular threshold performance during a motion salience-driven attention task involving detection of a coherent dot motion target in one of four quadrants in adult controls and those with strabismic amblyopia. Psychophysical motion thresholds were impaired for the strabismic amblyopic eye, requiring longer inspection time and consequently slower target speed for detection compared to the fellow eye or control eyes...

PURPOSE: Binocular summation (BiS) occurs when binocular visual function surpasses that of the better eye alone. We sought to evaluate whether strabismic amblyopia reduces BiS more than strabismus alone, and determine whether BiS improves in strabismic amblyopes after strabismus surgery. METHODS: We prospectively recruited 15 patients with strabismic amblyopia who then underwent strabismus surgery. Thirty age-matched normal subjects and 30 non-amblyopic strabismic patients served as controls...

BACKGROUND: Reliable detection of central fixation and eye alignment is essential in the diagnosis of amblyopia ("lazy eye"), which can lead to blindness. Our lab has developed and reported earlier a pediatric vision screener that performs scanning of the retina around the fovea and analyzes changes in the polarization state of light as the scan progresses. Depending on the direction of gaze and the instrument design, the screener produces several signal frequencies that can be utilized in the detection of central fixation...

Strabismus is one of the most challenging subspecialties encountered in the field of ophthalmology. The concept of etiology of strabismus is being advanced with the development of newer imaging modalities and increased understanding of the genetics of strabismus. Imaging is also being used to aid in the planning of strabismus surgery. Newer horizons are being explored in the amblyopia management. The good old eye-pad is being replaced with the iPad. Early detection of loss of stereopsis is being used to decide the timing for strabismus surgery...
