Purpose: Previously, we have mapped amblyopic eye suppression within the central 20° of the visual field and observed a gradient of suppression that is strongest in central vision and weakens with increasing eccentricity. In this study, using a large dichoptic display, we extend our novel suppression mapping approach further into the periphery (from 20°-60°) to assess whether suppression continues to decline with eccentricity or plateaus. Methods: Sixteen participants with amblyopia (10 with strabismus, 6 with anisometropia without strabismus; mean age: 37...

PURPOSE: To determine the long-term visual outcomes and risk factors for visual loss in children with primary congenital glaucoma (PCG) who underwent angle surgery over a 21-year period. METHODS: This was a retrospective study of patients who underwent trabeculotomy, trabeculectomy, or combined trabeculotomy-trabeculectomy for PCG. Visual acuity (VA), surgeries, and underlying cause of visual impairment were recorded and compared. Main outcome measures were final best-corrected good VA (20/20 to 20/50), moderate VA (<20/50 to 20/200), or poor VA (<20/200); age at surgery, sex, laterality, type of initial glaucoma surgery, and number of surgeries were recorded...

Importance: Uncorrected refractive errors are the most common cause of visual impairment in children despite correction being highly cost-effective. Objective: To determine whether less expensive ready-made spectacles produce rates of spectacle wear at 3 to 4 months comparable to those of more expensive custom-made spectacles among eligible school-aged children. Design, Setting, and Participants: This noninferiority, double-masked, randomized clinical trial recruited children aged 11 to 15 years from January 12 through July 31, 2015, from government schools in urban and periurban areas surrounding Bangalore, India...

The theme of the 2016 Burian Lecture is how our understanding of strabismus has been changed by the research carried out in our laboratory in Reading over the years. Accommodation and convergence are fundamental to orthoptics, but actual responses have often been very different compared to what we had expected. This paper outlines how our laboratory's understanding of common issues such as normal development of accommodation and convergence, their linkage, intermittent strabismus, anisometropia, orthoptic exercises, and risk factors for strabismus have changed...

We investigated the potential causal relationships between anisometropia, amblyopia and strabismus, specifically to determine whether either amblyopia or strabismus interfered with emmetropization. We analyzed data from non-human primates that were relevant to the co-existence of anisometropia, amblyopia and strabismus in children. We relied on interocular comparisons of spatial vision and refractive development in animals reared with 1) monocular form deprivation; 2) anisometropia optically imposed by either contact lenses or spectacle lenses; 3) organic amblyopia produced by laser ablation of the fovea; and 4) strabismus that was either optically imposed with prisms or produced by either surgical or pharmacological manipulation of the extraocular muscles...
