Abstract
A developmental disorder of spatial vision, Amblyopia is defined clinically as a decrease in visual acuity (VA) in one, or more often in both eyes, in the absence of a clear disorder or ocular disease Amblyopia is the most common cause of monocular vision loss in children [1]. Affected individuals exhibit stereo acuity impairment and abnormal binocular summation [2]. Binocular therapies designed to improve amblyopia by binocular stimulation are highly differentiated into perceptual learning and differential training. Objective • To determine the efficacy of Vision Therapy software (CureSee) in Amblyopia. • To compare Stereopsis findings before and after VT • To compare Visual Acuity before and after VT • To compare Vergence amplitude before and after VT. Methodology: 68 Amblyopic Subjects who are visiting Ahooja Eye & Dental Institute, Gurugram for eye examination and Amblyopia management were taken. Patients diagnosed with Amblyopia were included as well as Patients with Ocular surgery done within 2 months and Patients with any Ocular pathology were excluded. Verbal Consent was taken and selected patients were enrolled into CureSee Vision Therapy Software management for Amblyopia. Data is collected prior and post the use of CureSee Vision Therapy Software by patients and the collected data were decoded and tabulated using the Ms. Excel 2010 computer program and IBM Statistical Package for Social Sciences (SPSS) statistics version 23.0 was used for the analysis of data. Result and Conclusion: Visual Acuity improved significantly by 0.14 LogMar to the Median Values of Right Eye and by 0.60 LogMar to the Median Values of Left Eye. Stereopsis improved from 800 ± 520 sec of arc to 60 ± 60 sec of arc with P≤0.001. PFV and NFV also improved significantly after the use of Vision Therapy Software. Results conclude that Vision Therapy software is effective in improving Stereopsis, Visual Acuity and Vergence values in Amblyopic patients.
