This research investigates visual function abnormalities in people with amblyopia and strabismus, conditions that affect vision clarity, contrast sensitivity, and binocular function. The study aims to measure these visual functions before, during, and after therapy to understand how treatment impacts them. The treatments being studied include glasses, patching, and atropine eye drops, along with strabismus surgery when needed. Participants will have various vision tests such as eye movement tracking, contrast sensitivity, grating and vernier acuity, visual acuity, binocular function, reading, and visual scanning evaluated. These tests will occur before therapy, during treatment, and after treatment ends. If strabismus surgery is performed, testing will continue afterward to observe changes. Throughout the study, participants will be assessed at multiple points using the visual function tests to monitor progress. The main outcomes focus on changes in visual functions over a period of up to three years, depending on treatment duration. The study is observational and follows participants from initial evaluation through the course of their therapy.
