Depth of Suppression in Adults with Amblyopia Post Anti-Suppression Therapy

Amblyopia is a developmental visual disorder resulting from abnormal visual experience during early life and is characterized by reduced best-corrected visual acuity in one or, less commonly, both eyes in the absence of identifiable structural abnormalities. This study evaluated changes in depth of suppression in adults with amblyopia following a structured program of office-based anti-suppression therapy. Participants underwent ten in-office sessions, and high-contrast crowded visual acuity along with depth of suppression were measured using Bagolini striated glasses with neutral density filters before and after therapy. Results demonstrated a significant reduction in depth of suppression accompanied by improved visual acuity, indicating that anti-suppression therapy effectively enhances binocular visual function in adult amblyopes.
