Aim: This study aims to evaluate the contrast sensitivity, color vision, and stereoacuity in amblyopic eyes.
Materials and Methods: A prospective, cross-sectional, hospital-based study includes 64 amblyopic patients (79 eyes), with age between 10 and 30 years, which represents the study sample. Thirty-six normal individuals of same age group were taken as a control group. The history of the patients was taken; vision, objective, and subjective refraction were performed. Pinhole was used to determine the amblyopia. Color vision, contrast sensitivity, and stereoacuity tests were done for both groups.
Results: Anisometropic amblyopia represents 51.5% of cases. Significant decrease in contrast sensitivity was detected compared with the control group (P = 0.000). Color vision defect was found in 39.2% of amblyopic patients; 27.8% were tritanopes. Amblyopia affected stereoscopic vision in 48.5% of patients with mean 43.44 ± 95.17.
Conclusion: Early detection of causes of amblyopia may prevent the bad Consequences.
