Background: Convergence Insufficiency is characterized by a decreased ability to converge the eyes and maintain binocular fusion while focusing on a near target. The most common treatment for convergence insufficiency is orthoptic exercises.

Aim: Aim of this study was to assess and compare the effect of orthoptic exercises with dietary supplements for the relief of asthenopic symptoms in patients with convergence insufficiency.

Methodology: This Quasi Experimental study was conducted in THQ Karor Lal Eason, District Layyah on the patients presenting with convergence insufficiency caused by muscle imbalance. Total 90 patients were randomly divided into 3 groups of 30 patients each, by non-Probability purposive sampling technique. The study duration was September 2022 to May 2023. Patients have the 18.5- 24.5 BMI range were included. Orthoptic exercise (brock string test), dietary supplement (vitamin C) and combination of both were prescribed to group 1, 2 and group 3 respectively. Follow ups were performed on 2nd and 4th week of the study. Data was analyzed using IBM SPSS. Descriptive statistics and one way ANOVA were applied.

Results: The mean values of RAF measurements at baseline were 14.7±0.9, 14.9±0.9 and 15.7±1.41 in group 1, 2 and 3, respectively. The mean values of RAF measurements at first follow up were 12.4±0.4, 14.0±0.9 and 11.2±0.8 of group 1, 2 and 3 respectively. The mean values of RAF measurements at 2nd follow up were 10.0±0.0, 142.6±0.6 and 6.8±0.7 in group 1, 2 and 3 respectively. The results showed significance results which were p=0.00 at the 1st and 2nd follow up.

Conclusion: It was concluded that orthoptic exercise and combination of orthoptic exercise and dietary supplements is a best treatment options for the relieving of asthenopic symptoms in patients with convergence insufficiency as compared to dietary supplements only.
