Abstract

Purpose: To evaluate major symptoms and non strabismic binocular vision disorders among VDU users in Bangalore.

Methodology: Among 90 VDU users, assessment included visual acuity, retinoscopy, convergence, accommodation, fusional vergence, vergence facility and accommodation facility. Subjects’ symptoms were recorded in the COVD questionnaire (QOL 19).

Results: Mean age of subjects was 25.8 ± 3 years. Ocular changes were reported in 85% of the total subjects. The common non strabismic binocular vision anomaly was Convergence insufficiency with a secondary accommodative excess. The most common symptoms (p < 0.001) were headache with near work and trouble keeping attention on reading.

Conclusion: Convergence insufficiency associated with a secondary accommodative excess and headache with near work were the most common abnormalities and symptom reported. Non strabismic binocular vision disorders were correlated with symptoms assessed through COVD questionnaire (QOL 19).
