Abstract

Purpose: To know the reliability of monocular estimation method and objective convergence measurement as an alternative protocol for screening nonstrabismic binocular vision anomalies.

Design: a cross-sectional descriptive observational prospective study.

Methods and Materials: 40 subjects; 26 females and 14 males; mean age (20.31 ± 1.92) were evaluated for accommodative facility and accommodative status with the help of monocular estimation method (dynamic retinoscopy). Objective near point of convergence was assessed with red filter and penlight target. All the tests were done with best corrected visual acuity after refractive error correction. Further these findings were correlated with routine orthoptic work up to know whether these tests alone can be an alternate screening method of nonstrabismic binocular vision anomalies or not.

Results: 27.5% of the subjects were found to have Non Strabismic binocular vision anomalies in relation to conventional routine orthoptic work up showed 32.5% of prevalence. A strong level of agreement (kappa value 0.88) was found, showed statistical significant p < 0.001.

Conclusions: Objective assessment of accommodative facility, status of accommodation and near point of convergence can be alternative protocol for screening nonstrabismic binocular vision anomalies in community set up.
