Aim: To report the clinical profile of non-strabismic binocular vision anomalies(NSBVA) in patients with asthenopia in North-East India. Materials and methods: A hospital based study was conducted on 131 patients from age group 10-40 years attending the vision therapy clinic. Patients were divided into age groups of 13-20 years, 21-30 years and 31-40 years. A detailed orthoptic evaluation was carried out including sensory and motor testing and a diagnosis was made comparing various orthoptic parameters of the patients. Results : Of the 131 patients, 81 were female and 50 were male. The number of patients was 62 in 10-20 year age group, 49 in 21-30 year age group and 20 in 31-40 year age group. The prevalence of NSBVA in age group 10-20 year was 69.35%, 21-30 years was 67.35% and 31-40 year was 50%. The most common NSBVA was convergence excess. Conclusion: early dtection of NSBVA is important because these deviations may decompensate without treatment and become strabimic.
