Evaluation of strabismus in 0-18 years of age group in tertiary health care hospital: A prospective cross-sectional observational study

Abstract

The main objective of the study was to study the pattern of strabismus, determine the type of refractive error and measure the angle of deviation, determine streoacuity by WFDT in 0-18 years of age group. This was a prospective cross-sectional observational study. Total 50 patients were taken. Patients of 0-18 years of age presenting with squint included in study. Patients were evaluated for VA, both distance and near vision without glasses as well as BCVA tested. Anterior segment evaluation using slit lamp, cycloplegic refraction using atropine (0-9 years) or cyclopentolate (10-18 years), fundus examination, PBCT, WFDT test done. In study, total 50 subjects of 0-18 years of age group was taken. In them boys were more than girls. 49(98%) had comitant strabismus and 1(2%) had incomitant strabismus. 32(64%) had esotropia and 18(36%) had exotropia. Among esotropia 11(34.37%) had accommodative esotropia, 13(40.62%) had partially accommodative, 7(21.87%) had non accommodative, 1(3.12%) had restrictive esotropia. Among exotropia 9(50%) had basic exotropia, 6(33.33%) had divergence excess and 3(16.66%) had convergence insufficiency. 14(28%) had amblyopia. 32(64%) had hypermetropia and 18(36%) had Myopia. 33(64%) had central fixation and 12(24%) had eccentric fixation. In binocularity, 6(12%) had ARC, 25(50%) had unilateral suppression, 10(20%) had alternate suppression.Comitant squint was more common than incomitant squint. Among comitant squint, esotropia was more common than exotropia.
