INFLUENCE CYCLOPLEGICS FUNDS FOR THE DEVIATION ANGLE IN PATIENTS WITH ESOTROPIA

Abstract

Objective: to evaluate the manifestations of increased esodeviation under cycloplegia in children with hyperopia and esotropia. Materials and methods. 27 children aged 3 to 8 years with a friendly convergentstrabismus and hypermetropicrefraction were taken to be studied. Ophthalmic examination included visometry, retinoscopy before and after cycloplegia, determination of the angle of deviation before and after cycloplegia. To cause the cycloplegia all patients went through instillation of 1% cyclopentolate, 0.5-1% tropicamide or mydrimax 3 times in a row with a five-minute interval. Results. 15 patients (55.6%) had accommodative strabismus, 7 (25.9%) - partially-accommodative strabismus, 5 (18.5%) had non-accommodative strabismus. Seven patients were diagnosed with amblyopia (25.9%). The average index of the manifest refractive was Hm 2.43 D, and the cycloplegic refraction was Hm 3.75 D. The angle of esodeviation before cycloplegia in average was 10 degrees at a long distance and 10 deg. at a close distance. The average angle of deviation after cycloplegia was 15 deg. at a long distance and 20 deg. at a close distance. After cycloplegia eleven patients (40.1%) had an increase of esodevisation, including 7 patients with accommodation and 4 patients with non- accommodation strabismus. Conclusion. Children with accommodative esotropia and hypermetropic refraction often have an elevated angle of deflection after using short-acting cycloplegics. Сycloplegics can cause a different influence on the esodeviation, and the increased angle of esodeviation can be assumed to help to reveal the hidden deviation in some patients with hypermetropia and esotropia (bibliography: 8 refs).
