Призматический этап лечения пациентов при остро приобретенной эзотропии с диплопией

Abstract

Purpose. To analyze changes in binocular vision functions in patients with acutely acquired esotropia after preoperative correction by prisms. Material and methods. The study included 10 patients with acutely acquired esotropia with diplopia. Depending on the tactics of preoperative case management, two groups were distinguished: 1 - 5 patients, this group underwent preoperative prismatic correction of diplopia and the deviation angle, 2 - 5 patients, in this group underwent surgery without prior prismatic correction. Fresnel prisms were used to select and assign prismatic correction. The patients were monitored dynamically. Results. In the course of treatment 1 group according to the indicator of Worth's four-dot test color test, revealed a statistically significant increase in the frequency of value of the binocular single vision (p=0.041), the frequency of the presence of stereovision according to the Fly-test (p=0.013). Conclusion. Prismatic correction in combination with surgical treatment had better curative benefits than surgery itself in improving binocular and stereoscopic visual functions. Key words: acutely acquired esotropia, binocular vision, Fresnel prisms.
