Влияние диагностики первичной гиперфункции косых мышц на выбор метода хирургического лечения

Abstract

Purpose. To carry out a comparative analysis of the results of strabismological examination of patients with primary inferior oblique muscle overaction using the generally accepted and proposed methods. Methods. The research included 123 patients with bilateral symmetric primary inferior oblique muscle overaction. The proposed method consisted in measuring hypertropia magnitude of the adducted eye with the maximum fixing movement of the abducted eye gaze and in measuring heterotropia magnitude with the maximum gaze movement upwards and downwards. Results. As a result of diagnostics according to the generally accepted and proposed method, a statistically significant increase in hypertropia and V-syndrome (р < 0.05) was revealed. A more pronounced degree of hypertropia was detected in 110 patients (89.43 %), more pronounced manifestations of the V-syndrome in 117 patients (95.12 %). In 83 patients (67.48 %), the tactics of surgical treatment was optimized. Conclusions. The average underdiagnosis of hypertropia and V-pattern during the examination according to the generally accepted method is 3.98±2.39° and 3.72±2°, respectively. Key words: primary inferior oblique muscle overaction; V-pattern; Botox; partial marginal myotomy; myectomy.
