The effects of classification on stereoacuity in patients with intermittent exotropia
摘要
Abstract
Objective To evaluate and compare stereoacuity with respect to classification in intermittent ex-otropia(IXT).Methods 224 patients with IXT undergoing strabismus surgeries in Beijing Tongren Hospital were involved. All patients were divided into three groups according to near and distant deviation: convergence insufficiency (78 cases), basic (131cases) and divergence excess (15 cases). The stereoacuity at distance and near were compared among the three groups. Furthermore patients were divided into four groups according to preoperative refractive error: hyperopia, emmetropia,myopia, anisometropia. The effects of refractive error on the classification of IXT were analyzed.Results (1) The ratio of having distance stereoacuity in IXT with convengence insufficiency, basic and divergence excess were 24.4%、15.3% and 33.3%. There was no significant difference in distance stereoacuity among the three groups. The ratio of having near stereoacuity in IXT convengence insufficiency, basic and divergence excess were 87.2% 、 67.9% and 93.3% . There was significant difference in near stereoacuity among the three groups (P =0.002). The near stereoacuity was best reserved in IXT with divergence excess. (2)there was no correlation between refractive errors and IXT type. Conclusion For the IXT patients, IXT type has little effect on distance stereoacuity, however it affected the near stereoacuity. The near stereoacuity was best reserved in IXT with divergence excess. The influence of IXT type on the near stereoacuity is independent of refractive errors.关键词
