摘要:

目的 探讨棱镜矫治急性共同性内斜视引起复视的棱镜处方量。设计 回顾性病例系列。研究对象 急性共同性内斜视所引起复视并进行棱镜矫正患者42例。方法 对急性共同性内斜视引起复视的患者分别予以马氏杆、同视机、Von Graefe棱镜分离、三棱镜加交替遮盖法行斜视度检查;同时行聚散力测量;给患者试戴棱镜,以达到复视消除、无不适效果的处方量作为棱镜最终处方量。分析各测量结果与处方量之间的相关性。主要指标 斜视度。结果 马氏杆测量患者平均斜视度(20.57±9.53)△;同视机测量(16.01±8.30)△;Von Graefe棱镜分离(15.95±7.07)△;三棱镜加交替遮盖(13.24±5.01)△;破裂点(5.17±4.20)△;回归点(9.14±5.76)△。棱镜处方量(6.92±3.49)△。马氏杆检查、同视机检查、Von Graefe棱镜分离、三棱镜加交替遮盖、破裂点、回归点与棱镜处方量的pearson相关系数分别为0.496、0.546、0.647、0.408、0.831、0.708。结论 由聚散力测量眼球外转的破裂点与棱镜处方量相关性最大,可以以破裂点作为棱镜试戴的起点。(眼科, 2018, 27:146-149)

Abstract:

Objective To investigate the treatment prescription for patients with diplopia caused by acute concomitant esotropia. Design Retrospective case series. Participants Fourty-two patients with diplopia caused by acute concomitant esotropia were treated with prism. Methods Patients with acute esotropia caused by diplopia were examined with Maddox Rod,  Synoptophore,  Von Graefe prism separated by strabismus examination,  and convergence measurement. The main intention of these tests was to determine a prescription volume to achieve maximum elimination of diplopia with no discomfort. The correlation between the results retrieved from each apparatus and the amount of prescribed was analyzed. Main Outcome Measures Degree of diplopia. Results The strabismus examination showed that the Maddox Rod was (20.57±9.53) △. The results of Synoptophore indicated (16.01±8.30)△. The Von Graefe prism was(15.95±7.07)△. The fracture point was (5.17±4.20)△. Measurement by prism and cover was (13.24±5.01)△,   and the regression point was (9.14±5.76)△. Prism prescription amount was (6.92±3.49)△. The correlation coefficients of among Von Graefe prism separation,  measurement by prism and cover,  fracture point,  regression point and prism prescription amount were 0.496,  0.546,  0.647,  0.408,  0.831 and 0.708,  respectively. Conclusion The fracture point has the maximum correlation to the prescribed prism amount. It can serve as the foundation for the prism correction.(Ophthalmol CHN,  2018, 27:146-149)
