白内障眼晶体混浊达到一定程度时需手术治疗,在窥不见眼底情况下,手术前如何判定其视功能历来是眼科学上的一个难题。以往主要通过检查光觉、色觉可大致估计视网膜和视神经的情况,但这些方法均不能准确判定黄斑部机能。夏氏首次应用角膜映光法检查后天性白内障的固视性质,初步认为固视性质检查对其预后估计有实用价值;其后,刘氏、邱氏、周氏也有这方面的报道。本文应用角膜映光法检查后天性白内障34眼的固视性质,并对术后眼底所见、黄斑机能和视力情况进行分析,现将结果报告于下: 资料与方法 Cesarean eye crystal turbidity to a certain extent, the need for surgical treatment, in the case of peeping, how to determine the visual function before surgery has always been a problem in ophthalmology. In the past mainly through the inspection of light, color vision can be roughly estimated retina and optic nerve, but these methods can not accurately determine the macular function. For the first time, Hirschsprung’s method was used to examine the fixation property of posterior cataract, which was initially believed to have practical value in estimating the prognosis. Later, Liu, Chiu and Zhou also reported this. In this paper, corneal photopic examination of posterior cataract 34 eyes of the fixation nature, and postoperative fundus, macular function and visual acuity were analyzed, the results are reported below: Materials and Methods
