白内障眼的术前黄斑功能估价,对预测术后视力是重要的。用视力性质分析法对白内障眼黄斑功能估价,方法简单,特异性高。方法是遮盖一眼,嘱其用患眼固视眼前50cm 处手电简光源,观察角膜映光点位置。在角膜中央者为中心固视;偏离角膜中央者为中心外固视。木文对16例18只眼白内障(后天性)住院病人术前用角膜映光点检查,术后眼底黄斑机能、视力情况进行分析。临床资料与结果病人为1985.1月—1987.12月在我院住院手术的16例18眼自内障患者。男9例11眼,女7例7眼。年龄在34岁至71岁,平均58岁。老年性白内障15跟,外伤性白内障3
The evaluation of preoperative macular function in cataract eyes is important for predicting postoperative visual acuity. Visual acuity analysis of cataract macular function evaluation, the method is simple, high specificity. The method is to cover one eye, and instruct the use of eyesight 50cm at the front flashlight light source, observe the corneal reflection point position. Center in the cornea for fixation; deviated from the center of the cornea for external fixation. In 16 cases of cataract (acquired) inpatient, 16 cases were examined by corneal reflectance before operation, and their macular function and visual acuity were analyzed. Clinical data and results of patients from January 1985 to December 1987 hospitalized in our hospital in 18 cases 18 cases of cataract patients. 9 males and 11 females, 7 females and 7 eyes. The age of 34 to 71 years old, with an average of 58 years old. 15 with cataract, traumatic cataract 3
