摘要
运用Nicolet CS—2000对比敏感度检测仪,对78例(96眼)早期老年性黄斑变性(SMD)和103眼正常组进行了对比敏感度(CSF)测定,所有的病人眼底均有玻璃膜疣(drusen),视力或矫正视力≥1.0.采用静态正弦对比阈值频率从0.5～22.8周/度。结果显示视力正常的SMD 的CSF 也有异常,并与drusen的数量、部位及融合程度有关,提示CSF 在检查早期SMD 的视功能改变是较为有效的方法。
In this study,the contrast sensitivity(CSF)ranging from 0.5 to 22.8 cycles/degree(c/d)was obtained from 78 cases(96 eyes)with early senile macular degeneration(SMD)and 103 normal eyes.All the patients who had best corrected visual acuity of 1.0 or bet-ter were found drusen in fundus.The results showed that the CSF could be abnormal inSMD patients with normal vision acuity,the loss of CSF correlated with numbers,locationand confluent of drusen.The author suggested that the CSF is more effective method forearly diagnosis of SMD.
