本研究目的是采用不同波长的激光,对正常色觉的患者进行局限的黄斑外光凝引起的颜色对比敏感度(CCS)急性改变作比较。方法:选择患有急性后玻璃体脱离伴有视网膜下液,视网膜马蹄形裂孔小于1个视盘直径的患者,作预防性激光光凝。并对有单纯裂孔的患者征得同意后加入本项研究。有过其它
The purpose of this study was to compare the acute change in color contrast sensitivity (CCS) caused by localized macular photocoagulation in patients with normal color vision using lasers of different wavelengths. Methods: Preventive laser photocoagulation was selected in patients with acute posterior vitreous detachment associated with subretinal fluid and retinal horseshide hole less than one disc diameter. Patients with a simple hole and agreed to join the study. There are other
