摘要
目的:应用视觉对比敏感度的视功能检查方法,检查原发性急性闭角型青光眼(PACG)患者急性发作期眼压控制后患眼的视网膜对比敏感度,与正常眼作对比,验证其是否存在差异,并探讨青光眼急性发作期患者视网膜对比敏感度的空间频率特点。方法:选择PACG急性发作期眼压控制后患眼36例(48只眼),正常对照24例(48只眼),应用RM-800视觉检查仪进行视网膜对比敏感度检查,经SPSS进行组间对照t检验。结果:视网膜对比敏感度在PACG急性发作期眼压控制后患眼与正常对照组的对比在12周/度,18周/度及24周/度均具有统计学意义,P<0.02。结论:PACG患者急性发作期眼压控制后患眼的视网膜对比敏感度较正常对照组差异有统计学意义,其主要表现为高频段空间对比敏感度损害。
Objective:To observe the changes in contrast sensitivity(CS) in patients with primary acute angle-closure glaucoma(PACG).Methods:CS was performed in 36 patients(48eyes) with acute attack stage of PACG and 204 normal subjects(48eyes).Results:The results of CS tests were abnormal in PACG patients when they were compared with those of normal people.The threshold of CS at 12.0 c/d,18.0 c/d and 24.0 c/d were increased(P<0.02).Conclusion:CS is sensitive parameters for visual function evaluating of acute attack stage of PACG.
