视盘形态分析在基层医院原发性开角型青光眼早期诊断中的作用

Value of optic disc formation analysis in early diagnosis of primary open angle glaucoma in basic hospital

目的：探讨视盘形态分析在原发性开角型青光眼早期诊断中的作用。方法：选取72例视乳头杯盘比在0.5~0.8之间的受检者进行视力、裂隙灯、直接检眼镜检查、测眼压及24h眼压曲线、检影验光，并行房角镜、电脑视野和光学相干断层成像（optical coherence tomography,OCT）检查，并对上述检查结果进行分析。结果：视盘形态正常者仅有10例眼压在可疑范围，视野、OCT检查未见异常；而视盘形态异常者中眼压、视野及OCT异常者占较大比例。结论：视盘形态在原发性开角型青光眼早期诊断中是一敏感因素。

AIM： To investigate the value of optic disc formation analysis in early diagnosis of primary open angle glaucoma. METHODS： Seventy-two examinees whose cup-disc ratio were 0.5-0.8 underwent ophthalmic routine examina-tions, gonioscopy, perimetry and optical coherence tomography（OCT）, and the results were analyzed. RESULTS： The intraocular pressure of only 10 exami-nees with normal optic disc formation fell on the “suspicious” range. All the examinees with normal optic disc formation got normal results in perimetry and OCT. A big proportion of examinees with abnormal optic disc formation got abnormal results in intraocular pressure measurement, perimetry and OCT. CONCLUSION： The optic disc formation is a sensitive factor in early diagnosis of primary open angle glaucoma. 
