青光眼早期诊断至关重要,视盘形态学改变是青光眼早期征象,可出现在视野缺损之前。正常人视盘参数有变异且有种族差异。青光眼视盘改变主要表现有视网膜神经纤维层厚度变薄、盘沿面积的缩小和视杯形态的改变等。海德堡视网膜断层扫描仪检查具有高分辨率,能客观、无创伤地获得视盘三维图像,并可定量分析和随访青光眼视盘改变。现介绍其原理及在青光眼早期诊断和随访中的应用。 Early diagnosis of glaucoma is crucial, optic disc morphology is an early sign of glaucoma, can appear in the field of vision before the defect. Normal disc parameters have variations and racial differences. Glaucomatous optic disc changes in the main manifestations of retinal nerve fiber layer thickness thinning, along the reduction of disk area and optic disc morphology changes. Heidelberg retina scanner with high resolution, objective, noninvasive access to three-dimensional disc images, and quantitative analysis and follow-up glaucoma optic disc changes. Now introduce its principle and its application in the early diagnosis and follow-up of glaucoma.
