用Heidelberg视网膜断层扫描仪对正常人、大杯和青光眼视乳头形态结构的研究

目的：探讨正常人、大杯和原发性开角型青光眼（ｐｒｉｎａｒｙ ｏｐｅｎ ａｎｇｌｅ ｇｌａｕｃｏｍａ，ＰＯＡＧ）患者之间视乳头结构参数之间的差异。方法：用Ｈｅｉｄｅｌｂｅｒｇ视网膜断层扫描仪（Ｈｅｉｄｅｌｂｅｒｇ Ｒｅｔｉｎａ Ｔｏｍｏｇｒａｐｈ，ＨＲＴ）对正常人（２２例４４眼）、大杯（１７例３４眼）和ＰＯＡＧ患者（１９例３７眼）进行视乳头断层扫描，获得视乳头平均地形图图像和视乳头结构诸参数。结果：

Study of stereometric parameters of optic nerve head of normal, big cupped disk and glaucomatous eyes using Heidelberg Retina Tomograph

Objective:To investigate the difference of stereometric parameters of optic nerve head between normal subjects,patients with big cupped disk and primary open angle glaucoma(POAG).Methods:Twenty-two cases(44 eyes)of normal subjects,17 cases(34 eyes)of patients with big cupped disk and 19 cases (37 eyes)of patients with POAG were underwent Heidelberg Retina Tomograph (HRT)examination to get topography images and stereometric parameters of optic nerve head.Results:Besides there was no difference of disk area between big cupped disk group and POAG group,no difference of rim area,rim volume and RNFL cross secliond area thickness between normal group and big cupped disk group,statistics analysis showed that there was significant difference of other stereometric parameters between normal group and big cupped disk group or big cupped disk group and POAG group.Conclusions:There is certain difference of optic nerve head of normal subjects,big cupped disk and patients with POAG.
