Eyes with pseudoexfoliation (PEX) have typical features in the morphology of the anterior segment of the eye. We carried out an investigation to ascertain whether there are also differences in the posterior segment. Using 15 degrees color stereo optic disc photographs, 55 eyes with chronic open-angle glaucoma and pseudoexfoliation and 398 eyes with primary chronic open-angle glaucoma without PEX were examined morphometrically. There were no significant differences in: (1) quantitative parameters, such as the size and form of the optic disc, optic cup, neuroretinal rim, peripapillary scleral ring Elschnig, and the alpha and beta zones of the parapapillary chorioretinal atrophy; (2) qualitative parameters such as the location of the smallest part of the neuroretinal rim, the count of bared circumlinear and cilioretinal vessels, the number and localization of optic disc hemorrhages, the discrepancy between a smaller area with pallor and a larger area with cupping, and decreased visibility of the retinal nerve-fiber bundles in the parapapillary region; (3) localized and diffuse defects in the retinal nerve fiber layer; (4) perimetric indices. Although the maximal values of the intraocular pressure were significantly higher in the PEX group, the morphology of the intra- and parapapillary region was not significantly different.
具有假性剥脱（PEX）的眼睛在前房段形态上具有典型特征。我们进行了一项调查，以确定后房段是否也存在差异。使用15度彩色立体视盘照片，对55只患有慢性开角型青光眼和假性剥脱的眼睛以及398只没有PEX的原发性慢性开角型青光眼眼睛进行了形态测量检查。在以下方面没有显著差异：（1）定量参数，如视盘、视杯、神经视网膜边缘、乳头周围巩膜环Elschnig以及乳头旁脉络膜视网膜萎缩的α和β区的大小和形态；（2）定性参数，如神经视网膜边缘最小部分的位置、裸露的环形和睫状视网膜血管的计数、视盘出血的数量和定位、苍白较小区域与杯状较大区域之间的差异以及乳头旁区域视网膜神经纤维束可见度降低；（3）视网膜神经纤维层的局部和弥漫性缺陷；（4）视野指标。尽管PEX组的眼压最大值显著更高，但眼内和乳头旁区域的形态没有显著差异。
