Optic disc morphometry is a method of quantitatively evaluating the optic nerve. This study was undertaken to examine whether the optic disc morphology changes with a short-term increase in intraocular pressure. In 46 eyes with chronic open-angle glaucoma and 20 normal eyes, optic disc photographs were taken at a baseline pressure ranging between 15 and 20 mm Hg and 1 and 8 s after pressure elevation of 10 and 20 mm Hg, respectively. In the normal and glaucoma eyes the size and form of the optic disc, optic cup, and alpha and beta zones of the parapapillary chorioretinal atrophy did not change significantly with pressure elevation. We conclude that two-dimensional papillomorphometric data are not dependent on a short-term increase in intraocular pressure.
视盘形态测量是一种对视神经进行定量评估的方法。本研究旨在探讨眼内压短期升高时视盘形态是否会发生变化。对46只慢性开角型青光眼患者的眼睛和20只正常眼睛，分别在眼压基线为15至20 mmHg时以及眼压分别升高10 mmHg和20 mmHg后1秒和8秒拍摄视盘照片。在正常眼和青光眼眼中，视盘、视杯以及视乳头旁脉络膜视网膜萎缩的α和β区的大小和形态不会随着眼压升高而发生显著变化。我们得出结论，二维视乳头形态测量数据并不依赖于眼内压的短期升高。
