青光眼的诊断主要依靠眼压、视野、视神经盘形态的变异来判断,眼压和视野已有较精确的测定方法,而对视神经盘的变异尚未能充分认识,60年代人们才开始对视盘进行研究,对老年人视盘的变异国内尚未见报导。在开角型青光眼,早期视盘凹陷的变异常比视野缺损出现得早,甚至眼压尚无持续性升高时已有视盘形态的变化,故眼底检查可更早发现青光眼的线索。 Glaucoma diagnosis mainly depends on intraocular pressure, visual field, optic disc morphology variation to determine intraocular pressure and field of vision have been more accurate determination of the optic disc has not been fully aware of the variation in the 60s people began to treat the optic disc Research, the elderly have not seen the report of domestic variability of optic disc. In open-angle glaucoma, early disc degeneration often than visual field defects appear earlier, and even when the intraocular pressure has not been increased continuously when the disc morphology has been changed, so the fundus examination can be found earlier clues to glaucoma.
