青光眼可籍特征性视野缺损、视乳头凹陷及伴随的高眼压而得以确诊,然而早期确诊可能是困难的。当青光眼为非对称性者,常忽略相对瞳孔传入障碍(通常称为Gunn瞳孔)这一早期征象。Kaback等及Prywes(1976)分别注意到非对称性青光眼性视野缺损患者存在这种瞳孔异常,其中大多数患者同时有非对称性的视乳头凹陷。认为这一征象可以是高眼压性视神经损害(无视野缺损)的明确标志。就作者所知,无傍中心暗点或其它特征性青光眼视野缺损的非对称性青光眼视乳头凹陷及高眼压,而有相对瞳孔传 Glaucoma may be diagnosed with a characteristic visual field defect, optic disc depression, and accompanying ocular hypertension, however early diagnosis may be difficult. When glaucoma is asymmetric, the early signs of relative pupillary afferent disorder (often referred to as the Gunn pupil) are often overlooked. Kaback et al., And Prywes (1976) noted this pupillary abnormality in asymptomatic patients with glaucomatous visual field defects, respectively, and most of the patients had asymmetrical optic depressions. This sign is considered as a clear sign of ocular hypotensive optic nerve damage (no field defect). As far as the author knows, non-symmetrical glaucomatous ptosis and ocular hypertension in the absence of dark spots or other characteristic glaucomatous visual field defects, and relative pupil transmission
