We describe early features of choroidal neovascularization in 50 pathologically myopic eyes. The eyes were classified into three categories on the basis of degree of myopic chorioretinal degeneration in the posterior pole: mild diffuse atrophy, severe diffuse atrophy and focal atrophy. Choroidal neovascular membranes (CNMs) were grouped into a minimally leaking type and a markedly leaking type in fluorescein angiographic patterns. CNMs were more frequently associated with the mild diffuse atrophy than with the other atrophies. Of the markedly leaking CNMs, 83% were seen in eyes with mild myopic chorioretinal degeneration and 78.5% of the minimal leaking CNMs were found in eyes with severe myopic chorioretinal degeneration. In association with CNMs, lacquer crack and the granular hypofluorescein lesions were observed in 72% and 40%, respectively. The visual acuity deteriorated in all of the 14 eyes which could be followed up more than 1 year.
我们描述了50只病理性近视眼中脉络膜新生血管的早期特征。根据后极部近视性脉络膜视网膜变性的程度，将这些眼睛分为三类：轻度弥漫性萎缩、重度弥漫性萎缩和局灶性萎缩。根据荧光素血管造影模式，脉络膜新生血管膜（CNM）分为微渗漏型和明显渗漏型。与其他萎缩类型相比，CNM更常与轻度弥漫性萎缩相关。在明显渗漏的CNM中，83%见于轻度近视性脉络膜视网膜变性的眼睛，78.5%的微渗漏CNM见于重度近视性脉络膜视网膜变性的眼睛。与CNM相关的漆裂纹和颗粒状低荧光病变分别在72%和40%的眼中观察到。在14只能够随访超过1年的眼睛中，视力均下降。
