一、前言: 虹膜新生血管通常称为虹膜红变(Rubeosis iridis)。它常合并有继发性青光眼,而且常因此而摘除眼球。新生血管可单独存在于虹膜,且很细微有时难于辨认。此新生血管亦可累及房角,亦可伴有或不伴有眼内压升高。有些虹膜新生血管可自发消失,但有些可导致失明。虹膜新生血管可合并或继发于某些全身性或眼部疾患,最常见的是糖尿病性视网膜病变及视网膜中央静脉阻塞对增殖性糖尿病性视网膜病变引起的并发 I. INTRODUCTION: The iris neovascularization is commonly referred to as Rubeosis iridis. It is often associated with secondary glaucoma, and often remove the eye. Neovascularization can exist alone in the iris, and very subtle sometimes difficult to identify. This neovascularization can also affect the angle of the anterior chamber, with or without elevated intraocular pressure. Some iris neovascularization can disappear spontaneously, but some can lead to blindness. Iris neovascularization may be associated with or secondary to certain systemic or ocular conditions, most commonly diabetic nephropathy and central retinal vein occlusion to proliferative diabetic retinopathy
