暴发性脉络膜出血罕见,但系极严重之内眼手术并发症。似以青光眼、高血压、糖尿病及高度近视眼患者产生此并发症的机会为多。 Manschot(1955)的6例暴发性脉络膜出血眼,术前均患有青光眼。5例组织病理学检查,有一支或多支睫状动脉局部坏死,乃推断眼压升高致动脉萎陷,促进管壁变性,因而易破裂。Winslow(1974)报告一例角膜溃疡自发破裂后,发生自发性暴发性脉络膜出血,此例似为后睫状动脉进入脉络膜上腔时撕裂之故。从上述报告看,动脉循环受阻加之突然的眼压降低,似为暴发性脉络膜出血的首要因素,尤其是在青光眼。本文旨在研究脉络膜静脉回流受阻,是否为暴发性脉络膜出血的一个因素。
Fulminant choroidal hemorrhage is a rare but serious intraocular surgery complication. There are many opportunities for this complication in patients with glaucoma, high blood pressure, diabetes mellitus and high myopia. Six cases of fulminant choroidal hemorrhage were observed in Manschot (1955) with glaucoma preoperatively. 5 cases of histopathological examination, one or more ciliary artery necrosis, it is concluded that intraocular pressure caused by arterial collapse, and promote the wall degeneration, and thus easy to rupture. Winslow (1974) reported a case of spontaneous fulminant choroidal hemorrhage following a spontaneous rupture of the corneal ulcer, a phenomenon similar to what occurs when the posterior ciliary artery tears into the suprachoroidal space. From the above report, blocked circulatory arrest combined with a sudden reduction in intraocular pressure appears to be the primary cause of fulminant choroidal hemorrhage, especially in glaucoma. This article aims to study the blocked choroidal venous obstruction, is a factor of fulminant choroidal hemorrhage.
