无脉络膜脱离或出血的无晶体眼,虽作过虹膜切除,但仍可发生持续性浅前房或无前房,称之为无晶体性恶性青光眼。可能系由于近年来白内障囊内摘除术后行前房型人工晶体置入所致,此种情况较为普遍,通常需手术切除玻璃体以恢复正常的前房深度。作者以前的实验室研究证实shaffer的临床观察,即此种情况的异常部位,系玻璃体前膜。因此,在玻璃体切除手术前,可采用钕-YAG激光切开玻璃体前膜以治疗此症。初步经验表明,此疗法简单、有效。本文报告5例5眼,3眼为无晶体;2眼为人工晶体置人。尽管作了激光虹膜打孔术或手术
Aphakia without choroidal detachment or hemorrhage, despite the iris resection, but can still occur persistent shallow anterior chamber or anterior chamber, called aphakic malignant glaucoma. It may be due to the recent years after intracapsular cataract extraction of anterior chamber intraocular lens implantation caused by this situation is more common, usually require surgical removal of the vitreous to restore normal anterior chamber depth. The authors previous laboratory studies confirm the clinical observation of shaffer, the anomalous site of this condition, is the anterior vitreous. Therefore, before vitrectomy surgery, neodymium-YAG laser can be used to incise the anterior vitreous membrane to treat this condition. Preliminary experience shows that this therapy is simple and effective. This article reports 5 cases in 5 eyes, 3 eyes without lens; 2 eyes with artificial lens. Despite laser iridectomy or surgery
