Forty-one patients presenting consecutively with acute angle closure glaucoma (AACG) were studied with a median follow-up period of eight months. Four patients presented with bilateral symptoms. Thirty-nine patients underwent Nd-YAG laser iridotomy (42 AACG eyes and 36 fellow eyes). Only 15 patients (36.6%) required simply iridotomy; the remainder required additional long term medical or surgical treatment. Longer duration of symptoms and a history of previous intermittent, spontaneously resolved AACG were more common in those requiring additional treatment. Cataract extraction with intraocular lens implantation was performed for three eyes with AACG, and this mode of treatment is discussed as a possible primary treatment. One eye with AACG suffered a second episode, and two fellow eyes developed AACG despite laser iridotomy. Possible mechanisms are discussed. Provocative testing or frequent careful observation of iridotomy patency is recommended.
对连续就诊的41例急性闭角型青光眼(AACG)患者进行了研究,中位随访期为8个月。4例患者表现为双侧症状。39例患者接受了Nd-YAG激光虹膜切开术(42只患眼和36只对侧眼)。仅15例患者(36.6%)仅需行虹膜切开术;其余患者需要额外的长期药物或手术治疗。症状持续时间较长以及既往有间歇性、自行缓解的AACG病史在需要额外治疗的患者中更为常见。对3只AACG患眼进行了白内障摘除联合人工晶状体植入术,并讨论了这种治疗方式作为一种可能的初始治疗方法。1只AACG患眼出现了第二次发作,2只对侧眼尽管接受了激光虹膜切开术仍发生了AACG。文中讨论了可能的机制。建议进行激发试验或频繁仔细观察虹膜切开术的通畅情况。
