To estimate the occurrence of choroidal detachment (CD) in 17 patients operated on with trabeculectomy.
Ultrasonography was used to assess the occurrence of CD and pachymetry was used to estimate the depth of the anterior chamber (AC). Mean follow-up was 19 months.
Twelve (71%) patients suffered from marked hypotony (IOP < or =5 mm Hg) and 9 (53%) patients suffered from shallowing of the AC some period early after operation. CD was diagnosed in 10 (59%) patients. Ophthalmoscopy was not sufficient to diagnose CD in 3 (18%) patients. None of the eyes without CD showed more than 10% reduction of the AC. Four of these eyes were markedly hypotonic. On the other hand, all markedly hypotonic eyes with more than 10% reduction of the AC developed CD.
No postoperative IOP level alone could separate patients at risk for CD development from patients without any such risk. However, concomitant marked hypotony and more than 10% reduction of the AC were found in 2/3 of the CD eyes.
评估17例行小梁切除术患者脉络膜脱离（CD）的发生率。
采用超声检查评估CD的发生情况，用测厚法估计前房（AC）深度。平均随访时间为19个月。
12例（71%）患者出现明显低眼压（眼压≤5 mmHg），9例（53%）患者在术后早期某个阶段出现前房变浅。10例（59%）患者被诊断为脉络膜脱离。检眼镜检查不足以诊断3例（18%）患者的脉络膜脱离。没有脉络膜脱离的眼中，没有一只眼的前房减少超过10%。其中4只眼为明显低眼压。另一方面，所有前房减少超过10%的明显低眼压眼均发生了脉络膜脱离。
仅术后眼压水平无法区分有脉络膜脱离发生风险的患者和无此风险的患者。然而，在2/3发生脉络膜脱离的眼中发现了同时存在的明显低眼压和前房减少超过10%的情况。
