Abstract

Purpose : To evaluate the risk factors for choroidal detachment after trabeculectomy.

Methods : We prospectively evaluated 109 open angle glaucoma patients who underwent primary trabeculectomy.
The main outcome measure was the risk factors for the occurrence of choroidal detachment and the severity after trabeculectomy. The severity of choroidal detachment was quantified as the number of fundus quadrants which were occupied by choroidal detachment.

Results : Eighteen patients (16.8%) encountered choroidal detachment. The mean period between the surgery and choroidal detachment was 7.4 ± 5.6 days. The mean intraocular pressure (IOP) on the first day of choroidal detachment was 6.4 ± 3.2 mm Hg. Our multivariable analyses showed that the greaterΔIOP between preoperative and postoperative IOPs was a significant risk factor for choroidal detachment (P =0.001). The more severe choroidal detachment was associated with the greater ΔIOP (P <0.001) as well as pseudophakic eyes (P = 0.011).

Conclusions : The more IOP reduction after trabeculectomy might cause choroidal detachment. In addition to more IOP reduction, pseudophakic eyes frequently encounter severe choroidal detachment after trabeculectomy.
