We observed the peripheral choroid; ciliary body, and depth of the anterior chamber by ultrasound biomicroscopy (UBM) in 31 eyes with rhegmatogenous retinal detachment before and after scleral buckling surgery. Scleral encircling was performed in 11 eyes and segmental scleral buckling in 20 eyes.
With UBM, ciliochoroidal detachment was detected in all eyes (100%) following scleral encircling and in 8 eyes (40.0%) following segmental scleral buckling. After scleral encircling procedure, the eyes with preoperatively bullous and wide retinal detachment showed a severe ciliochoroidal detachment and edema of the ciliary body. Shallowing of the anterior camber occurred in all 11 eyes (100%) after scleral encircling and in 12 of 20 eyes (60.0%) after segmental scleral buckling. Marked shallowing with closure of the angle and elevated intraocular pressure occurred in 2 eyes.
The results showed that careful postoperative examinations for the anterior segments, chamber angle, and intraocular pressure are necessary with slit-lamp examination and applanation tonometry after scleral buckling surgery.
我们通过超声生物显微镜（UBM）观察了31例孔源性视网膜脱离患者在巩膜扣带手术前后的周边脉络膜、睫状体及前房深度。其中11例行巩膜环扎术，20例行节段性巩膜扣带术。
UBM检查显示，巩膜环扎术后所有眼（100%）均出现睫状体脉络膜脱离，节段性巩膜扣带术后8眼（40.0%）出现睫状体脉络膜脱离。巩膜环扎术后，术前有巨大且广泛视网膜脱离的眼出现严重的睫状体脉络膜脱离及睫状体水肿。巩膜环扎术后所有11眼（100%）前房变浅，节段性巩膜扣带术后20眼中12眼（60.0%）前房变浅。2眼出现前房角关闭伴明显前房变浅及眼压升高。
结果表明，巩膜扣带术后需要通过裂隙灯检查及压平眼压计对眼前节、房角及眼压进行仔细的术后检查。
