Clinical Study of Ciliochoroidal Detachment after Acute Episode Period in Primary Acute Angle-Closure Glaucoma

Objective To study the change of intraocular pressure( IOP) and anterior chamber depth ( AD) in primary acute angle-closure glaucoma complicated by ciliochoroidal detachment after acute episode period.To describe the ultrasound biomicroscopic features of acute angle-closure glaucoma with ciliary or choroidal detachment.Methods The clinical data of 40 patients (40 eyes) with ciliary or choroidal detachment out of 160 patients ( 160 eyes) with primary acute angle-closure glaucoma undergoing medical treatment and paracentesis of anterior chamber were analyzed retrospectively. Results After the treatment,IOP decreased from (50.8 ± 5.6) mmHg to (8.3 ± 3.5) mmHg,AD shallowed from( 1.662 ± 0.235) mm to (1.573 ± 0.180) mm by ultrasound biomicroscopy ( UBM) examination.Ciliary detachment was observed in 17 patients.Choroidal detachment was observed in 23 patients.Conclusion It is suggested that primary acute angle-closure glaucoma complicated by ciliochoroidal detachment is related to rapid reduction of IOP.Ultrasound biomicroscopy ( UBM) can offer higher diagnostic value and reliable information to clinic.
