摘要

AIM: To assess the changes in the anterior chamber parameters using Pentacam following four different lines of treatment of primary angle-closure glaucoma(PACG).METHODS: A retrospective comparative study included 126 patients(126 eye) presented within 24-48 h after acute angle-closure glaucoma(AACG). Patients were divided into 2 groups: group A(68 eyes) with controlled intraocular pressure(IOP) ≤21 mm Hg, which included subgroup A1(34 eyes) with clear lens underwent Nd:YAG laser peripheral iridotomy(LPI) and subgroup A2(34 eyes) with cataract underwent standard phacoemulsification;and group B(58 eyes) with uncontrolled IOP, which included subgroup B1(30 eyes) with clear lens underwent trabeculectomy and subgroup B2(28 eyes) with cataract underwent combined phacoemulsification and trabeculectomy. Patients were fol owed up for at least 3 mo. Primary outcomes were Pentacam anterior segment measurements [anterior chamber angle(ACA) and depth(ACD)]. Secondary outcomes were changes in IOP, visual acuity(VA) and recorded complications. RESULTS: At the 3~(rd)month, there was significant increase in the ACA values in all studied groups compared to preoperative values(P<0.001). The highest percent of increase in ACA was recorded in phacotrabeculectomy group B2(128.40%). There was significant increase in ACD values at 3~(rd)month compared with baseline values(P<0.001) for groups A1, A2, and B2;without change in B1 trabeculectomy group. The maximum deepening of ACD was noticed in group B2 with 94.27% increase. Significantdecrease in postoperative IOP in groups A2, B1 and B2(P<0.001, P=0.014, and P<0.001 respectively). In group A1 there was significant increase in 3~(rd)month postoperative IOP from baseline values(P<0.001). The maximum decrease in IOP was noticed in group B2 with 59.54% decrease. VA improvement in 3~(rd)month postoperative was recorded in all studied groups, maximum VA improvement was observed in group B2 up to 0.2 log MAR.CONCLUSION: Pentacam can be a helpful tool in studying and comparing the effect of th
