AIM: To compare the efficacy of early phacoemulsification versus peripheral iridotomy for primary angle-closure glaucomatous patients with cataract and better visual acuity. METHODS: A prospective randomized controlled trial was performed. 48 eyes of 48 cases were categorized into two groups according to the operation method. Group A (24 eyes) were undertaken cataract phacoemulsification; group B(24 eyes) were undertaken peripheral iridotomy . Patients were followed up for 1day, 7days, 1month, 3months and 6months. The postoperative visual acuity (VA) were analyzed and compared between the two groups, as well as intraocular pressure (IOP) ,central anterior chamber depth (CACD) and peripheral anterior chamber (PACD). RESULTS: The IOP one day after the operation was significantly higher in group A than that in group B, and three days latter the IOP of group A reduced to normal level. There was no statistically significant difference between the two groups. In group A, the CACD varied from 2.25 ± 0.09mm (preoperative) to 3.21 ± 0.11mm (postoperative), and the difference was significant (P < 0.05), There was no statistically significant difference before and after the operation in group B. The PACD in all eyes in group A deepened significantly (P < 0.05), while in group B it did not. In group A, the postoperative VA (0.52 ± 0.15) of all patients improved in different degrees, while in group B the VA after peripheral iridotomy was as poor as the preoperative VA. There was statistically significant difference between the two groups (P < 0.05). CONCLUSION: Early phacoemulsification appeared to be more effective in preventing IOP rise than peripheral iridotomy in patients with acute primary angle-closure glaucoma and primary angle-closure glaucomatous with cataract. And it can be considered as a definitive treatment to prevent IOP rising. LA: Chinese
