- W4253227355 abstract "Abstract Background Patients with primary angle closure/glaucoma (PAC/PACG) with extensive peripheral anterior synechiae (PAS), and coexisting cataract, increasingly have been treated with phacoemulsification combined with goniosynechialysis (Phaco-GSL). Since the mechanisms of acute and chronic PAC/PACG may differ, the treatment effect of this procedure also may differ. The purpose of this study was to establish whether there was a difference in the therapeutic effect of Phaco-GSL on these two groups of patients, the results of which could provide clinical evidence for improvement in treatment protocols for patients with PAC/PACG and extensive PAS. Methods This study was a retrospective cohort study. Twenty-seven patients, 13 with acute PAC/PACG and 14 with chronic PAC/PACG, were treated surgically by Phaco-GSL. The intraocular pressure (IOP), surgical success rate, the need of medication, the extent of PAS, the time and the rate of recurrence of PAS (re-PAS) and other indicators were observed post-operatively for at least three months. Results After surgery, IOP decreased (preoperative vs postoperative: 29.77±11.55 mmHg vs 14.92±1.66 mmHg in the acute group and 26.00±11.2 mmHg vs 14.93±2.7 mmHg in the chronic group), the extent of PAS reduced (preoperative vs. postoperative: 314.23±49.07° vs 116.54±73.78° in the acute group and 285.00±53.28° vs 156.43±56.35° in the chronic group), the topical and systemic anti-glaucoma drug requirements decreased, in both groups and in the acute group, respectively. Compared with the acute group, the success rate (acute vs chronic: 100% vs 64.3%) was lower in the chronic group, while the incidence of re-PAS (acute vs chronic: 30% vs 83.3%) were higher in the chronic group. All differences mentioned above were statistically significant (p < 0.05). In addition, there were five patients in total who showed re-PAS of more than 90° (4 in chronic group and 1 in acute group) and all these re-PASs formed within 1 week postoperatively. Conclusion Although Phaco-GSL is effective in both groups, there may be differences in the effect between the two groups. Chronic patients are more susceptible to re-PAS. Thus, these patients should be observed closely and treated appropriately in the early post-surgical time period." @default.
