Summary
The mean IOP reduction 6 months after phacoemulsification was 20%. Less IOP reduction was observed in the presence of lower preoperative IOP and more extensive PAS.
Abstract
PURPOSE
To evaluate the intraocular pressure (IOP) change and associated factors 6 months after phacoemulsification in eyes with primary angle-closure suspect (PACS) and eyes with primary angle closure (PAC) that had no medical therapy.
SETTING
Singapore National Eye Center, Singapore, Singapore.
DESIGN
Retrospective case series.
METHODS
Patients with PACS or PAC (with corrected distance visual acuity .05). In multiple linear regression analyses, a higher preoperative IOP (β = 0.68, P < .001) and fewer clock hours of peripheral anterior synechiae (PAS) (β = -0.30, P = .03) predicted a greater absolute change in and percentage of reduction in IOP, respectively.
CONCLUSIONS
The mean IOP reduction 6 months after phacoemulsification was 20%. Less IOP reduction was observed in the presence of lower preoperative IOP and more extensive PAS.
