Abstract Details


To analyze the effect of cataract surgery on diurnal intraocular pressure (IOP) fluctuation in primary angle-closure glaucoma (PACG) eyes.


Mugla University Faculty of Medicine, Ophthalmology Department


Thirty-nine eyes of 24 patients with PACG scheduled for cataract surgery were enrolled to this prospective study. A record was made which included daily IOP measurements, anterior chamber depth (ACD), anterior chamber angle (ACA), number of antiglaucomatous medications, visual field analysis (mean deviation-MD and pattern standard deviation-PSD) and responses to the Glaucoma Quality of Life-15 (GQL-15) questionnaires. The eyes were re-evaluated at 2 and 3 months of cataract surgery.


IOP fluctuation was decreased from 4.58±2.07 mm Hg to 2.84±1.5 mm Hg (P˂0.001). The decrease in mean IOP, the number of glaucoma eye drops required (P˂0.001, P=0.012, respectively) and the increase in mean ACD, ACA grading, and SITA-standard MD (P<0.001, P<0.001, and P=0.01, respectively) were statistically significant. The mean GQL-15 score was also improved (P˂0.001). In multivariate analysis, for each unit increase in the change in ACD and preoperative IOP fluctuation, there was an increase in the change in IOP fluctuation with an average of 1.05 mm Hg and 1.1 mm Hg respectively.


Cataract surgery in PACG provides the opportunity to address many pathologies with one intervention; improving vision, diminishing IOP, blunting IOP fluctuation, reducing need for medications, eliminating a narrow angle, and improving GQL-15 scores.
