Abstract Details

Purpose:

The aim of this study was to evaluate changes of intraocular pressure (IOP) one months after cataract surgery (CS) in glaucomatous and non-glaucomatous eyes.

Setting:

Riga Stradins University, Latvia

Methods:

This was a retrospective case series study including 20 eyes with senile cataract in each group. Patients only with primary open-angle glaucoma and IOP<21 mmHg were included in the glaucomatous eye group (the study group). Criteria for the control group were following: no glaucoma, IOP<21 mmHg and open angle (grade 4 or 3).  All patients underwent an uncomplicated cataract surgery. Only one eye per patient was involved in the study. After surgery, glaucoma patients continued their topical hypotensive eye drops as previously prescribed. The exclusion criteria were pseudoexfoliation syndrome, pigment dispersion syndrome, previous corneal and glaucoma surgery.

Results:

The average patients’ age was 62.4 ± 5.0 years in the study group versus 70.8 ± 4.5 years in the control group. The number of glaucoma medications was 1.5±0.6 in the glaucoma group. No statistically significant difference was seen between the study and control groups comparing IOP (16.5±3.9 vs. 17.5±2.2, p=0.53) preoperatively.  After one month, there was no statistically significant difference in IOP (14.8±2.5 vs. 15.5±1.7 mmHg, p=0.21) between the groups. Moreover, significantly lower IOP was obtained in both groups after cataract surgery (p=0.003 in the study group vs. p=0.001 in the control group).

Conclusions:

Cataract surgery provides a decrease of IOP in glaucomatous and non-glaucomatous eyes. No statistically significant difference was seen between both groups comparing IOP one months after surgery.
