Abstract
BACKGROUND: Primary open angle glaucoma is often associated with cataract. The correlation between the use hypotensive drops, in particular non-prostaglandin hypotensive drops with preservative, and the change in central retinal thickness after phacoemulsification with intraocular lens implantation continues to be relevant.
 AIM: To evaluate central retinal thickness and pseudophakic cystoid macular edema incidence after phacoemulsification with intraocular lens implantation in patients with primary open-angle glaucoma using non-prostaglandin hypotensive drops with preservatives.
 MATERIALS AND METHODS: 94 patients (108 eyes) with cataract were enrolled in the study, divided into 3 groups: the first group 21 patients (27 eyes), and the second group 21 patients (23 eyes) with primary open-angle glaucoma using non-prostaglandin hypotensive drops with preservative; the third (control) group included 52 patients (58 eyes) without ocular comorbidities. All patients underwent uncomplicated phacoemulsification with intraocular lens implantation. In the post-op period, patients of the first group received topical antibiotics and steroids, patients of the second and the third groups received the same treatment and non-steroidal anti-inflammatory drops as well. Central retinal thickness was measured using optical coherence tomography before surgery, 2 weeks, 2 and 6 months after surgery.
 RESULTS: The central retinal thickness increase in comparison with baseline values was more significant in the first group than in the second and the third groups, and the time of recovery to baseline values during 6 months after surgery was longer. Pseudophakic cystoid macular edema was not identified in any group.
 CONCLUSIONS: The use non-prostaglandin drops with preservative in patients with primary open-angle glaucoma does not affect pseudophakic cystoid macular edema development after uncomplicated phacoemulsification. Instillations of non-steroidal anti-inflammatory drops in the post-op period reduce the time of central retinal thickness recovery to baseline value.
