The clinical features in patients with newly diagnosed pseudoexfoliative glaucoma in Serbia

Abstract

Purpose:

To evaluate the clinical characteristics of newly diagnosed pseudoexfoliative glaucoma and compare them with those pertaining to newly diagnosed primary open-angle glaucoma as well as pseudoexfoliation syndrome.

Methods:

This case–control study involved 306 participants, including patients with newly diagnosed pseudoexfoliative glaucoma, age- and sex-matched normal controls, patients with newly diagnosed primary open-angle glaucoma, and subjects with pseudoexfoliation syndrome. The study was conducted at the Glaucoma Department of Clinic for Eye Diseases, Clinical Center of Serbia, as the referral center for glaucoma in Serbia.

Results:

The mean age in the pseudoexfoliative glaucoma, primary open-angle glaucoma, pseudoexfoliation syndrome, and normal control groups was 73.61 ± 8.46, 65.50 ± 8.97, 74.81 ± 6.80, and 73.58 ± 9.34 years, respectively (pseudoexfoliative glaucoma vs primary open-angle glaucoma, p < 0.001). Unilateral pseudoexfoliative glaucoma was diagnosed in 35 patients (42.2%). The intraocular pressure was higher in the eyes affected by pseudoexfoliative glaucoma (32.0 ± 9.5 mmHg) than that in the primary open-angle glaucoma eyes (28.8 ± 5.9 mmHg) (p < 0.001). In pseudoexfoliative glaucoma and primary open-angle glaucoma eyes, glaucoma severity was determined via the vertical cup-to-disk ratio (C/D) 0.65 (0.45–1.0) versus 0.60 (0.45–1.0), p = 0.048 and visual field mean deviation −5.68 (−1.58 to −30.9) versus −4.70 (−1.39 to −31.0), p = 0.045. Alzheimer’s was the only systemic disease associated with pseudoexfoliative glaucoma in the study sample, with an odds ratio of 0.021 (95% confidence interval = 0.00−21.52, p = 0.022).

Conclusion:

At the time of diagnosis, pseudoexfoliative glaucoma exhibits different clinical features compared with primary open-angle glaucoma. Higher intraocular pressure, narrow or occludable angle, increased trabecular pigmentation, phacodonesis, and poorer pupillary dilatation emerged as the factors associated with pseudoexfoliative glaucoma.
