Abstract

Background: Pseudoexfoliative glaucoma is the most common type of secondary open-angle glaucoma. Objective: To describe the proportion and clinical features of pseudoexfoliative glaucoma among glaucomatous patients Materials and method: A retrospective chart review. The collected data were sex, age, family history, clinical features, clinical eyes examination, type of treatment and intraocular pressure outcome. SPSS version 17 was used. Data were presented as frequencies and means. The statistical significance of differences between data was evaluated using Fisher test. P < 0.05 was considered to indicate statistical significance. Results: The proportion of PEXG patients among glaucoma patients was (9.1%). (Females 51.2% and males 48.8%). The mean age of the patients is 67.6 ± 9.8 years. The patients of the age group 60 – 69 years old were predominant. 65.1% had bilateral PEXG. Severe visual impairment (27.9%) found in the right eyes and (34.9%) were in the left eyes. Round regular react pupils were (60.5%) in the right eyes and (74.4%) in the left eyes, followed by relative afferent pupillary defect with (27.9%) in the right eyes and (11.6%) in the left eyes. High IOP > 21 mmHg found in (60.5%) the right eyes and (53.5%) in the left eyes. The cup/disc ratio with > 0.5 in the right eyes of the PEXG patients found in (60.1%). The means of cup/disc ratio in the right and the left eyes were 0.65 ± 0.26 and 0.67 ± 0.28 respectively (p < 0.05). The medication treatment was given for (76.7%) patients and medication + surgical treatment was given for (23.3%). Conclusion: PEXG was more frequently observed in females. The proportion of PEXG patients was (9.1%). Severe visual impairment was predominant in both eyes. A population-based study suggests to further define the prevalence and characteristics of PEXG in Aden and the surrounding governorates.
