Types of glaucoma in a university health centre in Al‑Ahsa, Saudi Arabia: a pilot study

Objective: The objective was to assess the profile of different types of glaucoma in a University Health Centre in Al‑Ahsa, Saudi Arabia.Materials and Methods: It is a retrospective study in which the files of the patients at King Faisal University Health Centre were reviewed. The data collected included: Age, sex, race, visual acuity, the slit lamp examination findings, the intraocular pressure (IOP) as the average of 3 readings, the cup‑to‑disc ratio (CDR), the visual field changes, and the details of treatment received.Results: Eighty glaucomatous eyes from 50 patients were included in the study. The mean age was 54.8 ± 12.7 years, and the mean IOP was 19 ± 3.9 mmHg that ranged from 11 to 28 mmHg. The mean CDR mean was 0.48 ± 0.16 that ranged between 0.3 and 0.9. Ninety‑one percent of the visual field defects were arcuate scotomata. Primary open‑angle glaucoma (POAG) (60%) was the most predominant type of glaucoma, followed by primary angle closure glaucoma (ACG) (21.3%), secondary OAG (7.5%), and secondary ACG (6.3%). As for the anti‑glaucoma medications, 88% of the studied patients were on more than one medicine.Conclusion: This pilot study has demonstrated that POAG may be the predominant type of glaucoma in Al‑Ahsa, Kingdom of Saudi Arabia (KSA). Apopulation‑based study with a larger sample size is warranted to confirm the outcome and to provide a baseline data on the prevalence of types of glaucoma in this region of KSA.Keywords: Glaucoma, glaucoma types, prevalence, Saudi Arabi
