The pattern of glaucoma in Menelik II Hospital Addis Ababa, Ethiopia.

OBJECTIVES

To describe the demographic and clinical profiles glaucoma and evaluate the magnitude of blindness among patients with glaucoma.

PATIENTS AND

METHODS

Cases with glaucoma that were seen at Menelik II hospital Addis Ababa between May 10, 1994 and May 9, 1997 were reviewed Data on relevant demographic and clinical variables were collected and analysed.

RESULTS

A total of 1,586 glaucoma patients were seen at the glaucoma clinic during the study period. The male to female ratio was 2:1. The mean age is 51.9 (SD 17.9) years. Those patients above the age of 40 years represented 78% of the total glaucoma population. The prevalence of glaucoma was highest (27.1%) in the age group of 51-60 years. It was bilateral in 806 (51%) of the patients. Primary Open Angle Glaucoma (POAG) was the most frequent type documented in 631 (40%) of the patients, followed by Secondary Glaucomas in 605 (38%), Primary Angle Closure Glaucoma (PACG) in 285 (18%), Normal Tension Glaucoma (NTG) in 36 (2%), and Congenital Glaucoma in 33 (2%). Six hundred fifty six patients (41%) were blind either in one or both eyes. PACG was found to be potentially a blinding type of glaucoma, in which 53% of the patients suffered from blindness. In the other types, poor public awareness and lack of treatment services were the most important factors that largely precopitated the occurrence of blindness.

CONCLUSION

We recommend that, in addition to improving the diagnostic and therapeutic facilities, intensive work be done to increase public awareness on the nature of the disease, to expand the infrastructure and to develop and rationally deploy the required human resources.
