Abstract

Introduction: Our work aimed to research the clinical profile of patients diagnosed with retinal vein occlusion, at the ophthalmology department of the Central Hospital of Yaoundé.

Materials and Methods: This is a documentary and descriptive study, conducted over a period from 02 January 2015 to 30 October 2020 at the ophthalmology department of the Central Hospital of Yaoundé, over a period of 05 years.

Results: We collected 15 files out of 17962 patients consulted, or 17 eyes with retinal vein occlusion which made a prevalence of 0.09%. The median age of patients was 62 years. The sex ratio was 4 males to 11 females or 0.36. High blood pressure was found in 9 patients, or 60%. Four patients (23.53%) had severely reduced initial visual acuity, consistent with blindness. Retinal hemorrhages were found in all patients. Three patients (17.64%) had macular oedema.

Conclusion: Central retinal vein occlusions are rare and serious conditions in older females. High blood pressure is the most common comorbidity.
