ABSTRACT
Introduction: papilledema refers to the swelling of the head of the optic nerve, a major sign of many local, locoregional or systemic pathologies that may involve patients' visual or vital prognosis. This condition represents a diagnostic and therapeutic emergency frequently encountered in our facilities. Therefore, it is deemed and opportune to identify the most common etiologies observed in Cameroonian hospitals. Method: we conducted a documentary and descriptive study of patients with papilledema presenting to the Ophthalmology Department of the Hospital of Instruction, Application and Reference of the Armed Forces of Yaoundé from 1st October 2013 to 31st December 2016. The variables under investigation included epidemiological data (age, sex), clinical data (functional signs, visual acuity, appearance of the papilla and associated signs according to the Hoyt and Beesten classification), complementary examinations performed (fluorescein angiography, visual field, biology, radiography, CT scan) and the etiological diagnosis. Epi-info 3.5.3 software was used for statistical analysis and the Chi-square test was performed at a 5% significance level (p < 5%). Results: during the study period, papilledema was found in 26 out of 5023 patients, reflecting a rate of 0.5%. The average age of patients was 32.7± 10.9 years, ranging from 7 to 79 years, for 13 women and 13 men. Papilledema was bilateral in 15 (57.7%) patients and unilateral in 11 (42.3%), or 41 affected eyes. The etiologies were 11 (42,3%) inflammatory optic neuropathies, 5 (19,2%) arterial hypertension, 4 (15,4%) central retinal vein occlusions, 3 (11,5%) eye contusions, 2 (7,7%) hydrocephalus and 1 case (3,9%) of cerebral malaria. Conclusion: inflammatory and vascular optic neuropathies were the most common etiologies of papilledema in our facilities.
