[Etiologies of papilledema in Cameroonian hospitals]. / Etiologies des œdèmes papillaires en milieu hospitalier camerounais.

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.

Assessment of Systems and Services for Management of Diabetes and Diabetic Retinopathy in Cameroon.

AIM: To evaluate systems and services for management of diabetes and diabetic retinopathy. METHODOLOGY: The National Program for Blindness Control conducted a nationwide descriptive study from 1st February to 31st October 2016. Data was collected using WHO's:"Tool Assessment of Diabetic Retinopathy and Diabetes Management Systems" adapted to the context. Using direct interviews, all previously identified stakeholders, were involved from all levels of management and throughout the territory. The IBM version 20 software permitted analysis. RESULTS: Out of the 48 individuals selected, 46 agreed to participate in the survey. Four participants (8.7%) worked at the central level of the Ministry of Public Health, 2 (4.4%) were NGOs partners, 6 (13%) diabetic patients, and 34 (73.9%) health staff. According to the answers of participants, diabetes stands among priorities in the national health policy. Diabetic care services have been integrated into the National action plan for Chronic Non-Communicable Diseases, but a specific program for control of diabetes has not been created neither are national guidelines recommended by the Ministry available. Some health facilities provide care for diabetes and its complications. Modern technologies for evaluation and follow-up of diabetes of its complications are available only in tertiary level hospitals and in some private clinics. The cost of care obtained is the responsibility of the patients and families. CONCLUSION: The political will to manage diabetes and diabetic retinopathy is recognized by stakeholders and beneficiaries but not translated into an effective program. A suitable implementation strategy is necessary.
