[Contribution of Optical Coherence Tomography in the evaluation of the iridocorneal angle in Cameroon].

Introduction: Our work was aimed at determining the sensitivity and specificity of anterior segment OCT (AS-OCT) in the evaluation of the iridocorneal angle (ICA) in Cameroon.

Methodology: We conducted a cross-sectional, analytical study from January 2 to June 30, 2019 in Yaoundé. One hundred and twenty five patients over 35 years of age underwent three-mirror manual glass gonioscopy and AS-OCT.

[Measurement of lacrimal secretion in chronic hemodialysis patients at Douala General Hospital - Cameroon].

Purpose: To measure lacrimal secretion and to investigate dry eye symptoms in chronic hemodialysis patients.

Patients And Methods: This was a cross-sectional descriptive study carried out in the hemodialysis center of Douala General Hospital from June to August 2016. The degree of symptomatology related to dry eye was assessed by the Ocular Surface Disease Index (OSDI) questionnaire.

[Meibomian glands dysfunction and ocular surface in black people].

Unlabelled: Meibomian gland dysfunction is the leading cause of evaporative-type dry eye syndrome. Our goal was to determine the epidemiological and clinical features of meibomian gland dysfunction as well as its impact on the ocular surface in elderly black patients in Cameroon.

Patients And Methods: We performed a cross-sectional analysis from January 2 through May 31, 2017 in the ophthalmology department of Laquintinie Hospital in Douala, including blacks aged 50 years and older.

Association of insulin treatment versus oral hypoglycaemic agents with diabetic retinopathy and its severity in type 2 diabetes patients in Cameroon, sub-Saharan Africa.

Background: Type 2 diabetes mellitus (T2DM) is a chronic metabolic disease associated with multiple macro and microvascular complications, diabetic retinopathy (DR) being the commonest one. Recent literature has reported an increased risk of DR with insulin use.

Methods: We carried out a cross-sectional study at the Ophthalmology Department of the Douala General Hospital (DGH) during a 2-year period to explore the association between insulin treatment and both DR and its severity as compared with oral hypoglycemic agents (OHAs) in Cameroonian T2DM patients aged ≥35 years, and who were all screened for DR through eye examination including exhaustive retinal evaluation.

Diabetes and visual impairment in sub-Saharan Africa: evidence from Cameroon.

Background: "Vision 2020 - the right to sight" is a program which purpose is to eliminate avoidable blindness by the year 2020 through the implementation of concrete action plans at the national and district levels. Accordingly, baseline data are needed for the planning, monitoring, follow-up and evaluation of this program. The present study aimed to better characterize visual impairment and blindness in Cameroonian diabetics by providing with baseline data on the prevalence and main causes of these affections.
