Meibomian gland dysfunction is highly prevalent in elderly black patients in Cameroon, affecting over 70%. This condition, a primary cause of evaporative dry eye, is linked to factors like hypertension and cataract surgery.
Area of Science:
- Ophthalmology
- Epidemiology
- Public Health
Background:
- Meibomian gland dysfunction (MGD) is the primary cause of evaporative dry eye syndrome.
- Understanding MGD's prevalence and impact in specific demographics is crucial for targeted interventions.
Purpose of the Study:
- To determine the epidemiological and clinical features of MGD.
- To assess MGD's impact on the ocular surface in elderly black patients in Cameroon.
Main Methods:
- Cross-sectional analysis of 340 black patients aged 50+ in Douala, Cameroon.
- Ocular examinations included Meibomian gland assessment, Tear Film Break Up Time, and Schirmer I test.
- Linear regression analyzed relationships between MGD and clinical/quantitative variables.
Main Results:
- Prevalence of MGD was 71.8%, with the hypoproductive form being most common (47.9%).
- Evaporative dry eye was the most frequent diagnosis (34.7%).
- MGD was associated with hypertension, cataract surgery, glaucoma medication, and alcohol consumption.
Conclusions:
- Meibomian gland dysfunction is highly prevalent in elderly black patients in Cameroon.
- MGD significantly impacts the ocular surface in this population.
- Further research into risk factors and management strategies is warranted.

Their closest cousins are neutron stars, which are composed almost entirely of neutrons packed against each other, making them extremely dense. A neutron star has the same mass as the Sun but its diameter is only a few kilometers. Therefore, the escape velocity from their surface is close to the speed of light.
Not until the 1960s, when the first neutron...
