“…[10] Trachoma endemic zones of Africa, Asia, Middle East, and parts of Latin America and Australia have recorded high prevalence of trachoma blindness [11] resulting from cicatricial entropion and trichiasis. [12] Our report, however, shows only two (3.6%) cases of cicatricial entropion were recorded. This may be explained by the fact that trachoma is not present in the southern region where this study was conducted.…”

Ectropion and entropion in sub-Saharan Africa: How do we differ?

This study highlights a difference in etiopathophysiology of ectropion and entropion in a sub-Saharan region when compared to reported data from developed countries. In Nigeria, ectropion (which is often cicatricial) is usually secondary to trauma whereas senile involution is the common cause in many developed countries. This finding has implications in appropriate planning and skill acquisition for surgical correction in this group of patients.

“…Based on previous work,14 16 25 which established the likely demographics of patients presenting to the remote clinics and the likely prevalence of ocular disorders,12 our aim was to enrol at least 1850 patients aged 20 years or older into the study, in order to ensure that at least 1200 patients aged 40 years or older were enrolled. This would allow the detection of the least prevalent major ocular disorder (glaucoma) at an expected prevalence of 0.4% 12…”

This equated to 36% of those aged ≥20 years and 67% of those aged ≥40 years within this district. Slit-lamp examination of the anterior segment and intraocular pressure measurement, followed by stereoscopic slit-lamp fundoscopy of the optic nerve was performed. Selected patients underwent automated visual field testing. The diagnosis of glaucoma was based on pre-existing definitions. Glaucoma prevalence data are presented. Results: Seventeen individuals had glaucoma (0.90%). Causes of secondaryglaucoma were found in 4 with neovascular glaucoma, 2 with uveitic glaucoma and 4 who had developed glaucoma subsequent to trauma or surgery. The remaining 7 had no identifiable cause for their glaucoma and were thus classified as open-angle glaucoma equating to a prevalence of 0.52% (95% C.I 0.14 to 0.90) for those aged ≥40 years. Of these, 4 had an IOP ≤21 mmHg and 3 had an IOP >21 mmHg. Conclusion:The prevalence of open-angle glaucoma among indigenous Australians within central Australia was 0.52% for those aged ≥40 years. After adjustment for the age distribution of our sample, this is one third the prevalence seen among the nonindigenous Australian population and is despite a higher prevalence of ocular parameters considered to be associated with glaucoma.

“…Although decreasing, the prevalence is still above the threshold set by the WHO to represent a serious public health problem . The rates of trichiasis (TT) and corneal opacity in adults in some Indigenous communities have been shown to be between 6% and 14%, and between 2% and 3%, respectively …”
