Description
Rami Akwan and co-authors profile a 2026 clinic sample of keratoconus, the cone-shaped corneal disease, at Damascus Hospital in Syria. Local data were scarce. The prospective study examined 173 eyes from 93 patients with Pentacam tomography and careful refraction, grading severity with the Buxton keratometric system.
Patients averaged 29.7 years old, and 92.5 percent had both eyes affected in the sample. Mild and moderate grades dominated, at 45.1 and 43.9 percent of eyes respectively. Disease grade associated significantly with gender but not with age. Oblique compound myopic astigmatism was the commonest refractive error, at 25.4 percent of eyes counted. Steeper corneas tracked strongly with bigger refractive error, while thinner corneas tracked weakly the other way. The authors call the Syrian profile much like regional reports.
