ABSTRACT
INTRODUCTION:
Our goal was to evaluate the normal macular thickness in Blacks by OCT and to determine socio-demographic and clinical parameters which may influence it. MATERIALS ANDMETHODS:
This was a multicenter, prospective, descriptive study over 6 months. It included Black adults followed in the ophthalmology departments of Abass Ndao and Aristide-Le-Dantec hospitals in Dakar. Included subjects had corrected visual acuity of 10/10 (0 logMAR) and P2 (+0.1 logMAR), clear ocular media, and no retinal abnormalities. We used the Topcon 3D 2000 OCT to measure the central thicknesses of the cornea (CT) and of the macula (MT), and cup to disc ratio (C/D) in each eye. Socio-demographic, clinical and tomographic data were collected on a survey form and correlated to the MT. The analysis was carried out by the Epi info 7 software. We used the Chi2 comparison test with a P valueË0.05.RESULTS:
One hundred and nine patients were included. The mean age was 27.39 years with a male/female ratio of 0.65. The subjects were emmetropic in 54.13% of cases. The mean CT was 519.97µm, the mean C/D was 0.23, and the mean MT was 264.35µm. The P-value (P) was greater than or equal to 0.1 for all the factors studied.CONCLUSION:
MT in our study was lower than that of Whites, and the various parameters studied did not demonstrate a statistically significant influence on MT.Palabras clave
