Abstract Details

Purpose:

To provide a normative data for macular thickness in healthy Iraqi eyes using Zeiss cirrus HD-OCT and to determine the effects of age and gender on their measurements.

Setting:

Dr Ahmed Ali Ibrahim / Ibn-Alhaithem Teaching Eye Hospital/ Baghdad/ IRAQ

Methods:

: Two hundred healthy adult volunteers (≥20 years) underwent macular scanning using Zeiss cirrus-HD OCT. Macular thickness from all 9 regions of the Early Treatment Diabetic Retinopathy Study map was documented for each subject. Variations in macular thickness by age and gender were determined.

Results:

The mean age of volunteers was 37±10.4 (range 21-67)years. The mean of central foveal thickness was 254.6±17.3Mm, the mean macular thickness was 279.0 ± 10.7 Mm, and the macular volume was 10.0 ± 0.4 mm3.Females were found to have a significantly thinner macula (P< 0.001) than males in all 9 ETDRS regions except outer inferior quadrant. Central foveal thickness was found to have very weak correlation with age which was not statistically significant. All other macular regions, mean macular thickness and volume showed statistically significant nonlinear decrease with age(p value<0.001).

Conclusions:

This is a normative data for macular thickness in healthy Iraqi eyes using Zeiss cirrus HD-OCT. This will serve as a baseline for diagnosing and treating macular pathologies among Iraqi patients.
