Color Vision Deficiency (CVD) is mostly an inherited trait and is not an uncommon problem. Prevalence of CVD differs among different ethnic and geographic properties of the population that affect their genetic constitution. Ishihara plates remain an internationally accepted tool for screening red-green CVD.
To determine the prevalence of red-green CVD among adult males from Baghdad province.
PATIENTS AND METHODS:
One thousand and five (1005) adult males were enrolled in this study, using a systematic sampling technique, and were screened for CVD utilizing 24-plate Ishihara plates and re-tested by EnChroma 39-Color plates. All males were residing in Baghdad and the center of Iraq.
Among all tested males, 948 reside in Baghdad province; of them, 64 showed red-green CVD; thus making prevalence rate of 6.75% in Baghdad province. The deutan/protan ratio was 2.79:1.
