Characterization of West African Crystalline Macular Dystrophy in the Ghanaian Population

This study confirms the localization of crystals adjacent to the inner limiting membrane and distribution over lesions in eyes with copathology. The evaluation of OCT images under high contrast allows improved identification. West African crystalline maculopathy may be associated with the CFH-CFHR5 AMD risk locus identified among Whites; however, it is also possible that the combination of crystals and the CFH 402H allele increases the risk for developing late AMD. Further analyses using larger sample sizes are warranted to identify causalities between genotype and WACM phenotype.
