Ophthalmologic disorders in minority populations.

Race- and ethnicity-related differences in prevalence of a number ofophthalmologic disorders have been documented. More importantly, blackand Hispanic Americans share a disproportionate share of morbidity, asmeasured by visual impairment and blindness, when compared with whiteAmericans. The reasons for this health disparity are complex andmultifactorial. If the unequal, individual, and societal burden of avoidable vision lossamong black and Hispanic Americans is to be decreased, it is essential tounderstand the apparent barriers to accessing timely and appropriateophthalmologic monitoring and care for these minority populations. Forthose who do gain access to ophthalmologic care, it is important tounderstand better the determinants leading to different treatment of blackand Hispanic Americans compared with white Americans. Opportunities for decreasing vision-related morbidity caused by cataract,diabetic retinopathy, and glaucoma for these minority groups clearly exist. Strategies for each of these ophthalmologic disorders may differ. Cataract isa reversible cause of visual impairment and removal of cataract improvesquality of life. Cataract surgery should be offered to all who can potentiallybenefit from this treatment. Earlier diagnosis, before the disease hasprogressed to loss of vision, should be a goal in both glaucoma and diabeticretinopathy. Strategies for screening high-risk groups may be particularlyrelevant in this regard. Additionally, with diabetic retinopathy, improvedmanagement of contributing risk factors, such as blood glucose control andblood pressure control, is important. Asian Americans are increasingly becoming a sizable minority group inthe United States. It is projected that by 2070, the Asian population willreach 11% of the total population of the United States. Virtually all of thepopulation-based data relating to ophthalmologic disorders in Asians havebeen performed in Asia. The reported relative proportion of PACG versusPOAG, however, among some Asian populations and of normal-tensionglaucoma versus high-tension glaucoma among the Japanese seems to applyto the United States Asian population. This assertion is based onwidespread clinical impression and analysis of Medicare claims data [56]. Understanding the differences is important for optimal treatment of theseminority populations as the proportion of Asians in the United Statescontinues to grow. The common denominator in all of these diseases is the role of thephysician and patient. Educational programs aimed at the physician tofacilitate cultural competence and at the patient to increase level of knowledgeabout their disease are appropriate and enthusiastically endorsed.
