Oculocutaneous albinism (OCA) is a genetically inherited autosomal recessive condition. Individuals with OCA lack melanin and therefore are susceptible to the harmful effects of solar ultraviolet radiation, including extreme sun sensitivity, photophobia and skin cancer. OCA is a grave public health issue in sub-Saharan Africa with a prevalence as high as 1 in 1000 in some tribes. This article considers the characteristics and prevalence of OCA in sub-Saharan African countries. Sun-induced adverse health effects in the skin and eyes of OCA individuals are reviewed. Sun exposure behavior and the use of photoprotection for the skin and eyes are discussed to highlight the major challenges experienced by these at-risk individuals and how these might be best resolved.
眼皮肤白化病(OCA)是一种常染色体隐性遗传疾病。患有OCA的个体缺乏黑色素,因此易受太阳紫外线辐射的有害影响,包括对阳光极度敏感、畏光和皮肤癌。在撒哈拉以南非洲地区,OCA是一个严重的公共卫生问题,在一些部落中患病率高达千分之一。本文探讨了撒哈拉以南非洲国家OCA的特征和患病率。综述了阳光对OCA个体皮肤和眼睛产生的不良健康影响。讨论了OCA个体的日晒行为以及皮肤和眼睛的光保护措施,以突出这些高危个体所面临的主要挑战以及如何最好地解决这些问题。
