We report a 23-year-old female patient with ophthalmic features of albinism, including refractive errors, nystagmus, depigmented fundus, and foveal hypoplasia. She presented for a rhegmatogenous retinal detachment, which was surgically reattached with no complications. Further genetic testing revealed the presence of a heterozygous pathogenic oculocutaneous albinism OCA2 gene mutation, conferring carrier status. To the best of our knowledge, this is the first reported case of typical ocular phenotype of albinism, specifically nystagmus, in a patient who is carrier for oculo-cutaneous albinism. Further research is required to expand the genotype-phenotype relationship in carriers of oculocutaneous albinism. .
我们报告了一例具有白化病眼部特征的 23 岁女性患者,包括屈光不正、眼球震颤、眼底色素减退和黄斑发育不良。她因孔源性视网膜脱离就诊,手术复位后无并发症。进一步的基因检测显示存在杂合致病性眼皮肤白化病 OCA2 基因突变,为携带者状态。据我们所知,这是首例报道的白化病患者出现典型眼部表型,特别是眼球震颤的病例,该患者为眼皮肤白化病的携带者。需要进一步研究以扩大眼皮肤白化病携带者的基因型-表型关系。
