A Mild Form of RPE65-Associated Retinopathy
Milde Präsentation einer RPE65-assoziierten RetinopathieIntroduction
Biallelic mutations in RPE65 give rise to a spectrum of retinal phenotypes ranging from Leber congenital amaurosis (LCA) and early-onset severe retinal dystrophy (EOSRD) to juvenile retinitis pigmentosa (RP) [1], [2].
Since 2017, voretigene neparvovec (VN) has offered the first approved gene therapy in ophthalmology for patients with biallelic mutations in RPE65, representing a milestone in ophthalmic therapy for inherited retinal dystrophies (IRDs) [3].
We present a rare case of a 42-year-old male with biallelic RPE65 mutations, exhibiting an unusually mild phenotype, questioning the decision for or against subretinal gene therapy under these circumstances.
