Visual acuity testing before and after intravitreal injection of rAAV2-ND4 in patients

Abstract

Gene therapy in ophthalmology has developed rapidly, and there has been a breakthrough in the treatment of Leber’s hereditary optic neuropathy. After receiving an intravitreal injection of rAAV2-ND4, patients followed up over a certain time period showed a definite increase in visual acuity. Visual acuity testing is critical for assessing the efficacy of rAAV2-ND4 intravitreal injection.
