Retinitis pigmentosa-78 (RP78) is an autosomal recessive retinal dystrophy that presents in the third to fourth decade with central visual disturbance, visual field defects, and nyctalopia. Fundus examination reveals optic disc pallor, attenuated retinal vessels, and irregular midperipheral intraretinal pigment migration (Arno et al., 2017).
