Retinitis pigmentosa-61 (RP61) is an autosomal recessive photoreceptor degenerative disorder initially characterized by impairment of night vision and midperipheral visual field loss. Bone spicule pigmentation in the retinal periphery is present, and loss of rod function is detected by electroretinography (ERG) (Khan et al., 2011).
