Retinitis pigmentosa-87 with choroidal involvement (RP87) is characterized by a slowly progressive visual disturbance, including night blindness and reduced central and peripheral vision, accompanied by extensive choroid/retinal atrophy that mimics certain aspects of choroideremia. Disease severity and age of onset are variable, and some carriers are unaffected (Hull et al., 2016; Li et al., 2019).
