Retinitis pigmentosa-10 (RP10) is characterized in most patients by early onset and rapid progression of ocular symptoms, beginning with night blindness in childhood, followed by visual field constriction. Some patients experience an eventual reduction in visual acuity. Funduscopy shows typical changes of RP, including optic disc pallor, retinal vascular attenuation, and bone-spicule pattern of pigmentary deposits in the retinal midperiphery. Electroretinography demonstrates equal reduction in rod and cone responses (Jordan et al., 1993; Bowne et al., 2002; Bowne et al., 2006).
