Reticular pigmentary retinal dystrophy is a form of patterned dystrophy (see MDPT1, 169150) characterized by a reticular pattern of pigmentation that likely appears in infancy and may be fully developed at age 15 years. Indirect funduscopy has shown that the condition is bilateral and symmetric and that the pigmentary deposits are localized below the neuroepithelium, very likely in the pigment epithelium. The reticulum extends from the macula in all directions, sparing the midperiphery and periphery. Visual acuity is unaffected or only minimally affected in advanced stages. Retinal function testing is normal, although the electrooculogram and dark adaptation can be at the lower limit of normal values (summary by Schauwvlieghe et al., 2013). [from
