Doyne honeycomb retinal dystrophy (DHRD) is a disorder that affects the eyes. It is characterized by small, round, white spots known as drusen that accumulate beneath the retinal pigment epithelium (a layer of cells deep in the retina that helps maintain the function of the photoreceptor cells). Over time, drusen may enlarge and come together, creating a honeycomb pattern. It typically begins in early to mid adulthood, but age of onset varies. The degree of gradual vision loss varies among affected individuals. DHRD is usually caused by mutations in the EFEMP1 gene and is inherited in an autosomal dominant manner.[1][2][3]
