Dominant cystoid macular dystrophy (DCMD) is a progressive retinal dystrophy characterized primarily by early-onset cystoid fluid collections in the neuroretina (summary by Saksens et al., 2015).

Inability to see well at night or in poor light.

Optic disc drusen are acellular, calcified deposits within the optic nerve head. Optic disc drusen are congenital and developmental anomalies of the optic nerve head, representing hyaline-containing bodies that, over time, appear as elevated, lumpy irregularities on the anterior portion of the optic nerve.

A nonspecific term denoting degeneration of the retinal pigment epithelium and/or retinal photoreceptor cells.

An absolute or relative decrease in retinal sensitivity extending from edge (periphery) of the visual field in a concentric pattern. The visual field is the area that is perceived simultaneously by a fixating eye.

A cataract that affects the region of the lens directly beneath the capsule of the lens.

The presence of small, white vitreous opacities consisting of calcium phosphate and complex, layered lipid deposits.

Pigment migration into the retina in a bone-spicule configuration (resembling the nucleated cells within the lacuna of bone).

An inherited retinal disease subtype in which the rod photoreceptors appear to be more severely affected than the cone photoreceptors. Typical presentation is with nyctalopia (due to rod dysfunction) followed by loss of mid-peripheral field of vision, which gradually extends and leaves many patients with a small central island of vision due to the preservation of macular cones.
