When two layers of the retina separate, the condition is retinal detachment. The retina is the light-sensitive layer lining the back of the eye, and the sensory retina can peel away from its supporting layers underneath. This separation disrupts visual function and is an emergency because prompt treatment is needed to reattach the retina and prevent permanent vision loss. The other terms describe different eye problems: hyperopia is farsightedness due to a refractive error, macular degeneration involves damage to the central retina (the macula) and central vision, and retinitis pigmentosa is a progressive degeneration of photoreceptors leading to peripheral vision loss. Only retinal detachment refers to a physical separation between retinal layers.
