ABSTRACT
Ocular involvement of lichenoid dermatoses, such as lichen planus (LP), lichen planus pigmentosus (LPP), and lichen planopilaris (LPL), although uncommon, is associated with skin manifestations. Isolated ocular involvement is very rare. When lesions are confined to the skin, the dermatologist inquires and evaluates for oral and genital symptoms and lesions, respectively; hence, eye manifestations are commonly neglected by the non-ophthalmologist. Ocular involvement in LP, LPP, and LPL may result in significant morbidity. An ophthalmic interrogatory and a gross ophthalmic evaluation performed by the dermatologist may unravel ocular signs and symptoms that require evaluation by an eye specialist. Ocular surface inflammation and scarring, when untreated, results in serious complications such as corneal perforation and permanent vision loss. This review aims to present an up-to-date overview for the dermatologist of the ocular involvement and complications of LP, LPP, and LPL, and when to refer to the ophthalmologist to prevent blinding complications.
