[Skin and eyes]

Numerous diseases affect both skin and eyes due to similar ontogenetic origin. The eye is the second most common site of melanoma after the skin. The eyelids are predisposed for development of toxic and allergic dermatitis as the skin in this region is four times thinner than the other facial skin. The differential diagnosis must include atopic and seborrhoeic eyelid dermatitis. Atopic and vernal keratoconjunctivitis are associated with atopic eczema. Various immunobullous disorders involve the conjunctiva with varying severity. Side effects of dermatologic treatments with glucocorticoids, antimalarials, psoralens, retinoids, or tetracyclines may involve the eye.
