Rosacea is a chronic, inflammatory facial dermatosis commonly found in fair skin tone population. Recent studies have shown the increasing prevalence in the dark skin tone population as well. Ocular involvement is very common and can occur without cutaneous features. Common ocular features are chronic blepharoconjunctivitis with eyelid margin inflammation and meibomian gland dysfunction. Corneal complications include corneal vascularization, ulceration, scarring, and rarely, perforation. Diagnosis is largely based on clinical signs, although it is often delayed in the absence of cutaneous changes, particularly in children. The management ranges from local therapy to systemic treatment, depending on the severity of the disease. There is a positive association between demodicosis and rosacea; however, causality is always argued. In this review, we describe the epidemiology, clinical features, and treatment of rosacea and ocular rosacea.
