Rosacea

This is a skin disorder where there is fixed or recurrent erythema, telangiectasia, oedema, papules and pustules affecting the forehead, cheeks, nose and often the chin.

It is most often seen in people with fair skin that burns easily but can also occur in people of African descent (1).

It is relatively common, with a female prevalence of 5% and a male prevalence of just under 4% for men (2) but men are more likely to progress to severe disease (2).

The onset is typically between the ages of 30 and 60 (3).

Ocular changes are the initial presentation in 20% of patients (4).
