The eyes and the eyelids can occasionally be involved. Typically, there is an increased reactivity of capillaries to heat, leading to flushing and ultimately telangiectasia. Subtypes of rosacea include (1) vascular rosacea (erythematotelangiectatic), (2) papulopustular rosacea, (3) sebaceous hyperplasia (phymatous rosacea) including rhinophyma (nasal sebaceous hyperplasia), and (4) ocular rosacea. Granulomatous rosacea is a variant of rosacea.
