Ocular Rosacea Clinical Presentation
- Author: J Bradley Randleman, MD; Chief Editor: Hampton Roy Sr, MD more...
History
- Facial symptoms
- Recurrent flushing episodes
- Persistent and/or recurrent midfacial erythema
- Acne (adult onset)
- Ocular symptoms
- Dry eyes,[13] irritation, redness, itching, burning, foreign body sensation, and photophobia
- Recurrent styes
- Recurrent eye infections
Physical
Facial findings
- Telangiectasias
- Papules and pustules (without comedones)
- Rhinophyma (hypertrophy of sebaceous glands of the nose leading to bullous tissue hyperplasia)
Ocular findings
- Eyelid (most common)[14]
- Conjunctivitis
- Usually chronic, diffuse hyperemia
- Can lead to cicatrization in rare, severe cases
- Corneal findings
- Punctate epithelial keratopathy (PEK), usually in the inferior one third of the cornea
- Marginal corneal infiltrates
- Corneal neovascularization
- Superficial, wedge-shaped peripheral vascularization with its base at the limbus
- Can progress to frank corneal neovascularization and eventual opacification as shown below
Ocular rosacea. Extensive corneal neovascularization and opacification. - Corneal thinning as depicted below, ulceration, and perforation
Ocular rosacea. Extensive corneal pannus with thinning.
- Secondary bacterial keratitis
- Episcleritis, scleritis (rare)
Causes
- Flushing triggers: These include alcohol, hot beverages, tobacco, spicy foods, vasodilating medications, and emotional stress.
- UV sunlight: This is postulated to decrease the competence of already dilated cutaneous vasculature, increasing persistent erythema and telangiectasias.
- Migraines: Studies have shown an increase in rosacea in patients with migraine headaches. It is postulated that patients with rosacea have a vasculature prone to vasodilation.[15]
- Demodex: This is Postulated to increase the inflammatory reaction of the sebaceous glands. Prevalence of infestation approximates 100% in healthy middle-aged or older adults.
- H pylori: This is postulated to be strongly correlated with rosacea. This is possibly due to a flush-inducing toxin present in H pylori.
- Positive family history: Some studies have shown a higher rate of positive family history of rosacea in patients with this dermatologic disorder than in skin-healthy controls.[16]
- Smoking: Some studies have shown an increased history of smoking in patients with rosacea as compared with skin-healthy controls.[16, 17]
