Ocular rosacea is associated with a chronic skin condition known as acne rosacea. The problem usually affects those with light skin, and is characterized by redness and bumps concentrated on the forehead, nose and cheeks. One of the earliest symptoms of rosacea (often experienced during puberty) is facial flushing brought on by changes in body temperature, emotion, or hot drinks. Eventually, the skin may become chronically red, irritated and inflamed.
Approximately 60% of patients with rosacea develop related problems affecting the eye (ocular rosacea). Patients with ocular rosacea most commonly experience irritation of the lids and eye, occurring when the oil-producing glands of the lids become obstructed. Styes, blepharitis, episcleritis, and chronically red eyes are also typical conditions. Ocular rosacea may also affect the cornea, causing neovascularization (abnormal blood vessel growth), infections, and occasionally ulcers.
