Contact Lens Update

Contact lens induced peripheral ulcer.
A circular, well circumscribed, dense, yellowish-white, focal corneal infiltrate (0.2-2.0mm in diameter) located in the peripheral to mid-peripheral cornea. It is always located in the anterior stroma and has a complete loss of overlying epithelium. Symptoms can vary, but may include pain or soreness, irritation and watering. The condition is almost always unilateral, consisting of a single lesion. Prognosis for healing is good. Typically the CLPU resolves to a circular, anterior stromal scar which persists for more than 6 months after the event. Some patients may not present with an “active” CLPU and the only evidence of the event may be the presence of the resulting scar.
