To evaluate the percentage of epithelialization in the cornea of patients with exposure keratopathy (EK) treated with the new hydrocolloid adhesive patch (smart patch).
Case report of 13 eyes of 13 patients: 6 eyes with EK due to facial paralysis and 7 eyes with EK associated with mechanical ventilation. All of the patients were treated with the smart patch, a new method to treat exposure keratopathy with an hydrocolloid adhesive patch that sticks to the upper eyelid and poliacrylic acid 4 times a day. The patch was changed every 5 days and was left for 10 ten days after full epithelialization.
Complete epithelialization was achieved in 10 patients (100% of the corneal surface) in 14 days. In 3 patients the corneal defect decreased (40% of the corneal surface) but did not healed completely and were treated with a tarsorraphy, the 3 of them had dermatochalasis. The eyelid aperture decreased 6.3 mm+- 0.95 mm in patients without dermatochalasis and 3.33mm +- 0.58 mm in patients with dermatochalasis.
Hydrocolloid adhesive patch is an alternative treatment for exposure keratopathy in patients with normal eyelid anatomy. It is a fast and reversible method for decreasing eyelid aperture. Further study is needed to determine if this method is useful in corneal ulcers of other ethiology.
