Abstract
Bacterial keratitis can cause significant morbidity from ulceration of the cornea and the resultant scarring. The use of steroids to decrease these complications is controversial with arguments for and against their use. The SCUT (Steroids for Corneal Ulcers Trial) was initiated in 2006 to definitively determine whether steroids in bacterial keratitis were beneficial or harmful. While the SCUT showed no benefit or harm overall, subgroup analyses showed that larger, more central ulcers with very poor initial visual acuity may benefit. On the other hand, Nocardia ulcers that were treated with steroids had worse outcomes. The study did have some limitations as the patient population was not typical for bacterial keratitis in the United States, and there were some criticisms of the therapeutic approach so the question is still not definitively answered.
