In this presentation from AAO 2015, Dr. Jeremy D. Keenan, MPH, discusses results of the Steroids for Corneal Ulcers Trial (SCUT). The results indicate that visual outcomes after steroid therapy for a bacterial ulcer depend on the timing of the medication and the type of organism. In non-Nocardia ulcers, BSCVA and scarring was significantly better in the steroid group compared to placebo. Patients who started steroid therapy earlier (within 2–3 days of commencing antibiotics) also showed better BSCVA compared to placebo, whereas those who started after 4 or more days of antibiotics showed worse vision.
