William Trattler, MD, joins Sila Bal, MD, MPH, to discuss a case of a 31-year-old woman who presented with pain and decreased vision in her right eye. Slit lamp examination revealed conjunctival injection and a unifocal area of stromal haze with no epithelial defects. Dr. Trattler explains further diagnostic strategies for this case to help determine the best treatment. He also reviews approaches to suppress inflammation in different forms of keratitis.
