Course: Anterior Chamber Snowflake After Keratoplasty

CME Credits: 1.00

Released: 2023-12-14

A 62-year-old woman presented with painless vision reduction and eye redness in the right eye for a week. The initial best-corrected visual acuity (BCVA) was 4/20 (approximately 20/100), and an irregular superficial corneal ulcer with an epithelial defect size of 3 mm?×-5 mm was found in the center of edematous cornea. She received penetrating keratoplasty 4 months later, as the ulcer did not heal with intensive medication. Then, topical tobramycin dexamethasone, topical tacrolimus, and daily oral prednisone, 40 mg, were prescribed, with a gradual taper of prednisone to a maintenance dose of 10 mg.
