What caused this problem?
Our patient had corneal destruction from chronic methamphetamine use. This resulted in descemetoceles ( outpouching of the inner layer of the cornea). Drug induced ocular symptoms also include retinal vasculitis, episcleritis, panophthalmitis, endophthalmitis, scleritis, and globe rupture.
In the initial stages of chemical eye burns irrigation and correction of the pH to between 7.0 and 7.2 should be accomplished. Fluorescein staining may be absent with a complete epithelial defect. In mild burns a topical steroid is applied four times a day for one week to control inflammation. A cycloplegic is also given three times per day. In more severe burns prednisolone is given q 1 hr while awake and tapered rapidly between days 10 and 14 to minimize the risk of corneal melting. Amniotic membrane is often used to cover the cornea in severe burns. In some cases limbal stem cell transplants are performed from the contralateral eye.
Our patient will be receiving a corneal transplant.
