A Case of Endothelial Keratitis Associated with Immunosuppressant in Kaposi's Varicelliform Eruption

Purpose: To report a case of endothelial keratitis occurred after reactivation of herpes simplex virus following immunosuppressant therapy for Kaposi's varicelliform eruption. Case summary: A 23-year-old female was referred for ocular pain and blurred vision. She had atopic dermatitis and was diagnosed with Kaposi's varicelliform eruption on her face after using an immunosuppressant. Slit lamp examination revealed central corneal edema in the right eye. She was initially diagnosed with contact lens-induced keratitis. Subsequently, the contact lens was removed and topical antiviral agent used for prevention of ocular involvement. Four days after treatment, Wesseley immune ring of deep stromal haze and cells in the anterior chamber were present. She was diagnosed with endothelial keratitis caused by reactivation of herpes simplex virus after using an immunosuppressant. Topical steroid, hypertonic saline eye drops and cycloplegic eye drops were added to the treatment for the progression of endothelial keratitis. Corneal edema was decreased 2 weeks after treatment and anterior chamber cells decreased 1 month after treatment. There was no recurrence during the follow-up period. Conclusions: Patients diagnosed with Kaposi's varicelliform eruption after using immunosuppressants should have an ophthalmic examination to confirm ocular involvement; use of appropriate eye drops is necessary for the treatment of corneal involvement.
