At the age of 11, he experienced a previous occurrence of raised and blister-like skin lesions. Following his recovery, a gradual formation of membranes occurred, covering both of his eyes. His right eye had light perception for visual acuity, and the intraocular pressure was determined to be soft upon examination.
