Case 3 had previously undergone a penetrating keratoplasty with tarsorrhaphy for a progressive ulcer and descemetocele caused by herpes zoster ophthalmicus on the left eye. He developed a recurrent herpes zoster with epithelial dendrites and ulcers stained with rose bengal (A) and fluorescein (B), and progressed into disciform and necrotising stromal keratitis. This was complicated by bacterial keratitis, and a large inferior one third hypopyon (C). Following appropriate antibiotics and aciclovir, the sterilised ulcer became thin in several locations of the cornea. Amniotic membrane transplantation was performed and resulted in total healing of the ulcer with a quiet ocular surface in 13 days (D and E). After the corneal surface had been stable for 15 months (F), a repeat PKP was performed and covered with an amniotic membrane as a patch, which was dissolved in 2 weeks, and the graft showed a smooth surface and clear stroma 8 months later (G and H).
