A man in his early 80s underwent penetrating keratoplasty for leucomatous corneal opacity in his left eye. Postoperative slitlamp biomicroscopy results revealed a clear corneal graft with a retrocorneal membrane that could be traced clearly up to the graft-host junction (Figure, A). A clinical diagnosis of a detached Descemet layer of the donor graft was made. Anterior segment optical coherence tomography results revealed a hyperreflective linear undulating structure in the anterior chamber that was in continuation with the posterior lips of the host cornea (Figure, B). This was suggestive of a retained host Descemet membrane that might have resulted from an incomplete trephination of the host cornea. The patient was kept under observation, as the graft was clear.
