title: Transient reversible cupping in juvenile-onset glaucoma.
abstract: A 17-year-old man had marked glaucomatous cupping of his left optic nerve. Two days after trabeculectomy, the appearance of the disk changed dramatically, appearing full, rather than cupped. Over the next month, with normal intraocular pressure, the optic nerve resumed its preoperative excavated appearance.
