TT is a 57-year-old commercial pilot with a history of high myopia. His right eye had suffered penetrating trauma a number of years ago that had been successfully repaired by repair of a corneal laceration and removal of a cataractous lens with implantation of an intraocular lens. He presented to his ophthalmologist with complaints of flickering lights and a shadow in the upper part of his right visual field. Examination found best corrected vision in that eye of 20/20-2. The anterior segment was unremarkable by slit-lamp examination except for an old inferior corneal scar with iris to the cornea. The fundus appeared normal by ophthalmoscopy. He was referred to a neuro-ophthalmologist, who could not find a cause for the symptoms. He returned to his primary ophthalmologist, who performed echography.
