  • Abstract
  • Look Inside

A 66-year-old man presented with blurring of vision in his left eye since a few weeks before. A similar episode of blurring of vision had occurred 10 years before and led to the detection of deformed pupil and ocular hyper-tension. His left eye showed corneal edema, intraocular pressure of 29mmHg, and numerous pigmented iris nevi. Go-nioscopy showed peripheral anterior synechiae reaching the ring of Schwalbe over the whole circumference. His right eye was intact except for myopia. The endothelial cell count was 2,951 right and 504 cells/mm2 left. These findings led to the diagnosis of Cogan-Reese syndrome. The left eye received trabeculectomy with mitomycin C. Histopathology of excised specimen showed infiltrated intertrabecular spaces by melanophages and extreme attenuation of Schlemm's canal. There is a high possibility that elevated intraocular pressure in this syndrome is due to invasion of melano-phages into the intertrabecular spaces and attenuation or occlusion of Schlemm's canal.
