  • Look Inside

 Laser iridotomy was performed for narrow angle in both eyes of a 58-year-old woman. Bullous keratopathy was present in her right eye when seen again 8 years later. Both eyes had shallow anterior chamber with pupil block. The corneal endothelial cell population was 407/mm2right and 644/mm2left. We performed cataract surgery and intraocular lens implantation 4months later. Corneal edema disappeared 3months later. The corneal endothelial cells have stabilized during 4 years and 6months of follow up. Ten years after the initial laser iridotomy,her left eye developed bullous keratopathy with the corneal endothelial cells reduced to 250/mm2. Corneal edema disappeared 3months after cataract surgery. Two years after surgery,the corneal endothelial cells had increased to 380/mm2. This case illustrates that cataract surgery may induce stabilization of corneal endothelial loss secondary to laser iridotomy. Aqueous flow into the anterior chamber through the site of iridotomy and not through the pupil seemed to be the cause of observed loss of corneal endothelial cells.
