Abstract Details


To describe a report and case of a 52-year-old woman referred to the ophthalmology department at the Federal Hospital of Bonsucesso with an iridoschisis associated with closed-angle glaucoma and unilateral corneal failure. Iridoschisis is a rare disorder characterized by the separation of the anterior stroma from the posterior stroma iris and muscular layers. The anterior layer forms free fibers that keep floating in the anterior chamber.


Federal Hospital of Bonsucesso


For the treatment of closed-angle glaucoma, we chose to perform iridotomy in the right eye (without corneal failure) and for clinical treatment we started instillation of eye drops with the combination of 2% dorzolamide and 0.2% brimonidine tartrate in both eyes 2 times a day. In the left eye (with corneal failure) we indicated a corneal penetrating transplant. For the right eye, argon-laser photocoagulation of the free fibers of the irirs was performed in contact with the corneal endothelium in an attempt to avoid the failure of this layer.


Regarding intraocular pressure, we observed a decrease of 6 mmhg in right eye and left eye did not achieve the follow-up of intraocular pressure because of corneal failure. In the right eye, up to the present moment we did not observe signs of corneal endothelial failure nor alteration in specular microscopy. Regarding the left eye, we referred the patient to the national row for corneal transplantation.


Idoschisis is a condition that affects the age range between 50 and 70 years and is very often associated with closed angle glaucoma and sometimes corneal decompensation. It is necessary to accompany these patients with periodic consultation to avoid corneal decompensation and progression of possible cases of glaucoma.
