Abstract
Objective:
To present a case of closed-angle glaucoma due to Plateau iris syndrome.
Case Description:
Female Patient, 50 years old, that 13 months ago was treated for primary angular closure to the left successfully with iridotomy with Nd: YAG Laser. She attended the service complaining of visual haze and intermittent pain in the left eye. On examination, it was observed angle closure in the left that could be openned with identation. Intraocular pressure (IOP) of 16 and 42mmHg respectively. The examination of the anterior chamber angle by optical coherence tomography showed patent iridotomy in both eyes and on the left the apositional angle closure. By studying the angle images it was possible to identify plaeau iris configuration, characterizing the iris syndrome of plateau iris. Gonioplasty with argon laser was performed in both eyes, which allowed the correction of iris configuration and control of IOP. After treatment, visual field examination was performed, which was normal to the right and to the left identified superior arcuate scotoma. The Fundus showed a normal right optical disc (0.2), and glaucomatous left (0.6). One year after gonioplasty, visual acuity was 20/30 without correction by both eyes, PIO of 12 and 13mmHg, without medications, with unaltered visual fields and optic discs.
Conclusion:
The Iris configuration in Plateau should always be considered in front of cases of primary angle closure, being the optical coherence tomography valuable tool to corroborate in its diagnosis.
