Purpose: To assess the efficacy and safety of Gonioscopy Assisted Transluminal Trabeculotomy (GATT) in the treatment of glaucomatocyclitic crisis (Posner-Schlossman syndrome).

Materials and methods: We retrospectively reviewed six patients diagnosed with glaucomatocyclitic crisis and uncontrolled Intraocular Pressure (IOP) who underwent Gonioscopy Assisted Transluminal Trabeculotomy (GATT). ALL the patients were followed-up for 12 months after the surgery. Clinical outcome measurements included visual acuity, intraocular pressure, complications and relapses.

Results: Mean IOP before GATT was 31.17 mmHg ± 7.08 mmHg (range 23 mmHg-41 mmHg). The mean number of anti-glaucoma medication prior to surgery was 2.50 ± 0.55. By the last follow-up, IOP in 5 patients was reduced to normal level (15.40 mmHg ± 2.97 mmHg) and their anti-glaucoma medication was decreased prominently to 0.80 ± 0.84. Only 1 of the patients with a 30-year history of Posner-Schlossman Syndrome (PSS) underwent trabeculectomy at 8 months after GATT. The mean percentage of IOP decrease in 5 patients at 12 months was 44.29%. Recurring attack of glaucomatocyclitic crisis occurred in 3 patients during the follow-up period; nonetheless the peak IOP and the duration of the Elevated Intraocular Pressure (EIOP) were reduced after the surgery.

Conclusion: GATT seems to be a reliable and effective method for the management of glaucomatocyclitic crisis with uncontrolled IOP. Although it may not prevent relapses of glaucomatocyclitic crisis, there is a chance that it may lower the peak IOP and the duration of the EIOP in the relapse.
