PURPOSE To evaluate the surgical outcomes in patients with Posner-Schlossman syndrome (PSS) at one year. METHODS A prospective interventional study in PSS patients with penetrating canaloplasty. Main outcome measure was success rate (6 mmHg≤ intraocular pressure (IOP) ≤ 21 mmHg) with or without medications. RESULTS Thirteen eyes in 13 patients with PSS underwent complete catheterization. The mean IOP and medications (Meds) were reduced to 16.1 ± 4.8 mmHg on 0.5 ± 1.0 Meds at 12 months. Complete and qualified success rates were 61.5% and 84.6% at 12 months. The postoperative recurrent rate of PSS was 69.2%, the mean peak IOP during attacks and episodes were decreased to 26.7 ± 8.3 mmHg and 1.7 ± 2.0 times respectively. Transient IOP spike (61.5%) and hyphema (38.5%) were the two most common postoperative complications. CONCLUSION Penetrating canaloplasty achieves a high success rate in PSS without serious complications.
