Methods: Retrospective study. 64 eyes of 60 patients who underwent cyclophotocoagulation between January 2008 and March 2014. Evaluation of the pre- and post-operative intraocular pressure, the control of ocular pain, the number of anti-glaucoma drugs used in pre- and post-intervention, the rate of complications and the success rate. Results: There was an overall success rate of 81.3%, with 9 eyes needing a second intervention. There was a mean reduction of 52.6% of the preoperative mean intraocular pressure of 41.25 to 19.56 mmHg at 12 months observation (p < 0.001). There was also a statistically significant reduction in the number of anti-glaucoma drugs used from 3.19 to 2.01 per eye and the resolution of pain in 75% of patients. Conclusions: cyclophotocoagulation is an effective procedure, with an expected positive impact on quality of life of patients as a result from the decreased number of anti-glaucoma drugs, sustained intraocular pressure reduction and resolution of pain.展开更多

Eighteen eyes of 18 patients were treated with UCP second-generation probes(Eye OP1). After treatment, the mean intraocular pressure(IOP) significantly decreased from 26.8±7.2 to 18.8±6.1 mm Hg at day 1 and to 14.7±3.4 mm Hg at month 6(all P<0.001). Mean laser flare-cell photometry value steeply increased after surgery from 12.1±7.5 to 64.1±53.9 ph/ms(P=0.001) at day 1, and then progressively decreased to respectively 60.6±49.7 at day 7, 43.5±38.5 at day 14 and 28.2±18.3 at month 1(all P<0.05), returning at levels similar to baseline ones at month 3 and month 6(respectively 16.7±6.2 and 12.8±10.2, both P>0.05). A significant negative correlation was found between postoperative increase of aqueous flare values and anterior chamber depth(R=-0.568, P=0.014). This timeframe may be considered reasonable for repeating UCP treatment, when required.展开更多
