Abstract：Objective To observe the effect of 810 nm laser trans-scleral cyclophotocoagulation (TSCP) on the intraocular pressure (IOP) of patients with refractory glaucoma.Methods The clinical data of 78 patients (78 eyes) with refractory glaucoma treated with 810 nm laser TSCP in our hospital between April 2014 and June 2016 was analyzed retrospectively. The changes of visual acuity and IOP after surgery were recorded. The degree of eye pain after surgery was observed, and the incidence of related complications was statistically analyzed.Results (1)The success rate of 810nm laser TSCP in 78 patients with refractory glaucoma was 93.59%. (2)1 day after surgery, visual acuity declined in 13 cases, and 1 week after surgery, the number of cases decreased to 11.6 months after surgery, the percentages of patients with unchanged visual acuity, those with improved visual acuity and of patients with decreased visual acuity were 74.36%, 15.38% and 10.26%, respectively. (3)The IOP of patients decreased obviously at 1 day, 1 week, 1 month, 3 months and 6 months after surgery (P<0.05). 1 month, 3 months and 6 months after surgery, IOP of the patients tended to be stable, and was lower than that at 1 day after surgery (P<0.05). (4)VAS scores decreased at different time points after surgery. The scores tended to be stable one to 6 months after surgery and were significantly lower than those at 1 day and 1 week after surgery (P<0.05). (5)The main complication of patients was eye pain, mild inflammation of the anterior chamber was the main complication soon after surgery, and the main complications long after surgery included cataract, atrophy of eyeballs and uveitis.Conclusions TSCP can reduce IOP and relieve eye pain in patients with refractory glaucoma. The incidence of complications is low and safety can be ensured.
