Direct cyclophotocoagulation through minimal incision for secondary glaucoma of silicone oil eyes

Abstract

Objective To observe the clinical efficacy of direct cyclophotocoagulation through 23 G minimal incision for secondary glaucoma of silicone oil eyes. Methods A prospective study.Fourteen eyes of 14 cases with secondary glaucoma of silicone oil eyes received the application of the maximum anti-glaucoma drugs, but the intraocular pressure(IOP) weren’t controlled. They underwent direct cyclophotocoagulation through 23 G minimal incision. The IOP, complications and usage of anti-glaucoma drugs were observed at 1 day, 7 days, 1 and 3 months after treatment. Results The IOP after treatment were normal in 11 patients at every follow-up point. The IOP was increased in 3 cases at 7 days after operation and were controlled after anti-glaucoma drugs treatment. The difference of IOP was statistically significant between the pre- and post-operation (P<0.05). The complications were hyphema and severe inflammatory reaction. The difference in the number of anti-glaucoma drugs was significant between pre-and post-operation (P<0.05). Conclusion It is an effective method to control IOP by direct cyclophotocoagulation through 23 G minimal incision for intraocular hypertension after silicone oil removal.
