AIM: To compare the surgical effect between transscleral cyclophotocoagulation and cyclocryotherapy for neovascular glaucoma. METHODS: In 2006 from January to December, 38 cases (43 eyes) diagnosed with neovascular glaucoma were treated. 18 cases (18 eyes) were treated with cyclocryotherapy and 20 cases (25 eyes) were treated with transscleral cyclophotocoagulation. The post-surgery clinical procedure was no diffrence between two groups. The intraocular pressure (IOP), eyesight, the clinical procedure, and the complications after surgery were observed. RESULTS: During follow-up of 3 months, the IOP of 11 eyes(61%) was controlled from 11 mmHg to 24 mmHg in the cases treated with cyclocryotherapy, and 20 eyes (80%) in the cases treated with cyclophotocoagulation respectively. In each group, there was highly statistical difference between the IOP of pre-operation and postoperation(P = 0.000). And there was no statistical difference between the post-operation IOP of two groups(P = 0.669). The visual acuity of 10 eyes (56%) was preserved in the cases treated with cyclocryotherapy, and 21 eyes(84%) in the cases treated with cyclophotocongulation respectively, the result was statistically different(P = 0.040). Postoperative complications were found fewer in the cases treated with cyclophotocoagulation, included hypema, pain, anterior chamber haemorrhage, and aqueous flare. CONCLUSION: To controll the IOP of eyes with neovascular glaucoma, transscleral cyclophotocoagulation and cyclocryotherapy are both effective and safe. Furthermore, cyclophotocoagulation has fewer postoperative complications and pain, it also has higher visual acuity preservation. LA: Chinese
