AIM: To compare the effect of diode laser transscleral cyclophotocoagulation (DL Tscpc) with cyclocryosurgery for severe glaucoma. METHODS: A total of 72 cases (72 eyes) with severe glaucoma were randomly divided into two groups. Group A (36 eyes) was treated by cyclocryosurgery using liquid carbon dioxide freezer with 6-8 spots and 60-120 seconds of every spot behind 2 mm of corneoscleral limbus of all around. Group B (36 eyes) was treated by DL Tscpc with energy power of 1.4-2.0W and laser spots of 16-36 and the pulse time of 0.5-2.0 seconds behind 1.5 mm of corneoscleral limbus of all around. Intraocular pressure (IOP), visual acuity, ocular pain symptoms and complications were observed after cyclocryosurgery and DL Tscpc. RESULTS: After 1, 7 days, 1, 3 and 6 months of followed up, the results showed that the short-term IOP between two groups had significant deviation (P < 0.05), but the long-term IOP had no statistical significance (P > 0.05). CONCLUSION: These two methods make effect in treatment of severe glaucoma including controlling IOP and relieving pain of eyes. It is concluded that DL TScpc is a simple, safe and effective therapy for eyes with severe glaucoma, but cyclocryosurgery has other fortes in treatment of corneal degeneration, corneoscleral staphyloma and inborn macrophthalmia.
