Cyclophotocoagulation with the transscleral contact neodymium: YAG laser versus cyclocryotherapy in rabbits

Ophthalmic Surg. 1991 Jan;22(1):27-30.


Either transscleral cyclophotocoagulation with the contact neodymium:YAG (Nd:YAG) laser or cyclocryotherapy (CCT) was performed in rabbits to compare the efficacy of these procedures in reducing intraocular pressure (IOP) as well as the histologic changes they induced. The difference in mean maximum reduction of IOP in the two groups was statistically insignificant, but the Nd:YAG laser irradiation, using 2.5 J, destroyed less tissue than the CCT.
