PURPOSE: To observe the changes in ciliary processes in endoscopic cyclophotocoagulation, and propose the principle for choosing energy of laser and access of operating.
METHODS: Endoscopic cyclophotocoagulation was performed in the human eyes donated for corneal transplantation through the limber or the pars plana. The coagulated tissue was checked histologically.
RESULTS: The ciliary body was viewed clearly with the endoscope (E2). The best choice of energy was shuthe range from 0.4 W to 0.6W, and the most effective reaction was that the processes turned to be pale and shrunk. The main histopathologic changes were that the normal structure of ciliary body was destructed, the pigment epithelial cells and stroma degenerated and the no-pigment epithelial cells kept intact.
CONCLUSION: Cyclophotocoagulation could be completed accurately visually under the endoscope. The principle of lowering intraocular pressure was the destruction of ciliary stroma and ciliary pigment epithelial cells.
