If, because of too high an intraocular pressure, a damage to the visual nerve has occurred (glaucoma), there are two fundamental alternative methods to lower the intraocular pressure:
| - |
by improving the intraocular circulation of eyewater and its drainage out of the eye either by a fenestration of the iris (iridectomy) alone or in conjunction with the construction of an overflow-valve into the wall of the eye (trabeculectomy). |
|
| - |
by ablation of the ciliary body and thus reduction of the eyewater-production by either laser beams (cyclophotocoagulation) or freezing (cyclocryocoagulation).
|
The choice of the surgical procedure depends on the respective findings and any accompanying diseases of the eye.
