[The effect of neural mediation on the immediate rise in intraocular pressure in glaucomatous eyes after cyclocryotherapy (author's transl)].

As a rule, there is a transient rise in intraocular pressure following cyclocryotherapy. The preoperative administration of retrobulbar anaesthesia to a group of patients significantly reduced intraocular pressure after cyclocryotherapy in this group as compared with a control group without anaesthesia. These results imply that the temporary rise in intraocular pressure after cyclocryotherapy is mediated by a neural pathway.
