Effects of Freezing of the Ciliary Ganglion in Absolute Glaucoma

The resuIts of cryotherapy of the ciliary ganglion in absolute glaucoma are presented. The air cases had been suffered from severe ocular pain, headache without vision. The tip of the cryoapplicator (2.5mm in diameter, retinal probe, Amoils Cryo Unit) at a temperature between -60 degrees C to -70 degrees C was applied to the ciliary ganglion site for 30 seconds four to five times at one time. Edema of lids and conjunctiva occurred in all three cases except a case without lid edema and subsided in 5 days. All cases could spend life without pills for pain even though the tension was not decreased to normal leveI. The observation course was between 14 and 90 days.
