Stellate ganglion block was performed in 15 patients with intractable glaucoma by injection of 8 ml of 1y lidocaine. The followings are the changes of intraocular pressure(mmHg): Pre -block $32.26{pm}4.44$ 10 minutes after block $36.80{pm}4.60$ 20 minutes after block $32.61{pm}4.41$ 30 minutes after block $28.87{pm}4.30$ 60 minutes after block $24.73{pm}4.37$ 120 minutes after block $26.87{pm}3.18$ 180 minutes after block $31.40{pm}3.76$ The pressure rose up to 10 minutes post block and significant pressure descent was noticed from 30 minutes post-block. Maximum descent was seen by 60 minutes post-block and pre-block pressure was restored by 180 minutes post-block. For the purpose of cheeking the treatment effect, similar blocks were performed in 15 patients, one time daily for 5~8 days 3 times every othor day.
