The authors have studied on the effect of digital pressure on eyeball under the surface anesthesia instead of other reducing agents of intraocular pressure and retrobulbar anesthesia in order to lower the intraocular pressure as a preoperative procedure of cataract extraction in 26 eyeballs of 24 patients and following results were obtained: 1. The authors had intraocular pressure lowered till averaging 10.8 mmHg (average 13.5 ~ 8.0 mmHg) of original pressure by ocular massage. 2. Massage on eyeball was thought to be a satisfactory preoperative procedure to perform cataract extractIon. 3. In operative complications, loss of vitreous and rupture of capsule were noticed 11.5% and 60% respectively. and it was thought to be caused by technical failure in surgeons. In view of this fact we could not find that the loss of vitreous was caused by intraocular pressure below 13.5 mmHg.

One hundred and eight cases who had Sr(90) irradiation in preventing pterygium recurrence were studied. The average follow up period in this series was more than one year and maximum of 3 years. The following results were obtained. 1. Three pterygium recurrences out of 11 cases (27.3%) were found in group of 1200 rads and one out of 9 (11%) in 1800 rads group. These recurrent cases did not have enough amount of irradition due to patient's conditions. No pterygium recurrences were observed in 88 cases of 2400, 3000, 3600, and 4200 rads groups. We think that the amount of post irradiation for prevnting recurrence is more than 2400 rads. Subacute reaction of post irradiation occurred in 3000, 3600, and 4200 rads groups; 7 cases out of 76 cases (9.2%). Our cases have not been followed long enough to rule out late complications, especially radiation cataract and telangiectasis of conjunctival vessels. No late complications, however, have been found up to three years after Sr(90) irradiatron. 3. Post irradiative medication of hydrocortisone eye drops (0.5% qid) was continued from immediately after irradiation to 3 days after last irradiation. The application of hydrocortisone eye drops seems to decrease the rate, mitigate the symptoms, and shorten the duration of treatment of transient and subacute reactions.

There have been some case reports of the coexitence of extraadrenal pheochromocytoma and renal artery stenosis. Some reporters proposed that their coexistence may be associated through a common pathophysiological mechanism mediated by catecholamine secretion. Also some noted that trasient renal artery stenosis due to a spasm was induced by the catecholamines released from pheochromacytoma. We report a case of left paraaortic extraadrenal pheochromacytoma that had a transient oral captopril test positive result. After 5 days alpha-antagonist reduced the vasospastic response of catecholamines. After surgical removal of the tumor, plasma catecholamines and urinary vanillymandelic acid concentrations as well as the blood pressure level, were restored to normal.
