We examined the relationship of intraocular pressure and the development of one-kidney, one wrapped (perinephritic) hypertension in the dog. Conscious femoral arterial pressure (direct arterial puncture) and intraocular pressure (Schiotz tonometer) were measured weekly before and after the surgical induction of hypertension in 11 healthy male mongrel dogs and before and after unilateral nephrec...

This paper discusses the method of establishing that no hazard of increased intra-ocular pressure is incurred from the elevated carbon dioxide content of the sealed submarine atmosphere. The reasons for suspecting a possible intra-ocular pressure rise under such conditions are presented. The serial tonometry readings, both under control conditions and at elevated ambient carbon dioxide levels w...

A Schi0tz Pi calibration by open manometer was performed on 18 owl monkey eyes cannulated in situ. Pi values for the owl monkey corresponded closely to those of the 1955 Friedenwald nomogram. The average ocular rigidity measured in 16 additional eyes with the use of clinical techniques was 0.0173 (± 0.0015). A manometric calibration for a 4 mm. diameter applanation face was done similarly on 21...

THE occurrence of glaucoma in an eye after irradiation has been the subject of few reports. It is proposed to review briefly those cases that have been described and to present another with its own peculiar features. Birch-Hirschfeld (1921a, b) reported a case of a man aged 61 who received radiotherapy for a wart on the right upper lid. The conjunctiva became thickened and its vessels dilated a...

A housewife aged 44 complained of bilateral dimness of vision of one week's duration at the time of reporting for treatment in May, 1957. Some photophobia and ocular discomfort were also present. There was no history of antecedent disease. Her teeth were septic and she had experienced joint pains on and off and more recently a constant severe headache. Examination.-An anterior uveitis affected ...

introduction: cataract is an opacified lens and senile cataract is a common disorder. it is desirable to reduce intraocular pressure (iop) in order to minimize intra and post operative difficulties and complications. many researches have studied the effects of muscle relaxants on iop. comparison effect of atracurium and pancuronium on iop has been evaluated in one study with a small sample size...

The objective of the study was to evaluate the antiglaucoma effect of calcium channel blockers diltiazem and verapamil. Albino rabbits were used and chronic glaucoma was induced in them using freshly prepared 150 units of alphachymotrypsin. 0.1 mL of drug solution was administered topically into the left eye whereas the right served as control. The pressure recording was carried out at 15, 30, ...
