A simple manometer for the continuous measurement of intra-ocular pressure.

THE adequate measurement of the intra-ocular pressure, both clinically and experimentally, has remained a baffling problem. The tonometer has obvious disadvantages whiclh have been summarized by Duke-Elder (1932). Chief amongst these, in the opinion of the present authors, is the possibility of self-deception, since the variations in the results of repeated determinations are often quite large ...

Normal intra-ocular pressure.

INTRA-ocuLAR pressure varies from individual to individual, from right eye to left eye, and from time to time. Many manometric studies have been made on experimental animals but observations on human eyes have been few: Wessely (1915, 1916) found an average of 22 5 and 18X5 mm. Hg, and Seidel (1922) one of 20 and 25 5 mm. Hg. Tonometric studies of human eyes, however, have been many; the result...

The Intra-Ocular Pressure of Type 2 Diabetic Patients Comparison in Diabetic Retinopathy Grades

Objective: Retinopathy is a microvascular complication of diabetes in the retina. It is hypothesized the aqueous flow decrease in patients with retinopathy which effects the Intra-ocular pressure (IOP). The purpose of this study is to determine whether a significant correlation exists between IOP and diabetic retinopathy grades. Materials and Methods: Our study is analytic cross sectional. Abo...

The Relation of Systemic Blood Pressure to Intra-Ocular Pressure

(1) High intra-ocular pressure depends upon high capillary pressure, which in turn depends upon low blood pressure. (2) Hyperpietic diathesis will predispose to an acute glaucomatous crisis in the eye. (3) Glaucoma is associated with diseases of the arterial system. (4) Venous pressure in its variations is more closely connected with the intra-ocular pressure. (5) Independent activity of capill...
