Studies on the Retinal Artery Pressure in Hyprtensive Patients

Part 2. Correlation of the Retinal Artery Pressure to the systemic Blood Pressure in Hypertensive Patients

Abstract

In part 1, Hypertensive patients were divided into 3 groups A, B, and C, according to the relation between the retinal artery pressure and the systemic blood pressure.
It is generally accepted that the ratio of the retinal to the systemic blood pressure is about 50%. This ratio, however, should be corrected in regards to the subject or factors involved in the measurement of the systemic blood pressure.
In group B, when subjects with the systemic blood pressure range 150 to 180 mm of mercury, the ratio of the retinal to the systemic is found almost to be 50%.
However, the systemic pressure of under 150mm changes the ratio higher than 50%, while with pressure over 200mm of mercury the ratio proves to be lower than 50%.
