title: A comparative study of ophthalmodynamometry in hypertensive and non-hypertensive cases.
abstract: Ophthalmodynamometry was done on 100 hypertensive cases and 100 non-hypertensive cases who had clear media and no glaucoma. The ratio of the pressure mean ophthalmic: pressure mean brachial in the non-hypertensive group was 0.71:1.0, which rose to 0.78:1.0 in the hypertensive group. The ophthalmic humeral diastolic ratio increased with the severity of fundus changes. The pressure mean ophthalmic showed higher values with increasing grades of fundus changes. Those cases having a pressure mean opthalmic higher than the expected value in the hypertensive group as compared to the cases having a pressure mean ophthalmic lower than the expected value, were at a greater risk or had a graver prognosis. The importance of ophthalmodynamometry is stressed for the prognosis of hypertension along with the fundus examination.
