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.

Although there have been few direct observations, the etiology of spontaneous hyphema in patients with retinal or ocular hypoxia is assumed to be hemorrhage from a neovascular iris vessel. This paper reports observed hemorrhage from such a rubeotic iris in a patient with central retinal vein occlusion, diabetes, hypertension, peripheral vascular disease and chronic open-angle glaucoma. Bleeding was spontaneous with dilation, but stopped within 24 hours without treatment, leaving only traces of inferior angle blood staining. The two types of central retinal vein occlusion, and suggestions for their management, are also discussed.

Are the ocular hypertension and glaucoma two different clinical entities? Recent researches show that ocular hypertension can have an evolution period, of about five years, without clinical manifestations of glaucoma. In ocular hypertension, the atrophy of the retinal nerve precedes with many years the appearance of the perimetric deficits. Retinographies in non-erythro light show a destruction, up to 40%, of the nerve fibres of the retina without evident perimetric modifications. The conclusion is reached that intraocular hypertension is only an incipient stage of a glaucoma not yet detected by the clinical means available.

An elderly man with glaucoma and acute onset of left-sided cranial nerve III, V, and VII palsies was found to have associated marked intracranial artery dolichoectasia. Dolichoectasia (arterial elongation and distension) affects the intracranial arteries, producing various neurological and ophthalmological findings. The patients are usually men who are more than 40 years old and have a history of hypertension. Diagnosis is made by characteristic radiologic findings. In patients with neurologic symptoms and signs suggesting a space-occupying mass, intracranial dolichoectasia should be considered.

We studied the frequency of massive suprachoroidal hemorrhage during and after penetrating keratoplasty. Nine cases of intraoperative or immediately postoperative massive suprachoroidal hemorrhage were identified in 830 consecutive patients (1.08%) undergoing penetrating keratoplasties at the Manhattan Eye, Ear, and Throat Hospital over a 2 1/2-year period. Six of the nine patients had atherosclerotic disease or hypertension, six of nine patients had glaucoma, and eight of nine patients had undergone previous intraocular surgery. Surgery was performed under general anesthesia in 714 patients, and four of these patients (0.56%) suffered hemorrhages. Five of 116 (4.3%) local anesthesia patients experienced expulsive choroidal hemorrhage. The increased resistance to venous outflow associated with retrobulbar anesthetic injection may significantly contribute to the risk of massive suprachoroidal hemorrhage.

Oculo-oscillodynamography after Ulrich was performed in 27 patients suffering from glaucoma without hypertension (so-called low-tension glaucoma). Patients who had severe systemic disease or were receiving systemic medication which might influence IOP, and patients with narrow angle and an IOP higher than 22 mm Hg were excluded. In 85% of the patients a severe decrease in systolic ciliary perfusion pressure was found, whereas the systolic retinal and diastolic ocular perfusion pressures were significantly lower in almost 30% of the cases. Glaucoma without hypertension appears to be caused by the vascular change at the disk.

A 65-year-old man with hypertension and glaucoma developed diuretic-induced hypokalaemia complicated by torsade de pointes ventricular tachycardia. This arrhythmia requires accurate recognition so that appropriate therapy may be administered. When torsade de pointes is diagnosed, a careful search for underlying causes should be conducted as reversal of these may prove curative, as in this case.

Atenolol is a newer betablocker, widely used as an antihypertensive drug. It cause a large and rapid fall in IOP when used orally and topically. A total of 33 patients both having normal and raised IOP were included in the study. The drug was given in a dose of 50 mg. tab. orally once a day for 7 days at 8 A.M. and IOP recorded after 24 hours, 72 hours and on 7th day. It produces significant and sustained fall in IOP in both normal and raised IOP patients besides lowering of systematic B.P. and pulse rate. The IOP on patients with systemic hypertension with Atenolol will be reduced and stoppage of therapy may cause glaucoma damage.

Measurements of the true tolerant intraocular pressure (IOP) in 500 eyes of 384 patients with primary glaucoma and in 26 eyes of 13 patients with ophthalmic hypertension have demonstrated that the value of the true tolerant 10P is close to the lowest border of the mean statistical range of normal ophthalmic tone values, this value being, on an average, 13.4 mm Hg in primary glaucoma and 10.2 mm Hg in low-pressure glaucoma, whereas in ophthalmic hypertension it has been much higher - 24.8 mm Hg. The intolerance index in stabilized glaucoma does not surpass 4 mm Hg with both the true and the tonometric 10P.

The prevalence of open-angle glaucoma is believed to be very high among West Indian blacks. To begin investigating the prevalence and risk factors for glaucoma and other eye diseases in Barbados, WI, a pilot study was conducted. The pilot project identified a stratified, random national sample of 300 persons over 35 years of age who were invited to participate in an ophthalmic examination and an interview. Of those contacted 89% were eligible and 95% of these agreed to participate. The overall glaucoma prevalence in the participants was 6%; it was 13% among black and mixed persons over 54 years. Age related cataract, hypertension, and diabetes were frequent findings. Although the sample size of the pilot project is small, the results suggest a high prevalence of glaucoma in Barbados, a finding that merits further study.
