mild (140 to 159/90 to 99 mmhg) or moderate (160 to 179/100 to 109 mmhg) chronic arterial hypertension does not appear to cause headache. whether moderate hypertension predisposes patients to headache at all remains controversial, but there is little evidence that it does. ambulatory blood pressure monitoring in patients with mild and moderate hypertension has shown no convincing relationship b...

In eight anaesthetized, ventilated adult baboons, the intracranial volume-pressure response was examined at differing levels of raised intracranial pressure during induced changes in systemic arterial pressure and cerebral blood flow. The volume-pressure response is defined as the change in ventricular fluid pressure caused by a volume addition of 0·05 ml to the lateral ventricle. At normal int...

A total of 44 children who suffered from vernal conjunctivitis were treated with topical dexamethasone 0.1% 4 times daily for 6 weeks and tested for their intraocular pressure. There was a statistically significant difference (P less than 0.01) between the responders in our group of children and a group of normal adults reported on by Armaly in 1965.

Response to HYVET Ambulatory Blood Pressure Substudy Bursztyn et al1 speculate that our ambulatory blood pressure (ABP) participants were not representative of the whole trial. We agree this is possible but very unlikely in view of the similarity of the participant characteristics given in Table 1. As the elderly frequently nap, he wonders if this would substantially reduce daytime pressure. Ho...

The intraocular pressure response to topical betamethasone appears to be genetically determined. A study of patients with primary open-angle glaucoma, their relatives, glaucoma suspects, and volunteers shows three populations as to degree of responsiveness. It is suggested that these are the phenotypes which relate to the homozygous poor responder (nn), the heterozygous responder (ng), and the ...
