The effects of hyperbaric oxygen on visual functions in ischaemic optic neuropathy.

The effects of hyperbaric oxygen therapy were studied in nine patients with non-arteritic anterior ischaemic optic neuropathy, who had been unsatisfactorily treated with corticosteroids. In four patients with signs of optic disc atrophy there was no improvement of visual functions after hyperbaric oxygen treatment, whereas in the other five patients, who had no signs of optic disc atrophy, visual acuity and visual field improved. The achieved improvements were maintained at a control examination six months later.

Cardiovascular reflex testing and pupil cycle time in open-angle glaucoma.

The aim of the study is to assess the value of function tests of the autonomic nervous system in open-angle glaucoma by testing the cardiovascular reflexes and pupil cycle time. The experimental group consisted of 19 glaucoma subjects with controlled intraocular pressure. The control group consisted of 20 healthy volunteers.
