Association between optic disc haemorrhages in glaucoma and abnormal glucose tolerance.

Data concerning the results of glucose tolerance tests and levels of intraocular pressure were analysed for 120 patients with primary open-angle glaucoma, many of whom had been under observation for a period of four to five years. The patients consisted of two groups: in 62 patients a disc haemorrhage had been recorded at some time during the observation period, and in 58 no haemorrhages had been seen. Patients with disc haemorrhages had a higher incidence of abnormal glucose tolerance or frank diabetes and lower intraocular pressures than those without haemorrhages.
