[What is the effect of glyceryl trinitrate on the intraocular pressure? (author's transl)]

In experiments with animals and on glaucoma patients with wide and narrow anterior chamber angle, the effect of glyceryl trinitrate on the intraocular pressure was examined. In no case was found an increase in the intraocular pressure. On the contrary the pressure fell more or less definitely in the patients within 30 minutes after application of the drug. After that the intraocular pressure increased again to the original value.
