[Variations in intraocular pressure in normal-pressure glaucoma and in hypertensive open-angle glaucoma].

The comparative study of the intraocular pressure variations at patients with low-tension glaucoma and hypertensive open-angle glaucoma reveals some common modifications regarding the aspect of the nictemeral levels of intraocular tension (the maximal variation of the nictemeral curve, the time of maximal intraocular pressure, variability) and the aspect of the provocative testes. The nictemeral curves and the provocative testes are used at the patients suspects of low-tension glaucoma both for diagnose and to eliminate the incipient open-angle glaucoma with one tensional pick.
