[Study of circadian (diurnal) rhythm of intraocular pressure in healthy persons and patients with glaucoma]. / Issledovanie tsirkadiannoi (okolosutochnoi) ritmiki vnutriglaznogo davleniia v norme i u bol'nykh glaukomoi.

35 patients (65 eyes) were examined; 10 patients (18 eyes) were without glaucoma or ophthalmic hypertension, and 25 patients (47 eyes) had an open-angle glaucoma of stages I-III. Glaucomatous patients were divided into 2 groups: patients of one group were examined in hospital (26 clinical studies), and those of another group were examined in policlinics (21 clinical studies). The studies resulted in elaborating a nearly daily rhythm correlating with the modern chronological-and-biological recommendations, i.e. 9 measurements during 4 days were made in hospital and 11 measurements during 5 days were made in policlinics. Such tonometry method was proven to have advantages before Maslennikov's daily tonometry. It was established that the cyclic nature of fluctuations of intraocular pressure (IOP) is individual not only for each person but also for each eye. The obtained data support the advisability of measuring the IOP by using the chronological-and-biological method in diagnostically complicated situations, at so-called glaucoma with pseudo-normal IOP, and in choosing the treatment schemes for patients with glaucoma.
