Klinische Methoden der Untersuchung des intraokularen Druckes und der Abflußverhältnisse beim primären Glaukom

Routine Tonometry in Ophthalmic Practice

“…This holds good when the pressure measurements are carried through under uniform external conditions. The unexpected result in the present study is, perhaps, due to the measurements having not taken place under uniform external conditions, the 24-hour measurements having been performed during stay in hospital, where the tension might be expected to fall to a lower level than when the patient is in his usual environment (Hager 1958, Goldmann 1960, Ourgaud & Etienne 1961, Katavisto 1964.…”

Routine Tonometry in Ophthalmic Practice

“…I n assessing the course in the treated patients we must bear in mind that, of course, the treatment can only be expected to have effect if it really does bring about a fall of the pressure. A regulation to below 20 mm H g is supposed to be required (Weekers et al 1959, Goldmann 1960, Lawaetz 1960, Touvinen 1961, Leydhecker 1963, Shaffer 1967, Sugar 1969).…”

“…It has, however, been noticed often to be difficult to obtain a fall in eyes with a pressure level about 25 mm Hg, which, in fact, will predominate among patients traced on examinations for revealing glaucoma (Goldmann 1960, Walker 1966, Leopold 1967.…”

“…If we may be justified in drawing certain conclusions on this basis, it seems that choice of 21 mm H g as the screening level may be permissible. This has, in fact, often been indicated as an appropriate screening level when applanation tonometry is employed (Goldmann 1960, Schmidt 1960, Becker S: Shaffer 1965, Chandler 1965, Leopold 1967, Pollack 1967.…”
