peer reviewed / The state of retinal adaptation can alter the posilion of the isopleres considerably if these are measured in reduced illumination (less than 30 Lux); if the campimeler gels normal light, this is unimportant. During reduced illumination one finds a progressive increase in the field of vision, this is an excellent test for the adapta...
peer reviewed / The description of a new apparatus for clinical research on the frequency of fusion with intermittent light stimuli. The object tested can be placed in any point in the field of vision, whereas the fixation point remains the same. One can, therefore, discover the relationship between the results of the quantitative perimetry and the...

1. The authors use an “electronic tonometer”, which consists of a combination of Schiøtz’s apparatus with an electric installation. In use, the tonometer shows continuously and graphically the differences in tension, similarly to the electro-cardiogram. During 5 min. in which the tonometer was placed on the cornea, they measured the slackening of t...
peer reviewed / 1. The authors use a test described in former works on the compression of the bulbus in chronic glaucoma. 2. They find an increase of resistance to the flow of acqueous humour and a comparison between the decree of increase and the flow. They deduct that the increase of resistance and the intraocular hypertension are causally bound ...
peer reviewed / Pilocarpine modifies neither the flow of the aqueous humour, nor the episcleral venous pressure, but it diminishes the resistance to the aqueous flow in the glaucomatous eye. This fact seems to result from either the stretching of the corneoscleral trabeculum by the contraction of the ciliary muscle, or the vasodilatation of the int...
