Flicker defined form and RareBit measurements lack in specificity of visual pathways.

Aim: To evaluate the different visual pathways represented by the Heidelberg Engineering Perimeter flicker defined form and RareBit (magnocellular and parvocellular respectively) in different age-groups and according to the fatigue.

Methods: Totally 64 eyes of 32 healthy subjects were included in the prospective study. Each participant underwent screening-ophthalmic examination including best-corrected visual acuity, anterior and posterior segment assessment, and visual field examination with Heidelberg Edge Perimetry (HEP)-standard automated perimeter (SAP) 24-2.

[Telesensoric contact lenses - new possibilities in intraocular pressure diagnostics].

Background: Recently, on the European market, the contact lenses allowing for a 24-hour continuous measurement of intraocular pressure - Triggerfish, became available. They are designed for the diagnostics of glaucoma in adult patients. This is a unique method that allows for continuous recording of intraocular pressure, giving almost 300 readings during 24 hours.
