Gonioscopy and artefacts.

Gonioscopy and tonography in glaucomatocyclitic crises.

(1) The condition is unilateral. (2) The eye remains white or at most only slightly congested during an attack. (3) Subjective symptoms are minimal and vision is usually not impaired to any degree. (4) Signs of cyclitis do not precede the glaucoma; posterior synechiae are never formed. (5) Attacks may last from a few hours to a month, but rarely more than 2 weeks. (6) Between attacks the eye sh...

The effect of Gonioscopy on keratometry and corneal surface topography

BACKGROUND Biometric procedures such as keratometry performed shortly after contact procedures like gonioscopy and applanation tonometry could affect the validity of the measurement. This study was conducted to understand the short-term effect of gonioscopy on corneal curvature measurements and surface topography based Simulated Keratometry and whether this would alter the power of an intraocul...

Agreement between gonioscopy and ultrasound biomicroscopy in detecting iridotrabecular apposition.

OBJECTIVE To assess the agreement between findings obtained at dark-room gonioscopy and ultrasound biomicroscopy (UBM) in the diagnosis of iridotrabecular apposition in light and dark conditions. METHODS We enrolled patients with appositional angle closure at dark-room gonioscopy performed using a 1-mm slitlamp beam that did not cross the pupil. Ultrasound biomicroscopic images were acquired ...

Artefacts and Family Resemblance

I develop in this paper a conception of artefacts based on L. Wittgenstein's idea of family resemblance. My approach peruses the notion of frame, which was invented in cognitive psychology as an operationisable extension of this philosophical idea. Following the metaphor of life-cycle I show how this schematic notion of frame may be filled with the content relevant for artefacts if we consider ...
