Photobleaching device and method and dark adapted perimetry device and dark adapted perimetry method

摘要

A dark adapted perimetry device comprising a photobleaching device, a concave, array guide, the guide comprising a stimulus target array comprising a plurality of stimulus target light sources positioned within the guide and a control unit to selectively illuminate light sources comprised in the plurality of stimulus target light sources at a predetermined luminance is disclosed. The stimulus target light sources may be illuminated by a LED complex source comprising two or more LEDs. Also disclosed is a method using the perimetry device. A bleaching device comprising an eye piece for positioning the eye, a locator for moving the bleaching device into and out of the optical path, an imaging system for tracking the gaze direction or a fixation target, an illumination source and a bleach control device to control the brightness and pulse form of the illumination source is also disclosed along with a method of photobleaching.
