Abstract: A dark adapted perimetry method includes the steps of at least partially photobleaching an eye, selectively illuminating a plurality of stimulus target light sources at a predetermined luminance, and recording a response data including triggering an input device in response to the selective illumination. The plurality of stimulus target light sources define a stimulus target array positioned within a concave array guide. Each stimulus target light source is illuminated by a respective LED complex light source.

Abstract: An ophthalmological topographer is disclosed. The ophthalmological topographer includes a corneal topographer and a scleral measurement device including one or more scleral projection systems. Methods of determining topography are also disclosed.

Abstract: 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.
