Cataract prescreening systems and methods

摘要

Methods and systems for prescreening a patient of ocular disease are disclosed. One method of corneal analysis includes steps of providing blue light from a light source into the corneal area of a patients eye and assessing the illuminated corneal area of a patients eye to detect the presence of cataract material. Another method of corneal analysis, includes steps of providing blue light from a light source into the corneal area of a patients eye, recording illumination of the corneal area and assessing recorded illumination of the corneal area to detecting the presence of cataract material. An apparatus is described for analyzing the corneal area of a patients eye including an illumination source for providing blue light into the corneal area of a patients eye. An apparatus is also described for assisting an evaluation of disease in a patient's eye that includes blue light illumination source for illuminating the corneal area of the eye, imaging means for recording illumination of a the eye and an imaging area for providing a controlled environment for illumination and imaging of the corneal area of the eye. Also described is the combination of an apparatus for prescreening for cataracts with a glaucoma assessment apparatus.
