Abstract
A portable scanning laser ophthalmoscope with a wide field of view permits a clinician to directly view the interior of the patient's eye without the use of an external monitor or display. The portable scanning laser ophthalmoscope includes a housing that is sufficiently small to be carried and held by a clinician. The housing contains a source of laser light that is scanned by a scanning system for generating a two-dimensional area of illumination. The housing also includes a battery for providing power to the scanning system. An optical system contained in the housing directs illumination from the scanning system to the patient's eye to illuminate the fundus and also intercepts light reflected by the patient's eye to generate a magnified image of the interior of the patient's eye. The optical system also includes an eyepiece lens through which a clinician looks to directly view the magnified image of the interior of the patient's eye.
