Portable fundus viewing system for an undilated eye

A portable system for viewing the fundus of an undilated eye comprising:

• a plurality of point sources of light individually actuable and arranged in a line;
• a lens for converting a point of light from said sources to a line of light;
• an optical system for directing light from said lens to an undilated eye;
• a controller for sequentially actuating said point sources of light to scan the fundus of the eye with lines of light directed to the eye by said optical system;
• an image detector for receiving light reflected from the fundus and directed to the detector by said optical system, said detector generating signals representing the image of the fundus;
• and
• a display responsive to said signals for displaying an image of the fundus.

A system for viewing the fundus of an undilated eye comprising:

• a linear array of a plurality of light emitting diodes;
• a cylindrical lens for receiving light from said array through a slit aperture to generate a line of light;
• an optical system for directing light from said lens to an undilated eye;
• a controller for sequentially actuating said light emitting diodes to scan the fundus of the eye with lines of light directed to the eye by said optical system;
• and
• image generating apparatus for receiving light reflected from the fundus and directed to the image generating apparatus by said optical system to provide an image of the fundus.

A system for viewing the fundus of an undilated eye comprising:

• a hand held unit for scanning light into an undilated eye to illuminate the fundus of the eye and responsive to light reflected from the eye to generate signals representing an image of the fundus;
• a display responsive to signals representing said fundus image signals generated by said hand held unit for displaying an image of the fundus;
• and
• a printer responsive to signals representing said fundus image signals generated by said hand held unit for displaying an image of the fundus.
