System and method for a portable eye examination camera

Abstract

A system and method for a portable eye examination camera is described herein. The system and method may include: a light source disposed within said portable camera at a set distance away from an eye of a patient; a first lens within said portable camera for focusing the light from said light source onto a retina of the eye and providing a wide field retinal image; a second lens for receiving said retinal image and causing a magnification of said retinal image; and a digital camera within a mobile computing device for recording said retinal image.

         22 . A method of providing a retinal image of a patient comprising:
 illuminating a retina of the patient with an LED light source within a portable camera, wherein the portable camera has a first lens and a second lens, and wherein the first lens is capable of focusing light from the LED light source onto the retina of the patient and providing a wide field retinal image, and wherein the second lens is capable of receiving the retinal image and causing a magnification of the retinal image;   
       illuminating the retina of the eye with the LED light source at a set distance away from the eye; and
 recording the retinal image. 
 
     
     
         23 . The method of  claim 22 , wherein the first lens has a power greater than said second lens. 
     
     
         24 . The method of  claim 22 , wherein the LED light source is substantially coaxial with that of receiving optics. 
     
     
         25 . The method of  claim 22 , wherein said first lens is a biconvex aspherical lens. 
     
     
         26 . The method of  claim 22 , wherein said second lens is a biconvex achromatic lens. 
     
     
         27 . The method of  claim 22 , wherein a focal length of said second lens is greater than that a focal length of said first lens. 
     
     
         28 . The method of  claim 22 , wherein the distance between said first and second lens is a sum of the focal lengths of said first and second lens. 
     
     
         29 . The method of  claim 22 , wherein the portable camera further comprises two polarizing filters: a first filter placed in front of the LED light source and a second filter placed in front of second lens, wherein the second filter is placed at 90 degree polarity in respect to the first filter. 
     
     
         30 . The method of  claim 22 , wherein the method is performed without dilating a pupil of the eye.
