Adapter for retinal imaging using a hand held computer

Abstract

An adapter configured to engage with a hand held computer device to allow a camera on the hand held computer device to take a high quality image of an eye. The adapter allows for high quality imaging of the anterior portion of the eye and the posterior portion of the eye. The adapter can include additional modular components such as an optical pathway enclosure and a beamsplitter module.

What is claimed is: 
     
         1 . An adapter configured to engage with a hand held computer device with a camera having an optical axis comprising:
 an anterior adapter portion comprising: a body, a clamp configured to engage with the hand held computer device at a first location and a second location, a lens holder engaged with a macro lens movable between a first position in the optical axis of the camera and a second position outside of the optical axis of the camera, an adjustable light source with a light axis parallel to a macro lens optical axis, a third engagement surface configured to slidably engage with the hand held computer device at a third location, and a complementary surface of the body configured to reversibly engage with a base section of a posterior portion, wherein the clamp defines an axis and the body of the anterior adapter portion is configured to move along the axis of the clamp; and   the posterior portion comprising: the base section configured to reversibly engage with the complementary surface of the body of the anterior adapter portion, a telescoping section movable relative to the base section, and a lens holder engaged with a distal end of the telescoping section configured to removably engage with an ophthalmoscopy lens, the base section configured to removably engage with the body of the anterior adapter portion to form an optical axis between the ophthalmoscopy lens and the camera of the hand held computer device.
