Assessment of Prototype Hand-held Fundus Camera

University of Rochester1 enrolled

Overview

This is the proof of concept study to evaluate the performance of an early stage prototype of a hand-held fundus camera.

We tested a novel fundus camera. The images obtained were acceptable to move to the next step in development.

Outcomes

Primary Outcomes

Number of Participants Who Have an Acceptable Image (Image Score of 3 or Higher) of Their Eye With the Hand Held Camera

Will determine if the hand held camera is comparable to the traditional table mount camera in quality of images. The quality of the image of the participant's eye taken with the hand held camera will be compared to the quality of the image taken with the table mount camera using the following scale. We will determine the number of participants who have a score of 3 or higher. Scale Image scored as follows 1. Unacceptable: cannot see fundus detail 2. Unacceptable: fundus detail visualized, but inadequate for meaningful analysis 3. Acceptable: fundus detail visualized to make general comments, modest improvement image would be of sufficient quality for use 4. Good: fundus detail visualized, meaningful analysis possible, std photo superior 5. Excellent: fundus detail visualized as well as std photo 6. Superior: fundus detail of higher quality than std photo
