To evaluate the ease of use, feasibility, and quality of fundus photograph images using the new 'Pictor' (Volk Optical Inc. Mentor, OH) camera.
The Pictor camera is a portable, hand-held camera that takes digital, still and video images, mydriatic and non-mydriatic fundus photographs in addition to anterior segment imaging. The images have a 45-degree field of view with a resolution of 1920 x 1440 pixels and are captured as .jpeg files. Images can be downloaded to a computer via a USB device.For this study, the Pictor camera was set up with the retinal module attachment. The following imaging settings were used: still capture mode, medium illumination brightness, high IR illumination. Focus settings were set to normal shoot and auto-focus mode - the auto-focus ranging from +8 to -20D. The device settings and all other settings were factory installed unless otherwise specified. Infra-red targeting/white light was used to capture the image with optimal illumination level. Fundus photographs were obtained with the Pictor camera on fifty patients, who had been dilated for various reasons on the day of examination. A single operator took all fundus photographs on all patients under dim illumination conditions. All images were downloaded to the computer and analyzed for it's quality.
Although there was an initial learning curve, the quality of the pictures were generally good. It was easier to obtain pictures in patients with dilated pupils than undilated pupils.
The camera image quality was good. The Pictor camera may have a possible role in bedside exam documentation, telemedicine, and photo documentation of retinopathy of prematurity.
