Original publication title: Anterior and posterior segment photography. An alternative approach using a dSLR camera adaptor.
Plain-English summary
Researchers have developed a new camera adaptor that allows veterinarians to take clear, high-quality pictures of the front and back parts of the eye in dogs, cats, and horses. This adaptor works with a specific type of camera and lens setup, and it helps eliminate unwanted reflections that can make images unclear. The device is easy to carry and set up, making it convenient for use in veterinary practices. Overall, this new adaptor offers a cost-effective way to capture detailed images of animal eyes compared to traditional imaging systems.
Abstract
PURPOSE:   To describe a novel digital single lens reflex (dSLR) camera adaptor for anterior and posterior segment photography. METHODS:   The adaptor was used to evaluate canine, feline, and equine patients presenting to Tufts Ophthalmology service. Anterior segment imaging was conducted with the adaptor mounted between a dSLR camera body (Canon 7D) and a macro lens (Canon EF-S 60mm/f2.8). Posterior segment imaging was performed with the aid of an indirect ophthalmic lens mounted in front of the macro lens. Coaxial illumination during viewing was provided by a single white light-emitting diode (LED) within the adaptor, while illumination during exposure was provided by the pop-up flash or an accessory flash. Corneal and/or lens reflections were eliminated using a pair of linear polarizers, having their azimuths at right angles to one another. RESULTS:   This dSLR camera adaptor provides quality high-resolution, reflection-free, images of both the anterior and posterior segments. It was easy to transport, assemble, and handle. The necessary adjustments, positioning, and focusing required for quality images were easily performed. CONCLUSION:   The described dSLR camera adaptor provides an alternative to existing imaging systems. High-resolution image acquisition occurred at a fraction of the cost of established imaging system, particularly those devoted to the posterior segment.
