Intraoral and intranasal photography using a retinal fundus camera

Like other subspecialities in biomedical imaging, clinical ophthalmic photography requires specialized instrumentation to produce informative photographs. Photographic slit-lamps, external ocular cameras, and retinal fundus cameras each have optical and illumination components that are designed to yield optimal results within narrow subject contexts. A variety of ophthalmic pathologies are associated with lesions in other parts of the body. One disease, cicatricial pemphigoid, causes changes in the mucosal tissue of the nasal and oral passages in addition to conjunctival findings. Lacking endoscopic instrumentation, we capitalized on the design parameters of a retinal fundus camera to produce photographs of these remote lesions.
