Abstract: : Purpose: To determine the presence of retinal abnormalities in subjects voluntarily undergoing non–mydriatic imaging in a convention exhibit hall setting. Methods: During several exhibitions in which the Panoramic 200 non–mydriatic camera imaging device was displayed, 269 subjects had their eyes imaged on a complimentary basis. After informed consent and prior to imaging, subjects indicated whether or not they had any known pre–existing eye diseases or abnormalities. The images (called OptomapsTM) were obtained without mydriasis under ambient exhibit hall lighting. These were reviewed by an ophthalmologist for the presence of any retinal abnormalities whatsoever, using the reviewing software which is intrinsic to the unit. Results: A total of 512 eyes of 269 subjects were imaged. Surprising, the majority of eyes had some abnormality with only 26.0% of eyes considered to be completely within normal limits. Drusen were found in 19.1% of eyes and macular drusen were found in 11.3%. Suspicious optic nerves with apparent thinning of the neural rim was found in 9.2%. Retinal hemorrhages were found in 1.6% of eyes, and in 0.4% of eyes, retinal emboli were found along a branch of the central retinal artery. Choroidal nevi were found in 6.9% of eyes and peripheral pigmentary changes were found in 16.1%. Lattice degeneration was identified in 1.8% of the Optomaps and peripapillary pigment atrophy was detected in 43.8% of eyes. Conclusions: A high prevalence of retinal abnormalities was found in subjects with no known eye diseases. Some of the abnormalities were potentially serious. The Panoramic 200 facilitates an effective means of screening for retinal abnormalities in subjects who might otherwise be reluctant or disinclined to present for dilated funduscopic examination.
