Telemedicine for screening eye disease in the remote Peruvian Amazon: proof-of-concept

Abstract: Background Improvements in technology could facilitate task-shifting and ocular disease screening in rural areas. Methods Visual acuity (VA) was tested using a Ministry of Health 3-m VA card. Anterior segment photographs were taken using a three-dimensional printed cellphone attachment and remotely graded. Results Of 326 photographed eyes, 1 was ungradable. O… Show more

“…In 16 Amazon villages from Alto Amazonas that did not have access to ophthalmology specialists, Nesemann et al performed a screening for visual-health problems in adults over 50 years of age [37]. The measurement of visual acuity (VA) was performed using a VA measurement card approved by the Ministry of Health of Peru and photographs of the anterior segment of the eye using a smartphone accessory created via 3D printing.…”

“…The results of the VA evaluation and photographs were evaluated by specialists remotely. As a result of the evaluation, 123 people with non-refractive visual impairment were identified, and among the most frequent diseases were pterygium, corneal opacity, and tuberculosis [37]. However, inter-rater agreement between the seven photo-graders had poor reliability for cataract (ICC 0.42) and corneal-opacity (ICC 0.37) diagnosis, moderate reliability for pterygium (ICC 0.67) diagnosis, and good reliability for phthisis-bulbi (ICC 0.76) diagnosis.…”
