“…Among them, optic nerve head cupping, suspicious for glaucoma, was the most common in both rural (10.5%) and urban sites (7.6%). The usefulness of nFP for diagnosing diseases other than diabetic retinopathy, such as glaucoma suspects, 30 retinopathy of prematurity, age-related macular degeneration, or other vitreoretinal diseases, is being investigated.…”

Purpose: To evaluate the relative diagnostic value of nonmydriatic fundus photography (nFP) among patients screened for diabetic retinopathy in remote rural medical clinics and an urban academic medical center for nonadherence to recommended annual dilated eye examination. Subjects and Methods: A retrospective cross-sectional study was performed among diabetic patients seen in primary outpatient clinics between 2006 and 2011 who were screened for diabetic retinopathy with nFP for history of nonadherence to recommended annual dilated eye examination. A single nonstereoscopic, 45°, 10-megapixel digital image of the disc and macula of both eyes was obtained locally and transmitted electronically to a retinal specialist for remote review. The results from remote rural Native American Indian reservations were compared with those from an urban academic family practice clinic. The proportion of subjects diagnosed with diabetic retinopathy and the quality of fundus images were compared. Results: Among 872 patients (1,744 eyes) screened from rural sites and 517 subjects (1,034 eyes) screened from an urban site, images were of good quality for evaluation in 82.4% and 85.7% of subjects, respectively. Diabetic retinopathy was noted in 12.6% of rural subjects and 29.6% of urban subjects (p < 0.001). Conclusions: nFP can be a useful tool in both rural and urban settings to screen for diabetic retinopathy in patients who are nonadherent to the recommended dilated annual eye exam. In our study population, a surprisingly higher percentage of diabetic subjects screened from the urban clinic had retinopathy compared with subjects screened in rural clinics.

“…Non-mydriatic fundus cameras have been shown to be satisfactory for screening optic disc cupping [54,55]. Combined with the use of telemedicine, digital fundus cameras have enormous potential for community glaucoma screening in remote or non-hospital environments.…”

“…Se han utilizado instrumentos de imagen para la detección de glaucoma por telemedicina (7,8) pero no se han encontrado en la literatura referencias acerca de la aplicación de la oftalmoscopía con láser confocal y la perimetría de duplicación de frecuencia. La sensibilidad y especificidad obtenidas tras la evaluación subjetiva, por uno o varios oftalmólogos, de fotografías de la papila se cifra en 70% y 97% respectivamente (6).…”

RESUMENPropósito: Evaluar las dificultades y el grado de aceptación y satisfacción entre la población participante durante una campaña de detección de glaucoma por telemedicina. Este trabajo es parte de un estudio global de desarrollo, aplicación y evaluación del SisGlaTel financiado por el Fondo de Investigaciones Sanitarias (FIS) y Pfizer Ophthalmics. Método: Se desarrolló un sistema de telemedicina sobre un programa específico en JAVA™. Se instaló la estación remota en el Centro de Atención Primaria. Los sujetos participantes firmaron un consentimiento informado, y fueron sometidos a varias pruebas diagnósticas (perimetría de duplicación de frecuencia-FDT, oftalmoscopia con láser confocal-HRT y tonometría). Se analizaron los resultados de las pruebas y los problemas observados en la aplicación del sistema. Se realizó una encuesta a 99 personas que acababan de participar voluntariamente en el programa de detección de glaucoma entre población de riesgo. La encuesta incluyó 7 pregun-ARTÍCULO ORIGINAL ABSTRACT Purpose: To evaluate the problems, and the degree of acceptability and satisfaction among participants in a telemedicine screening program. This study forms part of a global project for the design, implementation and evaluation of SisGlaTel funded by the Fondo de Investigaciones Sanitarias (Spain) and Pfizer Ophthalmics. Method: A telemedicine system was built based on a specific program written in JAVA™. The remote station was located at a Primary Care Center. Participants signed an informed consent, and completed a questionnaire and undertook different tests (frequency doubling perimetry-FDT, confocal scanning laser tomografy-HRT and tonometry). Test results and problems detected were analysed. Ninety-nine subjects completed a satisfaction questionnaire after voluntarily participating in the screening program among an at-risk population. The questionnaire included 7 questions, four of which required participants to categorise their responses, ranging from very bad (1) to excellent (5), to questions
