Reproducibility of non-mydriatic retinographies. Ramirez Mercado, G. Bonnin Arias, Cristina Natalia Navarro Valls, J.J. González Montero, María Guadalupe Martín Pérez, Yolanda Sánchez Ramos, Celia PURPOSE: The purpose is to know the stability of the taken registries basic of eye by means of non-Mydriatic retinography. METHODS: The sample has been of 20 eyes of young people of both sexes between 19 and 35 years old. The measurements were carried out with a non-mydriatic retinal camera model Topcon TRC-NWS in mesopic conditions maintaining the fixation point stable. The number of times in wich each eye was measured was 10- Two condinates in each of the five points determined were located points that are P1_First intersection point between the nasal vein superior and pupilla, P2_ Fist intersection point between the nasal Artery inferior with pupila. P3_First intersection point of the nasal vein inferior with papila (the direction always was according to the needles of the clock); P4_ First bifurcation nasal vein; P5_ superior_First Bifurcation nasal artery superior. For the static analysis was used the stagraphics. CONCLUSION: The reproducibility of the registries of non-mydriatic retinal camera is very elevated for the selected points. These reseults enable us to consider the retina as a key element to implement in new security devices. 2024-10-14T15:21:36Z 2024-10-14T15:21:36Z 2024-10-14T15:21:36Z 2010-10-09 conference poster https://hdl.handle.net/20.500.14352/108953 XXXX-XXXX eng open access
