Una escala de gravedad de la degeneración macular asociada a la edad (DMAE), basada en fotografías del fondo de ojo, podría ser utilizada para valorar el nivel de riesgo de los pacientes, respecto a la progresión de la enfermedad.
Investigadores del Age-Related Eye Disease Study Research Group (AREDS) han desarrollado un escala de nueve grados de gravedad de DMAE, combinado una de seis grados de drusas y otra de cinco grados de anomalías pigmentosas. Según informa “Archives of Ophthalmology”, en esta nueva escala, el riesgo a cinco años de DMAE avanzada se incrementa progresivamente desde menos de 1% en el grado 1, hasta un 50% en el grado 9.
La escala se ha desarrollado basándose en el análisis de fotografías en color estereoscópicas del fondo del ojo, tomadas al iniciar el estudio y tras un seguimiento de 2 años y después cada año, de los 3.212 participantes del AREDS.
