Optic nerve: Comparison of technologies

Abstract

Each optic nerve imaging technology has its unique strengths and weaknesses.Each technology is in evolution to minimize it's limitations. Frequency of imaging will be dictated by variables of the individual patient, such as stage of glaucoma or suspicion of progression. Optic disc evaluation is of utmost importance in early glaucoma diagnosis and in monitoring progressive nerve damage. Optic disc and retinal nerve fiber layer (RNFL) abnormalities will often precede corresponding functional loss in glaucoma [1-3]. Therefore, it is imperative to have an objective, quantitative, and reproducible imaging technique capable of making an early diagnosis and monitoring the disease. © 2010 Springer-Verlag Berlin Heidelberg.
