Abstract
In the past, clinical trials in neuro-ophthalmology have focused upon functional endpoints including Snellen visual acuity and visual field testing, both of which may have significant test/retest variability because of their dependence upon subject alertness and cognitive function. The introduction of optical coherence tomography (OCT) into the practice of clinical ophthalmology has now extended into clinical trials in both ophthalmology and neurology. Recent advances in the resolution and reproducibility of spectral-domain OCT have now produced algorithms that measure the structural integrity of the optic nerve and retina. OCT is in vivo histopathology and the qualitative and quantitative metrics of this painless, noninvasive, non-contact technology can now be correlated with traditional functional measurements to provide a complete longitudinal profile of the afferent visual system for clinical trials.
