Higher magnification lenses versus conventional lenses for evaluation of diabetic neuropathy by corneal in vivo confocal microscopy

Abstract

We tested agreement for small fibre morphology using corneal in vivo confocal microscopy between the recently available higher-magnification 300 μm(2) and the conventional 400 μm(2) field-of-view lenses. We found insignificant bias for corneal nerve fibre length indicating that either lens could reasonably be applied to research and clinical screening for diabetic neuropathy.
