IVCM images showed focal areas of abnormally increased tortuosity (Fig. 1A, B, C and D), whereas adjacent regions showed nerves that were long, straight and much fewer in number. In some regions, only one linear nerve fiber was present.
Optical coherence tomography showing thinning of the retinal nerve fiber layer. Focal asymmetries were noted between OD and OS.
