In humans, eccrine sweat glands play important roles in regulating body temperature.[1],[2] Secretory coils and ducts are two components of eccrine sweat glands and have different structures and functions.[1] Eccrine sweat glands are innervated mainly by terminal nerve fibers, which are expressed at low levels.[1],[3] Therefore, it is difficult to detect these peripheral nerve fibers by standard histochemical techniques, and signal amplification is required.[1],[4] The tyramide signal amplification (TSA) system is a technique used to amplify weak signals and can be easily integrated into standard immunofluorescence (IF) protocols.[3],[5],[6],[7],[8] In this study, we combine standard IF with TSA to characterize weakly expressed nerve fiber antigens.

In the subjects with improved glycemic control, corneal nerve fiber density and corneal nerve fiber length increased significantly compared to baseline, whilst those with poor HbA1c showed a significant reduction in sural sensory nerve conduction velocity, corneal nerve fiber density, and corneal nerve fiber length.
Glaucoma is an optic neuropathy characterized by excavation of the optic disc, thinning of the peripapillary retinal nerve fiber layer (pRNFL), and a specific pattern of visual field loss.
Additional analyses within the same cohort have shown that, in patients with PD, the amount of [alpha]-synuclein positive nerve fibers normalized to total intraepidermal nerve fiber density ([alpha]-synuclein ratio) is enhanced in both sympathetic cholinergic (sweat gland innervating) and sympathetic adrenergic (pilomotor muscle innervating) nerve fibers.
Recent studies, implementing contemporary imaging modalities such as scanning laser polarimetry (SLP) and/or optical coherence tomography (OCT), reported that transient IOP spikes during LASIK have no impact on peripapillary retinal nerve fiber layer (RNFL) thickness [4, 5].
Objective: To compare mean retinal nerve fiber layer (RNFL) thickness in patients having pseudo exfoliation (PXF) with normal age matched controls using spectral domain optical coherence tomography (SD-OCT).
Objectives: The presence of retinal nerve fiber layer (RNFL) split bundles was recently described in normal eyes scanned using scanning laser polarimetry and by histologic studies.
