Greater corneal nerve loss at the inferior whorl is related to the presence of diabetic neuropathy and painful diabetic neuropathy

Painful Diabetic Neuropathy Is Associated With Greater Autonomic Dysfunction Than Painless Diabetic Neuropathy

OBJECTIVE Although a clear link between diabetic peripheral neuropathy (DPN) and autonomic neuropathy is recognized, the relationship of autonomic neuropathy with subtypes of DPN is less clear. This study aimed to investigate the relationship of autonomic neuropathy with painless and painful DPN. RESEARCH DESIGN AND METHODS Eighty subjects (20 healthy volunteers, 20 with no DPN, 20 with painf...

The Inferior Whorl For Detecting Diabetic Peripheral Neuropathy Using Corneal Confocal Microscopy.

PURPOSE In vivo corneal confocal microscopy (CCM) is increasingly used as a surrogate endpoint in studies of diabetic polyneuropathy (DPN). However, it is not clear whether imaging the central cornea provides optimal diagnostic utility for DPN. Therefore, we compared nerve morphology in the central cornea and the inferior whorl, a more distal and densely innervated area located inferior and nas...

Painful Diabetic Neuropathy

N europathic pain exerts a substantial impact on quality of life, particularly by causing considerable interference in sleep, daily activities, and enjoyment of life. Chronic neuropathic pain is present in 13–26% of diabetic patients (1– 4). In a recent survey from Augsburg, Germany, the prevalence of painful polyneuropathy was found to be 13.3% in diabetic subjects, 8.7% in individuals with im...

Painful diabetic neuropathy.

PDN is commonly caused by involvement of either the C fibres or the Aδ fibres. PDN caused by the involvement of small nerve fibers (C fibres), may present without objective clinical findings, such as decreased peripheral reflexes or abnormalities, on routine electrophysiological studies. Small fiber neuropathies may manifest as a number of different clinical symptoms, including allodynia, burni...
