Corneal confocal microscopy (CCM) may be useful as a diagnostic tool in painful diabetic neuropathy (PDN), and showed that greater corneal nerve loss was associated with increased pain severity.
Why this matters
Approximately one in five adults with diabetes have PDN. It has significant impact on quality of life, and current treatments show limited efficacy.
Accurate diagnosis of PDN will aid in the identification of patients for clinical trials and the subsequent development of more effective treatments.
