Tear biomarkers and corneal sensitivity as an indicator of neuropathy in type 2 diabetes.

Aims: Explore potential of 31 tear biomarkers involved in screening for diabetic peripheral neuropathy (DPN). Assess the utility of aesthesiometry for measuring corneal damage in DPN and determine optimal cutoff point for detecting DPN.

Methods: Screening test pilot study recruited 90 participants from a tertiary hospital in Lima, Peru.
