De Clerck EEB, Schouten JSAG, Berendschot TTJM, et al. - Using multivariable linear regression, researchers desired to know to what extent a decrease in corneal nerve fibre length (CNFL) is present in people with prediabetes or type 2 diabetes (DM2) vs people with normal glucose metabolism (NGM). For this analysis, they evaluated total CNFL per mm² in the subbasal nerve plexus of the cornea in 134 candidates (mean age 59 ± 8 years, 49% men, 87 NGM, 20 prediabetes, 27 DM2) utilizing composite images acquired by corneal confocal microscopy. In people with DM2 vs people with NGM, a significant reduction in CNFL was observed. A pattern of reduction in CNFL between people with NGM and prediabetes has been reported. Reducing the length of corneal nerve fibre may lead to a delayed healing of the cornea and an increased risk of corneal complications following surgery.
