Minimally invasive corneal neurotization improves outcomes in neurotrophic keratopathy
Minimally invasive corneal neurotization surgery is a safe and effective treatment for neurotrophic keratopathy (NK), even in rural, socioeconomically disadvantaged populations, according to a study.
A new retrospective study from West Virginia University analyzed outcomes from 13 patients who underwent corneal neurotization. Most patients had advanced NK (Mackie stage 2 or 3), and nearly 40% had a history of diabetes. Despite a high mean social deprivation index score of 70, all patients achieved corneal epithelialization with no recurrence of epithelial defects over an average 18-month follow-up.
Surgeries involved indirect nerve grafting using lid crease incisions and nerves harvested from the supraorbital, supratrochlear, or infraorbital regions, in collaboration between cornea and oculoplastics specialists.
Overall, 8 patients experienced improved corneal sensation, and 9 saw gains in visual acuity. Corneal transplants post-neurotization were required in 4 patients, and 1 underwent adjunctive chemoembolization for corneal neovascularization. Visual acuity improvements were statistically significant at both 1 year and final follow-up.
