Topical treatment with a new matrix therapy agent (RGTA) for the treatment of corneal neurotrophic ulcers.

Purpose: Neurotrophic keratopathy is a degenerative disease of the corneal epithelium resulting from impaired corneal innervation, possibly leading to perforation. We aimed to assess the efficacy and tolerance of a new matrix therapy agent (RGTA, Cacicol20), mimicking heparan sulfates, for the management of neurotrophic keratopathy.

Methods: We carried out an uncontrolled, prospective, single-center clinical study on 11 patients (11 eyes) with severe corneal neurotrophic ulcers, despite the use of preservative-free artificial tears, for 15 days.
