Using platelet-rich plasma to treat neurotrophic keratopathy

Official title: Autologous Platelet-rich Plasma (APRP) in the Treatment of Neurotrophic Keratopathy

Run by Universidad Autonoma de Nuevo Leon · NCT04604834 · Data updated 2026-11-12

This study is testing whether using a special treatment made from your own blood can help people with neurotrophic keratopathy heal their corneas better than just using artificial tears alone.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include patients diagnosed with neurotrophic keratopathy who have corneal erosions and meet specific inclusion criteria related to their medical history.

Probably not a fit

Patients with other ocular surface pathologies that cause corneal erosions but do not involve corneal hyposensitivity may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study investigates the effectiveness of autologous platelet-rich plasma (APRP) in treating neurotrophic keratopathy, a condition that impairs corneal sensitivity and healing. Participants will be randomly assigned to receive either APRP combined with preservative-free artificial tears (PFAT), APRP alone, or PFAT alone in a crossover design over a total of 12 weeks. The goal is to determine which treatment combination leads to better healing outcomes for the cornea. A thorough ophthalmologic evaluation will be conducted before and during the treatment periods to monitor progress and any adverse effects.

Why it matters

Potential benefit: If successful, this treatment could significantly improve healing and comfort for patients suffering from neurotrophic keratopathy.

How similar studies have gone: While the use of platelet-rich plasma in ocular conditions is gaining interest, this specific approach for neurotrophic keratopathy is relatively novel and has not been extensively tested in prior studies.
