Amniotic Membrane Transplantation in Refractory Neurotrophic Corneal Ulcers

Purpose: This study was designed to compare and evaluate the efficacy of amniotic membrane transplantation with the conventional management (tarsorrhaphy and bandage contact lens) in eyes with refractory neurotrophic corneal ulcers. Methods: Thirty eyes of 30 patients (14 females and 16 males) with neurotrophic corneal ulcers refractory to medical management were included and divided randomly into group 1 (n = 15), who received conventional management with a tarsorrhaphy (n = 11) or bandage contact lens (n = 4), and group 2 (n = 15), who underwent Amniotic Membrane Transplantation. The outcome parameters evaluated were epithelialization time, duration of healing of corneal ulcers, and improvement in best corrected visual acuity. Results: The mean age in our study was 37 ± 14.71 years. At the end of 3 months follow-up, 10 of 15 patients (66.67%) in group 1 showed complete epithelialization and subsequent healing and 11 of 15 patients (73.33%) in group 2 showed complete epithelialization and healing (P > 0.05). The median time for complete epithelialization was 21 days in both groups. Both groups showed an improvement in the best-corrected visual acuity. Conclusions: Both amniotic membrane transplantation and conventional management (tarsorrhaphy or bandage contact lens) are effective treatment modalities for refractory neurotrophic corneal ulcers.
