Abstract
PEREZ PARRA, Zaadia et al. Topical insulin for treating persistent post-severe corneal ulcer epithelial defect. Rev Cubana Oftalmol [online]. 2023, vol.36, n.4 Epub Feb 15, 2024. ISSN 1561-3070.
The treatment of refractory epithelial defect is a challenge and depends upon the development of preclinical or clinical studies aimed at obtaining effective treatments, among which topical insulin emerges. The objective of this article was to describe the healing response of the corneal epithelium under treatment with insulin eye drops. The cases are presented of two patients with a diagnosis of persistent post-corneal ulcer epithelial defect. Topical insulin was prescribed at one drop every six hours, with evolution towards total corneal epithelialization ten days after the treatment started. The mechanism is suggested by which insulin promotes corneal healing, thus restoring corneal nerves and favoring epithelial cell migration. In both cases, the insulin eye drops were able to promote total epithelial healing of the cornea, making it useful in the treatment of persistent epithelial defect.
