What We Can Do in Infectious Keratitis, Except for Conventional Antimicrobial-Based Therapies: Major Narrative Review
Abstract
Background and aims: Infectious keratitis (IK) is classified as a critical ophthalmic emergency, with the potential to result in vision-impairing complications. The treatment approach involves the use of pharmacological antimicrobial agents in combination with surgical interventions. Traditionally, the management of IK has relied on conventional antimicrobial agents, although the specific treatment regimen may vary based on the underlying causative agent. The growing antimicrobial resistance, along with the less favorable outcomes in most cases, emphasizes the urgent need for adjunctive or novel therapies. This report aims to provide a thorough overview of the current clinical and experimental non-antimicrobial therapies, encompassing both medical and surgical options, whether they serve as adjuncts to antimicrobial treatments or function as independent therapies for IK.
Methods: A comprehensive search on PubMed was undertaken to identify relevant articles. Articles that described conventional antimicrobial-based treatments were excluded from the review. Additionally, case reports and non-English publications were not considered.
Results: Various therapeutic options, including medical-based therapies (povidone-iodine, matrix metalloproteinases inhibitors, corticosteroids, host defense peptides, novel small molecules, formaldehyde releasers, synthetic polymers, antioxidants, and bacteriophages), laser/light-based therapies (photodynamic therapy, ultraviolet C light, thermal…
