Emerging Strategies in Treating Corneal Alkali Burns: A Narrative Review

Abstract

Corneal alkali burns represent a complex and debilitating ocular injury, necessitating innovative strategies for effective management. This narrative medical review seeks to provide a comprehensive exploration of emerging approaches in the treatment of corneal alkali burns. The primary objectives of this review are multifaceted. First, we aim to unravel the intricate pathophysiology of corneal alkali burns, delving into the immediate and long-term consequences of alkali exposure on ocular tissues. Understanding the underlying mechanisms, including oxidative stress, inflammation, and neovascularization, is essential for the development of targeted therapeutic interventions. Second, we assess the efficacy of novel treatment modalities, encompassing pharmacological agents and surgical techniques, with a focus on their ability to mitigate corneal damage, facilitate tissue regeneration, and preserve visual function. By analyzing the latest clinical findings, we aim to identify promising avenues for improved patient outcomes. Temporal dynamics play a crucial role in the healing process, and thus our review investigates the progression of corneal lymphangiogenesis and the expression patterns of key growth factors, such as vascular endothelial growth factor-C (VEGF-C). These insights into the timing of corneal healing provide valuable guidance for tailoring therapeutic interventions to specific stages of injury. Finally, we delve into regenerative therapies, particularly the potential of mesenchymal stem cells (MSCs) and their secretome as anti-inflammatory and antiangiogenic agents. By summarizing the promising results from preclinical and clinical studies, we illuminate the prospects of regenerative approaches in corneal alkali burn management. This narrative review aspires to serve as an indispensable resource for clinicians, researchers, and healthcare professionals involved in the treatment of corneal alkali burns. By addressing these objectives, we aim to foster a deeper understanding of this challenging condition, facilitate the development of innovative strategies, and ultimately enhance patient outcomes in the realm of corneal health and vision preservation.
