An update on viral conjunctivitis treatment strategies: a narrative literature review

Viral conjunctivitis is a highly contagious ocular condition that significantly impacts patient quality of life and healthcare resources. Despite its self-limiting nature, the condition remains a significant public health concern due to its high transmissibility, prolonged symptoms, and potential complications such as subepithelial infiltrates (SEIs). This review aimed to synthesize and evaluate current management strategies for adenoviral conjunctivitis and provide an evidence-based treatment framework. A systematic literature search of PubMed and the Cochrane Library was conducted, identifying 25 eligible studies published between 2009 and 2024 that focused on clinical interventions including supportive care, antiseptics, corticosteroids, antivirals, and immune modulators. The findings indicate that while supportive therapy and hygiene measures remain central to care, antiseptic agents, specifically povidone–iodine, and topical steroids offer additional benefit in reducing symptom duration and complications. Combination therapies integrating antiseptics, corticosteroids, and immunomodulators show promise for more severe cases, especially those complicated by SEIs. This review proposes an evidence-based comprehensive, multimodal approach management algorithm while highlighting the need for future research in antiviral development and diagnostic innovation to avoid mistreatment and unnecessary antibiotic use.
