Despite initial focus on respiratory symptoms, the virus revealed significant ocular implications, prompting a reevaluation of the eye's role in its transmission, diagnosis, and systemic effects. The paradoxical nature of SARS-CoV-2-simultaneously novel and familiar within the coronavirus family-has been central to guiding the global medical response, including the swift development of vaccines. The pandemic has intensified research into the eye's susceptibility to viral infections, enhancing our understanding of virus-host interactions and the systemic impacts of viral diseases. The editorial delves into the pathophysiology of SARS-CoV-2, highlighting its potential to trigger autoinflammatory and autoimmune reactions with significant ocular repercussions. It examines the rapid vaccine development and deployment, the associated ocular side effects, and the ongoing research necessary to mitigate these outcomes. As the World Health Organization declared the end of COVID-19 as a public health emergency, the focus has shifted toward understanding the virus's long-term implications, including its effects on ocular health. This work underscores the critical role of interdisciplinary collaboration in addressing the systemic impacts of viral infections. It emphasizes the importance of ophthalmology in the broader context of public health and highlights the need for continued vigilance, research, and adaptation in a postpandemic world.

These components play important roles in corneal cell migration, proliferation, and wound healing. Blood-derived eye drops have demonstrated clinical effectiveness across a spectrum of ocular surface conditions, encompassing dry eye disease, Sjögren's syndrome, graft-versus-host disease, and neuropathic corneal pain (NCP). Currently, management of NCP remains challenging. The emergence of blood-derived eye drops represents a promising therapeutic approach. In this review, we discuss the benefits and limitations of different blood-derived eye drops, their mechanisms of action, and treatment efficacy in patients with NCP. Several studies have demonstrated the clinical efficacy of autologous serum eye drops in relieving pain and pain-like symptoms, such as allodynia and photoallodynia. Corneal nerve parameters were also significantly improved, as evidenced by increased nerve fiber density, length, nerve reflectivity, and tortuosity, as well as a decreased occurrence of beading and neuromas after the treatment. The extent of nerve regeneration correlated with improvement in patient-reported photoallodynia. Cord plasma eye drops also show potential for symptom alleviation and corneal nerve regeneration. Future directions for clinical practice and research involve standardizing preparation protocols, establishing treatment guidelines, elucidating underlying mechanisms, conducting long-term clinical trials, and implementing cost-effective measures such as scaling up manufacturing. With ongoing advancements, blood-derived eye drops hold promise as a valuable therapeutic option for patients suffering from NCP.</p>","PeriodicalId":16689,"journal":{"name":"Journal of Ocular Pharmacology and Therapeutics","volume":" ","pages":"281-292"},"PeriodicalIF":1.9,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11296151/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140858624","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
