Herpes zoster ophthalmicus: frequency and risk factors for developing uncommon ocular manifestations
CONCLUSIONS: The overall frequency of HZO from 2004 to 2021 was 4.2% and has increased annually since 2012. Uncommon ocular manifestations of PCR-verified HZO, mostly comprised of ARN, were more likely to occur in immunosuppressed patients.PMID:37192736 | DOI:10.1016/j.jcjo.2023.04.011

Neuro-Ophthalmological Complications of the COVID-19 Vaccines: A Systematic Review
Conclusion: Since the implementation of the COVID-19 vaccination campaign in the past year, several post-COVID-vaccination neuro-ophthalmological complications have been described. However, considering the number of individuals that have been exposed to the vaccines, the risk seems very low, and the clinical outcome in most cases is favorable. Therefore, on a population level, the benefits of the vaccines far outweigh the risk of neuro-ophthalmological complications.

Reactivation of varicella zoster infection presenting as acute retinal necrosis post COVID 19 vaccination in an Asian Indian male
CONCLUSION AND SIGNIFICANCE: To the best of our knowledge this is the earliest description of a case that has a viral reactivation following COVID-19 vaccination. Elderly people with pre-existing comorbidities, may be at a risk of both primary coronavirus infection and unconceivable risk of aberrant immune reactions leading to a different virus infection or reactivation need to be kept in mind. We present a possible link between SARS-CoV-2 virus vaccination and varicella zoster reactivation in this patient.PMID:34541931 | DOI:10.1177/11206721211046485

Herpes simplex virus, varicella-zoster virus and cytomegalovirus keratitis: Facts for the clinician
Ocul Surf. 2021 Jul 24:S1542-0124(21)00073-2. doi: 10.1016/j.jtos.2021.07.002. Online ahead of print.ABSTRACTKeratitis due to Herpes simplex virus (HSK), Varicella-Zoster virus (VZK) and Cytomegalovirus remains a frequent source of concern for many ophthalmologists. They are a frequent cause of emergency consultations at eye care centers and carry the risk of permanent loss of visual acuity or visual quality and/or chronic neurotrophic keratitis, resulting in a significant decrease in the quality of life. HSK and VZK can affect the corneal epithelium, stroma, or endothelium or a combination of layers. In contrast, most cas...
