Neuro-ophthalmic complications of varicella-zoster virus
Curr Opin Ophthalmol. 2023 Aug 22. doi: 10.1097/ICU.0000000000000996. Online ahead of print.ABSTRACTPURPOSE OF REVIEW: This review broadly describes recent neuro-ophthalmic manifestations of varicella-zoster virus (VZV) reported in literature.RECENT FINDINGS: Despite varicella vaccination, the incidence of herpes zoster continues to rise, potentially leading to devastating consequences when ocular complications occur.A small but growing literature documents cases of retinal disease because of varicella reactivation after SARS-CoV-2 vaccination, ischemic optic neuropathy occurring during herpes zoster ophthalmicus, VZV-indu...

Pole-to-pole involvement of varicella zoster virus reactivation following COVID-19 vaccination
We present a possible link between anti-SARS-CoV-2 virus vaccination and varicella zoster reactivation in these patients and also describe the clinical features, imaging findings including confocal imaging, corneal nerve fiber analysis, and management with detailed discussion.PMID:37203073 | DOI:10.4103/IJO.IJO_2942_22

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

Fight Aging! Newsletter, February 13th 2023
This study investigated whether taller Polish adults live longer than their shorter counterparts. Data on declared height were available from 848,860 individuals who died in the years 2004-2008 in Poland. To allow for the cohort effect, the Z-values were generated. Separately for both sexes, Pearson's r coefficients of correlation were calculated. Subsequently, one way ANOVA was performed. The correlation between adult height and longevity was negative and statistically significant in both men and women. After eliminating the effects of secular trends in height, the correlation was very weak (r = -0.0044 in men and ...

COVID-19 Vaccine-Associated Ocular Adverse Effects: An Overview
CONCLUSIONS: Evidence regarding the ocular adverse effects does not outweigh the benefits of SARS-CoV-2 vaccination in patients with pre-existing systemic or ophthalmic diseases. This review provides insights into the possible temporal association between reported ocular adverse events and SARS-CoV-2 vaccines; however, further investigations are required to identify the link between potential causality and pathological mechanisms.PMID:36366386 | DOI:10.3390/vaccines10111879

Herpes Zoster Ophthalmicus: A Devastating Disease Coming Back with Vengeance or Finding Its Nemesis?
J Ophthalmic Vis Res. 2022 Jan 21;17(1):123-129. doi: 10.18502/jovr.v17i1.10177. eCollection 2022 Jan-Mar.ABSTRACTHerpes zoster ophthalmicus is a frequent, painful, and debilitating condition caused by the reactivation of the varicella-zoster virus alongside the ophthalmic branch of the trigeminal nerve. Twenty-five percent of adults will develop the disease during their lifetime with the risk increasing to one in two over the age of 50. Herpes zoster ophthalmicus presents with a plethora of ocular manifestations ranging from the characteristic rash in the distribution of the ophthalmic branch of the fifth cranial nerve to...
