In 20\u201370% of cases, Zoster Ophthalmicus can lead to ocular involvement, affecting various orbital structures. Orbital myositis is a rare but severe complication of herpes zoster ophthalmicus. We present a case of a 52-year-old man with no significant medical history who developed zoster-associated right ocular myositis and dacryocystitis. He was treated with intravenous acyclovir and oral steroids. A review of the literature identified 29 patients across 19 studies. The median age was 61 years, with a slight female predominance. In 55% of cases, the patients had no notable medical history. The most common presentation of myositis involved all oculomotor muscles. There were 22 cases who were treated with intravenous antiviral therapy and 19 received steroids. A full resolution of symptoms was achieved in 51.7% of patients. Zoster-related orbital myositis is a rare complication that should be considered even in immunocompetent individuals. It may occur either before or after the appearance of a vesicular rash. Magnetic resonance imaging is the preferred radiological exam for assessing orbital involvement. Intravenous antiviral therapy should be started within 72 h of symptom onset, and its combination with systemic corticosteroids appears to be an effective treatment for zoster-related ocular myositis.<\/jats:p>","DOI":"10.3390\/pathogens13100832","type":"journal-article","created":{"date-parts":[[2024,9,26]],"date-time":"2024-09-26T08:20:52Z","timestamp":1727338852000},"page":"832","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Orbital Myositis after Herpes Zoster Ophthalmicus: A Case Report and a Narrative Review of the Literature"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0813-8181","authenticated-orcid":false,"given":"Edoardo","family":"Pace","sequence":"first","affiliation":[{"name":"Department of Medical Sciences, Internal Medicine, University of Turin, 10126 Turin, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guido","family":"Accardo","sequence":"additional","affiliation":[{"name":"Department of Medical Sciences, Infectious Diseases, University of Turin, 10126 Turin, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3865-9519","authenticated-orcid":false,"given":"Tommaso","family":"Lupia","sequence":"additional","affiliation":[{"name":"Unit of Infectious Disease 2U, University Hospital Citt\u00e0 della Salute e della Scienza di Torino, 10100 Turin, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0944-6992","authenticated-orcid":false,"given":"Maria Felice","family":"Brizzi","sequence":"additional","affiliation":[{"name":"Department of Medical Sciences, Internal Medicine, University of Turin, 10126 Turin, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Silvia","family":"Corcione","sequence":"additional","affiliation":[{"name":"Department of Medical Sciences, Infectious Diseases, University of Turin, 10126 Turin, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8338-0130","authenticated-orcid":false,"given":"Francesco Giuseppe","family":"De Rosa","sequence":"additional","affiliation":[{"name":"Department of Medical Sciences, Infectious Diseases, University of Turin, 10126 Turin, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,9,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"197","DOI":"10.1038\/nrmicro3215","article-title":"Molecular Mechanisms of Varicella Zoster Virus Pathogenesis","volume":"12","author":"Zerboni","year":"2014","journal-title":"Nat.
