Hair removal is recommended to avoid possible intraocular migration, still residing hairs did not cause any serious long-term complications in our cohort.</p><p><strong>Key messages: </strong>What is known Within the late spring and early summer season, mass reproduction of the oak processionary carterpillar (OPC) can lead to an increased number of patients with OPC-related eye complaints (pain, itching and burning sensation) caused by OPC hairs within a very short period of time. Within that season, people should be (more) actively sensitized to avoid trees with OPC hairs, take precautions and avoid eye rubing when having complaints What is new Complete surgical removal of the hairs can be difficult and is often unsuccessful due to their tiny size and often stromal location most possibly resulting from eye rubbing In the longer-term, residing hairs have shown to develop haze adjacent to the hair, migrate within the cornea or disappear/resolve. Since this may go along with an inflammatory reaction, long-term follow-up and topical steroids may be useful.</p>","PeriodicalId":12795,"journal":{"name":"Graefe’s Archive for Clinical and Experimental Ophthalmology","volume":" ","pages":"771-779"},"PeriodicalIF":2.4,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11953161/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142618756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
