Management of intrascleral chestnut burr spines under ultrasound biomicroscopy guidance. Indian Journal of Ophthalmology. 2022 Sep; 70(9): 3311-33151998-36890301-4738http://imsear.searo.who.int/handle/123456789/224571Purpose: To explore the efficacy of ultrasound biomicroscopy (UBM) as a tool for detecting and localizing intrascleral chestnut burr spines. Methods: Individuals who were diagnosed with definitive or suspected intrascleral chestnut burr injuries between 2019 and 2020 were retrospectively reviewed. All patients underwent UBM to detect potential intrascleral spines. UBM imaging features were recorded and analyzed. Intrascleral spines were removed based upon UBM?guided localization. Patient clinical profiles, management, and treatment outcomes were recorded. Results: A total of 10 eyes (10 patients; 6 males, 4 females) were diagnosed with intrascleral spines over the study period, with an average patient age of 55 years (range: 39–71). Three of these 10 eyes exhibited involvement of the palpebrae and cornea, whereas three exhibited corneal involvement, and the remaining four patients exhibited only intrascleral spine injuries owing to their having undergone previous intracorneal spine extraction procedures. UBM features consistent with chestnut burr spines manifest a hyperechoic spot with a shadow. UBM enabled the precise localization of these spines and thus ensured their successful removal via a single surgery. During follow?up, two patients experienced vitreous hemorrhage due to a penetrating injury into the ciliary body that was gradually absorbed. All patients with eye irritation and red eyes progressed favorably, and no surgical complications were recorded. Conclusion: A retained scleral chestnut burr spine should be suspected if a patient complains of persistent eye irritation following intracorneal spine removal. UBM may be a valuable tool for detecting spines retained in the sclera, enabling the successful removal thereof.Intrascleral chestnut burr spinesmanagementUBMJournal ArticleIndiaDepartment of Ophthalmology, Baoan Central Hospital of Shenzhen, Shenzhen, Guangdong, ChinaDepartment of Ophthalmology, Changsha Aier Eye Hospital, Changsha, Hunan, ChinaAier School of Ophthalmology, Central South University, Changsha, Hunan, China
