She was also experiencing reces-sion of a treatment-naive lateral rectus muscle and advancementof a recessed medial rectus muscle, with a 1 tendon–width down-ward transposition of the left eye. Swept-source optical coher-ence tomography angiography (OCTA; PLEX Elite 9000 [CarlZeiss Meditec]) with a 10-diopter optical adaptor lens was per-formed on the recessed lateral rectus muscle. The OCTA imagessuggested that conjunctival and episcleral blood flow decreasedimmediately after surgery (Figure, A) but was restored within 2weeks (Figure, B).Spectral-domain OCTA can facilitate the visualization of super-ficial blood flow, as in cases of conjunctival racemose hemangioma.1In this case, swept-source OCTA clearly depicted episcleral blood flowdespite a chemotic conjunctiva. Blood interruption at the anteriorsegment from the anterior ciliary artery after strabismus surgery maybe restored within 2 weeks.ARTICLE INFORMATIONAuthor Affiliations: Department of Ophthalmologyand Visual Sciences, Kyoto University GraduateSchool of Medicine, Kyoto, Japan.Corresponding Author: Manabu Miyata, MD, PhD,Department of Ophthalmology and Visual Sciences,Kyoto University Graduate School of Medicine,Shogoin Kawahara-cho 54, Sakyo-ku, Kyoto606-8507, Japan (miyatam@kuhp.kyoto-u.ac.jp).Conflict of Interest Disclosures: None reported.Additional Contributions: We thank the patient forgranting permission to publish this information.REFERENCE1.
