This study evaluated VD change after exercise in HF-pEF, accounting for signal strength.Patients and methods: Patients with HFpEF underwent 3 × 3-mm OCTA before and after a 6-minute walk test. Change in parafoveal VD in superficial (SCP) and deep (DCP) capillary plexuses was modeled with and without adjustment for signal strength index (SSI) and between New York Heart Association (NYHA) functional classes.Results: Among 34 eyes (20 subjects), unadjusted DCP VD increased after exercise (1.27; 95% CI, 0.31 to 2.24; P = .010), more so in NYHA class III than I or II (difference, 2.39; 95% CI, 0.86 to 3.91; P = .002). SSI adjustment attenuated estimates to nonsignificance (overall, 0.48; 95% CI, -0.23 to 1.19; P = .19; NYHA difference, 0.75; 95% CI, -0.65 to 2.16; P = .29). SCP changes were nonsignificant.Conclusion: Postexercise VD changes in HFpEF were largely explainable by signal strength changes. OCTA analyses should adjust for signal strength to distinguish measurement artifact from true vascular differences.","PeriodicalId":19679,"journal":{"name":"Ophthalmic surgery, lasers & imaging retina","volume":" ","pages":"512-522"},"PeriodicalIF":1.1,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148605949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A 6-year-old girl initially presented with unilateral blurred vision and was diagnosed with WMS due to a retinal AVMs in her left eye. Initial brain magnetic resonance imaging (MRI) showed no intracranial AVMs. At routine follow-up, she had developed headaches and nausea after 4 years, leading to diagnosis of a cerebral AVM, treated with Gamma Knife radiosurgery. Concurrently, fundus examination revealed progressive retinal AVM changes, accompanied by decreased best-corrected visual acuity and worsened optical coherence tomography findings. The parallel progression of retinal and cerebral AVMs highlights the dynamic nature of vascular malformations in WMS. This case underscores that vascular anomalies in WMS may evolve over time and may not remain isolated to a single organ. Progressive retinal AVM changes can signal potential cerebral involvement. Therefore, any ocular progression in WMS warrants timely neuroimaging, even if previous scans were normal. Reporting such rare cases can aid in improving early diagnosis and follow-up strategies in WMS.","PeriodicalId":19679,"journal":{"name":"Ophthalmic surgery, lasers & imaging retina","volume":" ","pages":"465-467"},"PeriodicalIF":1.1,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148278253","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Custom-length needles (0.5-1.5 mm) were selected accordingly. SC injections were performed under UBM guidance, with imaging confirming entry and injectate spread.Results: UBM confirmed successful SC injection in all specimens, with hypoechoic separation between sclera and choroid. Post-injection, scleral thickness increased significantly (1.13 ± 0.13 mm to 2.28 ± 0.19 mm, P < .0001), validating drug delivery.Conclusion: UBM-guided needle selection enables accurate SC injection and may reduce failed attempts.
