Trainees viewed 3D and 2D surgical videos of pediatric PFV in a randomized order and immediately completed a questionnaire to provide educational assessments.\nRESULTS: Twelve trainees viewed 9 paired 3D and 2D surgical videos from 9 pediatric PFV patients (9 3D videos and 9 2D videos), resulting in 216 completed questionnaires. For pediatric PFV cases, trainees demonstrated a higher accuracy rate when watching 3D surgical videos compared to 2D surgical videos in discerning the depth of the anterior chamber (85.2% vs 70.4%, \u03c7\u00b2=6.857, P=0.009), the location of lens opacity (86.1% vs 69.4%, \u03c7\u00b2=8.679, P=0.003), and vitreous strips (89.8% vs 78.7%, \u03c7\u00b2=5.027, P=0.025). Trainees believed that, compared to 2D surgical videos, 3D surgical videos significantly improved their ability to discriminate shallow anterior chambers (5.70\u00b11.58 vs 3.92\u00b11.14, P&amp;#x003C;0.001), the location of lens opacity (6.80\u00b11.60 vs 4.36\u00b11.35, P&amp;#x003C;0.001), vitreous strips (9.06\u00b12.02 vs 7.16\u00b12.42, P&amp;#x003C;0.001), complicated tractional retinal detachment (9.31\u00b12.13 vs 7.99\u00b12.63, P&amp;#x003C;0.001), and macular involvement (8.47\u00b12.62 vs 6.91\u00b12.84, P&amp;#x003C;0.001) in pediatric PFV cases. Trainees found 3D surgical videos to be significantly more satisfactory than 2D surgical videos in terms of image magnification (8.90\u00b11.61 vs 7.17\u00b11.65, P&amp;#x003C;0.001), clarity (9.21\u00b12.11 vs 7.42\u00b12.27, P&amp;#x003C;0.001), and depth of field (8.31\u00b12.38 vs 6.78\u00b12.79, P&amp;#x003C;0.001). Trainees regarded 3D surgical videos as significantly more suitable for ophthalmic surgical teaching (9.23\u00b10.83 vs 5.75\u00b10.93, P&amp;#x003C;0.001) and implementation (8.83\u00b12.69 vs 6.15\u00b12.83, P&amp;#x003C;0.001) compared to 2D surgical videos.\nCONCLUSION: 3D-display surgical videos offer superior educational benefits for trainees earning pediatric PFV vitrectomy surgery compared to 2D videos.<\/jats:p>","DOI":"10.18240\/ijo.2026.09.14","type":"journal-article","created":{"date-parts":[[2026,8,14]],"date-time":"2026-08-14T06:15:08Z","timestamp":1786688108000},"page":"1785-1791","source":"Crossref","is-referenced-by-count":0,"title":["Utility of 3D-display surgical videos for better educational effects in pediatric persistent fetal vasculature for trainees"],"prefix":"10.18240","volume":"19","author":[{"name":"Beijing Tongren Eye Center, Beijing Tongren Hospital, Capital Medical University, Beijing Ophthalmology and Visual Sciences Key Laboratory, Beijing 100730, China;Co-first Authors: Jing-Hua Liu and Ming-Zhen Yuan","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jing-Hua","family":"Liu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Song-Feng","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Beijing Tongren Eye Center, Beijing Tongren Hospital, Capital Medical University, Beijing Ophthalmology and Visual Sciences Key Laboratory, Beijing 100730, China;Co-first Authors: Jing-Hua Liu and Ming-Zhen Yuan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guang-Da","family":"Deng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Beijing Tongren Eye Center, Beijing Tongren Hospital, Capital Medical University, Beijing Ophthalmology and Visual Sciences Key Laboratory, Beijing 100730, China;Co-first Authors: Jing-Hua Liu and Ming-Zhen Yuan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jing","family":"Ma","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Beijing Tongren Eye Center, Beijing Tongren Hospital, Capital Medical University, Beijing Ophthalmology and Visual Sciences Key Laboratory, Beijing 100730, China;Co-first Authors: Jing-Hua Liu and Ming-Zhen Yuan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liang","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Beijing Tongren Eye Center, Beijing Tongren Hospital, Capital Medical University, Beijing Ophthalmology and Visual Sciences Key Laboratory, Beijing 100730, China;Co-first Authors: Jing-Hua Liu and Ming-Zhen Yuan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tian-Yu","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Beijing Tongren Eye Center, Beijing Tongren Hospital, Capital Medical University, Beijing Ophthalmology and Visual Sciences Key Laboratory, Beijing 100730, China;Co-first Authors: Jing-Hua Liu and Ming-Zhen Yuan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hai","family":"Lu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Beijing Tongren Eye Center, Beijing Tongren Hospital, Capital Medical University, Beijing Ophthalmology and Visual Sciences Key Laboratory, Beijing 100730, China;Co-first Authors: Jing-Hua Liu and Ming-Zhen Yuan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"7543","container-title":["International Journal of Ophthalmology"],"original-title":[],"link":[{"URL":"https:\/\/www.ijo.cn\/gjyken\/article\/pdf\/20260914","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,14]],"date-time":"2026-08-14T06:15:12Z","timestamp":1786688112000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ijo.cn\/gjyken\/article\/abstract\/20260914"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,9,18]]},"references-count":0,"journal-issue":{"issue":"9","published-print":{"date-parts":[[2026,9,18]]}},"URL":"https:\/\/doi.org\/10.18240\/ijo.2026.09.14","relation":{},"ISSN":["2222-3959","2227-4898"],"issn-type":[{"value":"2222-3959","type":"print"},{"value":"2227-4898","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,9,18]]}}}
