Corneal keratometry parameters were measured using IOLMaster or a handheld keratometer. Differences in CA between the affected and fellow eyes were analyzed in 52 unilateral PFV patients with available examination data.\nRESULTS: Totally 133 patients diagnosed with PFV were retrospectively reviewed. The male-to-female ratio was 73\/60. Median age at surgery was 38.03mo (interquartile range 58.27mo). Among the PFV patients, 32 (24.06%) had anterior PFV, 2 (1.50%) had posterior PFV, and 99 (74.44%) had combined anterior-posterior PFV. Mild combined PFV was the most common subtype. In unilateral PFV cases, the mean CA in the affected eye was 2.29\u00b11.11 D, and 59.62% (31 eyes) had CA\u22652.0 D. The mean CA in the affected eyes was significantly higher than in the fellow eyes (1.37\u00b10.77 D; P&lt;0.001). Among PFV-affected eyes with CA\u22652.0 D, the steepest corneal meridian was vertically oriented in 30 cases (96.77%), while only 1 case (3.23%) had the steepest meridian oriented horizontally.\nCONCLUSION: In children with unilateral PFV, CA is significantly higher in the affected eyes than in the fellow eyes, and the steepest corneal meridian was predominantly oriented vertically.<\/jats:p>","DOI":"10.18240\/ijo.2026.02.16","type":"journal-article","created":{"date-parts":[[2026,2,12]],"date-time":"2026-02-12T08:00:16Z","timestamp":1770883216000},"page":"333-338","source":"Crossref","is-referenced-by-count":0,"title":["Subtypes and corneal astigmatism in pediatric persistent fetal vasculature"],"prefix":"10.18240","volume":"19","author":[{"name":"Eye Institute and Department of Ophthalmology, Eye &amp; ENT Hospital, Fudan University, Shanghai 200031, China; NHC Key Laboratory of Myopia and Related Eye Diseases; Key Laboratory of Myopia and Related Eye Diseases, Chinese Academy of Medical Sciences, Shanghai 200031, China","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shao-Hua","family":"Zhang","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ying-Ying","family":"Hong","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Eye Institute and Department of Ophthalmology, Eye &amp; ENT Hospital, Fudan University, Shanghai 200031, China; NHC Key Laboratory of Myopia and Related Eye Diseases; Key Laboratory of Myopia and Related Eye Diseases, Chinese Academy of Medical Sciences, Shanghai 200031, China","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yi","family":"Lu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Eye Institute and Department of Ophthalmology, Eye &amp; ENT Hospital, Fudan University, Shanghai 200031, China; NHC Key Laboratory of Myopia and Related Eye Diseases; Key Laboratory of Myopia and Related Eye Diseases, Chinese Academy of Medical Sciences, Shanghai 200031, China","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ying-Hong","family":"Ji","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Eye Institute and Department of Ophthalmology, Eye &amp; ENT Hospital, Fudan University, Shanghai 200031, China; NHC Key Laboratory of Myopia and Related Eye Diseases; Key Laboratory of Myopia and Related Eye Diseases, Chinese Academy of Medical Sciences, Shanghai 200031, China","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7543","container-title":["International Journal of Ophthalmology"],"original-title":[],"link":[{"URL":"https:\/\/www.ijo.cn\/gjyken\/article\/pdf\/20260216.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,2,12]],"date-time":"2026-02-12T08:00:20Z","timestamp":1770883220000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ijo.cn\/gjyken\/article\/abstract\/20260216"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,2,18]]},"references-count":0,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2026,2,18]]}},"URL":"https:\/\/doi.org\/10.18240\/ijo.2026.02.16","relation":{},"ISSN":["2222-3959","2227-4898"],"issn-type":[{"value":"2222-3959","type":"print"},{"value":"2227-4898","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,2,18]]}}}
