Retinal vessel segmentation is an important tool for the detection of many eye diseases and plays an important role in the automated screening system for retinal diseases. A segmentation algorithm based on a multiscale attentional resolution network is proposed to address the problem of insufficient segmentation of small vessels and pathological missegmentation in existing methods. The network is based on the encoder-decoder architecture, and the attention residual block is introduced in the submodule to enhance the feature propagation ability and reduce the impact of uneven illumination and low contrast on the model. The jump connection is added between the encoder and decoder, and the traditional pooling layer is removed to retain sufficient vascular detail information. Two multiscale feature fusion methods, parallel multibranch structure, and spatial pyramid pooling are used to achieve feature extraction under different sensory fields. We collected the clinical data, laboratory tests, and imaging examinations of JBS patients, extracted the genomic DNA of relevant family members, and validated them by whole-exome sequencing and Sanger sequencing. The patient had diabetes mellitus as the main manifestation, with widened eye spacing, low flat nasal root, hypoplastic nasal wing, and low hairline deformities. Genetic testing confirmed the presence of a c.4463\u2009T\u2009&gt;\u2009C (p.Ile1488Thr) pure missense mutation in the UBR1 gene, which was a novel mutation locus, and pathogenicity analysis indicated that the locus was pathogenic. This patient carries a new UBR1 gene c.4463\u2009T\u2009&gt;\u2009C pure mutation, which improves the clinical understanding of the clinical phenotypic spectrum of JBS and broadens the genetic spectrum of the UBR1 gene. The experimental results showed that the method achieved 83.26% and 82.56% F1 values on CHASEDB1 and STARE standard sets, respectively, and 83.51% and 81.20% sensitivity, respectively, and its performance was better than the current mainstream methods.<\/jats:p>","DOI":"10.1155\/2022\/7414165","type":"journal-article","created":{"date-parts":[[2022,2,16]],"date-time":"2022-02-16T19:05:39Z","timestamp":1645038339000},"page":"1-12","source":"Crossref","is-referenced-by-count":1,"title":["Evaluation of Fundus Blood Flow Perfusion in Patients with Diabetic Retinopathy after PPV with Fundus Color Doppler Based on Big Data Mining"],"prefix":"10.1155","volume":"2022","author":[{"given":"Xin","family":"Wang","sequence":"first","affiliation":[{"name":"Department of Endocrinology, Lianshui County People's Hospital, Huai\u2019an 223400, Jiangsu Province, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fangfang","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, The Affiliated Huai\u2019an Hospital of Xuzhou Medical University, Huai'an Second People\u2019s Hospital, Huai\u2019an 223001, Jiangsu Province, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2434-7810","authenticated-orcid":true,"given":"Weiwei","family":"Zhao","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Hongze District People\u2019s Hospital, Huai\u2019an 223100, Jiangsu Province, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1155\/2021\/6940056"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1155\/2021\/7119779"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.17816\/vto20132033-10"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1097\/01.hjh.0000523774.53704.9a"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1002\/jcu.20650"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1159\/000330509"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1007\/s13139-020-00671-6"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.12659\/msm.883757"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1360\/tb-2019-0864"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1016\/j.neucom.2018.12.021"},{"issue":"6","key":"11","first-page":"102834","article-title":"Wave patterns of (2+1)-dimensional nonlinear Heisenberg ferromagnetic spin chains in the semiclassical limit","volume":"16","author":"G.
