According to the anatomical classification based on OCT, 27 eyes (53%) were diagnosed with type 1 CNV, and 24 eyes (47%) were type 2 CNV. Type 2 CNV was characterized by smaller flow area, smaller greatest vascular caliber (GVC), smaller greatest linear dimension (GLD), and shorter duration of disease. The duration of disease only correlated with GVC (&lt;i&gt;p&lt;\/i&gt; = 0.026) in multivariate linear regression results. Meanwhile, GLD correlated with GVC and flow area whereas GVC was not associated with flow area. &lt;b&gt;&lt;i&gt;Conclusion:&lt;\/i&gt;&lt;\/b&gt; This study demonstrated that type 2 CNV was characterized by shorter duration of disease, smaller GVC, smaller GLD, and smaller flow area compared with type 1 CNV. Additionally, we showed that the duration of the disease correlated with GVC of the CNV.<\/jats:p>","DOI":"10.1159\/000497491","type":"journal-article","created":{"date-parts":[[2019,6,13]],"date-time":"2019-06-13T21:00:32Z","timestamp":1560459632000},"page":"178-186","source":"Crossref","is-referenced-by-count":7,"title":["The
