It is important to differentiate PCV from typical nAMD as there are differences in treatment response between subtypes. Indocyanine green angiography (ICGA) is the gold standard for diagnosing PCV; however, ICGA is an invasive detection method and impractical for extensive use for regular long-term monitoring. In addition, access to ICGA may be limited in some settings. The purpose of this review is to summarize the utilization of multimodal imaging modalities (color fundus photography, optical coherence tomography (OCT), OCT angiography (OCTA), and fundus autofluorescence (FAF)) in differentiating PCV from typical nAMD and predicting disease activity and prognosis. In particular, OCT shows tremendous potential in diagnosing PCV. Characteristics such as subretinal pigment epithelium (RPE) ring-like lesion, en face OCT-complex RPE elevation, and sharp-peaked pigment epithelial detachment provide high sensitivity and specificity for differentiating PCV from nAMD. With the use of more practical, non-ICGA imaging modalities, the diagnosis of PCV can be more easily made and treatment tailored as necessary for optimal outcomes.<\/jats:p>","DOI":"10.3390\/diagnostics13101680","type":"journal-article","created":{"date-parts":[[2023,5,10]],"date-time":"2023-05-10T01:40:02Z","timestamp":1683682802000},"page":"1680","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["New Concepts for the Diagnosis of Polypoidal Choroidal Vasculopathy"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0487-5950","authenticated-orcid":false,"given":"Jinzhi","family":"Zhao","sequence":"first","affiliation":[{"name":"Singapore Eye Research Institute, Singapore National Eye Centre, Singapore 168751, Singapore"},{"name":"Tianjin Medical University Eye Hospital, Tianjin 300392, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2393-1329","authenticated-orcid":false,"given":"Priya R","family":"Chandrasekaran","sequence":"additional","affiliation":[{"name":"Singapore Eye Research Institute, Singapore National Eye Centre, Singapore 168751, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kai Xiong","family":"Cheong","sequence":"additional","affiliation":[{"name":"Singapore Eye Research Institute, Singapore National Eye Centre, Singapore 168751, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mark","family":"Wong","sequence":"additional","affiliation":[{"name":"Singapore Eye Research Institute, Singapore National Eye Centre, Singapore 168751, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kelvin","family":"Teo","sequence":"additional","affiliation":[{"name":"Singapore Eye Research Institute, Singapore National Eye Centre, Singapore 168751, Singapore"},{"name":"Ophthalmology & Visual Sciences Academic Clinical Program (Eye ACP), Duke-NUS Medical School, Singapore 169857, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,5,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1097\/00006982-199010010-00001","article-title":"Ideopathic polypoidal choroidal vasculopathy (IPCV)","volume":"10","author":"Yannuzi","year":"1990","journal-title":"Retina"},{"key":"ref_2","first-page":"359","article-title":"Polypoidal Choroidal Vasculopathy: An Update on Therapeutic Approaches","volume":"8","author":"Wong","year":"2013","journal-title":"J.
