Although the mean total number of injections was similar between groups, the requirement for adjuvant steroid treatment was significantly higher in ranibizumab group, which may affect the number of visits and treatment costs. Both ranibizumab and aflibercept treatments achieved a good long-term visual and anatomical response in DME patients.</p>","PeriodicalId":23054,"journal":{"name":"Therapeutic Advances in Ophthalmology","volume":"15 ","pages":"25158414231195174"},"PeriodicalIF":2.5,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/26/23/10.1177_25158414231195174.PMC10464826.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10127491","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
