We observed 36 patients (37 eyes) with purulent corneal ulcers (PCU) of various etiologies.

The efficiency of M-CXL ranged from 100% to 66.6% depending on depth and width (square area) of the infiltration in question. In cases where infiltration affected the entire stromal thickness, the M-CXL efficacy sharply decreased to 66.6%, even with its small (<6 mm) area. In cases where infiltrations extended to the Descemet’s membrane with an overall area >7 mm, the clinical effect of M-CXL was absent or insufficient.</p></div><div><h3>Conclusion</h3><p>In 75% cases, M-CXL showed complete reduction of PCU. Comparing with control groups, the duration of treatment in the test group decreased 42% (P less than 0.05). In infiltrations over a wide area affecting all the layers up to the Descemet’s membrane, resorbtion of the purulent focus was not achieved. However, it’s spread and purulent fusion were sufficiently suspended, thereby allowing therapeutic penetrating keratoplasty to be performed with a smaller graft diameter.</p></div>","PeriodicalId":100782,"journal":{"name":"Journal of EuCornea","volume":"3 3","pages":"Pages 13-21"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.xjec.2019.12.001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91677893","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}
