Electronic Health Records (EHRs) are an essential element in telemedicine and service applications. They are longitudinal electronic records of patient health information generated by one or more encounters in any care delivery setting. EHR can reduce medical errors and costs. They are believed to increase physician efficiency. EHR standardization is an important aspect to exchange health information. Health Level 7 - Clinical Document Architecture (HL7-CDA) and Digital Imaging and Communications in Medicine (DICOM) standards are intensively influencing in this standardization process. This paper presents a web-based application (TeleOftalWeb 3.2) to store and exchange EHRs in ophthalmology by using HL7-CDA and DICOM standards. The application manages an Extensible Markup Language (XML) native database with information about patients and their eyes fundus photographs in different kind of formats (DICOM, JPEG, GIF and others). Its architecture is a three-layered and it uses two databases: dbXML 2.0 and MySQL 5.0. EHR can be stored and viewed in different formats such as XML, Hypertext Markup Language (HTML) and Portable Document format (PDF).
