Abstract
At the University Eye Hospital of Greifswald, we have developed a digital patient record that allows close monitoring of glaucoma, diabetes and hypertension. The record stores contemporary, long-term profiles containing intraday variation and interaction of intraocular pressure, blood pressure and serum glucose levels even at night. All patients are equipped with a home monitoring system. They subsequently transmit self-measurements via the "telemedical interface" to the server. Physicians use a web front-end to access electronic patient records; this provides a PDF export filter for printing. We intend to include a total number of 120 patients from Mecklenburg-Vorpommern who suffer from glaucoma possibly combined with hypertension/diabetes. This long-term investigation was designed as a randomised cross-over study in two groups. Especially for this project an electronic patient record was developed and implemented. The components of the home monitoring system were modified and connected to a custom-built "telemedical interface". To date the study includes 120 patients, 60 of whom constantly measure and transmit their values to the electronic patient record, while the others are treated without home monitoring. All self-measurements are presented in a tabular form. In addition, dynamically generated graphics provide a diagrammatic view of all values. On demand, a detailed protocol for every single measurement report allows a comprehensive evaluation of the quality of the self-measurements. Ocular perfusion pressure is calculated automatically from intraocular pressure and blood pressure. The presented system documents continuously all information that is relevant for treatment and provides fast access for all attending physicians. Central data collection and unlocalised access improve information exchange between involved physicians. Flexible measurement periods allow the detection of pressure spikes even at night. In addition, this may help to classify glaucoma (normal-pressure glaucoma) and its causal connection to blood pressure. The patients benefit from individualised therapy adaptation and early therapeutic intervention in case of critical parameters.
