After obtaining informed consent each patient underwent OCT examination, usually one day before elective orthopaedic surgery (knee replacement). The OCT examination was repeated after the surgery. Both eyes were examined separately. After obtaining data the investigators compared the difference.
Detailed description
Inclusion and exclusion criteria evaluated during the pre-anesthesia visit. After obtaining informed consent, patients were referred to OCT examination in the Ophthalmology clinic. The examination was performed in the 48 hours before the surgery. Between the fourth and the seventh postoperative day, the patients underwent control OCT examination. The results of OCT examinations, baseline clinical data and the data on the course of surgery and postoperative care were recorded for further analysis.
