ABSTRACT
Objective. To evaluate the utility of intraoperative OCT and its influence on the surgeon's decision during vitreoretinal surgery. Methods. This was a pilot, prospective case series conducted at a tertiary care ophthalmology department in Lahore, Pakistan. Sixteen patients undergoing vitreoretinal surgeries were included using the Leica Enfocus microscope integrated intraoperative optical coherence tomography (IOCT). We also investigated the changes in surgical decision making based on the findings revealed by IOCT using a questionnaire. Results. 16 patients with a mean age of 40.6 ± 19.0 (range: 11-66) years, were included in the study; one case of acute postoperative endophthalmitis could not be imaged. The surgeon had to modify surgical decisions in four (26.7%) cases. IOCT clearly delineated various tissue planes for efficient and safe surgical dissection in pathologies such as posterior vitreous detachment, vitreomacular traction and epiretinal membranes. Furthermore, it also helped identifying perfluorocarbon-retina interface. Conclusions. The intraoperative OCT modality is a feasible and useful intraoperative imaging technique for various kinds of vitreoretinal disorders. The decision making of the surgeon was modified in a quarter of the cases after the use of this newer modality.
