Gliederung

Text

Purpose: The interaction of vitreous and peripheral retina is closely related to the phathogenesis of vitreo-retinal diseases, however it is very difficult to observe the status of peripheration part of fundus before surgeries. So in this study, we observed the status of peripheral vitreous including vitreous base during a vitrectomy using intraoperative optical coherence tomography (iOCT).

Methods: This study was performed in accordance with the recommendations of the Declaration of Helsinki and approved by the ethics committee of the Yamagata University Faculty of Medicine, Yamagata, Japan. This retrospective study included 20 eyes of 18 subjects with proliferative diabetic retinopathy. The status of peripheral vitreous and its interaction with peripheral retina using iOCT. The subjects were enrolled in this study from December 2015 to March 2016 in Yamagata University Hospital. When the vitreous was shaved with scleral indentation, the status of peripheral vitreous base part was observed by radial 3 mm B-scanning using iOCT RESCAN™ 700 (Carl Zeiss, Germany) of which the images were analyzed postoperatively.

Results: iOCT images enabled to visualize the angle formation of the interation between the periphearal vitreous and retina in all the patients. It was possible to trace the vitreous membrane from posterior pole to the vitreous base. Those findings helped us to perform a periphearal posterior vitreous membrane resection. Any intraoperative adverse events did not occur in all the subjects.

Conclusions: iOCT enables the visualization of the vitreous base during a vitrectomy. It is useful to perform the safe shaving of the vitreous base.
