Intraoperative optical coherence tomography (I-OCT) assisted passage of the encircling element during retinal detachment surgery.

Objective: To describe the role of microscope integrated optical tomography (Mi-OCT) in passage of the encircling element during retinal detachment surgery. Materials and methods: Mi-OCT was switched on while passing scleral anchoring sutures to secure the encircling element. The depth of the suture tract was seen in real time while the needle was passed through the sclera. The amount of scleral intend achieved was assessed using Mi-OCT at the end of the surgery. Results: The depth of needle tract through the sclera and the amount of scleral indentation achieved while tying the sutures could be successfully analyzed using Mi-OCT. Conclusion: Mi-OCT can be used as an adjunct while training vitreoretinal fellows and trainees in surgical procedures like passage of scleral sutures for anchoring the encircling element.
