Methods: A prospective interventional study including patients with primary RRD undergoing the TSCB technique. The technique consisted of a transconjunctival approach using an olive tip handled cannula with an Atkinson 25-gauge needle tip that injects a high-purity gel in the suprachoroidal space (SCS) and creates a buckle effect that lasts for 12–18 months. Indirect laser retinopexy is done in the operating room or in the early post-operative office visit on the slit lamp. The TSCB technique could be done in the office in selected cases of uncomplicated RRD. Results: The study included 31 eyes of 31 patients. Seventeen eyes were phakic (55%). The RRD involved one quadrant in 81% of eyes. Sixteen eyes (52%) had more than one break. The TSCB procedure was performed in the operating room in 21 patients (68%). The mean duration of follow-up was 5 months. Postoperatively, we achieved retinal attachment in all patients. Three patients (10%) needed a second surgery. Two patients (6%) developed dot hemorrhage due to choroidal puncture. Conclusion: The TSCB is safe, and avoids the complications of conventional scleral buckling.
