Peritomy-sparing scleral buckle

To introduce a modified technique for encircling circumferential scleral buckling without peritomy thorough a small conjunctival opening for the repair of uncomplicated rhegmatogenous retinal detachment (RD).

This technique was performed in 10 eyes of 10 patients with primary rhegmatogenous RD who underwent encircling circumferential scleral buckling without peritomy. Transconjunctival traction sutures were placed in four rectus muscles. After transconjunctival location of the retinal break, a 5- to 6-mm radial conjunctival incision was performed in 4 quadrants without cutting the limbal conjunctiva-Tenon's capsule. A 240-silicone band in scleral belt loops was used for an encircling circumferential buckle. After drainage and cryopexy, SF6 was used for tamponade. The incision was closed via layered closure only ocassionally.

Primary attachment success of 100% was achieved by single procedure. The intraoperative and postoperative complications observed included subconjunctival hemorrhage observed in 5 (50%) of eyes. These disappeared in the postoperative period.

Minimal conjunctival incision in scleral buckle without peritomy can achieve excellent anatomical success in patients with rhegmatogenous RD without distorting ocular surface anatomy. This is the first description of technique preserving corneal limbus anatomy that could convert buckling surgery to more attractive option for retina surgeons.
