Scleral buckling
Retina & Vitreous
Key Points
- •Scleral buckling is an extraocular technique using silicone elements to indent the sclera, closing retinal breaks and relieving vitreoretinal traction; single-operation success ~85–90% for uncomplicated RRD
- •Ideal candidates: young phakic patients, retinal dialysis, inferior breaks, single/few identifiable breaks, PVR ≤ grade B - avoids cataract formation seen with PPV
- •Most common cause of failure is a missed retinal break - thorough 360° indirect ophthalmoscopy with scleral indentation is essential; excessive cryotherapy increases PVR risk
- •Key complications: myopic shift (1–3D with encircling buckle), buckle extrusion (~3–5%), choroidal detachment (~15–20%), PVR (~5–10%), diplopia (~5–10%)
- •SPR study: SB and PPV have comparable outcomes for phakic patients with medium-complexity RRD - SB preserves the natural lens and avoids cataract
