Giant retinal tear
Retina & Vitreous
Key Points
- •Giant retinal tear is a full-thickness break ≥90° (3 clock hours) with characteristic retinal flap inversion; accounts for ~1.5% of all RRD; high PVR risk (~12–41%)
- •Key associations: Stickler syndrome (bilateral retinal detachment risk up to 70%, bilateral GRT risk lower, COL2A1), Marfan syndrome, high myopia (~30–40%), and blunt trauma (~10–15%)
- •Surgical management: PPV + PFCL (to unfold inverted flap) + 360° endolaser + silicone oil tamponade (preferred for most GRTs); primary anatomical success ~85–90%
- •Fellow eye must always be examined - prophylactic 360° retinopexy recommended in hereditary cases; bilateral GRT risk is ~12–15% overall
- •PFCL is the critical intraoperative tool - heavier than water (SG ~1.76–1.94), flattens retina posteriorly-to-anteriorly, unfolds the inverted flap; must be completely removed (retinal toxicity if retained)
