Pars Plana Vitrectomy for Retinal Detachment with Single Break

Primary Indication: Established Retinal Detachment

The presence of a clinical retinal detachment with a documented horseshoe tear constitutes an absolute indication for surgical repair, as nearly all patients with symptomatic clinical rhegmatogenous retinal detachment will progressively lose vision unless the detachment is repaired, according to the American Academy of Ophthalmology 1
More than 95% of uncomplicated rhegmatogenous retinal detachments can be successfully repaired, with better visual outcomes when repaired early and especially before the detachment involves the macula, as recommended by the American Academy of Ophthalmology 1

A horseshoe tear with bridging vessel represents a high-risk configuration where continued vitreous traction may extend the tear beyond treated areas, making complete vitreous removal via PPV advantageous, as indicated by the American Academy of Ophthalmology 2
Symptomatic presentation with acute symptoms confirms this is a symptomatic retinal break caused by vitreoretinal traction, and at least half of untreated symptomatic retinal breaks with persistent vitreoretinal traction will lead to clinical retinal detachment, according to the American Academy of Ophthalmology 1

The American Academy of Ophthalmology guidelines indicate that both PPV and scleral buckling achieve comparable anatomical and visual outcomes for rhegmatogenous retinal detachment, with low to very low certainty evidence indicating little or no difference between the two procedures 3, 4

Prompt intervention is indicated to prevent further vision loss, particularly macular involvement, as the rate of successful reattachment is higher and visual results are better when repaired early, especially before the detachment involves the macula, according to the American Academy of Ophthalmology 1, 6

The most common cause of treatment failure in horseshoe tears is inadequate treatment of the tear, particularly at the anterior border, which reinforces the appropriateness of PPV, allowing complete vitreous removal and direct visualization of the entire tear with adequate treatment margins, as recommended by the American Academy of Ophthalmology 2, 7
