[Scleral buckling for rhegmatogenous retinal detachment]
Summary
Scleral buckling surgery effectively reattaches the retina in most rhegmatogenous retinal detachment cases, significantly improving visual acuity. Cryosurgery with scleral buckling is considered a gold standard for phakic eyes, though vitreous traction can cause re-detachment.
Area of Science:
- Ophthalmology
- Retinal Surgery
Background:
- Rhegmatogenous retinal detachment (RRD) involves sensory retina separation from the RPE due to retinal tears and vitreoretinal traction.
- Current treatment for symptomatic RRD is exclusively surgical, with options including intraocular and extraocular procedures.
Purpose of the Study:
- To evaluate the outcomes of scleral buckling surgery for rhegmatogenous retinal detachment.
- To assess the efficacy of cryosurgery combined with scleral buckling in phakic eyes.
Main Methods:
- Retrospective evaluation of 17 eyes with RRD treated with scleral buckling.
- Procedures included radial plombage or cerclage, often with cryocoagulation and occasional gas tamponade.
Main Results:
- Primary retinal reattachment achieved in 94% of cases; 82.4% remained flat post-surgery.
- Postoperative visual acuity significantly improved (p=0.01), with an average Snellen equivalent of 20/50.
- Failure was linked to persistent vitreous traction and proliferative vitreoretinopathy (PVR).
Conclusions:
- Scleral buckling, particularly cryosurgery for phakic eyes, is effective for uncomplicated RRD.
- The technique demonstrates significant visual acuity improvement.
- Persistent vitreous traction and PVR remain key challenges impacting surgical success.
