Abstract
BACKGROUND AND OBJECTIVE
To describe a series of patients with inferior retinal detachments managed with primary 25-gauge pars plana vitrectomy (PPV), 2 to 3 weeks of postoperative perfluoro-n-octane (MT-PFO) tamponade, and upright positioning followed by secondary PPV and PFO removal.
PATIENTS AND METHODS
Interventional case series of 157 patients with inferior retinal detachments with and without proliferative vitreoretinopathy. Eyes were treated with 25-gauge PPV, endophotocoagulation, and MT-PFO tamponade. Patients underwent postoperative upright positioning followed by repeat PPV and PFO removal in a planned, staged procedure.
RESULTS
Mean follow-up was 32 ± 4.6 months. Successful reattachment was achieved in 87.5% of 159 eyes. Main initial postoperative complications were persistent intraocular pressure (IOP) elevation in 34% (n = 54), excessive inflammation in 27% (n = 43), and PFO in the anterior chamber in 21% (n = 34). Additional complications occurring after PFO removal included cataract surgery in 16% (n = 22) of initially phakic eyes, redetachment in 13% (n = 21), and need for filtering surgery in 6% (n = 10). Logistic regression analysis revealed macula status (P = .003) and progression to filtering surgery (P = .001) as significant factors predicting visual outcome at 1-year follow-up.
CONCLUSION
MT-PFO tamponade and upright head positioning may be efficacious for inferior retinal detachment repair in patients unable to assume face-down postoperative positioning. Anatomic and visual outcomes are similar to previously described reattachment procedures. A characteristic granulomatous inflammatory reaction presents in some patients, but does not appear to leave long-term visual or anatomic sequelae. Persistent IOP elevation and progression to filtering surgery may occur in a small percentage of patients and portends a worse visual outcome.
