Anatomic and functional prognosis of vitreoretinal surgery in rhegmatogenous retinal detachment associated with intraocular inflammation.

BACKGROUND/OBJECTIVES: The predictive factors of surgical results in uveitic retinal detachment (RD) are lacking. The objective was to study the surgical outcomes and determine the risk factors for surgical failure in rhegmatogenous RD associated with intraocular inflammation (RRDIOI).

METHODS

Retrospective series of consecutive eyes with RRDIOI undergoing vitreoretinal surgery between 2012 and 2019 in two French referral centres. Patients underwent 23- or 25 G pars plana vitrectomy (PPV), scleral buckling (SB), or a combination of both. The main objective was to describe the predictive factors of visual recovery and anatomical success after surgery.

RESULTS

Seventy-one eyes were included. Posterior and panuveitis accounted for 91.5% of eyes. Seventy-five percent of eyes had an infectious cause for their uveitis. The first surgery consisted in PPV alone, SB alone, or both in 87.3%, 4.2% and 8.5% of cases respectively. The reattachment rate was 74.6% after one surgery (100% in case of SB, either alone or in association with PPV). On multivariate analysis, the only predictive factor of visual improvement was a baseline BCVA ≥ 20/400, while the only predictive factor for surgical success at 12 months was the absence of RD recurrence within the first 6 weeks of surgery.

CONCLUSIONS

RRDIOI has a relatively favourable anatomical prognosis. The addition of scleral buckling may be beneficial in selected cases.
