Abstract
BACKGROUND
Pars plana vitrectomy (ppV) combined with silicone oil tamponade is a standard technique in the treatment of complicated retinal detachment. There are still recurrent cases of retinal detachment after silicone oil removal or redetachment with in situ oil tamponade.
OBJECTIVE
The aim was to identify possible risk factors for retinal redetachment and to use the knowledge for optimizing treatment.
METHODS
Analysis of data from patients who were treated with ppV and silicone oil tamponade in the University Department of Ophthalmology in Marburg during 2010-2015 and who had a retinal redetachment during this period. The results were divided into two groups, redetachment with oil in situ and redetachment after oil removal.
RESULTS
A total of 43 cases (15.6%) had a redetachment, which included 22/43 cases (50%) with a redetachment after oil removal and 21/43 cases (50%) with redetachment with oil in situ. The cause for the renewed detachment was given as proliferative vitreoretinopathy (PVR) in 90.6% (39/43) of the cases, new foramina in 20.9% (9/43) and persisting foramina in 25.5% (11/43).
CONCLUSION
Vitreoretinal scar formation (PVR reaction) was the main risk factor for renewed retinal detachment. Persisting foramina were also named as a frequent cause. Recurrent retinal detachment represents a significant challenge for vitreoretinal surgeons and for the patients considering the economic and emotional burden due to multiple interventions.
