To describe features of retinal folds and deformation after 23 gauges vitrectomy or scleral buckle surgery for rhegmatogenous retinal detachment, using fundus autofluorescence and macular spectral-domain optical coherence tomography (SD-OCT).
Retrospective interventional case seriesPatients: 150 patients with rhegmatogenous retinal detachment have been includedPrincipals outcomes:1°) Patient, retinal detachment and surgery features2°) Description of rhegmatogenous retinal detachment after surgery: best corrected visual acuity, fundus autofluorescence (heidelberg®), macular spectral-domain optical coherence tomography (SD-OCT) (cirrus®), presence of micropsia or metamorphopsia

Patients with rhegmatogenous retinal detachment frequently describe micropsia, metamorphopsia or uncomplete visual acuity recovery. In our serie, scleral buckle surgery show less hyperfluorescent lines that are parallel the retinal vessels, and best visual acuity outcomes. 23 gauges vitrectomy surgery for retinal detachment are more frequently associated with outer or inner retinal folds and hyperfluorescent lines. Many hypothesis may explain the presence of retinal displacement after surgery such as pre-existing epiretinal membrane, subretinal fluids at the end of surgery, hypotonia with choroidal detachment and vitreous base contraction.
