Abstract
Purpose :
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).
Methods :
Retrospective interventional case series
Patients: 150 patients with rhegmatogenous retinal detachment have been included
Principals outcomes:
1°) Patient, retinal detachment and surgery features
2°) 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
Results :
1°) Patient, retinal detachment and surgery features
Mean age: 66,2 ± 3,1 years old, quadrants of retinal detachment: 2,5 ± 0,9, one month intraocular pressure 18 ± 6 mmHg, macular off status 115 patients
23 gauges vitrectomy surgery: 89 patients, gas tamponade for 75 patients and silicon oil tamponade for 14 patients
scleral buckle surgery: 61 patients
2°) Description of rhegmatogenous retinal detachment after surgery
1 month best corrected visual acuity: 0,31 log MAR
hyperfluorescent lines that are parallel the retinal vessels: 32,8 ± 6 %
outer retinal fold seen with oct: 25 ± 7%
micropsia or metamorphopsia: 55 ± 5 %
Conclusions :
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.
