To evaluate postoperative outcome after 23-gauge vitrectomy with endotamponade in patients with pseudophakic rhegmatogenous retinal detachment.
Prospective, non-randomised clinical study. Department of Ophthalmology, Medical University of Vienna
55 patients who underwent pseudophakic rhegmatogenous retinal detachment surgery with vitrectomy and endotamponade were included into this study. Patients were followed up up to 1 year. The main study outcomes were the visual acuity, surgical complications and the re-surgery rate.
Fovea-off retinal detachment was detected in 31 eyes (58%) of all patients preoperatively. A proliferative vitreoretinopathy stage B or C could be observed in 24 eyes (43%). For endotamponade 16% C3F8-gas was used in 73%, 20% SF6-gas in 22% and 16% C2F6-gas in 5% of the patients. In 62% an endolaser was performed during the surgery. In 4 patients a subretinal membrane blue technique was used to find the retinal break. The mean follow-up period was 5.7 months (up to 12 months). After one year of follow-up visual acuity statistical significant increased from 1.0 logMar to 0.1 logMar (p<0.01). In 48 out of these 55 (87%) patients retinal attachment could be achieved after the first surgery treatment whereas in 7 of 55 (13%) patients a second surgery was necessary due to re-detachment of the retina. Analysis of optical coherence tomography showed development of epiretinal membrane in 13 eyes (24%) after a mean time of 5.5 4.2 months.
This study shows the effectiveness and safety of 23-gauge vitrectomy and gas tamponade. This treatment is associated with good visual and anatomical outcome while the re-operation and complication rate remains low.
