Prospective, comparative, and nonrandomized trial.
One hundred patients (60±14 years) with a rhegmatogenous detachment (RD) (symptoms duration: 10±13 days) were treated with a episcleral buckle, cryotherapy, in selected cases , external drainage of subretinal fluid or with a vitrectomy, cryotherapie and a fluid-gas (SF6 30:70) exchange. Mean follow up was 9±6 weeks. Patients had a complete ophthalmic examination, and an optical coherence tomography (OCT). Visual acuity was determined with ETDRS-charts. Complete foveal reattachment after macula-off RD were found in almost all patients treated with vitrectomy (VA improved from 0.08 to 0.25). In patients operated with a buckle VA improved from 0.06 to 0.13, with subfoveal fluid in 50% of the patients.In the macula-on detachment group VA was 0.4 before and after scleral buckling and in the vitrectomy group there was an improvement from 0.2 to 0.32. Subfoveal fluid was found only in some cases in both groups.
Conclusions: Complete foveal reattachment after macula-off RD occurs with vitrectomy more often than with scleral buckling resulting in a better visual acuity. In patients with macula-on detachment visual acuity seems to be better after scleral buckling than after vitrectomy.
