Objective: To identify anatomofunctional changes after pars plana vitrectomy to treat rhegmatogenous retinal detachment.
Methods: An analytical, prospective longitudinal study was performed on 164 eyes of 162 new patients with rhegmatogenous retinal detachment treated by pars plana vitrectomy at the Cuban Institute of Ophthalmology Ramón Pando Ferrer in 2020. There was a group of 135 eyes with vitrectomy-oil and another of 29 with vitrectomy-gas C3F8. They were followed up to one year after the primary operation.
Results: The mean age was 59 years (SD ± 10). Males predominated (66 %, n = 108). The anatomic success rate with a single operation was 59.1 %. Retinal reapplication was achieved in 92 % (n = 151) and 93.3 % (n = 153) achieved macular reapplication at one year. Final best-corrected visual acuity was higher in gas-operated [0.52 LogMAR (RI 0.30, 0.70)], p = 0.027; in those with global initial applied macula [0.22 LogMAR (RI 0.15, 0.26)], p < 0.001 (was similar in both groups) and in those with vitrectomy-oil without preoperative proliferative vitreoretinopathy [0.52 LogMAR (RI 0.30, 1.23)]; p < 0.001.
Conclusions: In most patients vitrectomized for retinal detachment, anatomic success was achieved at 1 year with a single surgical intervention. Greater visual recovery was obtained in the vitrectomy plus gas group, in those treated by oil vitrectomy without preoperative vitreoretinopathy and in those with macula initially applied.
