Abstract

Aim: To evaluate the advantages and safety of vitrectomy under air for treating macula-involving rhegmatogenous retinal detachment (RRD).

Methods: Consecutive patients with macula-involving RRD who underwent vitrectomy under air were recruited. Demographic and clinical data were: age, gender, eye, lens status, best corrected visual acuity (BCVA) in logarithm of the minimum angle of resolution (logMAR), axial length, intraocular pressure (IOP). RRD parameters were: RRD extent, retinal breaks number. Surgical data were: cataract surgery, tamponade used. Postoperative parameters were: BCVA, IOP at first, third, sixth month, recurrent RD, incidence of retinal folds, subretinal fluid (SRF) persistence, macular displacement.

Results: Seventy-one eyes (71 patients) were recruited. Cataract surgery was performed in 32 of 45 phakic patients. The tamponade used was: sulfur hexafluoride 18% (41), silicon oil (SO) (26), high-density SO (4). BCVA improved significantly from baseline (1.2 ± 0.4 logMAR) to the last control (0.8 ± 0.7 logMAR) (P = 0.03285). Recurrent RD incidence was 14.1%. Postoperative complications were: retinal folds (2), SRF persistence (3), macular displacement (2).

Conclusion: Vitrectomy under air is a safe alternative technique for treating macula-involving RRD. Vitrectomy under air allows surgeon to remove accurately the vitreous from the peripheral retina and facilitates the removal of SRF reducing the complications related to its postoperative persistence.
