ABSTRACT

Purpose:

To compare the anatomical and functional results and complication rate of 25 gauge pars plana vitrectomy (25g PPV) with expansive gas tamponade for rhegmatogenous retinal detachment (RRD) between experienced and beginner surgeon.

Setting:

Department of Ophthalmology, University Hospital Kralovske Vinohrady, Prague, Czech Republic.

Methods:

Retrospective, comparative, single centre consecutive case series study. Patients with RRD with proliferative vitreoretinopathy (PVR) grade lower than C operated using 25g PPV with expansive gas tamponade between October 2015 and September 2017 were divided into 2 groups. Group 1 was operated by experienced vitreoretinal surgeon, group 2 was operated by 2 beginner surgeons. Anatomical and functional results as well as complication rate were compared between the two groups.

Results:

166 eyes were included in the study. In group 1 (95 eyes), single operation reattachment was achieved in 93 eyes (97,9%), final anatomical success was achieved in 94 eyes (98,9%). Best corrected visual acuity (BCVA) improved from 0,35 Decimal to 0,65 Decimal. In group 2 (71 eyes), single operation reattachment was achieved in 66 eyes (93,0%), final anatomical success was achieved in 71 eyes (100,0%). BCVA improved from 0,29 Decimal to 0,64 Decimal. Most common complication was postoperative intraocular pressure (IOP) elevation of >25 mmHg in 32 eyes (33,7%) and 21 eyes (29,6%) respectively. Other complications were rare and included postoperative intraocular hypotony, epiretinal membrane formation, macular hole formation, haemophthalmus, iatrogenic posterior lens capsule tear and subretinal perfluorocarbon.

Conclusions:

25g PPV with expansive gas tamponade renders excellent anatomical results and improvement in BCVA in RRD. Single operation success rate is high even if performed by beginner surgeon. Complication rate is comparable between experienced and beginner surgeon.
