Abstract
Purpose: :
To evaluate the anatomical and functional outcome in patients who underwent retinal detachment surgery and the incidence of associated factors related with surgical failure.
Methods: :
Retrospective, non-comparative case series. One hundred and one eyes of 99 patients with retinal detachment of medium complexity were included. 64 males and 35 females, mean age 62,5 +/- 12,8 years.Patients were splited in two different groups depending on the surgical technique: vitrectomy group (PPV) 37 eyes, and scleral buckling group (SB) 64 eyes. In the PPV group, a subgroup of 10 eyes underwent only pars plana vitrectomy (oPPV) and 27 a combination of both techniques, VPP with scleral buckling (PPV+SB). 26,56% (17/64) in the SB group, 40% (4/10) in the oPPV group and 40.74% (11/27) in the PPV + SB group were pseudophakic. Mean follow up time was 18,4 month +/- 8,3. We evaluated pre-and post-surgical best corrected visual acuity (BCVA), retinal attachment after 30 days of the first surgery, and risk factors for retinal redetachment in all groups.
Results: :
Only with one surgical procedure performed, the PPV group anatomical success was achieved in 78.4% (29/37). 77.78% (21/27) in PPV with scleral buckling and 80% (8/10) in the PPV. In the SB group the retina was attached within the first surgical procedure in 68.75% (44/64), while 31.25% (20/64) required another surgical procedure. According to the lens status in the cases that required additional surgery: 35% of the SB group (7/20) and 37.5% in the PPV group were pseudophakic. The main cause of retinal redetachment was proliferative vitreoretinopathy (PVR) that was present in the 87,5% (7/8) in the PPV group, and in the 65 % (13/20) in the SB group. The final BCVA was 0.57 +/- 0.27 in the PPV group and 0.44 +/- 0.29 in the SB group (decimal scale).
Conclusions: :
Vitrectomy alone or combined with other procedures shows better anatomical outcomes and functional results compared to scleral buckling alone.
