Abstract Details

Purpose:

To evaluate optical coherence tomography (OCT), anatomical and functional outcome after scleral buckling surgery (SBS) in macula-off rhegmatogenous retinal detachment (RRD).

Setting:

Department of Ophthalmology, Baskent University, Faculty of Medicine, Ankara, TURKEY

Methods:

Medical charts of 87 patients (87 eyes), who underwent SBS for macula off RRD were retrospectively analysed. Patients with follow-up ≥ 6 months were included. Exclusion criteria were giant retinal tears, retinal dialysis, chorioretinal dystrophies, proliferative vitreoretinopathy ≥ grade-C1, schisis detachment and vitreous opacities. Reattachment success rate, pre- and postoperative visual acuity (VA) were examined. Postoperative spectral-domain (SD)-OCT images were evaluated. The status of photoreceptor inner segment/outer segment (IS/OS) and external limiting memrane (ELM) junction were analysed. Potential risk factors influencing postoperative VA were evaluated by using linear multivariate logistic regression.

Results:

The primary anatomic success rate was 93.8% (81 eyes), final success rate was 98.7% (86 eyes). Preserved -ELM ( OR 0.58, p=0.004) and IS/OS- integrity (OR 0.84, p=0.031), drainage of subretinal fluid (OR 0.42, p<0.0001) were detected as significant independent factors for influencing postoperative VA favourable. Duration of detachment > 6 days (OR 1.46, p=0.04), two/ three retinal breaks (OR 1.30, OR 1.36, p<0.0001) were significant independent risk factors for a poor postoperative VA. Severe IS/OS disruption was the most important risk factor for poor postoperative VA (β 0.724, OR 2.06, p<0.0001).

Conclusions:

Severe IS/OS disruption may the most important predictor of postoperative VA after succesfull surgery in macula-off rhegmatogenous retinal detachment.
