To evaluate optical coherence tomography (OCT), anatomical and functional outcome after scleral buckling surgery (SBS) in macula-off rhegmatogenous retinal detachment (RRD).
Department of Ophthalmology, Baskent University, Faculty of Medicine, Ankara, TURKEY
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.
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).
Severe IS/OS disruption may the most important predictor of postoperative VA after succesfull surgery in macula-off rhegmatogenous retinal detachment.
