Abstract

Purpose: To evaluate and characterize the micro-structural retinal changes present on spectral-domain optical coherence tomography imaging (SD-OCT) in eyes that have undergone pars plana vitrectomy and silicone oil (SO) tamponade for various clinical conditions.

Methods: We conducted a retrospective, consecutive case series study of patients who underwent pars plana vitrectomy with SO tamponade for tractional retinal detachment, rhegmatogenous retinal detachment, or proliferative vitreoretinopathy and had SD-OCT performed both during SO tamponade and after SO removal. Presence of subretinal fluid (SRF), intraretinal cysts (IRC), epiretinal membrane (ERM), ellipsoid zone and external limiting membrane disruption (EZD, ELMD), macular hole (MH), hyperreflective opacities (HO), central foveal thickness (CFT) and choroidal thickness (CT) were documented. Duration of SO tamponade was also noted, along with timing of SD-OCTs in relation to SO tamponade and removal. Lens status was documented along with incidence of ERM peeling at the time of SO removal.

Results: Six eyes from six patients met all inclusion criteria. Average time of SO tamponade was 7.32 months or 223.67 days. Average time SD-OCT was performed after SO tamponade was 126.25 days. Average time SD-OCT was performed after SO removal was 436.1 days. While under SO tamponade, IRC were noted in 3/6 (50%) eyes, SRF in 2/6 (33%) eyes, EZD in 5/6 (83.3%) eyes, ELMD in 5/6 (83.3%) eyes, and HO in 3/6 (50%) eyes. Average CMT and CT while under SO tamponade were 400.16 and 206.33 µm, respectively. Post SO removal, IRC were noted in 2/6 (33%) eyes, SRF in 1/6 (16.67%) eyes, EZD in 3/6 (50%) eyes, ELMD in 3/6 (50%) eyes, and HO in 2/6 (33.33%) eyes. Average CMT and CT post SO removal were 372.33 and 216.5 µm, respectively.

Conclusions: Structural abnormalities of retinal architecture on SD-OCT in silicone oil filled eyes appear to improve in some eyes following oil removal.
