Abstract
PURPOSE
To investigate the prevalence of vitreopapillary traction (VPT) and its effect on peripapillary structure and visual function in eyes with idiopathic epiretinal membrane (ERM).
DESIGN
Observational, comparative study.
PARTICIPANTS
Patients with idiopathic ERM (n = 116 eyes) and controls with similar age (n = 62 eyes).
METHODS
Spectral domain optical coherence tomography (SD-OCT) axial optic disc scans were evaluated to identify VPT in eyes with idiopathic ERM. Based on VPT presence/absence, eyes were categorized as ERM with VPT (ERM+VPT, n = 52 eyes) or ERM without VPT (ERM-VPT, n = 64 eyes). Optic nerve head (ONH) parameters, average and sectoral retinal nerve fiber layer (RNFL) thickness, and central macular thickness (CMT) were compared between groups. Best-corrected visual acuity (BCVA) and visual field (VF) (automated Humphrey central 30-2 perimetry) mean deviation (MD) and pattern standard deviation (PSD) were compared between groups.
MAIN OUTCOME MEASURES
The ONH parameters, peripapillary RNFL thickness, BCVA, VF MD, and PSD.
RESULTS
Fifty-two of 116 eyes (44.8%) with idiopathic ERM had VPT. The ERM+VPT group had larger rim area, smaller average and vertical cup-to-disc ratios, and smaller cup volume than ERM-VPT and normal groups (all P < 0.001). Eyes with VPT had greater CMT than eyes without VPT (421.87±97.31 μm vs. 377.08±75.1 μm; P = 0.006). Average and temporal RNFL thickness was higher in ERM+VPT (98.64±9.33 μm and 93.90±23.42 μm) than in normal eyes (94.02±8.45 μm and 66.42±12.71 μm). No significant difference in BCVA was found between ERM-VPT and ERM+VPT eyes, but MD was lower in ERM+VPT than in ERM-VPT (-3.91±3.68 dB vs. -2.18±2.42 dB; P = 0.005). Additionally, PSD was greater in ERM+VPT. Multivariate logistic regression analysis revealed that age (odds ratio [OR], 1.190; P = 0.014) and increased CMT (OR, 1.013; P = 0.005) were associated with vision loss, whereas VPT presence was associated with VF defects (OR, 6.290; P = 0.024).
CONCLUSIONS
Vitreopapillary traction was observed in >40% of eyes with idiopathic ERM, as confirmed by SD-OCT imaging. Vitreopapillary traction with idiopathic ERM was associated with altered optic disc architecture, increased average and temporal RNFL thickness, and VF defects.
