Darma S, van den Berg TJTP, Kok PHB, et al. - Among 13 cataract patients (13 right eyes) using measurements before and after cataract surgery, researchers sought to correct peripapillary retinal nerve fibre layer (pRNFL) measurements conducted with spectral domain optical coherence tomography (SD-OCT) for low image quality factor (QF). For this investigation, they used SD-OCT (Topcon 3DOCT-2000) volume scans of the optic disc of cataract individuals (n = 13). Before and after cataract, pRNFL thickness measurements varied significantly. The existence of cataract affects the QF-pRNFL association. It was noted that the lower the image QF, the higher the pRNFL thickness underestimation. They observed a rather curvilinear link between QF and pRNFL. The corrected measurements of the pRNFL thickness in the case of lower image QF because of cataract still varied significantly from the pRNFL thickness measurements following cataract surgery.
