Diagnosis and Grading Of Papilledema Using Optical Coherence Tomography Compared To Clinical Staging By Frise´n Scale
Objectives To compare and contrast 2 methods of quantitating papilledema, namely, optical coherence tomography (OCT) and Modified Frisén Scale (MFS). Methods Digital optic disc photographs and OCT fast retinal nerve fiber layer (RNFL) thickness, fast RNFL map, total retinal thickness, and fast disc images were obtained in 36 patients with papilledema. Digital optic disc photographs were randomized and graded by 4 masked expert reviewers using the MFS. We performed Spearman rank correlations of OCT RNFL thickness, OCT total retinal thickness, and MFS grade from photographs. Results OCT RNFL thickness and MFS grade from photographs correlated well ( R = 0.85 ...
