Progressive Localized Retinal Nerve Fiber Layer Defect Following Cotton Wool Spots and a Dot Hemorrhage

Abstract

We report two cases of progressive localized retinal nerve fiber layer (RNFL) defect following cotton wool spots and a dot hemorrhage, 63-year-old woman with RNFL defect in inferior temporal retina of the right eye and 43-year-old man with RNFL defect in superior temporal retina of the right eye. Case 1 showed a dot hemorrhage adjacent to RNFL defect in the right eye and a new slit-like localized RNFL defect in the left eye 5 months later. The visual field in the left eye demonstrated corresponding field defect 9 months later. Case 2 showed a slit-like RNFL defect starting from cotton wool spots in the right eye and corresponding visual field defect. Cotton wool spots and dot hemorrhages represented ischemic damages at the nerve fiber layer. Two noticeable cases showed the progression of RNFL defect caused by repetitive localized microvascular ischemic events, resulting in visual field loss.
