Abstract
- Purpose: To evaluate the retinal nerve fiber layer (RNFL) thickness, the ganglion cell complex (GCC) and vessel density of the radial peripapillary capillary (RPC) plexus of eyes with regressed papilledema in idiopathic intracranial hypertension (IIH) patients using optical coherence tomography angiography (OCT-A) and comparing the results with healthy controls.<br />Materials and Methods: Fifty-one eyes of 31 patients diagnosed with IIH and 52 eyes of 52 healthy subjects were enrolled in this study. All patients underwent a complete ophthalmological examination and a 4.5 × 4.5 mm peripapillary OCT-A scanning. The quantitative results of the peripapillary RNFL and GCC thicknesses and vessel density of the RPC were analyzed.<br />Results: The vessel density in the inferior, superior nasal, and inferior nasal sectors of the patients with IIH significantly exceeded the vessel density of the healthy controls (P = 0.008, P = 0.008, and P = 0.000, respectively). The RNFL and GCC thickness measurements were comparable in both groups.<br />Conclusions: Patients with IIH show vascular abnormalities in the inferior nasal region, which can be detected with OCT-A. As a noninvasive imaging modality, OCT-A could provide a new perspective for understanding the pathophysiology of IIH and could also be useful in the follow-up of these patients.<br /> (Copyright © 2021.
