Abstract

BACKGROUND: Papilledema is the swelling of the optic disc secondary to raised intracranial pressure. IIH is characterised by raised ICT with normal CSF and may cause papilledema. There is sparse information on changes in optic disc perfusion in such patients. We aim to evaluate the peripapillary vessel density(vD) in IIH patients with papilledema using OCT-A. METHODOLOGY: Prospective case control study of 40 eyes (20 patients) with age matched controls assessed by a single trained ophthalmologist. Baseline OCT-A was performed and vessel density calculated for all participants. RESULTS: Group with papilledema were found to have increased vessel density as compared to controls, significantly the inferior, inferonasal and superonasal peripapillary vessel density. CONCLUSION: IIH patients display vascular abnormalities specially in the inferior and nasal region which can be detected by OCT-A.
