POS0810 FREQUENCY OF VISUAL MANIFESTATIONS IN GIANT CELL ARTERITIS IN NORFOLK

Background The ophthalmic features of giant cell arteritis (GCA) involve a spectrum severity from transient symptoms to bilateral visual loss anterior ischaemic optic neuropathy or less commonly central retinal cilioretinal artery occlusion. Reported ocular involvement varies between 10-70%. 1,2 . At the Norfolk and Norwich University Hospital an interdisciplinary fast track service is provided for potential GCA patients. This report aims provides complete picture frequency nature in GCA. Objectives 350 records consecutive patients diagnosed objectively with based on biopsy imaging were reviewed. In our centre, hospital pathway mandates all suspected cases have formal ophthalmology assessment including acuity, pupil exam full-dilated fundus assessment. Systemic Ophthalmic signs recorded.
