TY - JOUR T1 - Tonic pupil with giant cell arteritis. JF - British Journal of Ophthalmology JO - Br J Ophthalmol SP - 135 LP - 138 DO - 10.1136/bjo.68.2.135 VL - 68 IS - 2 AU - J. Currie AU - S. Lessell Y1 - 1984/02/01 UR - http://bjo.bmj.com/content/68/2/135.abstract N2 - A patient with giant cell arteritis and ischaemic optic neuropathy developed bilateral tonic pupils. This pupillary abnormality may result from ischaemia of the ciliary ganglia. Despite the propensity for patients with giant cell arteritis to develop vascular occlusions in the eye and orbit, tonic pupils have rarely been described, and several reasons for this are proposed. The arteries supplying the ciliary ganglia are frequently involved in giant cell arteritis, but their anastomotic pattern may confer protection from ischaemia. Tonic pupils may also be overlooked amidst the more dramatic manifestations of giant cell arteritis. ER -
