Abstract

Giant cell arteritis (GCA) is the most important ­medical emergency in ophthalmology, as was rightly stressed by Kearns [1] when he stated that GCA “ranks as the prime medical emergency in ophthalmology, there being no other disease in which the prevention of blindness depends so much on prompt recognition and early treatment.” A study [2] further emphasized that fact, when it found that a high proportion of patients with permanent visual loss have a delayed diagnosis and treatment; in that study 35% had systemic symptoms for an average of 10.8 months before visual loss and 65% had premonitory visual symptoms for an average of 8.5 days.
