Temporal arteritis: a spectrum of ophthalmic complications.
Seven patients of temporal arteritis with eye involvement have been presented. These cases represent a spectrum of disease from intermittent diplopia with minimal 6th nerve weakness through mild retinal ischemia with recovery to permanent bilateral blindness. Temporal arteritis should be suspected when any form of ocular ischemia is suspected by history or found on examination of an elderly person. An early diagnosis may protect the vision in both eyes if vision is normal at the time of diagnosis. If vision in one eye is decreased because of ischemia, the vision in the other eye can usually be retained if proper therapy is instituted. Furthermore, adequate therapy may even result in improvement in vision in the involved eye. Patients with biopsy proven temporal arteritis should be continued on steroid therapy until the active disease is quiescent. Inactivity should be determined by carefully monitoring the ESR while steroids are being tapered. If the ESR rises, it is indicative of continued inflammation and if steroids are not continued, the eyes remain at risk as seen in Case 5. If the ESR remains elevated for a year or more despite continuation of high steroid levels, consideration should be given to repeating the temporal artery biopsy. Temporal arteritis should be considered in the differential diagnosis of any multisystem disease in older patients. Even central nervous system involvement may occur concomitantly, since the intracranial vessels are not immune from the disease process. Tuberculosis, systemic syphilis and more recently the collagen vascular diseases have been dubbed the "great imitators" and "the protean diseases." We suggest that the same terminology can be applied to temporal arteritis. Temporal arteritis can affect any organ. Moreover, there is a wide spectrum of variation in the degree of involvement of any particular tissue as illustrated by these 7 cases of ocular involvement.
