title: [Role of Doppler in the diagnosis of ophthalmic complications of Horton's disease].
abstract: A study of the eyeball was carried out using a double frequency Doppler transducer in 31 patients suffering from histologically confirmed temporal arteritis. These patients were divided into 3 groups depending on the results of the ophthalmological examination: group A: 20 patients; normal ophthalmological exam, group B: 5 patients; non specific ocular anomalies, group C: 6 patients; ocular lesions specific to temporal arteritis (ischemic optic neuropathy with amaurosis, dysoric nodules). Doppler examination demonstrated normal curves in the patients in groups A and B. The mean amplitude of systolic peaks was 7.9 mm in group A and 10.3 mm in group B (P = NS). These data did not differ from those of a control population of 22 subjects not suffering from temporal arteritis. On the other hand, group C demonstrated important anomalies on Doppler examination: lack of ophthalmic signal in one case; marked dampening of curves in 4 cases; zones of turbulence in one patient. The mean amplitude of systolic peaks was drastically decreased (1.8 mm). After steroid treatment, a significant increase in blood velocity was seen leading to a normalization of tracings in the majority of cases, including the patients in group C. Doppler examination would appear capable of reliably assessing the risk of ophthalmic complications of temporal arteritis when blood flow anomalies exist. On the other hand, patients with normal Doppler curves may be considered to be at little risk. Subjects at high risk should be urgently treated with high doses of steroids and can be regularly monitored by repeated Doppler examination.
