[Role of Doppler in the diagnosis of ophthalmic complications of XXXX ].

A study of the eyeball was carried out using a double frequency Doppler transducer in 31 @entity1 suffering from histologically confirmed @entity226 . These @entity1 were divided into 3 groups depending on the results of the ophthalmological examination: group A: 20 @entity1 ; normal ophthalmological exam, group B: 5 @entity1 ; non specific @entity735 , group C: 6 @entity1 ; ocular lesions specific to @entity226 ( @entity1781 with @entity1939 , dysoric nodules). Doppler examination demonstrated normal curves in the @entity1 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 @entity226 . 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 @entity1 . 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 @entity1 in group C. Doppler examination would appear capable of reliably assessing the risk of ophthalmic complications of @entity226 when @entity450 exist. On the other hand, @entity1 with normal Doppler curves may be considered to be at little risk. Subjects at high risk should be urgently treated with high doses of @entity230 and can be regularly monitored by repeated Doppler examination.
