High resolution B mode echography and colour Doppler (CDFI) of the macula.
Based on experience from 30 patients the usefulness of high resolution B-scan echography and colour Doppler flow imaging for evaluating lesions of the macula is discussed. With B-scan there is a high detectability of even very flat lesions (less than 1 mm) but fluorescein angiography still gives more detail regarding specific diagnosis. In lesions thicker than 2 mm the Doppler imaging technique adds valuable information about vascularity, to make the assessment of differential diagnosis more exact. The results are considered preliminary; obviously focused ultrasound transducers of high frequency (20 mHz and above) will increase the possibilities of the method.
