Value of fluorescein iridography in diagnosis of tumours of the iridociliary zone.
Fluorescein iridoangiography of 33 eyes with benign tumours and 22 eyes with malignant tumours is discussed. In cases of leiomyoma the tumour vessels have a distinct pattern, and fluorescence of the tumour tissue is mottled and short-lived. Malignant tumours are characterised by distortion of their vessels. Simultaneously the patches of fluorescence appear in the tissue of the tumour and lead to a diffuse confluence. Changes in the architecture of the vessels of the iris near the tumour and absence of fluorescence at the pupil margin indicate growth of the neoplasm.
