SUMMARY A description is given of apparatus and technique for carrying out cine photography and video recording of anterior segment fluorescein angiography. We found cine best for singleframe analysis and video tape recording less expensive.Anterior segment angiography was introduced 10 years ago on the fundus camera (Jensen and Lundback, 1968) and on the slit lamp camera 9 years ago (Brun-Jensen, 1969;Mitsui et al., 1969). It was found to provide useful information on conjunctival and corneal lesions, especially in lipid keratopathy (Bron and Easty, 1970). Abnormal vascularity of the iris is particularly well demonstrated in anterior segment ischaemia (Chignell and Easty, 1971;Marsh et al., 1974), in glaucoma (Vannas, 1969), in diabetes (Cobb, 1968;Jensen and Lundback, 1968), and after central retinal vein and artery occlusions (Raitta and Vannas, 1969;Mapstone, 1970;Kottow, 1976;Laatikainen and Blach, 1977).One of the major photographic defects which soon becomes apparent in anterior segment angiography is that the standard machines do not give a fast enough sequence of photographs during the early phase of fluorescein filling. This is important because in diseased states of the anterior segment significant changes in the vascular pattern and permeability occur within the first 5 seconds of fluorescein appearing within the eye. In our experience with the Zeiss photo-slit lamp at best we could obtain 6 consecutive exposures at I second intervals, after which there was a delay of 13 seconds for recycling.We set out therefore to develop a cine technique so that these very early stages of vascular fluorescein filling could be analysed. We decided at the same time that we should also take standard 35
