Abstract
Objective To analyse the indocyanine green angiographic findings in contralateral eyes of patients with unilateral exudative age related macular degeneration(AMD). Methods Fundus photograph,fundus fluorescein angiography(FFA) and indocyanine green angiography(ICGA) were performed in a series of 70 patients with unilateral AMD and drusens and pigmentary changes in the macular region in contralateral eyes.The findings of fluoroangiograms were observed and analysed. Results ICGA revealed the characteristics of the contralateral eyes as follows:(1)Drusen could be hypofluorescent,hyperfluorescent or normal fluorescent;(2)14 eyes revealed plaque like late hyperfluorescent;(3)13 eyes revealed choroidal filling defect;(4)18 eyes revealed pindot like clusters of late hyperfluorescence. Conclusion ICGA is useful in evaluating the lesions and circulation disturbance of the contralateral eye,and may help to find the risk factors of developing future exudative changes.
