Me thods: A restrospective analysis of 166 consecutive patients 50 years or older w ith diagnosis of exudative age-related macular degeneration (AMD) was conducted . Color fundus photographs were taken and fluorescein and indocyanine green (ICG ) angiography were performed in all patients. Results: Of the 166 patients, 37 p atients (22.3%) initially suspected of having exudative AMD were ultimately dia gnosed as having PCV. Twenty-seven men (73.0%) were affected, 32 patients (86. 5%) were unilaterally involved. Of 42 eyes with PCV, 27 eyes (64.3%) demonstra ted polypoidal dilations with branching vascular network, and the other 15 eyes (35.7%) showed scattered polypoidal dilations without identifiable continuous b ranching vascular network on ICG angiography. The predominant location for these lesions was at the macular region in 26 eyes (61.9%), the temporal vascular ar cade in 9 eyes (21.4%), the peripapillary area in 6 eyes (14.3%), and the midp eriphery in 1 eye (2.4%). Conclusions: PCV is a common disease in elderly Chine se patients. In our study group PCV mainly affected men and was mostly unilatera l. Most of the lesions were located in the macular region and temporal vascular arcade.展开更多
