Objective To investigate the possible relationship between choroidal neovascularization (CNV) and macular choroidal watershed zones (CWZ) in patients with age-related macular degeneration (AMD). Methods Fifty-seven selected indocyanine green video angiograms (ICGA) of 57 patients (57 eyes) with AMD were evaluated, and 35 ones of the healthy fellow eyes of 35 patients with unilateral non-AMD fundus diseases were selected as age-matched control. The video angiograms were evaluated for investigating the relationship between CNV and macular CWZ. Results In 57 eyes with AMD, 35 (61.4%) had macular CWZ, while in 35 control patients only 3 (8.57% ) had. The difference was significant (P lt;0.05). In 43 eyes with exudative AMD and CNV, 32 (74.4%) had macular CWZ, including 29 eyes (90.6%) with CNV caused by macular CWZ. Conclusion Macular CWZ could be a predilection site of CNV in exudative AMD. (Chin J Ocul Fundus Dis，2003，19：76-78)
