The refractive error of 186 eyes with choroidal neovascularization (CNV) secondary to age-related macular degeneration (ARMD) was determined. It was found that the risk for the development of this form of ARMD increased with increasing degrees of hyperopia. The 96 patients afflicted with bilateral CNV were significantly older than the unilaterally affected patients (P = 0.027). Abnormal choroidal perfusion was identified in 66.4% of the fluorescein angiograms. These findings support the concept that hyperopic shortening in eyes afflicted with ARMD might cause secondary changes in the choroidal vasculature, predisposing them to choroidal neovascularization.
对186例继发于年龄相关性黄斑变性（ARMD）的脉络膜新生血管（CNV）眼的屈光不正情况进行了测定。结果发现，这种形式的ARMD的发病风险随着远视程度的增加而升高。96例双侧CNV患者的年龄显著高于单侧受累患者（P = 0.027）。在66.4%的荧光素血管造影中发现脉络膜灌注异常。这些发现支持这样一种观点，即患有ARMD的眼睛的远视性缩短可能会导致脉络膜血管系统的继发性改变，使其易发生脉络膜新生血管。
