Arcus senilis is a deposition of lipid at the corneal periphery. It is dependent on vascularity for formation and is not a degenerative change. The prevalence of arcus increases with age, and it appears more in blacks and males. It appears to be related to cardiovascular disease but has not been shown to be a reliable predictor of the disease. We studied the incidence of arcus width with age and found no definite correlation.
角膜老年环是脂质在角膜周边的沉积。其形成依赖于血管，并非退行性改变。角膜老年环的患病率随年龄增长而增加，在黑人和男性中更为常见。它似乎与心血管疾病有关，但尚未被证明是该疾病的可靠预测指标。我们研究了角膜老年环宽度随年龄的发生率，未发现明确的相关性。
