Because of the frequent presence of corneal arcus senilis in patients affected by Dupuytren's disease in order to evaluate this association, the authors conducted a biomicroscopic examination of the cornea in 336 patients treated surgically for Dupuytren's disease, at the Hand Surgery Unit of the University of Modena from November 1985 to December 1989. They observed corneal arcus senilis in 259 patients, i.e. in 77.1% of patients with Dupuytren's disease. Due to the statistically significant correlation between arcus senilis and hyperlipidemia as reported by Tschetter (1980) and Felder (1981), the Authors collected a blood sample from all 336 patients to evaluate serum cholesterol and tryglicerides. This study revealed a dyslipidemia in 54.8% of patients with Dupuytren's disease and in 60.2% of patients suffering from both Dupuytren's disease and arcus senilis. Because of the high frequency of dislipidemia in patients with Dupuytren's disease and arcus senilis, which are apparently two well-distinguished disease, the authors suggest that a lipid disorder may be a common aetiopathogenic factor. In particular, in favour of the possible role of hyperlipidemia in Dupuytren's disease, Electron Microscope Studies revealed lipid inclusions within fibroblasts and in the extracellular connective tissue of all pathologic palmar aponeurosis from 11 patients with Dupuytren's disease: these lipid inclusions were never seen in the normal aponeurosis taken from 5 control patients treated for traumatic palmar injuries.

Disorders of lipid metabolism, either hyperlipidemia or hypolipidemia, are associated with the formation of corneal opacities. Corneal arcus, the most commonly encountered peripheral corneal opacity, is frequently associated with abnormal serum lipid levels, but may occur without any predisposing factors. Reports also have linked corneal arcus with alcoholism, diabetes mellitus and atherosclerotic heart disease. Unilateral arcus is a rare entity that is associated with carotid artery disease or ocular hypotony. Diffuse corneal opacities associated with hypolipidemic disorders such as LCAT deficiency, fish eye disease and Tangier disease, may be the initial manifestation of these disorders and puts the ophthalmologist in a position to make an early diagnosis. Corneal arcus, along with a central corneal opacity, is seen in Schnyder's crystalline stromal distrophy. The association of the disorder with a dyslipidemia remains controversial. A review of lipid metabolism, corneal arcus and several disorders of lipid metabolism that affect the cornea are presented.

The relationship between corneal arcus (arcus senilis) and mortality from coronary heart disease (CHD) and cardiovascular disease (CVD) is examined in a prospective study of White men (n = 3,930) and women non-hormone users (n = 2,139), ages 30-69, followed for an average of 8.4 years as part of the Lipid Research Clinics Mortality Follow-up Study. After excluding those with clinically manifest CHD at baseline, corneal arcus was strongly associated with CHD and CVD mortality only in hyperlipidemic men ages 30-49 years, for whom the relative risk for CHD and CVD death was 3.7 and 4.0, respectively, after adjusting for age, total cholesterol, HDL cholesterol, and smoking status using a Cox proportional hazards model. Among 30-49 year old males, corneal arcus appears to be a prognostic factor for CHD, independent of its association with hyperlipidemia in this age-group, of about the same magnitude as other common risk factors, underscoring the usefulness of corneal arcus as a prognostic factor to the practicing clinician.

Corneal arcus and serum lipids were studied in 121 men, aged 30 to 80, with atherosclerotic coronary heart disease (CHD), and in healthy controls. In both groups the incidence of arcus increased from 55% in the fifth decade to 90% in the eighth. Under 40, arcus was a significant differentiating sign, being present in 11 of the 25 coronary patients and in none of the controls. In both groups, to age 60, the incidence of arcus correlated with serum cholesterol and phospholipid but not with standard Sf 0-400 lipoprotein fractions. In the CHD group there was significant elevation of the serum lipids. Since arcus is itself a fatty infiltration of the eye, these findings support the importance of serum lipids in atherogenesis. Clinically, corneal arcus in a male under 40 may be a clue to hyperlipidemia and a propensity to CHD.
