Corneal Biomechanical Properties in Patients With Arcus Senilis
Cornea, 2016To compare the corneal biomechanical properties and intraocular pressure (IOP) levels in patients with and without arcus senilis (AS).Ocular response analyzer measurements were performed on the right eyes of 37 patients with AS (group 1) and 37 control eyes (group 2).

Lipid-protein constituents of human corneal arcus
Atherosclerosis, 1981Extracts of fresh senile human peripheral cornea with varying degrees of arcus were prepared by soaking minced tissue in buffered saline/EDTA. Apolipoprotein B was, at most, an occasional feature of these extracts; interactions involving glycosaminoglycans were not evident; and the lipid composition, particularly of the cholesterol ester fraction, was ...

Corneal Arcus as First Sign of Familial Hypercholesterolemia
The Journal of Pediatrics, 2014Figure 2. Corneal arcus is separated from the limbus by a thin ring of clear cornea (named “lucid interval of Vogt”). A 4-year-old boy was referred for investigation after his parents noticed the presence of a grayish ring parallel to the limbus of both eyes. His past medical history was unremarkable.

Corneal Arcus Segmentation Method in Eyes Opened Naturally
Lecture Notes in Computer Science, 2016Detection of the corneal arcus by image analysis has important significance for the disintegration of the abnormal lipid metabolism. The traditional method is accompanied with the problem of robustness when the image is collected by non-invasive way. In this paper, an improved corneal arcus segmentation method is proposed. Firstly, locate the candidate

To the Editor. —I would like to comment on the article by Naumann and Kuchle1in the August 1989 issue of theArchivesregarding unilateral arcus lipoides corneae with traumatic cyclodialysis in two patients. I would make note that unilateral arcus senilis was also reported by Smith and Susac2inJAMAin 19732and unilateral corneal arcus without carotid ...

Racial Differences in the Prevalence of Corneal Arcus
Archives of Environmental Health: An International Journal, 1970A random sample of 300 employees from the working population of a sugar estate in Trinidad was examined to determine the racial prevalence of corneal arcus and its relationship to blood pressure and serum cholesterol. The higher frequency of corneal arcus in Indians and Negroes, as compared with Europeans, is shown and is especially marked in the ...

Corneal arcus presents many puzzling features. The correlation between its incidence and serum lipid levels is poor and, using immunoelectrophoresis, we have only been able to identify low-density lipoprotein inconsistently in corneae containing this deposition.

Corneal Arcus and Cardiovascular Risk Factors in Asians in Singapore
International Journal of Epidemiology, 1992This study was a cross-sectional random survey of the whole of Singapore, based on 2143 subjects (aged 18-69 years, response rate 60.3%). The presence of corneal arcus was determined by a doctor using the naked eye in good light. Cardiovascular risk factors were measured by standardized techniques. The prevalence rates overall of corneal arcus were: 18-

Corneal arcus and hyperlipidemia: findings from an older population
American Journal of Ophthalmology, 2004To quantify the association between arcus and hyperlipidemia in an older population.Cross-sectional population-based study.Arcus and serum lipids were measured in the Blue Mountains Eye Study (n = 3,654, aged >49 years). Arcus was graded as absent, partial ( or =180 degrees).
