„ARCUS SENILIS AND ITS SIGNIFICANCE“
Arcus senilis appears as a white ,gray,or blue ring or arcaround the cornea of the eye.The condition is usually in older adults but can affect people of all ages,even appearing at birth.It is also known as arcus senilis corneae.In people under 40 years old,it can also be known as arcus juvenilis.Those affected by this eye condition will notice a half circle,full circle,or arc around the cornea of their eye.The cornea is the clear,dome-like front part of the eye.The arc or circle is usually white,gray,or blue in color.It forms in front of the iris,which is the colored part of the eye.Although the appearance of arcus senilis can be alarming ,it is usually not considered to be a danger to a persons health or a sign that vision is deteriorating.However,visiting a doctor will ensure that there are no hidden causes that could lead to further health complications if the eye change is left untreated.
The vast majority of people affected by arcus senilis are older adults,as the main cause of the condition is aging.In fact nearly 100% of people over 80 years old will be affected.Around 60% of people over 60 years of age will also have this condition.Arcus senilis occurs due to fat deposits,often referred to as lipids,forming in the outer part of the cornea.Fats in the blood come from fatty foods in a persons diet and are also produced by the liver.Cholesterol is one type of fat that appears in the blood.However,the occurrence of arcus senilis does not necessarily mean that someone has high cholesterol.The blood vessels in the eyes widen with age.As someone ages ,their blood vessels allow more cholesterol and other fats to build up in the eye.If arcus senilis appears in people under the age o 40 years old,doctors will carry out a test to check for high cholesterol.If a person is found to have high cholesterol,this may be due to lifestyle factors or an inherited condition known as central crystalline dystrophy.This condition causes cholesterol crystals to build up in the central cornea along with arcus senilis in the peripheral cornea.Although arcus senilis is a common condition,it is more likely to occur in men.It is also possible for infants to be born with arcus senilis,but this is extremely rare.
For most people ,arcus senilis is no cause for concern,and it will appear eventually in almost everyone who reaches old age.
SYMPTOMS
A person with arcus senilis may notice:
-a white ,gray,or blue circle or arc around the cornea of the eye.
-the circle or arc will have a sharp outer border but a blurred inner border.
-if someone has an arc,the lines could grow to form a complete circle in front of the iris
If both arcus senilis and atherosclerosis are suspected ,people are usually referred to their primary care doctor,an internist,or a cardiologist.A blood test will determine whether someone has high cholesterol.If they do,they may be prescribed medicine or advised on a suitable diet and exercise program to lower the cholesterol in their blood.
The link between arcus senilis and high cholesterol in older people is a subject of debate among medical professionals.Some experts believe that there is a link between the condition and high cholesterol,which can lead to cardiovascular problems.Others argue it is a normal sign og aging and that there is no link between the condition and higher levels of cholesterol.If arcus senilis appears in a person under 40 years old,there is more likely to be cause for concern,as it may indicate that they have high cholesterol levels.High cholesterol could be due to diet,lifestyle,or genetic conditions,such as familial hyperlipidemia.It is a hereditary condition where extremely high levels of cholesterol or triglycerides are found in a persons blood,putting them at increased risk of heart disease.If arcus senilis is a sign of high cholesterol,a doctor may recommend a diet that is low in saturated fats and high in fruit ,vegetables and fiber.Increased exercise and quitting smoking can also help.
