Relationship between Arcus senilis and high cholesterol

Arcus senilis and the eye findings associated with high cholesterol are distinctly different.

What is Arcus senilis!! It is a gray or white arc visible above and below the outer part of the cornea — the clear, dome-like covering over the front of the eye, also known as arcus cornealis, Eventually, the arc may evolve into a complete ring around the cornea.
Arcus senilis is common in older adults. It's caused by fat (lipid) deposits deep in the edge of the cornea. It isn't necessarily related to high cholesterol, however. Arcus senilis doesn't affect vision, nor does it require treatment.

High cholesterol is more likely associated with a similar gray or white arc visible around the entire cornea (circumferential arcus) in younger adults. Even then, however, eye findings associated with high cholesterol are uncommon — typically affecting only people who have severe cases of high cholesterol and high triglycerides passed down through families (familial hyperlipidemia). Treatment is generally aimed at controlling cholesterol and triglyceride levels.

The average person who has high cholesterol doesn't develop an arc of any type. If you're concerned about eye health and high cholesterol, consult your doctor for an evaluation.

Ectropion



Ectropion is an outward turning of the lower eyelid, most commonly caused by aging, although eyelid burns or skin disease may also be responsible.
Normally, the eyelids help lubricate and cleanse the eye during blinking. The sagging lower eyelid leaves the eye exposed and dry, and as a result, excessive tearing is common with ectropion. If it is not treated, the condition can lead to excessive tearing, crusting of the eyelid, mucous discharge, and irritation of the eye. A serious inflammation could result in damage to the eye. Ectropion can be diagnosed with a routine eye exam. Special tests are usually not necessary.

Symptoms:
The wet, inner, conjunctival surface is exposed and visible. Normally, the upper and lower eyelids close tightly, protecting the eye from damage and preventing tear evaporation. If the edge of one eyelid turns outward, the two eyelids cannot meet properly, and tears are not spread over the eyeball. This may lead to irritation, burning, a gritty, sandy feeling, excess tearing, visible outward turning of the eyelid, and redness of the lid and conjunctiva.


Treatments:
Treatment varies. Make an appointment with your doctor to discuss your condition.But in general
Artificial tears (a lubricant) may relieve dryness and keep the cornea lubricated. Surgery to tighten the muscles that hold the eyelids in place is usually effective. It may be performed as outpatient surgery with local anesthesia.

How to insert contact lenses properly?

Wash, rinse and dry your hands before touching the contacts. A wet finger could cause a soft lens to flatten. Do not use fingernails when handling your lenses. If you are near a sink, close the drain to avoid any mishaps. Always insert your contacts in the same order to eliminate mix-ups. Pour the lens and storage fluid from the case into your palm. Examine your lens for particles, deposits or tears. Place the lens, cup side up, on your forefinger. Be sure the lens is right side out—the lens’ edge will appear almost straight up. If the lens is inside out, the edges will bow out slightly. If the lens is inside out, reverse it before proceeding.


Insertion:


* Hold your upper eyelid or lashes to hinder blinking.
* Pull your bottom eyelid down using your middle finger
* Look up at the ceiling so that the white part of your eye shows and position the lens onto the white part
* Or, you can look forward at the lens and gently situate it in the centre of your eye
* Remove your finger and let the bottom eyelid go before the top
* Look down to position the lens
* Close your eye for a moment.
* Apply one to two eye drops (lens lubricant) if your lenses feel dry or vision blurs.
* Repeat the same steps for inserting the lens for the left (or second) eye.
* Be sure to have your eye doctor demonstrate these steps prior to your first attempt at inserting your lenses

Removal:

Bend over so that your head is parallel to the floor, cup your left hand under your right eye. Place your thumb, index or forefinger of your right hand at the outer corner of your eyelids. Look straight down and open both eyes wide. Pull your finger in an upward and downward direction and remove the lens.

Cleanse, rinse and disinfect your lenses after removal and before wearing them again as contact lens cases can be a source of bacterial growth. Enzyme cleaners and cleaning solutions alone cannot substitute for disinfecting, although there are multipurpose products that can perform many of these functions if used as directed. Never use non-sterile homemade saline, distilled water or tap water for any part of your lens care regimen. Use products recommended by your eye care professional. Not all solutions can be used for all contact lenses. Solutions can become contaminated during use. Do not let the bottle tip touch any surface including your contact lenses.

What is cataract ??


A cataract is opacity or clouding of the lens. It prevents the lens from focussing light onto the retina, hence, causing hazy vision. Aging and other factors may cause the proteins in the lens to degenerate, forming opaque (cloudy) areas. They usually develop slowly over several years and are irreversible.

Black Eyes


Black eyes, even they’re on plummeting toddlers or qualified boxers, are like spotlight calling attention to the damage, perhaps that’s why they’re called “shiners.” The skin and blood vessels nearby the eye are very fragile, so even minor bumps to the eye or temple can cause bleeding.

Gravity supports the blood to pool in the eyelid and area under the eye, creating swollen red, blue, and/or black bruises. Luckily, in most cases, bruises around the eye (medically known as periorbital hematomas) cause more stares than permanent eye damage, with most of the visible signs dispel within one-and-a-half weeks.

How to Cure Black Eye

Most black eyes can be treated at home using the following formula:

1. How to Cure Black Eye with Ice packs - Cool it down - Ice packs or cold squash during the first 24 hours, mainly when used punctually after being injured, could help reduce bleeding and swelling. Raw steaks that have usually been put on black eyes were done so as the meat is cold, not because it has any special healing actions. Ice wrapped in a washcloth or a baggie of frozen veggies are more suitable steak alternate. This is How to Cure Black Eye with Icepacks.

2. How to Cure Black Eye by avoiding a swelled head - Keep your head high (sleep with a few extra pillows, for example) to help frontier swelling and pooling. Over-the-counter (OTC) pain relievers, such as acetaminophen, can also help relieve distress. Avoid aspirin since it reduces the blood’s ability to clot.

3. How to Cure Black Eye by applying moist heat - On the second day following the injury, applying warm wash cloths or squeeze can help augment circulation to the injured tissue. This aids in the re-absorption of any left over blood that has collected at the injury site, endorse healing.
