Low cholesterol increases your risk for eye disease. Maintaining normal blood pressure levels, eating healthily and engaging in physical activities are proven strategies to lower these odds.

Ophthalmologists should refer patients who exhibit abnormal cholesterol levels to an eye doctor for evaluation. Ocular symptoms that indicate elevated cholesterol include xanthelasma around eyelids and arcus senilis (familial HDL cholesterol deficiency). Furthermore, white retinal intravascular lesions associated with hypertriglyceridemia have also been noted in eyes.

Xanthelasma

Xanthelasma (zan-thee-laz-ma) is a condition associated with high cholesterol levels that results in fatty deposits under and around the eyes, usually yellow plaques near the inner corners of upper and lower eyelids, that have soft velvety textures, often coalesce and grow larger over time. Although harmless, they can be unsightly. In extreme cases, large deposits could even interfere with proper lid functioning (ptosis).

Xanthelasma typically does not cause symptoms or discomfort, but should still be investigated. In such a scenario, dietary recommendations and cholesterol-lowering drugs can help decrease liver production of cholesterol while simultaneously decreasing triglyceride levels and increasing HDL cholesterol to help protect against atherosclerosis and heart attacks.

Note that Xanthelasma can recur, and thus should be treated promptly. Furthermore, those living with xanthelasma are at a greater risk for atherosclerosis in their brain arteries and coronary artery due to it acting as an early indicator of atherosclerosis in blood vessels of both eyes and body.

Xanthelasma can be an indicator of familial hypercholesterolemia, an inherited disorder in which there is excess cholesterol accumulation within cells of the body, which necessitates medical intervention. Atypical hyperlipidemia should also be taken seriously.

Even though xanthelasma is typically cosmetic in nature, patients may choose to have it surgically removed for cosmetic reasons. This can be accomplished under local anesthetic. Other treatments include topical TCA or chemical peels as alternatives; however recurrence remains likely and these methods should be reviewed with regular check-ups. Furthermore, smokers who are more at risk should be regularly screened for atherosclerosis and cardiovascular issues due to an untreated xanthelasma condition can lead to heart attack or stroke complications; especially among smokers at increased risk.

Corneal Arcus

An outer white or gray arc or ring around the outer part of your cornea – the clear domelike covering over your front eye–is another sign of high cholesterol eyes, caused by fat (lipid) deposits deep within corneal margin. While typically only seen among older adults, familial hypercholesterolemia cases may present with it as well resulting in what’s called arcus senilis – it does not indicate high blood cholesterol levels or increased risk for cardiovascular disease, nor require treatment.

The cornea’s role is to capture light and transmit it through to the retina, where light signals are transformed into nerve impulses that your brain interprets as visual information. But when fat accumulates on retinal blood vessels and blocks their flow, retinal vein occlusion occurs, leading to gradual vision loss or in extreme cases leading to blindness – this is why keeping cholesterol within normal range is so vitally important.

Cholesterol can be found throughout your body in the form of waxy deposits that build up over time, narrowing and hardening arteries, as well as building up in soft tissues like your skin or even in the linings of your eyes, leading to cataracts or other vision-related problems. Its presence is especially detrimental in women as this substance increases estrogen production while simultaneously contributing to hardening. If left unchecked, cholesterol can form plaques which block arterial flow causing narrowing. Also forming deposits on arterial walls causes narrowing. Buildup occurs both inside soft tissues as well as within eye linings which causes cataracts as well as vision problems – see #10.

High cholesterol may contribute to glaucoma, a condition whereby fluid from your eye’s anterior chamber increases and presses on your optic nerve, leading to pain or blindness in one or both eyes. To help avoid glaucoma altogether, reduce both cholesterol and blood pressure levels as much as possible.

Recent research compared arcus senilis presence with central corneal thickness (CCT) and intraocular pressure (IOP). It included 3280 Malay participants who underwent standardized interviews and systemic and ocular examinations – including slit lamp examination. Arcus senilis was associated with both lower CCT and higher IOP regardless of age or gender – suggesting it is a reliable indicator of glaucoma risk, and may serve as a marker for other cardiovascular risk factors like inflammation.

Carotid Artery Plaques

The carotid arteries, situated on either side of your neck, supply oxygen-rich blood to your brain and other parts of your body. But over time they may narrow due to atherosclerosis, potentially leading to stroke or heart attack. Over time clumps of cholesterol, calcium and fibrous tissue accumulate at microscopic injury sites within an artery before hardening into plaque that restricts its blood supply – atherosclerosis can impact any artery including those supplying blood directly to your eyes!

Smoking, excessive alcohol use, high cholesterol, elevated blood pressure and diabetes all pose risk factors that contribute to the formation of fatty streaks on arterial walls, leading to plaque build-up over time. Plaque rupture can occur or blood clots may form which partially or completely block flow in an artery and result in stroke; dislodged material from plaque may travel through bloodstream and block smaller arteries supplying brain-related regions, potentially leading to transient ischaemic attack (TIA) or mini stroke.

Your doctor will listen to your carotid arteries with a stethoscope, listening for sounds which indicate decreased or altered blood flow due to plaque build-up. He or she may ask about family history of stroke, any previous transient ischaemic attacks (TIAs) you’ve had and any symptoms you are experiencing.

If your doctor diagnoses atherosclerotic stenosis in either carotid artery, treatment will involve controlling cardiovascular risk factors and taking medications to lower cholesterol levels and prevent blood clot formation. He or she will use Doppler ultrasound to monitor your vascular health; and, if necessary, surgery (carotid endarterectomy), to remove affected area. General anesthesia will be administered before incision is made near site of blocked artery before the surgeon removes and repairs affected wall before closing incision and closing incision after removal and removal of affected wall after which repair it all before closing the incision and closing incision closed again by surgeon.

Glaucoma

Glaucoma is an eye condition in which fluid pressure in the eye becomes too high, damaging the optic nerve and leading to vision loss. It is the second leading cause of blindness worldwide. Glaucoma often goes undetected for years until severe blurriness arises as symptoms. Glaucoma is progressive disease which continues to worsen over time; thus regular eye exams and screening for it are key.

Healthy eyes produce and transport clear fluid known as aqueous around freely through an internal drainage system, but if that system becomes blocked or obstructed, pressure rises, potentially damaging optic nerves and leading to vision loss. Therefore, treatment aimed at lowering eye pressure in order to preserve vision.

There are various forms of glaucoma. Open-angle glaucoma (POAG) is the most prevalent, where drainage channels fail and fluid accumulates within the eye leading to elevated pressure and damage to optic nerve. Other types include angle-closure glaucoma (CAG) and normal tension glaucoma, in which patients experience similar damage as POAG but with normal intraocular pressure readings.

Studies have revealed that those with higher cholesterol levels have an increased risk of glaucoma; however, taking statins, an anticholesterol medication which effectively lowers cholesterol, significantly decreases this risk.

Glaucoma affects everyone, yet no one knows who will develop it or when. There is no reliable way of predicting its onset; however, certain risk factors increase the odds such as family history, ethnicity, diabetes, smoking or previous eye injury/surgery. Individuals with family histories of glaucoma should receive regular eye examinations and monitor for any changes, while seeing an ophthalmologist for hypertension, high blood glucose levels or vision problems is advised as soon as possible.
