High Blood Pressure and Eye Floatters

high blood pressure eye floaters

High blood pressure has long been linked to eye conditions like floaters (tiny specks that move across vision). By keeping blood pressure within reasonable levels, we can protect our eyes from damage and ultimately avoid blindness.

Long periods of high blood pressure can result in retinal vein occlusion (CRVO). CRVO occurs when your retina develops new fragile, leaky vessels which bleed into the clear gel inside your eye (vitreous humour) forming dark strings across your vision that create clumps or dark strings that move across it.


High blood pressure (hypertension) poses serious threats to overall health and many different organs. High blood pressure also increases the risk of eye problems, specifically retinal issues. Retinal tissue is located at the back of each eye and critical for vision; when blood pressure becomes too high, its impact can cause blood vessels to constrict, leading to vision issues like floaters and blurriness; untreated hypertension can even result in irreversible vision loss.

Floaters are small clumps of gel or cells that appear to float in the eye, appearing as black or gray specks, strings, or cobwebs that move around your field of vision. You may notice them more readily against a plain or dark background. Usually harmless and unimportant to note for most individuals but more prominent among older individuals; occasionally however they could indicate retinal detachment which should be addressed immediately by seeking medical advice.

If you notice a sudden increase in floaters and flashes of light, it could be a telltale sign that it’s time to seek medical assistance immediately. These symptoms could indicate retinal tears or hemorrhages related to diabetes or high blood pressure (hypertension), necessitating immediate medical intervention to avoid permanent vision loss.

If you are experiencing floaters, try not to stare directly at them but instead move your eyes up and down several times to shift any fluid that may be causing them. This should shift out of sight the floaters until they fade from sight altogether. If this method fails, try staring at plain background such as pastel walls or skyscapes in order to reduce their visibility; or blink several times which should also help shift fluid. If these symptoms continue, please seek medical assistance immediately from either an ophthalmologist or primary care physician.


As people age, many experience floaters on the retina which is seen as normal. With age comes shrinkage of the vitreous humour which causes it to clump together resulting in shadows being cast onto the retina which patients notice as floaters. These floaters, sometimes appearing like a web or small black dots in the centre of vision, may be quite irritating for some individuals. If they are not particularly large however, most patients can ignore them until they clear spontaneously within weeks or months. Sometimes however, floaters may be caused by bleeding into the vitreous (vitreous haemorrhage), in which case an urgent appointment with a physician should be made as soon as possible regardless of its cause being determined.

In some instances, floaters may be caused by blood leaking from retinal veins; this may be the result of an artery occlusion known as Branch Retinal Vein Occlussion (BRVO) occurring at a crossing of retinal arteries and veins that has resulted in central vision loss. It is thought that these BRVO occlusions may have their source in atherosclerosis-hardening of arteries within this area that weakens vessels enough to rupture them causing ruptured vessels which causes rupture of vessels within this crossing area causing rupture to occur within their own length of their length causing rupture within them selves resulting in central vision loss causing central vision loss and central vision loss as a whole.

High blood pressure increases your risk for eye diseases and conditions, so it is crucial that it remains under control. Receiving regular eye examinations can also help identify any potential issues and treat them early – decreasing your chances of serious damage or vision loss.


Unexpected floaters should be considered a warning signal and you should seek professional medical help, particularly if flashes of light or veil-like images appear. These symptoms could be signs of hypertensive retinopathy – which occurs when high blood pressure damages retinal blood vessels, leading to narrowing, restricted flow and bleeding – leading to symptoms that include sudden appearance of floaters as well as irreparable eye damage or loss of vision – the severity of which depends on how effectively blood pressure control is managed.

Floaters are small specks, lines, dots, cobwebs or strings that appear and disappear within your line of vision. Most notable when viewing plain white or blue backgrounds like walls or skies. Although floaters appear in front of your eyes at times, they actually float inside the clear jelly-like fluid (vitreous) which fills your eyeball; when your head moves they go out of view; these shadow-casting floaters become visible through casting shadows onto retina.

Over time, blood vessels in the retina may leak fluid into the vitreous. This condition is more prevalent among people who have high blood pressure, have had eye surgery or laser treatment for any condition, diabetes and have high cholesterol. Most bleeds resolve within weeks or months on their own but in rare cases it can worsen and even block vision completely.

Ophthalmologists can diagnose this problem through conducting a dilated eye exam, which allows her to access your back eye and blood vessel interior. She may also perform an ultrasound of your retina; such tests will reveal whether the cause of your floaters lies with retinal tears, vitreous hemorrhages or other problems in the back of the eye.

An ophthalmologist may help treat these problems by injecting special medication directly into the eye that dissolves gel deposits. She may also use laser therapy or blood vessel bleeding prevention therapy, and prescribe medications that lower your blood pressure.


High blood pressure has long been known to be the silent killer. Additionally, its damaging effect on eyesight is well documented. High blood pressure causes delicate blood vessels in the retina to narrow or even burst altogether, which may result in various eye conditions like floaters or flashes of light in vision. Managing blood pressure through diet, exercise, and medication can help to avoid these conditions altogether and preserve eye sight.

Floaters are small clumps of gel-like material in the vitreous, which is the clear jelly-like substance behind the lens of your eye. They appear as dots, circles, lines or cobwebs and may move about within your field of vision, creating shadows on the retina – the sensitive layer located at the back of your eye that responds to light.

As we age, our vitreous shrinks, it can pull on the retina and tear or rip it, leading to permanent vision loss. When this occurs, detaching from its attachment points and detaching can result in permanent vision loss.

Blowing out of the vitreous can also produce flashes in one’s vision, often due to fragile new blood vessels on the retina’s surface leaking fluid into it, clouding normally clear gel-like fluid and leaving shadows or floaters. Reabsorbing of that fluid could take days, months or even years depending on your vitreous.

Surgery to eradicate these floaters usually takes one or two hours in an operating room under local anesthetic.

If you notice sudden, significant increases in floaters accompanied by flashes of light, it’s wise to seek medical advice immediately. Such symptoms could indicate more serious eye health conditions like retinal detachments that should be addressed immediately.

Avoiding triggers that lead to eye floaters is the best way to combat eye floaters, including smoking, drinking alcohol and not wearing protective lenses for specific activities. Furthermore, regular eye exams and blood pressure monitoring should be undertaken in order to keep eye floaters at bay.
