High blood pressure (or hypertension) can damage arteries throughout the body, including those in the eyes. This damage increases vision issues while simultaneously increasing risk for heart disease, stroke, kidney damage and other serious health conditions.

Eye conditions that restrict retinal blood vessel dilation may lead to thickening and narrowing, restricting blood flow, leading to blurry or double vision, headaches and other symptoms.

Hypertensive Retinopathy

Hypertensive Retinopathy is damage to the retinal blood vessels that transform light into nerve signals that the brain interprets as vision. Uncontrolled high blood pressure exerts excessive force on these blood vessels, narrowing them and restricting blood flow resulting in fluid build-up on the retina, leading to blurred vision, dark spots in visual field and reduced acuity which, left untreated, could eventually result in loss of vision if untreated. Hypertensive Retinopathy can be detected during routine comprehensive eye examination by using an ophthalmoscope projecting light onto fundus area and observe retinal blood vessels through this magnifying device called an Ophthalmoscope to project light onto fundus area for observation of retinal blood vessel networks on fundus area to observe retinal blood vessel structures that transform light into nerve signals for brain interpretation into vision.

Uncontrolled high blood pressure leads to structural changes in retinal blood vessels, due primarily to fat accumulation along their walls (intimal thickening or hyaline degeneration). Fat deposits may compress blood vessel walls, decreasing blood flow to the retina and leading to narrowed vessels and new blood vessel formation at points where arterioles and venules intersect – creating what are known as telangiectasias. These infections cause leakage of blood and fluid into the eye, leading to hemorrhages in both retina and vitreous, leading to impaired vision and distorting vision altogether. Furthermore, breakdown of the blood-retina barrier results in the formation of cotton wool spots or hard exudates which form from these leakages of fluid into retinal capillaries resulting in further eye problems.

Treatment for high blood pressure with vision disturbance typically entails taking medication such as beta blockers, diuretics or calcium channel blockers to lower it gradually and effectively. If necessary, laser surgery may also be used to shrink abnormal blood vessels and ensure optimal control. It is vitally important that follow-ups ensure blood pressure remains under control.

Glaucoma

Glaucoma is an eye condition that leads to vision loss over time, caused when fluid pressure inside of an eye increases and compresses its optic nerve. Progress may happen gradually without symptoms; therefore it is essential to have regular eye exams so this condition can be detected early and treated before any permanent damage occurs.

Eyes contain an aqueous humor fluid which continuously flows in front of them to nourish various parts of their eyeballs and drain through a system called the trabecular meshwork into their normal drainage canals. Sometimes this flow is interrupted or production decreases resulting in high intraocular pressure causing damage to optic nerve fibers which ultimately leads to blindness. Glaucoma symptoms can include blurry vision, vision loss from one side of the eyes (blinking), seeing rainbow rings around lights and eye pain. Unfortunately, it is usually irreversible. Glaucoma affects most often those over 40 with family histories of it as well as African Americans or those who are extremely nearsighted or diabetic.

There are two primary forms of glaucoma. Open-angle glaucoma is the more prevalent variety and occurs slowly as its drain area becomes blocked, leading to fluid build-up in the eye. Closed-angle glaucoma develops rapidly when an opening between iris and cornea narrows, blocking fluid from reaching its usual drainage channels in the eye trabecular meshwork and drain. Treatment for both types involves medicated eyedrops, laser treatments or surgery that increase draining out of eye, thus decreasing eye pressure.

Eye Stroke

High blood pressure and vision disturbance may arise when there are blocked arteries and veins in the retina – the tissue at the back of your eye that acts like a camera film focusing light into your eye and sending information back to your brain to form visual images. Blockages in retinal blood vessels may result in vision loss depending on their size, location, or both.

If a clot forms in the central retinal artery, patients may suffer complete or severe loss of vision; otherwise if one of its branches clots occurs instead, vision should usually remain preserved (although some people may lose a field that includes their own eye). This condition often strikes suddenly and without warning and tends to affect middle-aged adults more than anyone else; it’s more likely if you have heart disease, diabetes or another condition which leads to blockage of the arteries (such as high blood pressure).

Symptoms vary between individuals, but may include blindness in one or both eyes, blurred vision in affected areas, distortion of color vision such as jagged or mosaic patterns and difficulty focusing. Other people also experience headaches, eyelid drooping or facial drooping and generalized weakness of arms and legs.

Eye stroke is considered a medical emergency, so the NYEE ophthalmologists have developed an innovative protocol for quickly diagnosing this ocular disorder. It involves high-resolution retinal imaging at hospital entry points; thus eliminating on-site consultation and expediting treatment faster. This strategy has already shown promising results in protecting vision while helping improve outcomes for those suffering from this serious issue.

Preeclampsia

Preeclampsia is the most prevalent pregnancy-related high blood pressure disorder and one of the primary causes of maternal morbidity and mortality. This complex syndrome involves both placenta development as well as mother’s vascular and immune systems; scientists do not yet fully understand what triggers it.

Preeclampsia doesn’t often present with any noticeable symptoms, but if left untreated it can result in serious health complications for mother and fetus. Left untreated it can progress to life-threatening eclampsia which features seizures and liver damage; leading to headaches and vision disturbances for mom while forcing early delivery regardless of how far along she may be in her gestation.

Preeclampsia symptoms typically include high blood pressure, swelling of hands and feet, weight gain, protein in urine production, low platelet count, nausea/vomiting/upper abdominal pain; symptoms typically manifest themselves between 20th to 34th week gestation but they can appear any time during gestational period. Severe preeclampsia is diagnosed when both systolic blood pressure is 140 or higher and diastolic blood pressure 90 or greater; additionally there may be protein in urine production or end organ dysfunction both.

Doctors can often prevent preeclampsia and its complications by monitoring the blood pressure of women who are at risk, especially those who have had previous uncomplicated pregnancies. Medication may be prescribed to relieve nausea and vomiting caused by this condition, although delivery remains the best method. For gestationsal age less than 34 weeks gestational age patients a dose of corticosteroids may also be administered antenatally to promote lung maturity in some instances.

Central Serous Choroidopathy

Central Serous Chorioretinopathy (CSC) is an eye condition in which light is captured by thin tissues that capture it and translate it to visual recognition in your brain. CSC is characterized by fluid buildup beneath the retina and blurry vision; specifically it affects its central portion called macula which provides clear detailed vision. Unfortunately, no clear cause has yet been discovered for CSC but studies have linked it with psychosocial stress, type A personalities, corticosteroid medications use and even certain psychotherapies.

Sight loss in either eye is a condition known as monocularity and typically affects young and middle-aged adults; more male than female victims tend to experience it. The symptoms associated with it are blurry vision and an oval, dark spot in the middle of your visual field called a “scotoma,” as well as decreased contrast sensitivity and loss.

CSC occurs when the Retinal Pigment Epithelium (RPE) beneath the retina malfunctions, its primary job being to prevent fluid from leaking out from underneath it via blood vessel channels called choroid, but instead fluid leaks out through dysfunctional RPE and accumulates under it, leading to gradual vision loss or sometimes retinal detachments.

Your doctor can identify this condition by dilation of the eye and conducting a special fluorescein angiograph exam to detect fluid collection beneath the retina in the macular region. Most cases resolve without treatment; however, in rare cases laser photodynamic therapy, or PDT may be needed to seal off leakages and stop further retina damage – these outpatient procedures may help in managing CSC symptoms.
