Hypertension and vision problems -
William White shines a bright light in his patient's eye, he's looking for more than just vision problems. He's searching for clues indicating the effects of high blood pressure, or hypertension, and what he finds could help prevent heart attacks, strokes and other serious health problems far beyond the eye.
They'll push on each other and cross, like two hoses in a confined space. And that can cause a whole range of vision issues. Vision symptoms may not show up for years. But ultimately, high blood pressure can result in hypertensive retinopathy, blood vessel damage causing blurred vision or loss of sight; choroidopathy, a buildup of fluid under the retina that can distort or impair vision; or optic neuropathy, a blood flow blockage that can kill nerve cells and cause vision loss.
Similarly, high blood pressure may not reveal itself for decades before causing a heart attack or stroke, which earns its grim description as the "silent killer.
That is why detecting high blood pressure early — and treating it with diet, exercise and medication — is crucial, and why White says eye doctors are on the front lines of the battle. Why are you checking my blood pressure? A study reported in the journal Hypertension underscored the point.
Researchers checked about 2, patients with high blood pressure for hypertensive retinopathy, then tracked them for an average of 13 years. AV crossing changes occur when a thickened arteriole crosses over a venule and subsequently compresses it as the vessels share a common adventitious sheath.
The vein, in turn, appears dilated and torturous distal to the AV crossing. Seen in patients with severely increased BP; characterized by the disruption of the blood-brain barrier and leakage of blood and plasma into the vessel wall disrupting the autoregulatory mechanisms.
In this stage, retinal signs occur such as retinal hemorrhage flame-shaped and dot blot , hard exudate formation, necrosis of smooth muscle cells and retinal ischemia cotton-wool spots.
Severe intracranial hypertension leads to optic nerve ischemia and edema papilledema. Also, fibrinoid necrosis of choroidal arterioles occurs leading to segmental infarction of choriocapillaries. This gives rise to:. Hypertensive retinopathy is usually asymptomatic and is diagnosed on fundoscopic features.
The following are signs of hypertensive retinopathy. In a study by Wong et al. The signs are AV nicking, focal arteriolar narrowing as this is associated with arteriosclerosis , microaneurysms, cotton wool spots, retinal hemorrhages dot blot and flame-shaped , and decreased AV ratio.
The main purpose of screening for hypertensive retinopathy is that retinal vessels are the only blood vessels visible on routine examination.
The effects of chronically elevated HTN are easily visible in the eye as hypertensive retinopathy and choroidopathy, and this reflects the vascular changes occurring in other systems.
Ophthalmologists and general physicians should work in collaborations to ensure that hypertensive patients are efficiently screened, and timely managed to reduce the risk of ocular and systemic morbidity and mortality.
Important to note is that BP should be lowered in a controlled fashion. This is crucial to prevent ischemic damage to vital organs such as optic nerve and brain. Chronic hypertensive retinopathy rarely causes significant visual loss. The retinal changes can be halted when hypertension is treated.
However, arteriolar narrowing and AV changes persist. Hypertension has effects on multiple systems, and it is important to have care coordination between the physician, physician assistant, nurse practitioner, ophthalmologist, nephrologist, and cardiologist to ensure early detection and control of hypertension and improve patient outcomes.
Patients with hypertension need to be informed that they should follow up regularly with an ophthalmologist for a complete eye assessment. In addition, patients need to be educated about the importance of compliance with antihypertensive medications.
In most patients, hypertensive retinopathy does not cause vision loss as long as the hypertension is treated. However, if the blood pressure remains untreated, it can lead to vision loss within a short period of time. The cause of the vision loss is either due to retinal pigmentary changes or secondary to optic atrophy, neither of which is reversible.

Continuing Education Activity Poorly controlled hypertension HTN affects several systems such as the cardiovascular, renal, cerebrovascular, and retina.
Introduction Poorly controlled hypertension HTN affects several systems such as the cardiovascular, renal, cerebrovascular, and retina. Etiology Apart from essential and secondary hypertension, there are other factors which play an important role in the development of hypertensive retinopathy.
Epidemiology The severity and duration of hypertension are directly proportional to the incidence of hypertensive retinopathy as studied by Erden et al. Pathophysiology Retinal blood vessels have distinct features, which differentiate them from other blood vessels [10] : The absence of sympathetic nerve supply.
History and Physical Clinical Features [4] Hypertensive retinopathy is usually asymptomatic and is diagnosed on fundoscopic features. Retinal hemorrhages: Dot-blot hemorrhages: Bleeding in the inner retinal layer. Retinal exudates: Hard exudates: Lipid deposits in the retina.
Soft exudates: These are also known as cotton wool spots which appear due to ischemia of the nerve fibers. Keith-Wagner- Barker classification Group 1: Slight constriction of retinal arterioles.
Moderate hypertensive retinopathy: Referral to a physician is essential to exclude other associated factors like diabetes mellitus and to check for any cardiovascular abnormalities. Routine care including BP control and monitoring is a must. Severe hypertensive retinopathy: Requires urgent treatment and referral as it has the strongest association with mortality.
Other systems such as renal, cardiovascular, and brain should be monitored for signs of TOD. Differential Diagnosis The other conditions which present with optic disc swelling are: Diabetic papillopathy. Prognosis Chronic hypertensive retinopathy rarely causes significant visual loss.
Complications Complications include [14] : Retinal artery occlusion. Diabetic retinopathy DR : Both hypertensive retinopathy and DR together in a patient is called as mixed retinopathy. HTN is also known to be a major risk factor for the progression of DR.

Why High Blood Pressure Is Bad for Your Eyes Hypertension damages blood vessels throughout your body, including those in your eyes. If the blood vessels in your eyes are damaged or clogged with plaque, you may eventually begin to experience problems with your vision due to: Hypertensive Retinopathy Nonarteritic Ischemic Optic Neuropathy NA-AION Central Serous Choroidopathy Glaucoma Hypertensive Retinopathy Affects the Light Sensing Cells in Your Eyes The light-sensing cells that make up the retina convert the rays into electrical signals.
Symptoms of hypertensive retinopathy include: Cloudy Vision Blurred Vision Loss of Vision Headaches NA-AION Damages an Important Vision Pathway High blood pressure may also affect blood flow to the optic nerve, the pathway between the eye and the brain.
Fluid Build-Up Causes Vision Loss in Central Serous Choroidopathy Leaking fluid from the choroid, a layer of tissue under the retina, can interfere with your vision if you have high blood pressure. Symptoms of central serous choroidopathy include: Blurry Central Vision Straight Lines That Appear Crooked Dull Colors A Dark Spot in Your Central Vision Your eyesight may improve in a few months on its own if you have central serous choroidopathy.
High Blood Pressure Could Increase Your Risk of Glaucoma Glaucoma occurs when the pressure inside your eye becomes too high and damages the optic nerve. Preventing Vision Conditions Related to Hypertension Lowering your blood pressure can help you avoid eye conditions that could cause vision loss.

In addition, several retinal diseases such as retinal vascular occlusion artery and vein occlusionretinal arteriolar emboli, macroaneurysm, ischemic optic neuropathy and age-related macular degeneration may also be related to hypertension; however, there is as yet no evidence that treatment of hypertension prevents vision loss from these conditions. In management of patients with hypertension, physicians should be aware of the full spectrum of the relationship of blood pressure and the eye.
