Blood pressure is affected by constriction and dilation of?
Blood vessels. Constriction of blood vessels increases blood pressure by reducing the space for blood flow, while dilation of blood vessels decreases blood pressure by increasing the space for blood flow.
What are the three components of the cardiovascular system?
The three components of the cardiovascular system are the heart, blood vessels (arteries, veins, and capillaries), and blood. The heart pumps blood through the blood vessels, which transport oxygen, nutrients, and waste products throughout the body.
What is a corkscrew vessel of the eye?
Type of new vessel growth typically seen in an eye experiencing oxygen deprivation. It is imperitive that one keeps their blood sugar and pressure under control to stave off more of these vessels developing.
What is angio?
It is a flowering plant.
What is a retinal scan?
A retinal scan is a biometric technology that uses unique patterns of blood vessels in the retina to identify individuals. It is an advanced form of identification that is often used for security purposes due to its high level of accuracy.
What is retinal hemorrhage?
Retinal hemorrhage is the abnormal bleeding of the blood vessels in the retina, the membrane in the back of the eye.
What conditions is retinal cryopexy used to treat?
retinal breaks or detachments; retinal ischemia (retinal tissue that lacks oxygen); neovascularization (proliferation of blood vessels in the retina); Coats' disease
What is the retinal damage marked by aneurysmal dilation of blood vessels caused by?
Diabetic Retinopathy
What is retinal damage marked by aneurysm dilation of blood vessels caused by?
Diabetic Retinopathy
Can drinking Diet Coke cause detached retina?
Moderate to severe consumption of diet soda which has Aspartame as artificial sweetener can increase the risk of optic nerve swelling, optic nerve atrophy, retinal atrophy and retinal degeneration which can predispose to retinal detachment.. They found that Aspartame can cause damage to retinal blood vessels and increase the risk of leakage of blood and fluid from these damaged vessels.
A radiographic study of the blood vessels in the retina of the eye is known as what?
A radiographic study of the blood vessels in the retina of the eye is known as fluorescein angiography. This procedure involves the intravenous injection of a fluorescent dye, which highlights the retinal blood vessels during imaging. It is commonly used to diagnose and monitor various retinal conditions, such as diabetic retinopathy and age-related macular degeneration.
What is the medical term meaning radiographic study of the blood vessels in the retina of the eye?
Fluorescein angiography is the medical term meaning radiographic study of the blood vessels of the retina. This process can examine retinal vessels in the case of diabetes.
How is retinopathy diagnosed?
The damaged retinal blood vessels and other retinal changes are visible to an eye doctor when an examination of the retina (fundus exam) is done. This can be done using a hand-held instrument called an ophthalmoscope.
What alternative treatment is used for retinal hemorrhages?
Laser surgery by an opthalmologist is a common treatment for retinal hemorrhages, in which a laser beam is used to remove or seal off damaged or bleeding blood vessels in the retina.
What does a normal angiogram reveal?
test results should display a normal and unimpeded flow of blood through the vascular system. Fluorescein angiography should result in no leakage of fluorescein dye through the retinal blood vessels.
What causes bleeding in your eye near the optic disc?
Bleeding near the optic disc can be caused by several factors, including diabetic retinopathy, which leads to the formation of new, fragile blood vessels that can rupture, and hypertension, which can cause damage to the retinal blood vessels. Other potential causes include retinal vein occlusion, trauma, and certain inflammatory conditions. Such bleeding can lead to vision problems and requires prompt evaluation by an eye care professional.
What Of the blood vessels?
Blood Vessels-are the passageway of blood.
