VASCULAR DISTURBANCES

 Vascular disturbances refer to a group of conditions that affect the blood vessels in the body, including the eyes. These conditions can be caused by a variety of factors, including genetics, disease, and injury. They can lead to serious complications such as vision loss, blindness, and even death. In this article, we will discuss the causes, symptoms, and treatments for some of the most common vascular disturbances of the eyes, as well as ways to manage the condition.

  1. Retinal Vein Occlusion (RVO)

Retinal vein occlusion (RVO) is a condition in which the blood vessels in the retina become blocked, preventing blood from flowing properly. This can cause swelling and damage to the retina, leading to vision loss. RVO is most commonly caused by hypertension, diabetes, and hyperviscosity syndromes.

Symptoms of RVO include sudden vision loss, floaters, and blurred vision. Treatment options include laser therapy, injection of medications to reduce swelling, and medications to control hypertension and diabetes.

  1. Central Retinal Artery Occlusion (CRAO)

Central retinal artery occlusion (CRAO) is a condition in which the central retinal artery, which supplies blood to the retina, becomes blocked. This can cause sudden and severe vision loss in the affected eye. CRAO is most commonly caused by emboli, which are small clumps of material that can travel through the bloodstream and block blood vessels.

Symptoms of CRAO include sudden vision loss, eye pain, and a red eye. Treatment options include use of medications such as hyperbaric oxygen therapy, and in some cases, surgical intervention.

  1. Diabetic Retinopathy

Diabetic retinopathy is a complication of diabetes that affects the blood vessels in the retina. It can cause vision loss or blindness. Diabetic retinopathy is caused by changes in the blood vessels of the retina due to high blood sugar levels.

Symptoms of diabetic retinopathy include blurred vision, floaters, and difficulty seeing at night. Treatment options include laser therapy, injection of medications to reduce swelling, and medications to control blood sugar levels.

  1. Age-Related Macular Degeneration (AMD)

Age-related macular degeneration (AMD) is a condition that affects the macula, which is the part of the retina responsible for central vision. It is the leading cause of blindness among older adults. AMD is caused by a combination of genetic and environmental factors, such as smoking, high blood pressure, and a diet high in saturated fats.

Symptoms of AMD include blurred vision, difficulty seeing fine details, and a dark or empty area in the center of vision. Treatment options include laser therapy, injection of medications to reduce swelling, and vitamin and mineral supplements.

  1. Hypertensive Retinopathy

Hypertensive retinopathy is a complication of hypertension that affects the blood vessels in the retina. It can cause vision loss or blindness. Hypertensive retinopathy is caused by changes in the blood vessels of the retina due to high blood pressure.

Symptoms of hypertensive retinopathy include blurred vision, floaters, and difficulty seeing at night. Treatment options include medications to control blood pressure, and in some cases, laser therapy.

ABETALIPOPROTEINEMIA (BASSEN-KORNZWEIG SYNDROME) Retinopathy

Image
Abetalipoproteinemia, also known as Bassen-Kornzweig syndrome, is a rare genetic disorder that affects the body's ability to absorb and transport fats and fat-soluble vitamins. One of the ways that abetalipoproteinemia can affect the eyes is by causing retinitis pigmentosa, a condition that causes vision loss. Retinitis pigmentosa is a degenerative eye disease that affects the retina (the light-sensitive layer at the back of the eye). It is characterized by the gradual loss of photoreceptor cells (cells that detect light and send signals to the brain) and the accumulation of pigment in the retina. This can cause vision loss and may lead to blindness in severe cases. Abetalipoproteinemia can also cause optic atrophy, a condition in which the optic nerve (the nerve that carries visual information from the eye to the brain) becomes thin and weak. This can cause vision loss and other visual problems. In conclusion, abetalipoproteinemia can affect the eyes by causing reti...

What is myopia?

Image
Myopia is nearsightedness and this condition of eye occurs when the power of eye is increased from the normal powers of eye. The normal powers of eye is 58DS and the eye with >58DS eye power will be marked as myopic eye.  Definition   When parallel light rays coming from the infinity focus Infront of the retina while the accommodation should be at rest this condition of eye is known as myopia.

Scleritis

Scleritis 👌is a painful inflammation (swelling) the sclera. The tough, fibrous tissues of the sclera form a protective outer layer for the eye and make up 83 percent of the eye’s surface. In almost half of all cases, scleritis is associated with an underlying autoimmune disorder such as rheumatoid arthritis. There are two main types of scleritis: anterior and posterior. Anterior scleritis, the most common type, affects the front portion of the sclera. There are three types of anterior scleritis: Diffuse scleritis is the most common type and fortunately the most treatable. This type displays widespread redness and inflammation throughout the whole or a portion of the front portion of the sclera.     Nodular scleritis, is characterized by the presence of nodules , often tender to the touch, on the surface of the eye.     Necrotizing scleritis is the most severe form of anterior scleritis. It has the ability to destroy scleral tissues an...
