Coronary Cataract: Definition, Causes, Symptoms, and Treatment

 Coronary cataract refers to a specific type of cataract characterized by the presence of opacities on the outer edge of the lens, known as the "crown" or "corona." This type of cataract can cause a decrease in vision and can be caused by a variety of factors. In this article, we will discuss the definition, causes, symptoms, and treatment options for coronary cataract.

Definition

A coronary cataract is a type of cataract characterized by the presence of opacities on the outer edge of the lens, known as the "crown" or "corona." These opacities can cause a decrease in vision by scattering light as it passes through the lens. Coronary cataracts can occur in any area of the lens and can be caused by a variety of factors.

Causes

Coronary cataracts can be caused by a variety of factors, including:

  • Age: Coronary cataracts are more common in older individuals.
  • Genetics: Some people may be more prone to developing coronary cataracts due to genetic factors.
  • Medical conditions: Certain medical conditions, such as diabetes, can increase the risk of developing coronary cataracts.
  • Medications: Certain medications, such as corticosteroids, can increase the risk of developing coronary cataracts.

Symptoms

The symptoms of coronary cataracts can vary depending on the location and severity of the opacities. Some common symptoms include:

  • Blurred vision: The formation of opacities on the outer edge of the lens can scatter light, causing blurred vision.
  • Glare and halos: Coronary cataracts can cause glare and halos around lights, making it difficult to see at night.
  • Faded colors: The opacities on the outer edge of the lens can make colors appear faded and less vibrant.
  • Distorted vision: The opacities on the outer edge of the lens can cause distortions in vision, such as straight lines appearing curved.
  • Decreased visual acuity
  • Difficulty seeing in bright light

Treatment

The treatment of coronary cataracts depends on the severity of the condition and the symptoms that the patient is experiencing. In the early stages of coronary cataracts, glasses or contact lenses may be used to correct vision. However, as the condition progresses, surgery may be necessary to remove the opacities and replace the cloudy lens with an artificial one.

The most common surgical procedure for coronary cataract is called phacoemulsification. This procedure uses ultrasound energy to break up the lens and remove the opacities. An artificial lens, called an intraocular lens (IOL), is then inserted into the eye to replace the natural lens.

After the surgery, the patient will need to use eye drops to help prevent infection and inflammation, as well as to aid in healing. Most patients can return to normal activities within a week, but it may take several weeks for the eye to fully heal and for vision to improve.

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...
