Peripheral Fundus Changes in Myopia

 Peripheral fundus changes are structural changes that occur in the peripheral (side) portion of the fundus, or the back of the eye, in individuals with myopia, or nearsightedness. Myopia is a refractive error of the eye in which the eyeball is too long or the cornea is too curved, causing light rays to focus incorrectly on the retina and resulting in a blurry image of distant objects. As the eyeball grows and becomes more elongated in myopia, various structural changes can occur in the peripheral fundus, which is the portion of the eye outside of the central visual field. These structural changes can have significant implications for vision and eye health.

In this article, we will cover the following topics:

  1. What is the fundus?
  2. Structural changes in the peripheral fundus in myopia
  3. Impact of peripheral fundus changes on vision and eye health
  4. Management and prevention of peripheral fundus changes in myopia

What is the Fundus?

The fundus is the back part of the eye, which includes the retina, the optic disc, and the choroid. The retina is the light-sensitive layer of tissue at the back of the eye that receives light and converts it into electrical signals that are sent to the brain. The optic disc is the portion of the eye where the optic nerve and blood vessels enter the retina. The choroid is a layer of tissue between the retina and the sclera (the white outer layer of the eye) that contains blood vessels that nourish the retina.

The fundus can be examined using specialized equipment, such as an ophthalmoscope or a fundus camera, which allows the eye doctor to see the retina, optic disc, and choroid in detail. The appearance of the fundus can provide important information about the health of the eye and the retina.

Structural Changes in the Peripheral Fundus in Myopia

In individuals with myopia, the eyeball grows and becomes more elongated as the condition progresses. This elongation can lead to various structural changes in the peripheral fundus, including:

  • Retinal detachment: Retinal detachment is a serious condition in which the retina becomes separated from the back of the eye. It can be caused by a variety of factors, including myopia, trauma, inflammation, or degenerative changes in the eye. Retinal detachment can cause vision loss if not treated promptly.
  • Choroidal neovascularization: Choroidal neovascularization is the growth of new blood vessels in the choroid, which can be a sign of age-related macular degeneration or other underlying conditions. These new blood vessels are fragile and can leak fluid or blood, leading to vision loss.
  • Retinal thinning: Retinal thinning is a condition in which the retina becomes thinned or atrophic, which can be a sign of myopia or other underlying conditions. Retinal thinning can lead to vision loss.

Impact of Peripheral Fundus Changes on Vision and Eye Health

Peripheral fundus changes in individuals with myopia can have significant implications for vision and eye health. Retinal detachment, choroidal neovascularization, and retinal thinning can all lead to vision loss, and early detection and treatment is important to prevent further vision loss.

In addition, peripheral fundus changes may indicate the presence of underlying eye conditions, such as age-related macular degeneration or other degenerative changes in the eye, that require medical attention. It is important for individuals with myopia to have regular eye exams to monitor the health of the peripheral

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...
