Axial Ametropia

 Axial ametropia is a type of vision problem that is caused by the length of the eye being too long or too short. This condition is also known as axial length error or axial myopia or hyperopia.

In a normal eye, the length of the eye is ideal for focusing light correctly on the retina at the back of the eye. If the eye is too long or too short, the light is focused incorrectly, leading to vision problems.

Myopia, or nearsightedness, is a type of axial ametropia that is caused by the eye being too long. In myopia, the light is focused in front of the retina rather than on it, leading to difficulty seeing objects that are far away, but objects that are closer can be seen clearly.

Hyperopia, or farsightedness, is the opposite of myopia and is caused by the eye being too short. In hyperopia, the light is focused behind the retina rather than on it, leading to difficulty seeing objects that are close, but objects that are farther away can be seen clearly.

There are several factors that can contribute to the development of axial ametropia. Genetics play a role in the shape and size of the eye, and certain genetic conditions can increase the risk of developing axial ametropia. Environmental factors, such as excessive reading or computer use, can also contribute to the development of axial ametropia.

There are several methods for correcting axial ametropia and improving vision. The most common method is the use of eyeglasses or contact lenses, which can help to correct the refractive power of the eye and improve vision. Surgery is another option for correcting axial ametropia, but it is generally reserved for more severe cases.

One type of surgery that is commonly used to correct axial ametropia is laser-assisted in situ keratomileusis (LASIK). This procedure involves the use of a laser to reshape the cornea and correct its curvature. The procedure is usually performed on an outpatient basis and takes only a few minutes to complete.

Another type of surgery that is used to correct axial ametropia is refractive lens exchange (RLE). This procedure involves the removal of the natural lens of the eye and its replacement with an artificial lens. The artificial lens is chosen to correct the refractive power of the eye and improve vision.

It is important to regularly visit an eye doctor to check for any vision problems or eye conditions that may be present. Early detection and treatment of axial ametropia can help to prevent vision loss and ensure that the eye is functioning properly. If you are experiencing vision problems or are concerned about your eye health, it is important to speak with an eye care professional.

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...
