Management of Myopia

 Myopia, or nearsightedness, is a common 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. Myopia typically develops in childhood or adolescence and can progress as the individual grows. It is usually corrected with glasses, contact lenses, or refractive surgery.

In this article, we will cover the following topics:

  1. Overview of myopia management
  2. Glasses and contact lenses
  3. Refractive surgery
  4. Non-surgical approaches to myopia management

Overview of Myopia Management

The goal of myopia management is to correct the refractive error and improve visual acuity, as well as to slow or stop the progression of myopia. The approach to myopia management will depend on the individual's age, the severity of the myopia, and their preferences.

Myopia can be corrected with glasses, contact lenses, or refractive surgery. In addition, non-surgical approaches, such as eye exercises and vision therapy, may be recommended to help slow the progression of myopia.

It is important for individuals with myopia to have regular eye exams to monitor the health of the eye and the progression of the condition. Early detection and treatment can help prevent vision loss and other complications associated with myopia.

Glasses and Contact Lenses

Glasses and contact lenses are the most common methods of correcting myopia. They work by bending the light entering the eye in such a way that it focuses correctly on the retina, resulting in improved visual acuity.

Glasses: Glasses are lenses that are worn on the face and are held in place by a frame. They can be made with a single lens or with two lenses, depending on the degree of refractive error. Glasses can be prescribed for distance vision, near vision, or both.

Contact lenses: Contact lenses are small, curved lenses that are worn directly on the eye. They can be made from a variety of materials, including hard lenses, soft lenses, and gas-permeable lenses. Contact lenses can be prescribed for distance vision, near vision, or both.

Both glasses and contact lenses are effective at correcting myopia, but they may not be suitable for all individuals. Some people may prefer one over the other, or may not be able to wear either due to allergies, dry eye, or other conditions.

Refractive Surgery

Refractive surgery is a type of surgery that is used to correct refractive errors, including myopia. There are several types of refractive surgery, including:

  • LASIK: LASIK (laser-assisted in situ keratomileusis) is a laser surgery that is used to reshape the cornea and improve visual acuity. It is performed by an ophthalmologist and typically takes about 20-30 minutes.
  • PRK: PRK (photorefractive keratectomy) is a laser surgery that is used to reshape the cornea and improve visual acuity. It is similar to LASIK, but the outer layer of the cornea (the epithelium) is removed before the laser is applied, and the epithelium grows back over the treated area after the surgery.
  • Refractive lens exchange: Refractive lens exchange is a surgery in which the natural lens of the eye is removed and replaced with an artificial lens (intraocular lens, or IOL) to correct refractive errors. It is typically used in individuals with presbyopia (age-related farsightedness)

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...

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...
