MYOPIA

Myopia, also known as nearsightedness, is a common refractive error in which the eye is unable to focus light properly onto the retina. This results in difficulty seeing objects that are far away, while objects that are closer may appear clear. Myopia typically begins in childhood and can continue to progress throughout the teenage years. In this article, we will discuss the causes, symptoms, and treatment options for myopia.

Causes of Myopia

Myopia is caused by an elongated shape of the eye, which causes light to be focused in front of the retina rather than directly on it. This can be due to a variety of factors, including genetics, environmental factors, or a combination of both. Some specific causes of myopia may include:

  • Heredity: Myopia tends to run in families, so it is likely that if one or both parents are nearsighted, their children may also be at an increased risk of developing myopia.
  • Environmental factors: Studies have shown that children who spend less time outdoors and more time reading, studying, or using electronic devices may be at an increased risk of developing myopia.
  • Other medical conditions: Some medical conditions, such as diabetes or high blood pressure, may increase the risk of developing myopia.

Symptoms of Myopia

The most common symptom of myopia is difficulty seeing objects that are far away, while objects that are closer may appear clear. Other symptoms may include:

  • Squinting or straining to see distant objects
  • Headaches, especially after reading or other close work
  • Eye fatigue or tired eyes after reading or other close work

Treatment Options for Myopia

The treatment for myopia will depend on the severity of the condition and the individual's age. Some treatment options may include:

  • Glasses or contact lenses: For mild to moderate cases of myopia, glasses or contact lenses may be sufficient to correct the refractive error and improve vision.
  • Refractive surgery: In some cases, refractive surgery may be an option to permanently correct the shape of the eye and improve vision. Some common types of refractive surgery for myopia include LASIK (laser-assisted in situ keratomileusis) and PRK (photorefractive keratectomy).
  • Orthokeratology: Orthokeratology, also known as corneal reshaping, involves wearing special contact lenses at night that temporarily reshape the cornea and improve vision during the day. This can be a good option for individuals who do not want to wear glasses or contact lenses during the day.

It is important to note that myopia can continue to progress during the teenage years, so regular eye exams are important to monitor the condition and determine the appropriate treatment.

Conclusion

Myopia is a common refractive error that causes difficulty seeing objects that are far away. It can be caused by genetics, environmental factors, or a combination of both, and is more common in children and teenagers. Treatment options for myopia may include glasses or contact lenses, refractive surgery, or orthokeratology. Regular eye exams are important to monitor the condition and determine the appropriate treatment.

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...
