Pterygium

 A pterygium is a triangular-shaped growth that forms on the conjunctiva, a clear tissue that lines the inner surface of the eyelids and covers the white part of the eye. It is most commonly found on the nasal side of the eye, near the inner corner of the eye.

Symptoms of a pterygium may include:

  • Triangular-shaped growth on the conjunctiva
  • Dryness, itching, or burning sensation in the eye
  • Sensitivity to light
  • Redness or swelling of the eye

Pterygia are most commonly caused by exposure to UV radiation, dust, wind, or other environmental irritants. They are more common in people who spend a lot of time outdoors, such as farmers, construction workers, and athletes. They are also more common in people who have dry eye syndrome, a condition in which the eyes do not produce enough tears or the tears evaporate too quickly.

In most cases, pterygia are benign and do not cause serious health problems. However, they can cause discomfort and may interfere with vision if they grow large enough to obstruct the line of sight. In rare cases, pterygia may transform into cancerous tumors.

Treatment for pterygia may include the use of lubricating eye drops or ointments to moisten the eye and reduce dryness and discomfort, as well as the use of sunglasses or other eye protection to reduce exposure to UV radiation and other irritants. In some cases, surgery may be necessary to remove the pterygium if it is causing significant discomfort or interfering with vision.

Prevention of Pterygia:

  • Wearing sunglasses or other protective eyewear to reduce exposure to UV radiation and other irritants
  • Using artificial tears or lubricating eye drops to prevent dryness of the eyes
  • Practicing good hygiene, such as washing your hands frequently and avoiding sharing towels, pillows, or other personal items
  • Seeking medical treatment for underlying conditions, such as dry eye syndrome, that may increase the risk of pterygia

If you are experiencing symptoms of a pterygium, it is important to see a healthcare provider for proper diagnosis and treatment. While pterygia are usually benign and do not cause serious health problems, it is important to have them evaluated to rule out other, more serious conditions.

Overall, pterygia are a common condition that can be effectively managed with proper care and prevention measures. By following your healthcare provider's recommendations and taking steps to reduce your exposure to allergens and irritants, you can help to prevent the development of pterygia and reduce the risk of complications.

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?

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...
