POSTERIOR UVEITIS

Posterior uveitis is an inflammation of the back of the eye, also known as the posterior segment. The posterior segment includes the retina, choroid, and the optic nerve. Posterior uveitis is a serious condition that can cause vision loss if left untreated.

Causes of Posterior Uveitis 

The causes of posterior uveitis are varied, and can include infections, autoimmune disorders, and other underlying health conditions. Some of the most common causes of posterior uveitis include:

-Toxoplasmosis: a parasitic infection caused by the Toxoplasma gondii parasite, which can affect the retina and the choroid. -Syphilis: a sexually transmitted infection caused by the bacteria Treponema pallidum, which can affect the retina and the choroid. -Herpes simplex virus: a viral infection caused by the herpes simplex virus, which can affect the retina. -Behcet's disease: a chronic autoimmune disorder that can affect the retina and the choroid. -Tuberculosis: a bacterial infection caused by Mycobacterium tuberculosis, which can affect the retina and the choroid.

Symptoms of Posterior Uveitis 

The symptoms of posterior uveitis can vary depending on the cause of the inflammation and the part of the eye that is affected. Some of the most common symptoms of posterior uveitis include:

-Floaters: small, dark spots that float in the field of vision -Blurred vision -Sensitivity to light -Redness and pain in the eye -Reduced vision or vision loss -A blind spot in the visual field

Diagnosis and Treatment 

The diagnosis of posterior uveitis typically begins with a comprehensive eye exam, including a dilated fundus examination, which allows the ophthalmologist to see the back of the eye. Additional tests, such as blood tests, chest x-ray and cultures may be needed to identify the underlying cause of the inflammation.

The treatment of posterior uveitis depends on the underlying cause of the inflammation. Treatment typically includes corticosteroid eye drops or injections to reduce inflammation and prevent complications. In some cases, other medications, such as methotrexate or mycophenolate mofetil, may also be used to suppress the immune system and prevent recurrent inflammation. Antiviral or antibiotics are used if the cause is identified as an infection. Additionally, underlying conditions such as tuberculosis or sarcoidosis need to be treated with systemic medications.

In conclusion, Posterior uveitis is an inflammation of the back of the eye, also known as the posterior segment. It can be caused by various factors such as infections, autoimmune disorders, and underlying health conditions. It is a serious condition that can cause vision loss if left untreated. Symptoms include floaters, blurred vision, sensitivity to light, redness and pain in the eye, reduced vision or vision loss, and a blind spot in the visual field. Diagnosis typically begins with a comprehensive eye exam, and treatment typically includes corticosteroid eye drops or injections to reduce inflammation and prevent complications. It's important to consult with an eye specialist if you suspect that you have posterior uveitis.

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...
