Diseases of Vitreous

The vitreous, also known as the vitreous humor, is a clear gel-like substance that fills the space between the lens and the retina in the human eye. The vitreous plays a crucial role in maintaining the health and proper functioning of the eye, but it can also be affected by various diseases.

Vitreous Detachment

Vitreous detachment is a common condition that occurs when the vitreous separates from the retina. This can cause floaters, which are small spots or strings that appear in the field of vision, and flashes of light. Vitreous detachment is a normal part of aging and is not typically harmful, but it can be a sign of a more serious problem, such as a retinal detachment, which requires immediate medical attention.

In some cases, the vitreous may pull on the retina as it detaches, causing a retinal detachment. This can lead to a loss of vision if not treated promptly. Symptoms of a retinal detachment include floaters, flashes of light, and a sudden loss of vision.

Vitreous Hemorrhage

Another problem that can affect the vitreous is called vitreous hemorrhage, which occurs when blood enters the vitreous. This can cause floaters, as well as a loss of vision. Vitreous hemorrhage can be caused by a variety of conditions, including diabetes, high blood pressure, and eye injuries.

Vitreous hemorrhage can be caused by a variety of underlying conditions, including diabetes, hypertension, and retinal vein occlusion. It can also occur as a complication of eye surgery. Symptoms of vitreous hemorrhage include floaters, a loss of vision, and a red or dark spot in the field of vision.

Inflammation of Vitreous

Inflammation of the vitreous, also known as vitritis, can occur as a result of an infection, injury, or autoimmune disorder. Symptoms of vitritis include eye pain, redness, and sensitivity to light. In severe cases, vitritis can cause vision loss. Treatment of vitritis typically involves the use of anti-inflammatory medications and sometimes antibiotics if the cause is an infection.

Tumors

Tumors can also affect the vitreous and its surrounding structures. The most common tumors affecting the vitreous are benign tumors such as the pigmented and non-pigmented epithelial cells and malignant tumors such as the primary vitreoretinal lymphoma. These tumors can cause floaters, visual disturbances, and even blindness if not treated promptly.

Conclusion

The vitreous is a clear gel-like substance that fills the space between the lens and the retina in the human eye. It plays a crucial role in maintaining the health and proper functioning of the eye. However, it can also be affected by various diseases, such as vitreous detachment, vitreous hemorrhage, inflammation, and tumors. These diseases can cause symptoms such as floaters, flashes of light, and loss of vision. Prompt diagnosis and treatment are important to prevent vision loss and other complications.

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...
