Primary Angle-Closure Glaucoma Suspect (Latent): Understanding the Condition and Its Treatment

Primary angle-closure glaucoma suspect (latent) is a condition where the angle between the iris and cornea is narrow, but the intraocular pressure (IOP) is still within the normal range. This condition is also known as "latent" or "subclinical" angle-closure glaucoma. If left untreated, latent angle-closure glaucoma can progress to primary angle-closure glaucoma and lead to blindness.

Symptoms and Causes of Latent Angle-Closure Glaucoma

Symptoms of latent angle-closure glaucoma are usually mild or absent, making it difficult to detect without a comprehensive eye exam. The cause of latent angle-closure glaucoma is related to the anatomy of the eye, specifically a narrow angle between the iris and cornea. This narrow angle can be caused by a variety of factors such as age, hyperopia (farsightedness), and certain types of cataracts.

Diagnosis and Treatment of Latent Angle-Closure Glaucoma

Latent angle-closure glaucoma is typically diagnosed through a comprehensive eye exam, including measuring the IOP, examining the angle of the eye, and examining the optic nerve. Gonioscopy, a procedure that allows the doctor to see the angle of the eye, is also done to confirm the diagnosis.

The main goal of treatment for latent angle-closure glaucoma is to prevent the progression to primary angle-closure glaucoma. This may include medications such as ocular hypotensive agents, which lower the IOP, and laser therapy such as laser peripheral iridotomy (LPI), which creates a small hole in the iris to allow the aqueous humor to flow more freely.

Monitoring

Latent angle-closure glaucoma is a chronic condition that requires regular monitoring to ensure that the treatment plan is effective. The patient will need to have regular eye exams to check the IOP, angle of the eye, and visual field. If the treatment is not effective, the treatment plan may need to be adjusted.

Prevention

While there is no known way to prevent latent angle-closure glaucoma, early detection and treatment can help prevent the progression to primary angle-closure glaucoma. It is important to have regular eye exams, especially if you have a family history of glaucoma or other risk factors such as age above 40, hyperopia, or certain types of cataracts.

In conclusion, Primary Angle-Closure Glaucoma Suspect (Latent) is a condition where the angle between the iris and cornea is narrow, but the intraocular pressure is still within the normal range. The main goal of treatment is to prevent the progression to primary angle-closure glaucoma. This may include medications, laser therapy and surgery. Regular monitoring is essential to ensure that the treatment plan is effective and to adjust it

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...
