Primary Open-Angle Glaucoma (POAG)

Primary open-angle glaucoma (POAG) is a chronic eye condition characterized by increased pressure within the eye, known as intraocular pressure (IOP), which can cause damage to the optic nerve and lead to vision loss. POAG is the most common type of glaucoma and is most commonly seen in individuals over the age of 40.

Symptoms of POAG

POAG is a gradual process that develops over time, and early stages often have no symptoms. As the condition progresses, symptoms may include:

  • Loss of peripheral vision, also known as tunnel vision
  • Halos around lights
  • Blurred vision
  • Eye pain or discomfort
  • Redness in the eye

Causes of POAG

The exact cause of POAG is not known, but it is believed to be the result of a malfunction in the eye's drainage system. The eye's drainage system is responsible for draining the fluid that fills the eye, and a malfunction can cause the fluid to build up, increasing the pressure within the eye.

Risk Factors

There are several factors that can increase an individual's risk of developing POAG, including:

  • Age: POAG is most commonly seen in individuals over the age of 40.
  • Family history: POAG tends to run in families, so individuals with a family history of the condition are at an increased risk.
  • Race: POAG is more common in African Americans and Hispanic Americans than in individuals of other races.
  • High blood pressure: Individuals with hypertension are at an increased risk of developing POAG.
  • Diabetes: Individuals with diabetes are at an increased risk of developing POAG.

Diagnosis and Treatment

POAG is usually diagnosed during a routine eye exam by an ophthalmologist. A complete eye exam, including measurements of the eye's intraocular pressure and examination of the optic nerve, is needed to diagnose the condition.

Treatment of POAG typically involves medication and surgery. Medications, such as eye drops, can be used to lower the eye's intraocular pressure. Surgery may be needed in severe cases or when medications are not effective.

Prognosis

POAG is a chronic condition that can cause permanent vision loss if left untreated. With early detection and treatment, the progression of the condition can be slowed or even stopped. It is important for individuals over the age of 40 to have regular eye exams to ensure that any potential vision problems are detected and treated as soon as possible.

Prevention

There is no known way to prevent POAG, but early detection and treatment can help prevent vision loss. Individuals over the age of 40 should have regular eye exams to ensure that any potential vision problems are detected and treated as soon as possible.

In conclusion, Primary Open-Angle Glaucoma (POAG) is a chronic eye condition characterized by increased pressure within the eye, known as intraocular pressure (IOP), which can cause damage to the optic nerve and lead to vision loss. It is the most common type of glaucoma and is most commonly seen in individuals over the age of 40. The exact cause of POAG is not known, but it is believed to be the result of a malfunction in the eye's drainage system. Risk factors include age, family history, race, high blood pressure and diabetes. POAG is usually diagnosed during a routine eye exam and treated with medication and surgery. Early detection and treatment can help prevent vision loss. Individuals over the age of 40 should have regular eye exams.

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...
