About Isolated iridoschisis

What is Isolated iridoschisis?

Isolated iridoschisis is a rare congenital eye disorder in which the iris (the colored part of the eye) is split into two layers. It is usually present at birth and is caused by a defect in the development of the iris. Symptoms may include blurred vision, increased sensitivity to light, and a visible split in the iris. Treatment is typically not necessary, but in some cases, surgery may be recommended to improve vision.

What are the symptoms of Isolated iridoschisis?

The main symptom of isolated iridoschisis is a visible split in the iris, which can be seen during an eye exam. Other symptoms may include blurred vision, glare, halos around lights, and increased sensitivity to light. In some cases, the split in the iris may cause the pupil to appear larger than normal.

What are the causes of Isolated iridoschisis?

The exact cause of isolated iridoschisis is unknown. However, it is believed to be caused by a combination of genetic and environmental factors. Possible causes include:

• Genetic mutations
• Trauma to the eye
• Infections
• Inflammation
• Autoimmune disorders
• Certain medications
• Radiation therapy
• Congenital abnormalities

What are the treatments for Isolated iridoschisis?

1. Laser photocoagulation: This procedure uses a laser to seal the edges of the iris defect, preventing further fluid leakage.

2. Intravitreal injections: This procedure involves injecting a medication into the eye to reduce inflammation and prevent further fluid leakage.

3. Surgical repair: This procedure involves surgically repairing the iris defect.

4. Artificial iris implantation: This procedure involves implanting an artificial iris to replace the damaged iris.

What are the risk factors for Isolated iridoschisis?

The risk factors for Isolated iridoschisis include:

1. Genetic predisposition: Isolated iridoschisis is often inherited in an autosomal dominant pattern, meaning that a person only needs to inherit one copy of the mutated gene from one parent to be affected.

2. Age: Isolated iridoschisis is more common in older individuals.

3. Gender: Isolated iridoschisis is more common in males than females.

4. Trauma: Trauma to the eye can cause the iris to tear, leading to isolated iridoschisis.

5. Certain medications: Certain medications, such as corticosteroids, can increase the risk of developing isolated iridoschisis.

Is there a cure/medications for Isolated iridoschisis?

There is no known cure for isolated iridoschisis. However, medications such as topical steroids, cycloplegic agents, and antiglaucoma medications may be used to reduce inflammation and improve vision. Surgery may also be recommended in some cases.
