Synechia

Synechia refers to an abnormal adhesion of the iris to either the cornea or the lens of the eye. This condition can lead to various complications, including impaired vision and increased intraocular pressure, potentially resulting in glaucoma.

Types of Synechia

Synechia can be classified into two main types:

• Anterior Synechia: This occurs when the iris adheres to the cornea. It can obstruct the drainage of the aqueous humor, leading to increased intraocular pressure.
• Posterior Synechia: This occurs when the iris adheres to the lens. It can cause the pupil to become irregularly shaped and can also lead to increased intraocular pressure.

Causes

Synechia can be caused by various factors, including:

• Uveitis: Inflammation of the uvea can lead to the formation of synechiae.
• Trauma: Physical injury to the eye can result in adhesions.
• Surgery: Post-surgical complications can sometimes lead to synechia.
• Infections: Certain eye infections can cause inflammation and subsequent adhesion formation.

Symptoms

The symptoms of synechia can vary depending on the severity and location of the adhesion. Common symptoms include:

• Blurred vision
• Eye pain
• Redness of the eye
• Sensitivity to light (photophobia)
• Irregularly shaped pupil

Diagnosis

Diagnosis of synechia typically involves a comprehensive eye examination, which may include:

• Slit-lamp examination: To visualize the anterior segment of the eye.
• Ophthalmoscopy: To examine the back of the eye.
• Tonometry: To measure intraocular pressure.

Treatment

Treatment for synechia aims to address the underlying cause and prevent complications. Options may include:

• Medications: Anti-inflammatory drugs or mydriatic agents to reduce inflammation and prevent further adhesion.
• Surgery: In severe cases, surgical intervention may be necessary to break the adhesions and restore normal eye function.

Prevention

Preventive measures for synechia include:

• Prompt treatment of eye infections and inflammations.
• Protective eyewear to prevent trauma.
• Regular eye check-ups, especially for individuals with a history of eye conditions.
