What Is Juvenile Posterior Synechiae?

Juvenile posterior synechiae occur when the iris adheres to the lens capsule in children, often due to inflammation inside the eye. These adhesions restrict pupil movement and can interfere with fluid flow. Some children show light sensitivity or blurred vision, while others remain asymptomatic until the adhesion becomes extensive. The condition is commonly linked to uveitis, especially when inflammation is recurrent. Early treatment helps prevent long-term structural changes.

Causes of Juvenile Posterior Synechiae

Inflammatory activity inside the eye is the primary cause. Juvenile uveitis is often involved. Trauma or previous surgery can also promote adhesion formation. Prolonged pupil constriction increases risk. Identifying the trigger guides care.

Symptoms of Posterior Synechiae

Children may notice blurred or fluctuating vision. The pupil may appear irregular. Light sensitivity increases when inflammation is active. Some experience discomfort or ache. Symptoms vary depending on adhesion extent.

How It Is Diagnosed

Slit-lamp exam reveals iris-to-lens attachment. Pupil dilation tests show limited movement. Pressure checks help rule out secondary complications. History of uveitis supports the diagnosis. Imaging is used if deeper structures need evaluation.

Treatment for Posterior Synechiae

Dilation helps break early adhesions. Anti-inflammatory medication reduces recurrence. Long-standing adhesions may need surgical release. Monitoring helps detect pressure-related complications. Treatment focuses on controlling inflammation.

Frequently Asked Questions About Posterior Synechiae

Can this cause permanent damage?

Long-standing adhesions may affect pupil function.

Do they recur?

They can recur when inflammation returns.

Is vision affected?

Vision may blur when the pupil cannot move normally.

When should I seek care?

Seek care during inflammatory flare-ups or new visual changes.
