What Is Iris Bombe?

Iris bombe is a forward bulging of the iris caused by trapped fluid behind it. The iris bows toward the front of the eye when the pupil blocks fluid flow from the back chamber. This raises pressure and narrows the drainage angle. People may notice eye pain or blurred vision when pressure spikes. The condition requires prompt evaluation to prevent long-term damage.

What Causes Iris Bombe?

Pupillary block is the most common cause. Inflammation can create adhesions that stick the iris to the lens. Surgical changes may alter fluid movement. Trauma can disrupt normal flow as well. Identifying the cause helps determine which treatment is needed.

Symptoms of Iris Bombe

People may feel eye pressure or notice halos around lights. Vision can become blurry when the angle narrows sharply. Pain may appear in acute cases. Some notice redness and nausea during pressure spikes. Symptoms often progress quickly when the angle closes.

How Is Iris Bombe Diagnosed?

Doctors inspect the iris contour for forward bowing. Pressure measurements help assess severity. Gonioscopy shows whether the angle is narrowing. Imaging may reveal fluid buildup and iris configuration. Diagnosis helps determine whether immediate decompression is required.

How Is Iris Bombe Treated?

Laser procedures create a small opening to restore fluid movement. Medication helps reduce pressure during acute episodes. Adhesion release may be needed if inflammation caused the blockage. Long-term follow-up monitors angle health. Early treatment protects the optic nerve.

Frequently Asked Questions About Iris Bombe

Is this an emergency?

It can be, especially with high pressure.

Can it recur?

Yes, if the underlying blockage persists.

Does laser treatment help?

Yes. It restores fluid flow in most cases.

When should I seek care?

Seek care for sudden eye pain or halos.
