What Is Angle Recession?

Angle recession is an eye injury in which the drainage angle between the cornea and iris is torn or damaged, often after blunt trauma. This damage can lead to changes in the iris root and the ciliary body, affecting how fluid drains from the eye. Over time, this may increase the risk of glaucoma. The condition itself is not visible without specialized examination.

What Causes Angle Recession?

The main cause is blunt trauma to the eye, such as from a ball, fist, or accident. The sudden compression and decompression forces split the delicate structures inside the anterior chamber angle. Some cases occur after penetrating injuries or surgery. Not all eyes with angle recession develop glaucoma, but the risk persists for life.

How Trauma Affects the Angle

The impact stretches the tissues that drain fluid from the eye, separating the circular muscle fibers of the ciliary body. This structural damage can alter fluid flow and pressure balance, which explains the lifetime monitoring requirement.

When to See Your Doctor

You should see your eye doctor if you notice sudden or persistent changes in your vision such as blurriness, flashes of light, floaters, or eye pain. Redness, swelling, or discharge that does not improve with basic care also warrants a checkup. Even if symptoms seem mild, getting a professional evaluation can help detect problems early and prevent complications. Regular eye exams are also important to monitor your overall eye health and keep your vision clear.

How Is Angle Recession Treated?

There is no treatment to reverse the structural tear, but regular monitoring helps detect glaucoma early. If pressure rises, eye drops, laser therapy, or surgery can help control it. People with a history of eye trauma should have lifelong check ups. Protective eyewear reduces risk of further injury.

How Is It Diagnosed?

Eye doctors diagnose angle recession using gonioscopy, which allows direct viewing of the anterior chamber angle. The exam reveals widened ciliary body bands or irregular structures. Visual field testing and optic nerve evaluation track any changes. Early detection is crucial for managing long term complications.

What Are the Long Term Risks?

The major concern is angle recession glaucoma, which can appear years after the initial injury. Regular eye pressure checks help detect this early. Patients should report symptoms like halos or blurred vision promptly. Prevention focuses on injury avoidance and continuous monitoring.

FAQs: Angle Recession

Can angle recession heal? The structural damage remains but does not always cause glaucoma.

When does glaucoma appear? It can develop months or even decades after injury.

Is both eyes affected? Usually only the injured eye shows recession.
