Iridocorneal adhesions, also called peripheral anterior synechiae, are areas where the iris attaches to the cornea near the drainage angle. These adhesions block fluid outflow and can increase eye pressure. They may form slowly or appear after inflammation or injury. People often notice no symptoms until pressure rises. Exams help determine how extensive the adhesions are.
read more about iridocorneal adhesions pas ...Inflammation is a frequent cause of adhesion formation. Angle-closure episodes can pull the iris forward and create attachment points. Trauma may damage the drainage angle and promote scarring. Long-standing high pressure also contributes. Understanding the cause helps with long-term management.
Most people notice no early symptoms. As pressure increases, discomfort or blurred vision can develop. Halos may appear around lights. In advanced cases, peripheral vision becomes limited. Symptoms reflect how much of the angle is affected.
Gonioscopy shows where the iris is attached to the cornea. Pressure measurements reveal whether flow is blocked. Imaging assists when angle structures are difficult to view. History provides clues about inflammation, trauma, or closure events. Diagnosis helps determine whether treatment is necessary.
Treatment focuses on lowering eye pressure. Medication supports fluid outflow. Laser work may help in selected cases. Surgery is used when adhesions are extensive. Regular follow-up helps track angle stability.
No. Small adhesions may not affect flow.
Most become permanent once formed.
Not usually unless pressure rises.
Seek care for pressure-related symptoms or new halos.
