What Is Gonioplasty?

Gonioplasty is a laser procedure used to reshape the eye's drainage angle. Doctors perform it when the angle is narrow or at risk of closure. The laser creates tiny changes that pull tissue away from the drainage area. This helps fluid move more freely inside the eye. The procedure supports safer long-term pressure levels.

Why Do Doctors Perform Gonioplasty?

It helps widen the drainage angle when tissue crowding threatens fluid flow. Doctors assess how narrow the angle is before planning the procedure. They also review pressure levels and overall eye structure. The treatment is often chosen to prevent angle-closure episodes. Patterns from imaging guide the decision.

What Improvements Can Gonioplasty Create?

  • Better angle access.
  • Lower risk of sudden closure.
  • Reduced pressure fluctuations.
  • Improved fluid movement.

How Do Doctors Carry Out Gonioplasty?

They position a special lens on the eye while applying focused laser spots to the angle tissues. The laser reshapes the region without cutting. Doctors track early healing to confirm good tissue response. Pressure readings are reviewed at follow-up visits. Plans depend on the results.

How Does Gonioplasty Help When the Drainage Angle Is Narrow?

Gonioplasty is a laser procedure used to pull crowded angle tissue away from the drainage area so fluid can move out more freely. The goal is to reduce the risk of angle closure and help keep pressure steadier in eyes with a narrow angle. During treatment, a special lens sits on the eye while laser spots reshape the peripheral iris area without cutting. Follow-up visits focus on angle width and pressure behavior, since some angles can narrow again with time.

Frequently Asked Questions

Can gonioplasty replace other glaucoma treatments?

It helps certain angle-based problems but does not replace all options. Doctors decide based on structure and pressure patterns. Exams guide selection. Plans differ by case.

How long does gonioplasty last?

Results vary; some people experience long-term angle improvement. Doctors review changes over time. Imaging shows tissue stability. Follow-up is ongoing.

Does gonioplasty hurt?

Most people feel only mild pressure during the procedure. Doctors use numbing drops. Recovery is usually quick. Comfort returns shortly after.

Can the angle narrow again after gonioplasty?

It can, especially if tissue crowding continues with age. Doctors track structure at visits. Imaging reveals early shifts. Care adjusts with changes.
