How is Glaucoma Treated?

The main goal of all types of glaucoma treatment is to lower the intraocular pressure (IOP). This can be achieved using one or a combination of eye drops, SLT(selective laser trabeculoplasty), or in more advanced cases a combination of the two or glaucoma surgery. Laser iridotomy is usually necessary to treat narrow angle glaucoma in addition to eye drops.

  • Eye drops are used once to three times daily. They lower the eye pressures by decreasing the fluid (aqueous) production, increasing the outflow from the eye, or both.
  • SLT is used to treat open angle glaucoma. It is a low-energy laser treatment to create a slight inflammation to open the drainage channels. SLT’s success is about 80-85%. 
  • Laser iridotomy is used to treat the narrow angle type of glaucoma. By creating a small permanent opening in the iris (the color membrane part of the eye), fluid can drain through it rather than through the pupil when the narrow angle occlusion happens.
