Several types of glaucoma can be treated with laser surgery, depending on the specific characteristics of the condition and the individual's response to other treatments. The types of glaucoma that are commonly treated with laser surgery include:
Open-Angle Glaucoma: This is the most common type of glaucoma, characterized by increased intraocular pressure (IOP) due to the slow drainage of aqueous humour from the eye's drainage angle. Laser trabeculoplasty, such as selective laser trabeculoplasty (SLT) or argon laser trabeculoplasty (ALT), can be used to improve drainage and lower IOP.
Angle-Closure Glaucoma (Narrow-Angle or Closed-Angle): In angle-closure glaucoma, the drainage angle of the eye becomes blocked or narrowed, leading to a rapid increase in IOP. Laser peripheral iridotomy (LPI) is a common procedure used to create a small hole in the iris, allowing fluid to flow freely and relieve the angle closure.
Secondary Glaucomas: These are glaucomas that occur as a result of other eye conditions or systemic diseases. Laser surgery may be used as part of the treatment for certain secondary glaucomas, such as neovascular glaucoma or pigmentary glaucoma.
Progressive Glaucomas: In some cases, laser surgery may be recommended for progressive glaucomas that are not adequately controlled with medications or other treatments. This may include repeat laser treatments or combined procedures.
It's important to note that the suitability of laser surgery for treating glaucoma depends on factors such as the type and severity of glaucoma, the presence of other eye conditions, and the individual's overall eye health. A comprehensive eye examination and consultation with an ophthalmologist are necessary to determine the most appropriate treatment approach for each person with glaucoma.
