Glaucoma – The silent thief of vision

Glaucoma is caused by a build-up of pressure inside the eyes. It is generally an inherited disease and strikes in later life. The increased pressure damages the optic nerve resulting in loss of vision. The vision loss is generally very gradual and may not be noticed early because the loss of vision progresses from outside towards the centre. The loss of vision is irreversible. The sooner it is detected and controlled the better will be vision retention. Glaucoma can only be detected through a comprehensive eye examination. Periodic eye checks are vital especially if there is a family history.

How Is Glaucoma Treated?

  • Glaucoma treatment may include prescription eye drops, laser, or microsurgery. the treatment of choice varies with the type of glaucoma.
  • Eye drops for glaucoma. These either reduce the formation of fluid in the front of the eye or increase its outflow. Thereby reducing the pressure inside the eye Laser surgery for glaucoma.
  • Laser surgery for Glaucoma slightly increases the outflow of the fluid from the eye in open-angle Glaucoma or eliminates fluid blockage in angle-closure glaucoma.
  • Microsurgery for glaucoma. In an operation called a trabeculectomy, a new channel is created to drain the fluid, thereby reducing intraocular pressure that causes glaucoma.

Glaucoma Treatment

  • Medical management
  • YAG Laser iridotomy
  • Trabeculectomy
  • Trabeculectomy with Trabeculotomy for paediatric glaucoma
  • Valve implantation
  • Cyclo-cryo procedure for refractive glaucoma

Glaucoma is detected through a comprehensive eye exam that includes:

Visual acuity test. This eye chart test measures how well you see at various distances. Tonometry. An instrument measures the pressure inside the eye. Numbing drops may be applied to your eye for this test. Visual field test. This test measures your side (peripheral) vision. It helps your eye care professional tell if you have lost side vision, a sign of glaucoma. Dilated eye exam. Drops are placed in your eyes to widen, or dilate, the pupils.
