Glaucoma

Treatment of Glaucoma

Glaucoma is a disease caused by build-up of eye pressure, which results in damage of the fibers forming the optic nerve. The optic nerve carries the visual information from the eye to the brain. Therefore, any damage to it causes deterioration in vision which can even progress to blindness if timely treatment is not given. A healthy eye is known to have a pressure in the range of 10-21 mmHg (like a balloon filled with water). A fluid called the aqueous humor is continuously formed and drained in the eye throughout one's life, creating and maintaining this pressure. This silent disease is very serious but the patients rarely feel any symptoms. By the time the problem is reported, in most cases, the damage is irreversible. Glaucoma cases are generally spotted during a routine eye examination by an eye doctor. The disease can be controlled if detected at an early stage. The cure of glaucoma involves keeping the eye pressure within normal range and stopping its further deterioration by means of eye drops, laser or surgery.

What are the types of glaucoma?
  • Open Angle Glaucoma
  • Narrow Angle Glaucoma
  • Secondary Glaucoma
  • Congenital Glaucoma

What is the difference between cataract (safed motia) and glaucoma (kala motia)?

Cataract is due to opacity in the lens of the eye which prevents the image to properly focus on the retina. Glaucoma is caused due to rise in eye pressure which damages the optic nerve fibers. Loss of vision due to cataract is recovered by surgery ( phacoemulsification with intraocular lens implantation), while visual loss in glaucoma is permanent if not treated at an early stage. Sometimes, both cataract and glaucoma may be present together. Common causes of glaucoma are as under:

  • Diabetics
  • Spectacle wearers- Myopia/ Hypermetropia
  • Steroid users
  • Family history of glaucoma
  • Thyroid diseases
  • Other eye diseases eg. uveitis, vitreous hemorrhage, major eye surgery etc.
  • Eye injury
