Glaucoma arises when your intra-ocular fluid doesn’t drain properly. When this happens your eye pressure also raises – also called intra-ocular pressure (IOP). This process damages the nerve fibres inside the optic nerve which causes permanent damage to your vision.
It’s important to remember that there are different types of Glaucoma, thus the presentation may vary. Many types of glaucoma have no warning signs. The effect is so gradual that you may not notice a change in vision until the condition is at an advanced stage.
When the pressure inside the eye rises to severe levels you may experience symptoms like sudden eye pain, headaches, blurred vision and the appearance of halos around lights.
Glaucoma is, unfortunately, an irreversible disease; the goal of the treatment is to prevent any further vision loss. Luckily, if detected early glaucoma can be managed and with medical/surgical treatment most patients will not lose their sight.
