Did you know that glaucoma can lead to you losing as much as 40% of your vision, without you even realising you had glaucoma? That’s why this condition is called the ‘sneak thief of sight’. What exactly is glaucoma, and how can you prevent it?
What is glaucoma?
Glaucoma is not one but a family of eye conditions – there are about 30 different types – that affect pressure within the eye and damage the optic nerve. This leads to pain and blurred vision. Glaucoma is one of the leading causes of blindness worldwide and the especially scary aspect of this condition is that you probably won’t notice any symptoms until it’s too late and your vision is already severely damaged. Permanent vision loss follows.
The most common types are open angle glaucoma and closed angle glaucoma.
Open angle glaucoma
This is the form that has earned the title ‘sneak thief of sight’ because it creeps up on you. You feel no pain or symptoms, but you gradually see less and less and eventually develop tunnel vision (when it feels like you are looking through a tunnel) and even blindness. Open angle glaucoma affects 90% of diagnosed patients.
