Causes of Glaucoma
Glaucoma can occur because of many factors. One of them is intraocular pressure. Your eyes produces fluid called aqueous humor which nourishes the eye. This fluid leaves your eye after nourishing it through a drainage canal between your Iris and cornea.
With glaucoma, these fluids aren’t able to leave the eye due to restrictions in your drainage canals, so the fluid builds up in your eye and this, eventually,, the pressure in your eye and damages the optic nerve, leading to glaucoma.
Risk Factors for glaucoma are
1. Diabetes
2. High blood pressure
3. Aging
4. Eye injury
5. Myopia
Many people with glaucoma do not experience any warning signs. The effect is so gradual that you may not notice any change in your vision during the course of the condition until it gets to its later stage. That’s why it’s necessary to go for a regular eye check, including measurement of the pressure in your eye.
If glaucoma is recognized early, vision loss can be prevented or delayed. People with glaucoma may need to be on treatment for the rest of their lives.
