Most of the patients suffering from glaucoma do not experience any symptoms or pain. They usually occur very slowly and is not targeted over a particular age group.
Causes of glaucoma:
- Build up of aqueous humour due to blockage of mesh like drainage channels. This results in elevated intraocular pressure. The reason for blockage is still not known.
- Other causes include blunt injury, chemical injuries, severe infections, blocked blood vessels and the such.
Glaucoma usually affects both eyes, but it may be worse in one eye.
Most common types of glaucoma:
- Open-angle glaucoma: It is cause by slow clogging of drainage canals, resulting in increased eye pressure. Characterized by the presence of wide and open angle between iris and cornea. It develops slowly and is a lifelong condition. It's symptoms usually go unnoticed.
- Angle-closure glaucoma: Caused by blocked drainage canals resulting in sudden elevation of intraocular pressure. Symptoms of this type of glaucoma are very noticeable and requires immediate medical attention.
- Normal Tension Glaucoma: In this case, the nerves get damaged even though the intraocular pressure is normal.
- Congenital glaucoma: This type of glaucoma occurs in babies where the drainage canals are poorly developed.
