Glaucoma

About- Glaucoma is a group of eye conditions that damage the optic nerve (connects the eye to the brain) and can cause blindness.
 
Types of
Glaucoma and causes-
Glaucoma Open-Angle Glaucoma- In this case, the trabecular meshwork is partially blocked, and that causes pressure in the eye and damages the optic nerve.
Glaucoma Angle-Closure Glaucoma- It occurs when the iris bulges forward to narrow or block the drainage angle formed by the cornea and iris. Due to that, fluid can't circulate through the eye, and pressure increases.
Glaucoma Glaucoma in children- It may be present from birth or develop in the first few years of life. 
Glaucoma Pigmentary Glaucoma- Pigment granules from the iris build up in the drainage channels, slowing or blocking fluid exiting the eye
Glaucoma Normal-Tension Glaucoma- The exact reason is not clearly understood, the optic nerve becomes damaged even though the eye pressure is within the normal range.
