A watery fluid known as aqueous humor fills the spaces in the front one-third area of the eye. The aqueous humor is continually produced by the ciliary body and drained through channels located in the trabecular spaces of the angle of the eye at a balanced rate. With advancing age, these channels get blocked.
disrupting the outflow of this fluid and resulting in raised pressure within the eye. This raised pressure then starts damaging the optic nerve leading to decreased field of vision. This condition is Called GLAUCOMA or KALA MOTIA.
