Whereas cataracts is a natural normally age related condition glaucoma is caused by the damage to the optic nerve. Open-angle glaucoma is the most common type of glaucoma with a slower rate of vision loss. Open-angle glaucoma is caused by clogging of drainage canals which increases eye pressure. There is a wide open angle in between the cornea and the iris and is slow to develop. The wide open angle between the iris and cornea gives the name open-angle glaucoma. Open-angle glaucoma generally goes unnoticed. The effects of this glaucoma are gradual and have no noticeable symptoms. Angle-closure glaucoma is also called narrow-angle glaucoma and is less common and caused by drainage canals that are blocked. With angle-closure glaucoma the intraocular pressure experiences a sudden increase and has a closed angle between the cornea and iris. Angle-closure is quick developing and is very noticeable compared to open-angle glaucoma that goes fairly unnoticed. Angle-closure glaucoma will need medical attention soon. Some signs of angle-closure glaucoma include nausea, pain, headache, and blurry
