As per norms I should answer for first 4 questions only
1) Cataracts are a very common eye condition. As we get older the lens inside our eye gradually changes and becomes less transparent (clear). A lens that has turned misty, or cloudy, is said to have a cataract. Over time a cataract can get worse, gradually making your vision mistier.
Cataracts in the eye grows slowly and causes gradual loss of vision.
2) Cataracts can be caused by a number of things, but by far the most common reason is growing older. Most people over the age of 65 have some changes in their lens and most of us will develop a cataract in time. Apart from getting older, the other common causes of cataract include:
3) Glaucoma has many different variants but when it is simply referred to as "glaucoma" it normally means the following: the pressure inside the eye (IOP or intraocular pressure) is too high for that eye (whether it is high or low is immaterial) and as a result there is damage to the optic nerve that leads to visual field loss.
4)the visual disease of Macular degeneration affects many elderly people, causing a loss of central vision.
The most common causes of vision loss among the elderly are age-related macular degeneration, glaucoma, cataract and diabetic retinopathy. Age-related macular degeneration is characterized by the loss of central vision.
