Question

What causes hardening of the eyeball and great pressure inside the eye?
A. Cataract
B. Trachoma
C. Glaucoma
D. Meningitis

Answer 1

Hint: High pressure in the eyes is caused by the imbalance and drainage of the fluid in the eye. The channels which normally drain the fluid by the eye don't work properly. High pressure in the eyes may result in optic neuritis or grave disease. Eye pressure is higher than the eye feels. Touching the eyeball by the eyelid is called tactile pressure. Sinus is also the reason for getting pressure in the eyes. It is the external source for getting pressure in eyes.

Complete answer:
Option A: Normal clouding on the clear lens of the eye is caused by the cataract. It will develop more as the years go by. It is caused because of aging and injuries in the tissue which makes the eye lens. Genetic disorder may also cause the cataract. Eye surgery and the diabetes condition also cause the cataract.
Option A is the incorrect
Option B: Trachoma is the bacterial infection which attacks the eye. It is the main reason for getting blind. It affects both eyes. It will cause eye pain and also blurred vision. Chlamydia trachomatis is the bacteria which causes trachoma. It roughens the inner surface of the eyelids.
Option B is the incorrect
Option C: Because of the high pressure the vision and brain also are damaged. Open angle glaucoma and angle closure glaucoma are the two types of glaucoma. Blocked blood vessels and the high pressure will cause glaucoma. So the eye will be hardened. Optic nerve damage will cause glaucoma.
Option C is the correct
Option D: Inflammation in the brain and spinal cordial causes meningitis. It is the viral infection and also the fungi and bacteria. Some forms of vaccine may avoid some types of meningitis. Bacteria travel the blood and attack the brain or it directly attacks the meninges.
Option D is the incorrect

Option C is the correct answer.

Note:
Intraocular pressure is the reason for glaucoma. It damages the optic nerve. The Optic nerve sends the image to the eye from the brain. Above forty age easily gets the glaucoma. It will come family by family. Cyclophotocoagulation treatment occurs at the middle layer of the eyes to lower the fluid level. Iridotomy is the process of putting a small hole in the eye to make the easy flow of fluid in the eyes. It is a lifelong disease. Once we get this then we can't overcome it.
