Question

In which of the following conditions does intraocular pressure increase?
1. conjunctivitis
2. glaucoma
3. cataracts
4. retinitis

Answer 1

Correct Answer - Option 2 : glaucoma

Concept:

• Glaucoma is a degeneration of the optic nerve.
• It has increased intraocular pressure (IOP).
• The normal IOP is 12-22 mm Hg.
• A glaucoma is a group of eye conditions that damage the optic nerve, the health of which is vital for good vision.
• With all types of glaucoma, the nerve connecting the eye to the brain is damaged, usually due to high eye pressure.
• The most common type of glaucoma (open-angle glaucoma) often has no symptoms other than slow vision loss. Angle-closure glaucoma, although rare, is a medical emergency and its symptoms include eye pain with nausea and sudden visual disturbance.
• Glaucoma is one of the leading causes of blindness for people over the age of 60.
