Glaucoma is an eye disease arising from

Options

A. Intra-arterial pressure
B. Intraocular pressure
C. Intraventricular pressure
D. Intravesicular pressure.

Answer

**Step-by-Step Solution:**

1. **Understanding Glaucoma**: Glaucoma is an eye disease that affects vision and can lead to blindness if not treated. It is primarily related to the pressure inside the eye.

2. **Identifying the Cause**: The disease is caused by the blockage of tiny ducts that are responsible for draining excess aqueous humor, which is the fluid in the eye.

3. **Consequences of Blockage**: When these ducts are blocked, the aqueous humor cannot drain properly, leading to a buildup of this fluid within the eye.

4. **Increase in Intraocular Pressure**: The accumulation of aqueous humor results in an increase in intraocular pressure (IOP). This pressure is crucial because it can affect the overall health of the eye.

5. **Impact on Nerve Fibers**: The elevated intraocular pressure can compress the optic nerve and other structures in the eye, leading to damage and death of nerve fibers.

6. **Resulting Vision Loss**: The damage to the optic nerve fibers can result in partial blindness or vision loss, which is a significant concern for individuals with glaucoma.

7. **Final Answer**: Therefore, glaucoma is an eye disease arising from increased intraocular pressure.

**Final Answer**: Glaucoma is an eye disease arising from intraocular pressure.
