All satements are true about papilloedema except –
**Core Concept**
Papilloedema is a condition characterized by swelling of the optic disc due to increased intracranial pressure, which can be caused by various conditions such as brain tumors, hydrocephalus, or cerebral edema. The swelling leads to impaired venous outflow from the optic disc, resulting in optic disc edema.
**Why the Correct Answer is Right**
The correct answer should accurately describe a characteristic of papilloedema. The condition is often associated with signs such as blurred vision, transient visual obscurations, and impaired color vision. These symptoms occur due to the compression of the optic nerve and impaired axoplasmic flow.
**Why Each Wrong Option is Incorrect**
**Option A:** Papilloedema is a unilateral condition. This statement is incorrect because papilloedema is typically a bilateral condition, affecting both optic discs.
**Option B:** Papilloedema is caused by increased intracranial pressure. This statement is correct, but we are looking for the exception, so let's evaluate the remaining options.
**Option C:** Papilloedema is a condition that resolves on its own. This statement is incorrect because papilloedema is often a sign of an underlying condition that requires treatment, and the optic disc edema may persist until the underlying condition is addressed.
**Option D:** Papilloedema is associated with optic atrophy. This statement is incorrect because papilloedema is a condition that can precede optic atrophy, but the two are not synonymous.
**Clinical Pearl / High-Yield Fact**
Papilloedema is a condition that requires prompt evaluation and treatment of the underlying cause, as the optic disc edema can lead to permanent visual impairment if left untreated.
**Correct Answer: A. Papilloedema is a unilateral condition.**
