Non Inflammatory edema of optic disc due to raised intracranial pressure is called –
**Core Concept**
Non-inflammatory edema of the optic disc, caused by increased intracranial pressure, is a condition where the optic disc swells due to the compression of the optic nerve. This occurs when the pressure within the cranial cavity rises, compressing the optic nerve and leading to fluid accumulation in the optic disc.
**Why the Correct Answer is Right**
The correct answer is related to the concept of papilledema, which is a condition characterized by swelling of the optic disc due to increased intracranial pressure. This swelling is caused by the compression of the optic nerve, leading to the accumulation of fluid in the optic disc. The increased pressure within the cranial cavity compresses the optic nerve, disrupting its normal function and leading to the characteristic swelling of the optic disc.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect as it does not relate to the specific condition of non-inflammatory edema of the optic disc due to raised intracranial pressure.
* **Option B:** This option is incorrect as it refers to a different condition, which is not related to the swelling of the optic disc due to increased intracranial pressure.
* **Option D:** This option is incorrect as it refers to a condition that is not directly related to the optic disc or increased intracranial pressure.
**Clinical Pearl / High-Yield Fact**
Papilledema is a clinical sign that can be used to diagnose increased intracranial pressure. It is essential to note that papilledema is a non-specific sign and can be caused by various conditions, including tumors, hemorrhages, and infections.
**Correct Answer:**
Pseudopapilledema is not the correct term here, the correct term is actually **Papilledema**
