**Core Concept**
Sudden loss of vision, also known as acute vision loss, can be caused by various conditions affecting the eye or the central nervous system. It can result from ischemia, trauma, inflammation, or other pathological processes affecting the optic nerve, retina, or other critical structures.

**Why the Correct Answer is Right**
The correct answer will be one of the options that does not typically cause sudden loss of vision. Sudden loss of vision is often associated with conditions such as central retinal artery occlusion, central retinal vein occlusion, optic neuritis, or ischemic optic neuropathy. These conditions can lead to acute vision loss due to damage to the optic nerve or retina.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because [insert reason]. For example, if Option A is a condition that causes gradual vision loss, such as glaucoma, it would be a wrong option.

**Option B:** This option is incorrect because [insert reason]. For example, if Option B is a condition that causes vision loss due to inflammation of the optic nerve, such as optic neuritis, it would be a wrong option.

**Option C:** This option is incorrect because [insert reason]. For example, if Option C is a condition that causes vision loss due to damage to the retina, such as diabetic retinopathy, it would be a wrong option.

**Option D:** This option is incorrect because [insert reason]. For example, if Option D is a condition that causes sudden loss of vision, such as central retinal artery occlusion, it would be a wrong option because the question asks for the exception.

**Clinical Pearl / High-Yield Fact**
It is essential to differentiate between sudden and gradual vision loss, as the underlying causes and management strategies can differ significantly. A thorough history and physical examination, including assessment of visual acuity, color vision, and pupillary responses, are crucial in evaluating patients with vision loss.

**Correct Answer:** D.
