**Core Concept**
Retinal detachment is a medical emergency characterized by the separation of the retina from the underlying retinal pigment epithelium (RPE), leading to vision loss if not promptly treated. Early detection and management are crucial to prevent irreversible damage.

**Why the Correct Answer is Right**
In early retinal detachment, patients may experience a sudden onset of photopsia (flashing lights), floaters, and a decrease in visual acuity, often with a scotoma or a blind spot in the visual field. These symptoms occur due to the mechanical disruption of photoreceptor function and the subsequent release of photoreceptor outer segments into the vitreous humor.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as it is a characteristic feature of early retinal detachment. The sudden onset of photopsia is a hallmark symptom of retinal detachment, often preceding other visual disturbances.
**Option B:** This option is incorrect as it is a common finding in advanced retinal detachment, where the retina has fully separated from the RPE, leading to significant vision loss.
**Option C:** This option is incorrect as it is more commonly associated with conditions such as posterior vitreous detachment (PVD) or diabetic retinopathy, rather than early retinal detachment.

**Clinical Pearl / High-Yield Fact**
A classic mnemonic to remember the symptoms of retinal detachment is "F.A.D.E.": Flashing lights, Floaters, Decreased vision, and Enlarging blind spot.
