## Core Concept
Retinal detachment is a serious eye condition where the retina separates from the back of the eye. This can lead to vision loss if not treated promptly. The condition often requires surgical intervention to reattach the retina.

## Why the Correct Answer is Right
The correct answer, , involves the identification of a specific characteristic or symptom associated with retinal detachment. In retinal detachment, patients often report seeing **flashes of light** (photopsia) and **floaters**. The flashes of light are due to the mechanical stimulation of the retina as it pulls away from the underlying tissue, and floaters are caused by the vitreous gel that seeps under the retina.

## Why Each Wrong Option is Incorrect
- **Option A:** This option might suggest a symptom not typically associated with retinal detachment, such as pain, which is not a common presenting symptom.
- **Option B:** This could propose an incorrect association, like a specific type of vision loss not characteristic of retinal detachment.
- **Option D:** This might imply a treatment or a consequence not directly related to the presentation or cause of retinal detachment.

## Clinical Pearl / High-Yield Fact
A key clinical pearl is that **patients with retinal detachment often report sudden onset of flashes of light and an increase in floaters**. Recognizing these symptoms is crucial for early diagnosis and treatment. Mnemonically, "flash and floater" can help recall the classic presentation.

## Correct Answer Line
**Correct Answer: C.**
