Retinal detachment is not seen in –
**Core Concept**
Retinal detachment occurs when the retina separates from the underlying retinal pigment epithelium, leading to vision loss. This condition is often associated with aging, trauma, and underlying retinal diseases such as retinal tears, lattice degeneration, or epiretinal membrane.
**Why the Correct Answer is Right**
The correct answer is related to the pathophysiology of retinal detachment. It is not typically seen in conditions where the vitreous gel remains attached to the retina. **Option C**, vitreomacular adhesion (VMA), is a condition where the vitreous gel is attached to the retina, but not fully detached. This condition can cause symptoms such as blurred vision and metamorphopsia, but it does not lead to retinal detachment.
**Why Each Wrong Option is Incorrect**
* **Option A:** is incorrect because retinal detachment can occur in patients with high myopia, where the retina is stretched and thinned, making it more susceptible to tears and detachment.
* **Option B:** is incorrect because retinal detachment can occur in patients with diabetic retinopathy, where the retinal blood vessels are damaged, leading to retinal ischemia and neovascularization.
* **Option D:** is incorrect because retinal detachment can occur in patients with trauma to the eye, where the retina is directly injured, leading to tears or detachment.
**Clinical Pearl / High-Yield Fact**
It is essential to note that retinal detachment is a medical emergency that requires prompt treatment to prevent permanent vision loss.
**Correct Answer: C. Vitreomacular adhesion (VMA).**
