Not a risk factor of rhegmatogenous retinal detachment: March 2011
**Core Concept**
Rhegmatogenous retinal detachment is a condition where the retina separates from the underlying tissue due to a tear or hole in the retina. It is a type of retinal detachment that occurs due to the vitreous gel pulling on the retina, causing it to detach from the underlying retinal pigment epithelium.
**Why the Correct Answer is Right**
Rhegmatogenous retinal detachment is primarily caused by a tear or hole in the retina, which allows fluid to seep under the retina and cause it to detach. This type of detachment is often associated with aging, myopia, and trauma to the eye. The correct answer is related to a condition that is not a risk factor for rhegmatogenous retinal detachment.
**Why Each Wrong Option is Incorrect**
* **Option A:** Age-related macular degeneration is a risk factor for rhegmatogenous retinal detachment, as it can cause the retina to become thin and more susceptible to tears.
* **Option B:** Myopia is a well-known risk factor for rhegmatogenous retinal detachment, as it can cause the retina to stretch and become more susceptible to tears.
* **Option C:** Trauma to the eye is a risk factor for rhegmatogenous retinal detachment, as it can cause a tear or hole in the retina.
**Clinical Pearl / High-Yield Fact**
It's essential to remember that rhegmatogenous retinal detachment is a medical emergency that requires prompt treatment to prevent vision loss. Early detection and treatment can significantly improve outcomes, making it crucial for patients to undergo regular eye exams, especially if they have a history of myopia or trauma to the eye.
**Correct Answer:** D.
