All of the following are the causes of exudative retinal detachment except:
**Core Concept**
Exudative retinal detachment occurs when fluid accumulates under the retina without any breaks or tears in the retina itself. This condition is often associated with underlying systemic or ocular diseases that lead to the abnormal accumulation of fluid.
**Why the Correct Answer is Right**
Exudative retinal detachment is typically caused by conditions that lead to the leakage of fluid from blood vessels, such as tumors, inflammation, or vascular diseases. For example, in diabetic retinopathy, the leakage of fluid from the blood vessels can cause the retina to detach. Another example is uveitis, an inflammatory condition that can lead to the leakage of fluid and subsequent retinal detachment.
**Why Each Wrong Option is Incorrect**
**Option A:** Tractional retinal detachment is a type of retinal detachment caused by fibrovascular proliferation and scarring, which is a different mechanism from exudative retinal detachment. Therefore, it is not a cause of exudative retinal detachment.
**Option B:** Rhegmatogenous retinal detachment is the most common type of retinal detachment, caused by a tear or hole in the retina that allows fluid to enter and cause the retina to detach. This is not a cause of exudative retinal detachment.
**Option C:** Retinal dialysis is a type of retinal detachment that occurs when there is a tear in the retina, but it is not a cause of exudative retinal detachment.
**Clinical Pearl / High-Yield Fact**
Remember that exudative retinal detachment is often associated with underlying systemic or ocular diseases, and a thorough evaluation of these conditions is necessary to determine the cause of the detachment.
**Correct Answer:** D.
