Question

What causes shifting fluid ?

• A. Exudative Retinal detachment
• B. Tractional Retinal Detachment
• C. Rhegmatogenous retinal detachment
• D. Retinodialysis

Answer 1

The Correct Option is A

In dermatology, understanding the causes of shifting fluid in relation to retinal detachments is crucial. Here we explore the different types mentioned and identify the correct cause:

• Exudative Retinal Detachment: This type of retinal detachment is caused by fluid accumulating beneath the retina due to inflammation, a tumor, or vascular abnormalities. The fluid can shift with changes in body position, leading to a shifting fluid phenomenon.
• Tractional Retinal Detachment: In this case, fibrovascular tissue pulls on the retina, causing detachment. No fluid shifting is typically associated with this mechanism.
• Rhegmatogenous Retinal Detachment: A tear or break in the retina allows fluid to seep underneath, detaching it. The fluid here is not due to shifting and rather requires a retinal tear.
• Retinodialysis: An anterior retinal break at the ora serrata, leading to detachment, but it does not cause shifting fluid on its own.

Based on the explanations, the cause of shifting fluid is Exudative Retinal Detachment due to its association with fluid accumulation and movement. This condition occurs independently of any tears or traction forces.
