A patient presents with sudden onset of floaters and 'flashes of light' in the right eye, followed by a dark curtain moving across the visual field. Fundus examination reveals a superior retinal detachment with a horseshoe tear. What is the fundamental mechanism of this type of retinal detachment?
- A.Accumulation of exudate beneath the sensory retina due to choroidal tumors
- B.Traction on the sensory retina by proliferating fibrovascular membranes
- C.Liquefaction of the vitreous leading to fluid entry into the subretinal space through a retinal breakCorrect answer
- D.Inflammation of the retinal pigment epithelium causing breakdown of the blood-retinal barrier
Solution
The scenario describes a rhegmatogenous retinal detachment, which occurs when a break (tear, hole, or dialysis) forms in the retina, allowing liquefied vitreous humor to pass through the break and accumulate in the potential space between the sensory retina and the retinal pigment epithelium.
