Welcome to question of the day #50

What are the key steps in the development of rhegmatogenous retinal detachment?

The vitreous humor is a hydrated gel whose structure is maintained by a collagenous and mucopolysaccharide matrix.

As people age, this macromolecular network begins to liquefy and collapse.

The vitreous shrinks, and vitreo-retinal traction develops.

Eventually, the vitreous partly separates from the retinal surface which is known as posterior vitreous detachment.

In 10-15% of patients with symptomatic posterior vitreous detachment, a retinal flap, tear or hole forms as the vitreous pulls away from the retina.

Rhegmatogenous detachment occurs when liquid vitreous enters the subretinal space through a retinal break.

This creates a plane of dissection between the retina and retinal pigment epithelium.

Over time, the area of detachment increases as more fluid passes through the retinal break.
