Retinal detachment can occur as a result of: - Shrinkage or
contraction of the vitreous (VIT-ree-us) — the gel-like material
that fills the inside of your eye. This can create tugging on
the retina and a retinal tear, leading to a retinal detachment.
- Advanced diabetes - An inflammatory eye disorder How retinal
detachment occurs Retinal detachment can occur when the gel-like
material (vitreous) leaks through a retinal hole or tear and
collects underneath the retina. Reasons for holes or tears
include: Aging or retinal disorders can cause the retina to
thin. Retinal detachment due to a tear in the retina typically
develops when there is a sudden collapse of the vitreous,
causing tugging on the retina with enough force to create a
tear. Fluid inside the vitreous then finds its way through the
tear and collects under the retina, peeling it away from the
underlying tissues. These tissues contain a layer of blood
vessels called the choroid (KOR-oid)
