How does posterior vitreous detachment affect vision?

When your vitreous detaches, strands of the vitreous often cast new shadows on your retina — and those shadows appear as floaters. You may also notice flashes of light in your side (peripheral) vision. Sometimes, vitreous detachment causes more serious eye problems that need treatment right away.

Can retinal detachment happen in both eyes at the same time?

Exudative (serous) retinal detachment is rare. It happens when fluid collects under your retina, but there’s no tear. It can affect both eyes. This type of detachment is often comes from an eye injury or as a complication of a wide range of diseases.

Why would a retinal detachment cause a loss of vision?

Rhegmatogenous detachments are caused by a hole or tear in the retina that allows fluid to pass through and collect underneath the retina, pulling the retina away from underlying tissues. The areas where the retina detaches lose their blood supply and stop working, causing you to lose vision.

Does vitreous detachment cause blurred vision?

In the majority of cases, PVD does not result in any side effects aside from flashes and floaters. In rare instances, patients report that their overall vision is distorted. The patient may experience blurry vision, partial loss of vision, tunnel vision, or sensitivity to light.

How common is bilateral retinal detachment?

Simultaneous bilateral RRD, more specifically, has an annual incidence of 0.35 patients per 100,000 individuals, and is more likely to occur in young, highly myopic, male patients with multiple round atrophic retinal holes (4,5).

What is the difference between posterior vitreous detachment and retinal detachment?

Posterior vitreous detachment is seen as a freely mobile hyperechoic membrane that swirls away from the optic disc with movement of the eye. This finding differs from a retinal detachment in that it “crosses the midline,” with the optic disc representing the midline (Figure 4).

Can retinal detachment cause death?

When the retina becomes detached from the wall of the eye, it is separated from its normal position and can suffer from a loss of blood flow leading to tissue death.
