The retina converts light wavelength energy into vision. An unhealthy retina bodes poorly for long term good vision.
What are the symptoms of a Retinal Detachment, Retinal hole, Retinal Tear ?
Retinal Detachment, Retinal hole, Retinal Tear are eye emergencies are require immediate evaluation by Dr. Duplessie.
The appearance of floaters can be very alarming. They are shadows from debris floating inside the vitreous.
2) Lightning Flashes:
Lightning flashes are from the vitreous tugging on the retina. The retina is stimulated by tension which results in light flashes. Flashes can be an indication of a retinal detachment
3) Decreased Vision:
Can occur secondary to bleeding inside the eye or retinal detachment. Early on, central vision may be normal but slowly some patients note a progressive “curtain, veil, or fog” which may obscure peripheral then central vision. If you are seeing an expanding veil/cloud in your eye you need to be seen immediately.
Posterior Vitreous Detachment (PVD) a cause of Retinal Detachment, Retinal hole, Retinal Tear
Most people will have a posterior vitreous detachment. It commonly happens in healthy eyes.
Additional events, which may lead to a PVD include
1) a history of eye surgery,
4) injury to the eye, and
5) bleeding inside the eye.
Do all Posterior Vitreous Detachments lead to a retinal detachment ?
For the majority of those who have a PVD, there is no danger involved.
Up to 15% of those with a symptomatic PVD have an associated retinal tear.
Up to 50% of patients with one or more risk factors and a symptomatic PVD will develop a retinal tear.
A retinal tear can lead to a retinal detachment.
The diagnosis of a retinal tear or detachment is only made with a dilated retinal examination.
Retinal Detachment, Retinal hole, Retinal Tear
A retina detachment is a surgical emergency in most cases.
