Stroke Warning: Retinal Artery Blockage!

Retinal Artery Blockage May Warn of Impending Stroke A certain retinal vessel disease may be a warning of an impending stroke! When an artery or vein in the retina becomes blocked or “occluded” it can be a sign of more serious health issues that need to be looked-quickly! A central retinal artery occlusion (CRAO) is a disease of the eye where the flow of blood through the central retinal artery is blocked. Patients suffering from a central artery occlusion experience a sudden, severe, painless loss of vision in one eye. While there can be several different causes of the blockage, most often a central retinal artery occlusion is caused by unhealthy carotid arteries which supply the head and neck with oxygen.

Flashes & Floaters Need Attention

If you experience flashes or light or suddenly start seeing floaters, it’s best not to ignore these events, but rather to quickly schedule an appointment to see us, as although most of the time flashes and floaters are benign, sometimes they can be a sign of a sight threatening problem.

If you have no experienced any trauma to your eye or head, it is often the case that flashes and floaters are due to a Posterior Vitreous Detachment (PVD). PVD is a very common eye condition. It's caused by natural changes to the vitreous gel which takes up the space inside the eye. Although PVD causes some frustrating symptoms it doesn’t cause pain, harm the eye or cause permanent loss of vision. Sometimes, a PVD can either be accompanied by or a warning sign of retinal tears which can lead to retinal detachment and vision loss. Retinal detachment must be diagnosed and repaired quickly.

If you experience a sudden onset of flashes and floaters please call us immediately and schedule an appointment so we can examine the vitreous and retina and be sure there are no tears or risks of retinal detachment.
