Flashing Lights or a sudden increase in floaters may be a precursor to a retinal detachment

As we mature, 50% of individuals may experience the sudden onset of flashing lights or new floaters. This often signfies a posterior vitreous detachment. People with higher degrees of near-sightedness are more likely to experience a posterior vitreal detachment. The vitreous is a jelly filled sac inside the eye that has attachments to the optic nerve and peripheral retina. The vitreous jelly in our eyes condenses as we mature. As it does so, it may cause traction on your retina that is perceived as a flashing light. For some, this traction results in a tear in the retina. Fluid may get under the tear, resulting in a retinal detachment.

To reduce your risk of severe vision loss, it is recommended that you be seen as soon as possible (within 24 to 48 hours) of the onset of these symptoms. However, if you cover one eye and notice that part of the world is missing or shaded in a dark curtain, it is likely that a retinal detachment has occurred.

Repairing a retinal detachment before your central vision is affected will reduce the risk of severe vision loss. Small retinal tears may be treated with a laser to create a scar to prevent fluid from getting under the retina and causing a retinal detachment.

If you develop these symptoms, you should call Dr. Thompson to schedule an appointment or be seen by your local eye care professional as soon as possible.
