What is it?

The retina plays an important role in providing us our vision. Sometimes we can have a retinal detachment which results in the retina pulling away from its normal position resulting in vision loss. It is also possible to have retinal holes and tears which results in a break in the retina and the accumulation of fluid resulting in a detachment occurring. This can result in someone having symptoms of blurred vision, flashes of light, a curtain veil blocking some of their vision and floaters covering their vision.

Who is at risk and how do you treat it?

Individuals who have had previous eye surgeries, high nearsightedness, or trauma to the eye or head will also increase the chance of a retinal detachment occurring. Age also plays a factor in this as the vitreous gel found in our eye shrinks overtime and can pull away from the retina resulting in a possible hole or tear. Yearly dilated eye exams are done to help detect and prevent retinal detachments from occurring. It is especially important that you see an optometrist if you have any symptoms of flashes of light or floaters in your vision. Different treatment options exist such as laser therapy, cryopexy and surgery which are chosen depending on the severity of the detachment, hole, or tear.

Migraines are often associated with pounding headaches, but they can also affect your vision. Ocular migraines, also known as retinal migraines or visual migraines, are a unique type of migraine that primarily manifests as visual disturbances. This means that the symptoms revolve around your eyes and the way you perceive the world around you. The visual disturbances associated with ocular migraines are short-lived, lasting less than an hour.  

Visual disturbances can include:

  • Flickering lights
  • Shimmering or zigzag lines
  • Temporary blind spots
  • Momentary loss of vision in one eye

Triggers can include:

  • Stress
  • Hormonal fluctuations
  • Specific foods
  • Exposure to bright lights, or even distinct patterns

Although ocular migraines are relatively benign, it’s essential to distinguish them from more serious conditions that can cause similar visual disruptions, such as retinal detachment.

Always seek prompt medical attention if you experience sudden visual changes.
