Symptoms of retinal detachment: flies, flickering and other signs of retinal detachment.

Web. Flashing lights. Tree branches. Lightning. These common phenomena, if seen infrequently, may signal a serious eye condition that requires immediate treatment.

They may indicate a hole or detachment of the retina, the tissue layer that lines the inside of the eye and acts as a gateway to the optic nerve to the brain. When the retina peels off, it deviates from its normal position.

This can cause sharp flashes such as lightning bolts or branches that don’t seem to disappear. Another symptom is “flies”, small dots that move across the field of vision.

Retinal detachment is dangerous because the retina breaks away from the layer of blood vessels that provide oxygen to the eye. If left untreated, it can lead to permanent vision loss.

Retinal detachment can result from physical trauma, such as a blow to the head. In other cases it is due to age and heredity may play a role. It is also more common in people who have had cataract surgery or other eye diseases or disorders.

There are three types of retinal detachment:

  • Rhegmatogenous: This is the most common type of retinal detachment in which a tear or cut in the retina allows fluid to separate the retina from the retinal pigment epithelium. This is the layer of cells that provides nutrition to the retina.
  • Traction: A less common occurrence is when scar tissue on the retina contracts and causes separation.
  • Exudative: This is when the retina becomes inflamed due to disease and fluid can leak out again causing separation.

A similar but less threatening condition is separation of the vitreous humor or watery part of the eye, known as posterior vitreous detachment. In this case, floaters may decrease over time.

However, it is important to get checked immediately if you see floaters.

Retinal detachment can be treated, but it is imperative that this be done at the first appearance of symptoms to increase the chances of recovery and vision protection.

Smaller holes can be treated with laser surgery or cryopexy. In laser surgery, tiny “burns” are made around holes in the retina to push the retina back into place, while cryopexy accomplishes this task by freezing the affected area.

The best thing you can do is to see a retinal specialist immediately. It can be diagnosed and treated. In most cases, a person with a retinal detachment is admitted to the operating room on the same day or the next morning.
