Most commonly caused by trauma, retinal detachments can lead to irreversible vision loss if not detected and treated early. The retina can be compared to the ‘film in a camera’ and once it is detached from the eye the tissue quickly dies and vision can not be restored once this occurs. High amounts of myopia (short-sightedness) can also increase the risk of retinal detachment and so any person with a moderate to high amount of myopia should be routinely examined for weaknesses in the retina. The most common signs of a retinal detachment are flashing lights and black spots or floaters in your vision. If you are witnessing any of these signs than you need to have your eyes checked as a matter of urgency.
