Causes of Sudden Vision Loss

If you or a loved one is dealing with sudden vision loss, it may seem unreal. How can one go from having fine vision to going blind in an instant? Even more unreal are instances where the vision loss is temporary. A person may lose vision for only a few minutes, have it restored and then lose it again in a few days. What is happening and what are the possible causes?

Wet Macular Degeneration

Macular degeneration is an umbrella term that describes a degeneration of the macula; typically over time. However, there is a certain kind of macular degeneration called “wet” macular degeneration. This can cause a very abrupt loss of sight that may or may not have symptoms such as wavy images, leading up to vision loss. In some instances, wet macular degeneration is not reversible. This is one reason why your Coldwater eye doctor wants you to have regular eye exams.

Retinal Detachment

The retina is a very delicate part of your eye that can tear or become detached from the eye. Retinal detachment may be caused by eye trauma, such as a sports injury or car accident, or it may happen seemingly innocently if it’s been damaged over time. If you or your loved one does experience sudden vision loss, be sure not to touch the eye or pull or tug at the eyelids. If the vision loss is due to retinal detachment, you could risk damaging the retina further. In some cases, the retina can be reattached via surgery, but you would need to get to your eye doctor right away to ensure higher chances of a positive outcome.

Optic Nerve Issues

The optic nerve is responsible for sending signals to your brain in order for you to see. If this transmission is impeded for any reason, vision is diminished. Optic nerve issues can stem from a variety of reasons, including underlying disorders like diabetes. There may even be a growth pressing on the optic nerve that’s preventing the signal from getting through.

Any change in your vision should be taken seriously. Don’t assume it will clear up by itself. Make an appointment with your Coldwater eye doctor for sudden vision problems and always see your eye doctor for routine visits throughout the year.
