Eye flashes and floaters are common and tend to appear as people age. Floaters are shadow-like spots or blobs that appear in your vision, while flashes are brief streaks of light that resemble lightning. If you notice an increase in either, it's important to get a comprehensive eye exam to rule out any serious eye conditions.
Eye Flashes can be caused by Migraine, a Posterior Vitreous Detachment or worse a Retinal Detachment.
Eye Floaters can be caused by age, eye injuries, inflamed eyes, retinal tears or detachments or bleeding in the eye.
Eye flashes and floaters can both be diagnosed through a comprehensive eye test at Curtis Vision.
Treatment varies entirely on the underlying cause of your eye flashes.
No Treatment - In some cases flashes may go away on their own and there is no need for treatment.
Medication - Where flashes are a result of migraines, medication can be used to control the symptoms and prevent further episodes.
Laser Therapy - In some cases laser therapy may be required to reduce the frequency of eye flashes.
Eye floaters are usually not harmful and don’t require any treatment. However, in some cases where they cause significant vision disturbances your optometrist may refer you for surgery or other treatments with an eye specialist.
Vitrectomy - This procedure involves the removal of the vitreous humor and replaces it with a saline solution.
Laser Therapy - This involves directing a laser beam at the floaters to break them up into smaller less noticeable pieces.
It is important to discuss any concerns with your optometrist to help determine the best course of action. It is especially important if you experience both flashes and floaters as this can be a sign of a more serious condition such as a retinal tear.
There is no way to prevent eye floaters, however taking care of your eyes and getting regular eye exams can reduce the risk of developing serious eye conditions.
Eye flashes themselves are not dangerous but can be a sign of a more serious eye condition such as retinal detachment.
Eye floaters are small shapes or specks that drift across your field of vision. They may look like black or grey spots, thread-like strands, or cobwebs and are most noticeable when looking at a bright background, like a clear sky or a white wall.
Floaters are caused by tiny clumps of gel or cells inside the vitreous, the clear, jelly-like substance that fills the inside of your eye. As you age, the vitreous shrinks and becomes more liquid, leading to these clumps casting shadows on the retina.
Eye flashes appear as brief streaks or bursts of light, similar to seeing stars. They occur when the vitreous pulls on or rubs against the retina, stimulating it and creating the sensation of light.
Floaters and flashes are common, especially as you age. However, a sudden increase in floaters or flashes can be a sign of a more serious condition, such as a retinal tear or detachment, and should be evaluated by an eye specialist immediately.
In many cases, floaters become less noticeable over time as the brain learns to ignore them. However, they do not disappear entirely. If they are severe and interfere with vision, treatment options like vitrectomy or laser therapy may be considered.
A sudden increase in floaters or flashes can be caused by:
PVD is a common age-related condition where the vitreous gel shrinks and separates from the retina. It often causes floaters and flashes but is usually harmless. However, it can sometimes lead to retinal tears or detachment, which require urgent treatment.
You should see an eye specialist immediately if you experience:
While stress and fatigue do not directly cause floaters or flashes, they can make you more aware of existing ones. If symptoms persist or worsen, it’s important to consult an eye specialist.
Floaters can sometimes indicate a retinal detachment, especially if they appear suddenly or are accompanied by flashes, a shadow in your vision, or significant vision loss. Retinal detachment is a medical emergency and requires immediate attention.
Treatment is usually unnecessary for mild floaters. However, severe floaters that interfere with vision can be treated with:
Yes, frequent or sudden flashes can be a sign of a retinal tear or detachment, especially if they occur with new floaters or vision loss. Seek immediate medical attention if you experience these symptoms.
Flashes can sometimes be caused by migraines, specifically ocular or visual migraines. These flashes usually appear as zigzag lines or patterns and are different from those caused by retinal issues. Migraine-related flashes are typically harmless and temporary.
Floaters and flashes cannot be entirely prevented as they are often part of the natural ageing process. However, maintaining good eye health through regular check-ups, wearing protective eyewear, and managing conditions like diabetes or high blood pressure can help reduce the risk of complications.
Floaters are usually harmless and do not mean you are losing your vision. However, a sudden increase in floaters or flashes could signal a serious condition like a retinal tear or detachment, which requires immediate medical attention.
