Flashes of light are most common in adults over 50 due to age-related changes in the vitreous gel. However, people with nearsightedness, previous eye injuries, a history of retinal problems, or those who have had cataract surgery are also at increased risk.
Suddenly seeing new floaters and flashes could mean your retina has torn or detached. This is a very serious condition that your ophthalmologist must treat quickly to prevent blindness. There is no treatment for occasional flashes of light caused by vitreous changes from aging.
How quickly do I need to see a doctor for flashes? If you have sudden new flashes, especially with floaters or vision changes, you should see an eye specialist the same day. If you have flashes with a dark shadow in your vision, go to the emergency room immediately.
Symptoms include a disturbance in vision which can manifest in a variety of ways. For example, blurring can occur, there can be a reduction in colour vision, particularly for the colour red, with some describing seeing flashing or flickering lights.
If you suddenly see flashes or lose part of your vision – especially in one eye or one side of your visual field – it may be a warning sign of a stroke in the back of the brain (posterior circulation stroke) [1]. These types of strokes can cause: Sudden visual loss or field deficits.
To help you remember some of the signs of a TIA or stroke, use B.E. F.A.S.T.:
Warning Signs of Stroke
There are lots of symptoms that MS can cause, but not everyone will experience all of them.
Sometimes people have light flashes that look like jagged lines, shimmering spots, or heat waves. These can appear in one or both eyes and may last up to 60 minutes.
Four primary types of MS are recognized: relapsing-remitting MS (RRMS), primary progressive MS (PPMS), secondary progressive MS (SPMS), and progressive relapsing MS (PRMS). Each type of MS has a unique pattern of symptoms and disease progression.
Symptoms of eye stroke
Most people with an eye stroke notice a loss of vision in one eye upon waking in the morning with no pain. Some people notice a dark area or shadow in their vision that affects the upper or lower half of their visual field. Other symptoms include loss of visual contrast and light sensitivity.
Many people will see occasional flashes of light, especially as they age. These occasional flashes are usually harmless, but you should discuss them with your ophthalmologist during an eye exam.
Flashes may also be confused with other vision changes, like large spots in your vision. As such, they may signal other medical conditions, including macular degeneration, hypertension, stroke, and diabetes.
What are MS eye symptoms?
Flashes typically last only a moment and may happen more often when you move your eyes or are in a dark room. Unlike floaters that drift slowly across your vision, flashes disappear quickly but their sudden appearance should never be dismissed.
Symptoms
The exact cause of multiple sclerosis is unknown, but research points to specific MS risk factors. Viruses: Exposure to certain viruses, such as Epstein-Barr virus (which causes mononucleosis) and human herpes virus-6, has been linked to an increased risk of developing multiple sclerosis.
In autoimmune diseases like multiple sclerosis (MS), inflammation affects the brain, optic nerve, and spinal cord. Some people develop problems with other organs, including the liver, kidneys, and spleen, due to certain MS symptoms.
Symptoms of multiple sclerosis (MS)
Some of the most common symptoms include: feeling extremely tired (fatigue) problems with your eyes or your vision, such as blurred vision or eye pain. numbness or a tingling feeling in different parts of the body.
Some of the more common glaucoma symptoms include:
MS eye floaters
Eye floaters are a relatively common vision problem among people with MS. Eye floaters are small shapes that drift across your vision. People describe them as: Black or grey specks.
Sometime after about age 55, you may experience the onset of larger, more bothersome floaters or flashes of light. By this age, the vitreous gel has usually become much more watery. It jiggles around quite a bit when you move your eye, making flashes and floaters much more common.
So while MS can occur at any age, it mostly makes its first appearance in people between the ages of 20 and 40. Low levels of vitamin D and low exposure to sunlight, which enables our body to make vitamin D, are associated with an increased risk of developing MS.
The hot bath test reflects the effect of heat that many people with MS notice. Hot weather, hot baths or showers, exercising or an infection can all raise your internal body temperature. The raised temperature can cause your MS symptoms to appear or worsen. This is known as Uhthoff's phenomenon.
The 'MS hug' is symptom of MS that feels like an uncomfortable, sometimes painful feeling of tightness or pressure, usually around your stomach or chest. The pain or tightness can feel like a tight band stretching under your breasts, around the ribs and back or stomach, or it can be just on one side.
