Eye flashes or photopsia can be caused by many conditions. Although flashes are harmless, they might indicate some serious eye issue which needs to be addressed immediately. Medical attention should be taken when flashes cause loss of vision and also small spots seem to float from one side to the other, thereby hindering the vision.
Migraines and very severe recurrent form of headaches which last for few hours to many days can cause visual symptoms. The light flashes look like zigzag lines, geometric patterns and sparkles when they occur with a migraine. Flashes might affect one eye or both and occur in the peripheral area of the vision. Light flashes sometime also occur due to ophthalmic migraine, a migraine without a headache.
Posterior Vitreous Detachment
The jelly like substance or the vitreous fluid fill the center of the eye and also gives it shape, is attached to the retina. With age and over time there is shrinking of the vitreous and it begins to detach from the retina. This is known as posterior vitreous detachment. In this the vitreous tugs or pulls on the retina, while the retina gets detached and stimulates it thus causing flashes to occur.
There is no known treatment for posterior vitreous detachment, through regular monitoring of the eye through eye checkups are helpful. Symptoms of this are similar to those of retinal detachment (condition in which there is permanent vision loss).
Retinal Detachment or Tear
Retinal tear and detachment also cause light flashes in the eye. This needs to be treated promptly. In case of permanent vision loss there is detachment of retina at the back of the eye, especially if the detachment takes place over the macula which is the main focus of the vision on retina. When the retina detaches from the eye, it loses the main source of nutrients. As there are photosensitive cells in the retina which are responsible for vision, the results of retina tear are severe.
Retinal damage occurs after trauma or as a complication from diabetes or posterior vitreous detachment. Vitreous gel tends to seep under the retina from the small crevices and holes formed by the retinal thinning. This in turn raises the sections and disconnects it from the eye. This can be corrected by laser treatment, cryopexy or an eye surgery.
A trauma like a hard blow on the head can lead the person to experience flashes of light. Also some medications can lead to toxic levels, like Digitalis can cause flashes of light. The symptoms of eye flashes also occur with macular degeneration, which is an age-related disease and in this the vision reduces gradually.
I have getting eyes itching and water stored inside the eyes with little pain what should I have to do I also have headache with sudden guilt.
My eyes are red from childhood these gets allergy from air, sunlight and change in weather please tell me about some treatment to fought against this wide problem.
Night blindness is also called nyctalopia. It's a type of vision impairment. People with night blindness experience poor vision at night or in dimly lit environments. It is not a disease in itself, but rather a symptom of an underlying problem, usually a retina problem.
What Causes Night Blindness?
A number of eye conditions can cause night blindness, including:
- Nearsightedness or blurred vision when looking at faraway objects.
- Cataracts or clouding of the eye's lens.
- Retinitis pigmentosa, which occurs when dark pigment collects in your retina and creates tunnel vision.
- Vitamin A Deficiency
- Zinc Deficiency
- Dry Eyes
Are the Symptoms of Night Blindness?
The sole symptom of night blindness is difficulty seeing in the dark. You're more likely to experience night blindness when your eyes transition from a bright environment to an area of low light, such as when you leave a sunny sidewalk to enter a dimly lit restaurant. You're likely to experience poor vision when driving due to the intermittent brightness of headlights and streetlights on the road.
How can I Prevent Night Blindness?
You can't prevent night blindness that's the result of birth defects or genetic conditions, such as Usher syndrome. You can, however, properly monitor your blood sugar level and eat a balanced diet to make night blindness less likely.
Orange colored foods are excellent sources of vitamin A, including:
- Sweet potatoes
- Butternut squash
What are the Treatment Options for Night Blindness?
The treatment will depend on its causes.
- Nutrient deficiency (Vitamin A and Zinc) is the easiest to treat.
- If the cause is cataract, you can go for cataract surgery to remove the clouded lens and replace it with artificial intraocular lens. Vision is usually dramatically improved after surgery.
- For dry eye syndrome, lubricate your eyes with artificial tear drops as they provide instant relief. Just make sure that they are without preservatives.
- Diabetic retinopathy can be prevented with tight control over blood sugar, active lifestyle and good dietary habits.
- As for retinitis pigmentosa, unfortunately there are no treatments available. Thankfully, new research is showing that vitamin A might have a slowing effect on the progression of this eye disease. If you wish to discuss about any specific problem, you can consult an ophthalmologist.
