Phosphenes

Phosphenes are a visual sensation that make the person can perceive very small light points, about the size of the tip of a pin, in the campor visual

In most cases the phosphenes are harmless, but if they are recurrent, you have to pay attention, since they can be a symptom of a more serious illness

Phosphenes are the result of an irritation in the retina that, when it happens, makes an impulse that is perceived as a light. The light spots in the eyes are associated with flying flies, retinal detachment, migraine or other conditions.

Phosphenes are the result of an irritation in the retina that, when it happens, makes an impulse that is perceived as a light. The light spots in the eyes are associated with flying flies, retinal detachment, migraine or other conditions.

What are phosphenes?

To meet the definition of phosphenes, just say that are those rays, flashes or very small spots of light that appear in the campor visual After closing the eyes very hard, rubbing the eyelids or receiving a blow to the face.

The rays of light in the campor visual usually appear and disappear very quickly and for no apparent reason.

Also, when a person states that they see lights in their eyes, it is important to identify if it is a phosphene, a photopsy or is a glare. Usually the glare occur due to the presence of an annoying light and interferes in the campor visual In the phosphenes there is no presence of an outside light that can justify the staining. The photopsies, unlike phosphenes, is the feeling of seeing light spots without external light stimuli.

Most of the light flashes or phosphenes occur when vitreous humor is collected or changed and exerts traction on the retina, causing it to react with a stimulus that is perceived as light.

When we rub your eyes or close them tightly that stimulus is also produced, as pressure is being exerted on the retina.

However, although most of the time the presence of phosphenes in the campor visual is not an alarming symptom, it is important to be very attentive if it becomes something regular, since it could be a sign of more serious diseases.

Difference between phosphenes and photopsies

The meaning and differences between phosphenes and photopsies are often confused. This confusion is common because both conditions look very similar, although they keep great differences and have different implications.

La difference between phosphenes and photopsies is that the phosphenes they look like rays or spots of light caused by mechanical stimulation while the photopsies are lueces or flashes that appear in the campor visual without external light stimuli, so the phosphenes can be seen with eyes closed.

Causes of eye phosphenes

When eye phosphenes become a recurring discomfort it is important to attend the ophthalmologist to check eye health and rule out a series of diseases that are associated with these flash of light.

The medical causes of phosphenes are:  

Floating spots

When phosphenes or light spots are accompanied by dark floating spots in the Campor visual, we can usually say that is myodesopsies. There are multiple causes that generate myosopsies, from the less usual as the retinal detachment, Or the uveitis to the most usual, the cataract operation.

In general, the treatment it's simple, just make a laser vitrolysis or, in more serious cases a vitrectomy.

Retinal detachment

El retinal detachment occurs when the vitreous hooks to the retina in such a way that when it took off can pull her exerting such force that I got to part of the retina.

El retinal detachment related to phosphenes could happen if we rub our eyes very hard since what we are doing is press the vitreous humor against the retina to, later, unhook it.

The appearance of phosphenes in the campor visual is, likewise, product of the vitreous traction on retinal tissue.

Migraines

The eye migraine is a Strong headache what can you start with aura episodes in which the person can see spots of lights in the campor visual.

In this case, phosphenes are caused by spasms in the blood vessels of the brain.

Always display that a person has spots of light in the campor visual on a recurring or permanent basis, you should go immediately to the ophthalmologist for a complete review of your visual health.

The main signs why you should see a doctor are: 

  • Start to see spots or rays of light in the campor visual that they didn't see before and that don't disappear. 
  • Increase the amount of phosphenes or light rays in the campor visual
  • See light flashes along with spots or opaque dots.
  • See a dark area in the Campor visual or a kind of curtain that interrupts your vision.
  • See rays of light after suffer a fall or a blow

Light spots on the eyes, what treatment to follow?

Most eye phosphenes do not need treatment, since they do not represent a danger to visual health and disappear by themselves. 

In some cases, when the light rays are abundant and disturb the vision, you can clean the vitreous humor, better known as vitrectomy.

However, it is important to analyze well the need to perform this type of surgical cleaning.  

When the cause of light spots it's the migraine, it is necessary that the person, in addition to the visit with the ophthalmologistattend Consult with a neurologist to take care of headaches and thus avoid the appearance of phosphenes in the campor visual
