What Causes Flashes in Your Vision?
The mechanical stimulation of the retina, which is the light-sensitive layer at the rear of the eye, is frequently the origin of visual flashes. There are a number of reasons why this stimulation may happen, including:
1. Vitreous detachment in the posterior (PVD)
Posterior Vitreous Detachment is one of the most frequent causes of flashes (PVD). The material that lies between the lens and the retina is called the vitreous. It has the consistency of gel. The vitreous starts to decrease and separate from the retina as we become older. Light flashes may result from this process tugging at or stimulating the retina. PVD is typically a normal aspect of ageing and is usually benign, however it can occasionally result in issues such retinal tears or detachment, which require immediate medical intervention.
- Retinal Tears or Detachment
Flashes may signify a retinal tear or detachment in more extreme situations. When the retina is tugged too hard, it can tear and cause a detachment, which is the separation of the retina from the back of the eye. This condition is known as retinal tears. If left untreated, this is a dangerous disorder that can cause permanent eyesight loss. Blurred vision, a shadow or curtain effect across a portion of your vision, or an abrupt rise in floaters are common symptoms that accompany retinal detachment flashes. - Migraines with Aura
Another neurological disorder that affects vision, migraines with aura, can also cause flashes of light. In this instance, the flashes are typically a part of a more complicated visual disturbance, such as shimmering lights, blind spots, or zigzag patterns. In contrast to retinal-related flashes, migraine-induced flashes usually last for twenty to thirty minutes and may be accompanied by a headache. - Trauma to the Eyes
Light flashes can be caused by any type of head or eye damage. This can entail getting struck in the eye or having something foreign hit the eye. Temporary flashes may result from the trauma’s mechanical stimulation of the retina. Seeing an eye care expert is crucial to make sure there is no long-term damage, even if the flashes stop.5. Other Causes
Additional reasons for flashes could be uveitis, an infection in the eye, or underlying medical disorders including diabetic retinopathy. Additionally, some drugs or eye operations may cause flashes.
When to Seek Medical Attention?
It’s critical to keep an eye on your symptoms and get medical help if you encounter visual flashes, particularly if:
- The flashes are intense and come on suddenly.
- The number of floaters—tiny, ethereal objects that drift through your range of vision—has significantly increased.
- Your eyesight appears to be obscured by a shadow or curtain.
- You have lately sustained head or eye injuries.
- Other visual abnormalities, such as blurred or lost peripheral vision, accompany the flashes.
A comprehensive eye examination, which may involve a dilated eye exam, is frequently conducted by an eye care specialist to evaluate the condition of your vitreous and retina. They might employ imaging methods like fundus photography or optical coherence tomography (OCT) to get a detailed view of the retina and detect any abnormalities.
