Seeing flashes of light resembling lightning or camera flashes may be a symptom of Posterior Vitreous Detachment, a common eye condition. If left untreated, it could lead to serious complications.
Posterior Vitreous Detachment (PVD) is a condition caused by changes in the vitreous humor, the clear gel-like substance inside the eye. The vitreous humor helps maintain the shape of the eye and transmits light to the retina. As we age or due to certain risk factors like severe nearsightedness, the vitreous humor may degenerate, causing its detachment from the retina and affecting vision. The symptoms include the following:
- Seeing spots or lines resembling worms or cobwebs that move along with your eye movements.
- Seeing vitreous floaters more clearly when looking at bright walls or the sky.
- Seeing flashes of light like lightning or a camera flash, especially in dim or dark places.
If Posterior Vitreous Detachment is not severe, the brain will be able to adjust to the black spots and the visibility of the black spots will decrease on its own, without treatment. However, if the vitreous degeneration is severe, it may lead to retinal tears or retinal detachment.
Doctors may treat this condition with laser therapy or cryotherapy to prevent retinal detachment. If detachment has already occurred, surgery may be performed to remove the vitreous, seal the tear with laser treatment, and use gas or oil to hold the retina in place.
If you experience any unusual eye symptoms, it’s essential to consult a doctor for proper evaluation and care.
