Patient's Query

Hello doctor,

I have been getting flashes on my right eye during the night. It is either a white or orange light. I am concerned.

Welcome to icliniq.com.

Flashes may be due to central cause like irritation in brain for example in migraine (half sided headache) people can see flashes of pattern of light. Do you have any headaches while observing these flashes? Or some local cause in eye can cause flashes. Sometimes jelly in the back of eye starts liquefying and detaches or pulls the retina that can cause flashes of light. This liquefacation of vitreous and its detachment is an aging process but it can occur in young people after some trauma, in high myopia (using minus glasses), or any surgery. This process is called posterior vitreous detachment (PVD). Sometimes (not always) PVD can be associated with a break in retina that can cause floaters or curtain in the vision. That is an emergency for eye examination. So you can visit your eye doctor for a complete eye examination. He or she will guide you accordingly.

Same symptoms don't mean you have the same problem. Consult a doctor now!
