Hello doctor, A brown color dot along with a white color substance is floating in my left eye. What to do?
Hello. I have gone through what you have mentioned, these dots are called floaters in medical terminology. I can tell you that such a problem arises due to a cause mostly in the back portion of the eye (vitreous or retina). This requires a dilated retinal examination by an ophthalmologist. A single floater which has been present for at least 6 months to a year has no major implications and is nothing to be worried about. I advise you to see the ophthalmologist urgently in case of the following:  Multiple floaters or sensation of flashing lights or blurred vision in either eye. Floaters appeared after being hit in the eye, pain, redness in either eye. If you are a diabetic or on anticoagulant treatment or suffer from blood clotting or blood vessel or autoimmune diseases.
