Hi doctor, My son had a fall when he was 6 years old and got epidural hematoma surgery done in the right side of the brain. Recently he had a very bad forehead pain at the sides of the forehead. We showed to eye doctor and he told he has power -2 in right eye and -3 in left eye with axis 20 in right eye and 160 in left eye. I wanted to know whether the fall has caused issue with eyesight or it is not linked. This fall happened a year back. When I checked with neurologist they say EDH was external and is not at all linked to power issue. Any comments or recommendations
