Hi Dr, My 65 yr old Dad complains of seeing black object with his right eye. This is in a ddition to strong headache . We consulted a local physician who tested him optically and recommended glasses. However, the situation has not improved rather the black object(shadow) is being observed in the left eye. I was a bit alarmed with his level of concern and had to take him to a neurologist given the fact that he is hypertensive. Further tests were done including a brain BEG.We were told all was well with prescriptions made. The situation is still the same. Kindly give your expert advice.
