A friend of mine Gary, K2ACY from Brigantine, posted on his FB page the following:
He was seeing flashing from one eye and went to Horizon Eye in Manahawkin in July. The doctor said he does not see anything out of the normal.
6 months later he goes to a local Optometrist. After an exam the doctor said go right now to Wills Eye hospital ER in Philadelphia. At Wills Eye they found an eye tumor that was removed and tested as melanoma.
Please keep Gary in your thoughts.
Lessons learned, always get a second opinion if you still have a medical problem that is still there with no answer of why.
