A week ago I experienced some flashes of light on the right

A week ago I experienced some flashes of light on the right side of my right eye. I went to
my eye doctor and she did the usual tests to check for retinal detachment and said everything was okay. Yesterday and today I've experienced a floater like the shadowy outline of a half-halo which moves about. Should I be concerned? I am 74. Thank you so much.

Dr. Dan B. : Hello and thanks for your question. Was the eye doctor you saw an optometrist or ophthalmologist?

An optometrist

Dr. Dan B. : The flashing lights you were experiencing were part of a tractional process on the retina from the vitreous jelly in the back of the eye. It is a tractional process which has produced this half-moon shaped floater. If you've seen an optometrist relatively recently and you're still concerned, I would recommend seeing an ophthalmologist.
Dr. Dan B. : Is quite likely that this tractional process is resolving now that it has produced this floater. However, it is possible that with the onset of this floater that a hole or tear or break the has occurred in the retina. It would be a good idea to see your ophthalmologists as soon as you're able to this week. However, I wouldn't be overly concerned unless you see signs of a retinal detachment which are the following:
Dr. Dan B. : 1. sudden increase in or new floaters, 2. flashing or arcing lights that are frequent or persistent, 3. a shade/shadow/spot in your vision that you can't see light through, or 4. a large drop in your vision which doesn't improve after a few minutes. For any of these symptoms you must see an ophthalmologist as soon as possible.
Dr. Dan B. : Do you have any other questions about this?
