Is This Patient at Risk for Retinal Detachment?

A 62-year old woman with hypertension but no previous ocular history presents to her family physician with a 1-week history of a large floater in the left eye. She reports “a cloud that moves around her visual field” and says that although she can see well enough to watch television, her vision while wearing her glasses is decreased from normal. On further questioning, she also reports that she experienced a single brief episode of “light flashes” in the left peripheral field while gardening 5 days ago. She had a normal eye examination result from her optometrist 6 months ago, with 20/20 corrected vision in both eyes. Do this patient’s symptoms require an urgent ophthalmology assessment?
