This is a large hole in the retina in a 20 year old patient. It needs fairly urgent attention before it becomes a retinal detachment. There is some fluid under it so part of the retina is already detached. We catch about 2 to 3 patients with retinal holes per week just on routine dilated eye exams. Without dilating, these breaks in the retina cannot be discovered. Therefore the people that go blind from retina detachments are often the ones with perfect vision who don’t come in for exams regularly, because they don’t get discovered until it’s too late.
