A retinal hole is a condition that can cause blurred vision, and lead to permanent vision problems if left untreated.
There are often no symptoms in the early stages. The condition can be treated. Regular eye examinations can help prevent the holes from causing problems in the long term.
A retinal hole occurs when there is a small gap in the light-sensitive tissue at the back of your eye (your retina). Retinal holes can allow fluid behind this tissue, causing it to detach. If this happens, immediate treatment is required to prevent blindness.
