I got hit with a ball on the eye. During the day I see fine, but at night I see a dark spot at the bottom of my vision. What does this symptom mean and how is it treated?

The most important thing to do is to see an ophthalmologist or retina surgeon/specialist to examine the retina after a severe injury to the eye, like getting hit in the eye with a ball. A dark spot immediately after an injury could be swelling in the retina which typically subsides, but it could be blood in the eye or a retinal tear or retinal detachment. Those conditions require prompt treatment and could cause loss of vision if untreated.
