You should be evaluated by an ophthalmologist, preferably a retina specialist, with a complete dilated exam including scleral depression, to be sure there is no retinal tear. Just because you have never had an eye problem before, doesn't mean there is no serious injury now. Also, these types of trauma can cause bleeding in the eye and even late-onset glaucoma. See an ophthalmologist ASAP and wear protective eye guards when playing any racquet sports.
I saw a ophthalmologist and he told me that I had fluid, I am guessing he meant vitreous fluid, this explains why I was seeing lights he told me. He said he wanted to see me in two weeks again because the fluid detaching me create a tear? What are the chances of me having a tear two weeks later after I was checked by him?
