My daughter was hit with a volleyball and experienced very little pain but had difficulty seeing. Her vision returned in a very short time but still complained of a grey patch in the upper half of her vision. A visit to the ophthalmologist brought a diagnosis of a bruised retina . The doctor stated that it was not a tear or detachment but was not very detailed. When we asked what the treatment should be, only then did he say don t play volleyball. My question: Can a bruise become a tear or detachment if my daughter continues to play? Does movement aggravate the injury or is it more the risk of being hit again? Could another impact cause tear/detachment?
