HI, my child had and injury on his face the blackness spread to the eye. This was on May 2014, I took him to his pediatrician he had his eye check, x ray but he still has a black mark under his eye, the pediatrician says is allergy? I believe is something else it has been to long and the eye drops for the allergy has not reduce the mark.
Thanks for posting your query at Chat Doctor. By blackness do you mean a black circle around the eye, what is commonly called black eye? Let me mention that the tissue around the eyes is loose and does not contain much fat padding. As a result, in case of an injury to the forehead or any other area close by, when some amount of bleeding occurs, it gets accumulated in the loose connective area surrounding the eyes. With time as the blood becomes degraded, the color changes from red to brown, purple, bluish and blackish. This is what gives rise to a black eye. In a week or so, it resolves spontaneously without any treatment. So, you need not worry about that. Stay relaxed. Hope I could clarify your doubt. Feel free to revert in case of any other further queries.
