Hi Johnking, Thanks for writing to us. Any blunt injury in and around the eyeball (even if there is no obvious damage ), should be examined carefully as it results in a shock wave throughout the orbit and the globe causing secondary damage to the internal structures of the eye. With your history of injury 3 weeks and a persisting swelling,I would suggest a consultation - to make sure the swelling is just a resolving hematoma (blood clot)and not a bony fracture or deformity by imaging. - for detailed indirect ophthalmoscope examination of the inner layers of the eye(retina and optic nerve and the choroid too). - to make sure her vision is alright . Depending on the findings, the management varies which will be guided by your specialist. So, please don t ignore it. It s still not too late, get a direct consultation to be on the safer side and early intervention if necessary. Hope this helps. Take care.
