Thanks for consulting. I have carefully worked through your case, and I can realize your health worries. Being your physician, I assure you not to worry as I will take care all of your medical concerns. the double vision in case of your son might be due to damage to nerve or muscle that control the eye ball. since they have put a mesh plate some time it may also cause and may be temporary. so kindly consult a ophthalmologist to rule out any nerve injury. Hope it helps. If you need further, detailed and quick assistance related to any health issues in future, feel free to ask me a question directly from my profile. Have a wonderful time ahead. Best Regards! Dr. Arunmozhi varman
