Thanks for using the forum. I am happy to address your questions, and my answer will be based on the information you provided here. Please make sure you recognize that this forum is for educational purposes only, and it does not substitute for a formal office visit with a doctor.
Without the ability to examine and obtain a history, I can not tell you what the exact cause of the symptoms is. However I will try to provide you with some useful information.
Juvenile rheumatoid arthritis can be associated with a condition called chronic anterior uveitis, which is an inflammatory condition of the eye. It is a condition that can be devastating. Thus, frequent eye examinations are crucial. If noticed on examinations, urgent treatment is required.
Optic nerve swelling, i.e., papilledema, is a different finding. There are many things that can cause papilledema such as a brain tumor, head trauma, infection, and blockage of the normal flow of the CSF. It can also be a benign finding. If it was noticed that your child has this, he/she should have an MRI if not already completed. Additionally, frequent eye examinations is important in order to monitor vision. If the optic nerve swelling is causing symptoms, a VP shunt may be placed.
I cannot comment if all of the conditions your child has are related or not. I do recommend that he/she be seen by a physician (i.e., PCP) and also by an ophthalmologist and perhaps a rheumatologist. Additional imaging (i.e., MRI) and visual fields are needed to complete the workup.
Thank you for this opportunity to answer your questions, I hope you find the information I have provided useful, good luck.
thank you for your answer. My son cannot have an MRI as he has metal wire in his chest from heart surgery he had at 14mths, but has had a 'cat scan' and has now had a 'bone scan'. I still cannot get an earlier app with his eye proff but as he is one of the top in the country i am hoping that he would already have made the connection and tested him for this before!! his finding is benign and does get checked but we havent seen the prof since he started having all the pains in his feet/knees..........
