Eye pain due to neuropathic pain.

I have had eye pain in my right eye for a long time, I have been to eye clinics multiple times in the past 1 year and had  dialation tests etc. They couldn't find anything wrong and always prescribed me lubrication drops and were diagnosed with dry eyes. It didn't help a bit with eye pain but finally in my recent consultation with a doctor after telling my history, he diagnosed me with neuropathic pain and prescribed me oxetol which finally worked and provided me with 70-80% relief. I was looking to follow up with him but he is unavailable, so I am looking for any advice on who to follow up with to get rid of the residuals. Is connecting with neurologist a good idea or should I continue with an eye doctor. Any advice is appreciated. Thanks
