<s>[INST] My daughter all if a sudden went crossed eye. She had been complaining about headaches. Being puking. I don t know if it was a slow process but just a week ago she was normal. Then I finally noticed she was closing her left eye to focus. Took her to see eye doctor and they said she needs to see a specialist. Dr. Also. Priced at the exam while following the lights. Her Eyeball would twitch while trying to focus on light. I pray it s not a tumor. And we t seeing her pediatric tomorrow to get a appt for neurologist ? Please some answer. It just happen all of a sudden [/INST] Hi...I am sorry to say that all the points you have quoted are pointing towards a tumor in the brain pressing upon the optic chiasma. She will need an MRI brain too.Regards - Dr. Sumanth </s>
