I went to the normal optometrist for an eye exam in July of 2016. The doctor referred me to an ophthalmologist for an indistinct ONH border, but I never got around to it. July of 2017 I got another eye exam and she told me that she doesn't think anything has changed, but I should still go get it checked out. I have noticed small visual hallucinations over probably the last year, almost like how I imagine dyslexic people read: words swapped around or just missing. It's gotten much worse over the last month. I'm scheduling an ophthalmologist appointment tomorrow to hopefully distinguish whether it's a physical or psychological issue, but are there any eye related conditions with my two given symptoms? I know that tumors can cause hallucinations, but from my understanding tumors of the optic nerve are very rare with no diagnosis of another disease. Thanks.
