I have flashness in eyes but not headache. It happened after one month of taking ethambutol.
I took an eye vitamin. The eye flashness happened three times in the past six months. I never had eye flashness before. I will schedule a VEP test with SUNY College of Optometry in 42th street, NYC, to see whether there is any change of optic nerve. They need a referral from my ophthalmologist. I have faxed it to SUNY yesterday and will expect a call back from them to schedule an appointment.
