ERG preparation

I'm getting an ERG test tomorrow morning.  Recently I had an infection in the eye and was prescribed Erythromycin ointment 0.5% and Fluorometholone 0.1% drops.  Can I continue to use these medications up to the appointment or should I stop using them before the ERG exam (if the lattter, how long before)?  Thanks in advance.

Use the ointment at bedtime and the FML as directed. They won't interfer with the test.
