Coming up on 30 years in ophthalmology- never had a problem with this. The
flash recycling time on most fundus cameras are probably not fast enough to
trigger an attack. You can click as fast as you want- the flash isn’t going to
keep up with you.

Also, since the flash frequencies most likely to provoke a seizure are in the
15 – 25 Hz range, fundus photography and fluorescein angiography are probably
not going to cause a problem.
Unless you have a VERY fast trigger finger…

It is a documented risk in electroretinography. We do not perform ERG on

Hi
Has anyone experience of any incidence of photo-triggered seizure being
triggered by ophthalmic devices or diagnostic procedures.
Thanks
