Post hemi -rvo. peripheral retina ischemia. no ultra wide field fa available. can eye drops allow observation of peripheral retina.?

They should be fine: Dilating eye drops (mydriatics) are usually quite sufficient to dilate the pupil wide enough for funduscopic evaluation. With the aide of diagnostic ophthalmic lenses, both direct (contact) ; indirect (non contact), almost the entire retina can visualized under high magnification.

Yes: Yes, not a problem to see the peripheral retina using eye drops.
