A member asked:

Follow up glaucoma exam dr. said more rnfl loss, but damage hadn't shown up on field test yet. why the delay & how long before it's seen?

A doctor has provided 1 answer

Rnfl: there is no exact time course between Rnfl loss and visual field defect. Indeed it may be possible to lose up to 50 percent of your rnfl before visual field defects appear on standard white on white perimetry. Progressive loss of Rnfl on serial oct scans may indicate that your eye pressure is not under ideal control. But there is also some Rnfl lost yearly just from age related change
