Hello...I've been followed as a Glaucoma Suspect for the past couple of years and had baseline exams and followups (VF, Dilation, IOP & HRT etc) Everything looked stable with the exception of the last HRT. (IOP in the low to mid 20's, suspicious nerves (0.45 and 0.55) and fields). The HRT baseline was WNL (p > .05). However, after two additional followup HRT images taken within the last two years, it showed very subtle progression or change from baseline - a few red dots (don't know the specific measurements) but still WNL. Could this indicate very early signs or perhaps pre-clinical glaucoma even if the HRT is still well within normal? From what I understand, the values are taken from a normative database based on age & race. There seem to be so much gray area in making a diagnosis.
