What does the error message “Uncorrected astigmatism or too high too deep”’ mean?
This message can indicate several things: – Soiled lens – clean the lens with micro-fiber cloth – Camera is misaligned – realign camera center in the pupil and ensure distance to eye is within 10 mm – Very small pupil – dilate if possible – Uncorrected astigmatism – Focal plane is too anterior for a deep cup or too posterior for an optic nerve with elevated areas – adjust focus if incorrect – In advanced glaucoma cases – the patient’s cup may actually be deeper than 4mm and an image cannot be acquired.
