If a field shows scattered non-specific depressions, keep in mind that a diagnostic early glaucomatous defect is generally recognized as a repeatable cluster of three or more points on the same side of the horizontal meridian all reaching statistical significance (with one or more points having p<1% significance)the test points adjacent to the blind spot may be ignored. Nonproliferative diabetic retinopathy can also cause scattered visual field deviations, even in mild stages. Additionally, evaluation of the presence of eyelid retraction, amount of eyelid laxity, and changes in the surrounding bony framework and periocular tissues is necessary .
