HIGHER PRESSURE WHEN LYING DOWN MAY INDICATE GREATER RISK FOR VISUAL FIELD LOSS

Postural Response of Intraocular Pressure and Visual Field D... : Journal of Glaucoma

Patients with an average change in pressure between sitting up and laying down of 3.2mm Hg had less visual field damage than those patients with an average change in pressure of 4.5 mm Hg.

Conclusions: More advanced visual field damage was observed in eyes with greater increase in pressure with lying down. Therefore, there may be value in measuring the pressure in the supine position at the time of first diagnosis in patients with normal pressure ranges.
