Visual field loss is most likely due to the POAG but has not progressed for over a decade. Goldmann lOPs have been below 20 consistently with good compliance to medications. The C/Ds are large OU but have not changed over the last decade (but have increased over the two decade period). The full medical workup (including antinuclear antibodies and anticardiolipin antibodies) was noncontributory. Because of the known correlation between vein occlusion and glaucoma, the I0P was further reduced with SLT OD.
