113 EW CORNEA October 2017 Contact information Maskin: drmaskin@drmaskin.com Tauber: jt@taubereye.com symptoms only apparent after treat- ment. I have also managed patients with neuropathic dry eye-like pain with MGD who did not have lid tenderness, did have expressible glands but on probing were found to have greater than 92% of glands with occult deep obstruction. Prob- ing helped reverse symptoms. The lesson here is that only probing can establish or confirm a patent duct/ orifice outflow tract with positive physical proof of outflow patency. All patients with MGD should be probed to open and/or maintain a patent outflow tract." Dr. Maskin recommends pa- tients have an annual evaluation as clinical benefits can decline over a year after MGP. Dr. Tauber said he recommends retreatment within the first 8 weeks of the first MGP and follow-up as needed thereafter. EW References 1. Maskin SL, et al.
