Minimally invasive glaucoma surgeries (MIGS) and their results from the last decade have re-invigorated glaucoma anterior segment thought and research. Trabecular MIGS moved from basic goniotomies/trabeculotomies  to using electrocautery or bypass shunts to overcome TM-related resistance by connecting the anterior chamber directly to Schlemm’s canal . While IOP lowering has occurred, inconsistent results have naturally led to further consideration of either post-TM resistance seen in the physiologic experiments above (Table 1; green and red arrows) or a re-evaluation of AHO patterns [7–10].
