Xen 45 Gel Stent sub-conjunctival filtration. a shows the junction between conjunctival and corneal basal epithelium. b & c) reveal a conjunctival epithelium reach of hyper-reflective goblet cells. d shows the corneo-conjunctival junction with blebs and micro-cysts in absence of inflammatory response. e & f show a regular sub-conjunctival gel stent filtration. g, h, i & l show that the sub-conjunctival filtration approaching the tenonian and the scleral planes becomes more laminar than micro-cystic. m & n show the scleral hyper-reflective plane with basal mixed filtration (micro-cystic and laminar) also documenting a regular vascular loop (black arrow)
