Patient: 76 years of age, male, POAG, BCVA 0.8 at OS, IOP 8 mmHg.
Medical Ocular History: increased intraocular pressure, catatarct surgery with simultaneous ab interno placement of a collagen glaucoma stent 4 weeks ago.
General Medical History: arterial hypertension.
Purpose: to present the collagen implant (XEN gel stent) in anterior chamber.
Methods: Colour Photography Anterior Segment.
Findings:
Colour Photography Anterior Segment: collagen implant (XEN gel stent) in anterior chamber with aqueous drainage to the subconjunctival space.
Discussion:
Lewis RA (1) reported about ab interno approachs to the subconjunctival space. He described the soft, and permanent ab interno collagen implant (XEN gel stent) to optimize aqueous drainage to the subconjunctival space, and said, that the ab interno placement of the stent offers an alternative for lowering IOP with a minimally invasive procedure.
