title: Optical coherence tomography of the suprachoroid after CyPass Micro-Stent implantation for the treatment of open-angle glaucoma.
abstract: OBJECTIVE
  To evaluate the supraciliary space (SCS) with anterior segment optical coherence tomography (OCT) imaging after CyPass Micro-Stent implantation.
  
  
  METHODS
  The SCS was imaged with OCT after microstent implantation at 1, 6 months, and 1 year. Images were graded on a scale of 0-4 for morphological features indicative of fluid presence within, or drainage through, the SCS.
  
  
  RESULTS
  35 patients underwent ab-interno microstent implantation. Mean age was 68.6±10.2 years. Baseline mean intraocular pressure (IOP) was 21.9±6.1 mm Hg on average of 3.0 topical medications. At 1 month, the fluid space grade was ≥1 for 96% (24/25) of patients for tenting, 79% (15/19) for fluid posterior to the microstent, and 89% (8/9) for fluid surrounding the microstent. The mean (composite) score for all features was 2.5±0.99. The majority of patients maintained aqueous fluid through 12 months.
  
  
  CONCLUSIONS
  OCT imaging provides adequate visualisation of the angle, the SCS and aqueous fluid drainage after implantation of a suprachoroidal microstent into the SCS.
