Eligibility Criteria

Age20 Years - 80 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Clinical diagnosis of refractory glaucoma defined as uncontrolled IOP (\> 21 mm Hg) despite maximal antiglaucoma medication, previously failed surgical treatment, or a combination thereof

You may not qualify if:

  • No light perception
  • elevated IOP associated with silicone oil
  • previous glaucoma drainage device implantation in the same eye
  • previous cyclodestructive treatment
  • increased risk of endophthalmitis (e.g., active adnexal and ocular surface infection, immunosuppression, or immunodeficiency, including the use of systemic steroids)
  • posterior segment disorders, or pre-existing ocular comorbidities (e.g., pterygium, phacodonesis, corneal opacity, or corneal endothelial dystrophies).
  • Only 1 eye per patient was included in this trial.
