入选标准

  • 1. Age 40 years or older, with visual acuity > 6/60 in both eyes
  • 2. Primary open-angle glaucoma including exfoliative or pigmentary glaucoma; added 03/06/2020: or ocular hypertension
  • 3. IOP = 22mmHg to =35mmHg (in the case of a medicated patient at the baseline visit following washout and in the case of a naïve (newly diagnosed) patient at the time of screening)
  • 4. Gonioscopically visible scleral spur for 360 degrees without indentation
  • 5. Ability to visualize the peri-limbal sclera for 360 degrees (using a speculum)
  • 6. Willing and able to participate in the 12-month study, to comply with the study procedures and to adhere to the follow-up schedule
  • 7. Participant capable of giving informed consent

排除标准

  • Individuals with the following characteristics will be excluded from the study (unless specified otherwise, all ocular criteria refer to the study eye only):
  • 1. Contraindications to conventional laser trabeculoplasty (e.g. corneal abnormalities, etc)
  • 2. Angle Closure Glaucoma
  • 3. Congenital or developmental glaucoma
  • 4. Secondary glaucoma except exfoliative or pigmentary glaucoma
  • 5. Presence of any Peripheral Anterior Synechiae (PAS) in the study eye
  • 6. Inability to conduct a reliable visual field (defined as fixation losses, false positives or false negatives greater than 33%)
  • 7. Any of the following visual field findings using the Humphrey visual field analyzer the SITA-standard 24-2 program:
  • 7.1. A visual field MD of less than -12dB
  • 7.2. Greater than or equal to 75% of points depressed below the 5% level and greater than or equal to 50% of points depressed below the 1% level on the PD plot
  • 7.3. At least 50% of points (i.e., 2 or more) within the central 5 degrees with a sensitivity =0dB on the decibel plot
  • 7.4. Points within the central 5 degrees of fixation with a sensitivity <15 dB in both hemifields on the decibel plot
  • 8. A visual field MD of less than -12dB in the fellow eye
  • 9. Cup:Disc Ratio of more than 0.8
  • 10. More than two hypotensive mediations required
  • 11. Prior incisional or laser glaucoma surgery
  • 12. Prior corneal refractive surgery
  • 13. Complicated cataract surgery = 6 months prior to enrollment
  • 14. Presence of visually significant cataract in the opinion of the investigator
  • 15. Clinically significant disease in either eye as determined by the Investigator
  • 16. Clinically significant amblyopia in either eye
  • 17. Women who are pregnant or may become pregnant during the course of the study
  • 18. Added 16/03/2018: Dense pigmentation or haemorrhage in the peri-limbal conjunctiva or anterior sclera
  • 19. In the opinion of the investigator the participant might require other ocular surgery within the 12-month follow-up period, unless for further reduction of their IOP
  • 20. Concurrent treatment with topical, nasal, inhaled or systemic steroids
  • 21. Uncontrolled systemic disease that could impact the ability of the participant to attend follow up visits as per the discretion of the investigator
