Ages Eligible for Study:   40 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Patients diagnosed with Open-Angle Glaucoma with a non-optimal intraocular pressure control with topical/oral medications, who underwent to laser trabeculoplasty treatment, attending the Fundacion Oftalmológica Nacional between June 2014 and july 2016 on Bogotá-Colombia.
Criteria

Inclusion Criteria:

  • Subjects of either sex, aged ≥ 40 years
  • Best distant visual acuity, better than or equal to 20/200
  • Diagnosis of primary open-angle glaucoma, pseudoexfoliation glaucoma or pigmentary glaucoma, with open angles by Posner lens gonioscopy
  • Intraocular pressure ≥ 20 mmHg, with medical treatment, as monotherapy or combination therapy.
  • Previous computerized visual field within the six months previous performing trabeculoplasty
  • Patients who understand and sign the informed consent
  • Patient diagnosed with open-angle glaucoma who will undergo selective laser trabeculoplasty (SLT) with an amplitud of 360 degrees, or laser trabeculaplastia in pattern (PASCAL-Pattern Scan Laser) with an amplitud of 360 degrees. Made at initial session or in two 7 days separate sessions (each with session with an amplitude of180 degrees)

Exclusion Criteria:

  • Advanced loss on visual field within 10 degrees of central fixation in a previous 3 months visual field
  • Previous history of surgery for glaucoma management, except peripheral iridotomy
  • Corneal disease that does not allow the use of applanation tonometer nor an accurate measurement of intraocular pressure
  • Corneal disease which prevents adequate visualization of trabeculo by gonioscopy lens
  • Use of topical or systemic steroids
  • Concomitant participation in another study
  • Coexistence of other ocular pathology different than cataract.
