ClinConnect Summary

Each participant undergo the following tests:

1. Standard ophthalmic examination (usual care): Best-corrected visual acuity, biomicroscopy (look at front of eye), intraocular pressure (IOP) using Goldman applanation tonometry, central corneal thickness measurement and fundoscopy (look at back of eye).
2. Octopus Visual Field (OVF) Analyzer using G-top strategy recording mean deviation (MD) and pattern standard deviation (PSD).
3. Heidelberg Edge Perimeter (HEP) standard automated perimetry (SAP) using advanced staircase thresholding algorithm (ASTA).
4. Spectralis optical coherence tomogra...

Eligibility criteria

• Inclusion Criteria:
• • Age \> 18 years.
• • Best corrected visual acuity of 20/40 or better in the tested eye.
• • Spherical refraction within ±5.0 D, and cylinder correction within ±3.0 D.
• * History of glaucoma, defined as:
• • Characteristic of glaucomatous disc damage: (local narrowing, notching, or absence of the neuroretinal rim in the absence of disc pallor elsewhere).
• Exclusion Criteria:
• • Any condition preventing adequate examination of the pupil or visual field testing (e.g. ptosis, dense corneal opacities or lens opacities);
• • Active infection of the anterior or posterior segments of the eye;
• • Any intraocular surgical or laser procedure within the previous 4 weeks;
• • Participants taking a medication known to affect visual field sensitivity, a coexisting intraocular disease affecting visual field, or a problem other than glaucoma affecting color vision will be excluded.
