• The primary endpoint is the difference between groups in absolute change in Humphrey visual field mean deviation at 18 months. — Transcorneal electrical stimulation for the treatment of visual field defects in patients with open-angle glaucoma: a monocentric, randomised, double-masked, sham-controlled pilot study: the TES-GPS study protocol
• Humphrey 24-2 standard static threshold perimetry is used because it provides reliable glaucoma measurements. — Transcorneal electrical stimulation for the treatment of visual field defects in patients with open-angle glaucoma: a monocentric, randomised, double-masked, sham-controlled pilot study: the TES-GPS study protocol
• Mean deviation represents the average difference between age-corrected normal sensitivity and measured threshold sensitivity across test locations. — Transcorneal electrical stimulation for the treatment of visual field defects in patients with open-angle glaucoma: a monocentric, randomised, double-masked, sham-controlled pilot study: the TES-GPS study protocol
• Visual fields are considered unreliable and repeated when fixation losses are at least 25%, false negatives at least 30%, or false positives at least 30%. — Transcorneal electrical stimulation for the treatment of visual field defects in patients with open-angle glaucoma: a monocentric, randomised, double-masked, sham-controlled pilot study: the TES-GPS study protocol
• The study eye is always tested first, followed by the fellow eye, and measurements are then repeated in the same order. — Transcorneal electrical stimulation for the treatment of visual field defects in patients with open-angle glaucoma: a monocentric, randomised, double-masked, sham-controlled pilot study: the TES-GPS study protocol
