Feb 15, 2021 · The GHT highlights how glaucoma damages superior and inferior fields asymmetrically. The GHT compares mirror image clusters of points above and below the horizontal midline to look for significant differences.
Jun 24, 2021 · In patients with higher glaucomatous damage, HAP2 and UKGTS had higher positive rates, indicating higher sensitivities, whereas GHT, Foster, and LoGTS had lower positive rates, indicating lower sensitivities. CONCLUSIONS. No criteria had uniformly superior performance.
Jun 20, 2020 · As glaucoma frequently causes asymmetric defects between the superior and inferior hemifields, the GHT can be a valuable indicator of glaucomatous visual field defects. However, the GHT was not designed to be sensitive to neurological or retinal visual field loss. 7
The GHT results reversal was associated with a large mismatch between baseline VFs. Moreover, the GHT results reversal was associated more with VF archetypes of nonglaucomatous loss, severe widespread loss, and lens rim artifacts.

Jun 3, 2021 · Glaucoma Hemifield Test (GHT) The glaucoma hemifield test was designed to detect glaucomatous visual field loss with high sensitivity and specificity and provides an easy-to-read analysis. It is not sensitive for retinal or neurological field loss.
Oct 3, 2019 · Considering GHT, Sekhar et al38 have previously described sensitivity of 95%, and Susanna et al39 a sensitivity of 100%, but obviously sensitivities depend on the stage of glaucoma that is studied.
