The GDx Staging System is an efficient way to interpret retinal fibre layer (RNFL) damage.

The GDx Staging System is an efficient way to interpret retinal fibre layer (RNFL) damage, according to a study published in the Journal of Glaucoma.

Dr Paolo Brusini et al., Department of Ophthalmology, Azienda Ospedaliero-Universitaria, Udine, Italy, conducted 320 GDx VCC tests on 84 healthy patients and 236 patients suffering from ocular hypertension or chronic open angle glaucoma. Additionally, the sensitivity and specificity of the GDx was measured in 161 patients with ocular hypertension or chronic open angle glaucoma and 34 normal patients.

The findings showed that sensitivity and the specificity of the GDx were significantly high at 88.2% and 100%, respectively. The results of clinical classification of glaucoma and the Glaucoma Staging System 2 were strongly correlated.

The GDx Staging System is a quick and effective method for classifying RNFL damage, especially for inexperienced ophthalmologists.
