Evaluation of Retinal Nerve Fiber Layer Thickness and Ganglion Cell Complex Progression Rates in Healthy, Ocular Hypertensive, and Glaucoma Eyes With the Avanti RTVue-XR Optical Coherence Tomograph Based on 5-Year Follow-up

Abstract

We determined progression rates for untreated healthy and under treatment OHT and glaucoma eyes with the Avanti RTVue-XR optical coherence tomography. We found that an average RNFLT progression rate faster than -1.5 μm/y, and an average GCC progression rate faster than -1.3 μm/y are strongly suggestive for uncontrolled glaucomatous progression. Detection of uncontrolled structural progression with trend analysis may assist the early detection of fast progressors.
