Progression patterns of normal-tension glaucoma groups classified by hierarchical cluster analysis.

ABSTRACT:

Objectives

To investigate differences in progression patterns of normal-tension glaucoma (NTG) patients in three clusters classified by hierarchical cluster analysis (HCA).

Materials and methods

In a retrospective study, 200 eyes of NTG patients classified by HCA in 2015 who were followed up to the current date were evaluated. Peripapillary retinal nerve fibre layer (RNFL) thicknesses were measured by Cirrus HD-OCT and progression rate was calculated by trend analysis (Guided Progression Analysis [GPA]). VF progression rate was evaluated by linear regression analysis of mean deviation (MD). Progression patterns of three clusters were compared by histograms.

Results

In total, 153 eyes of 153 patients were followed up. Mean observation period was 5 years. RNFL reduction
