Sub-classification of myopic glaucomatous eyes according to optic disc and peripapillary features.

ABSTRACT:

Purpose

To investigate the sub-classification of myopic glaucomatous eyes by optic disc and peripapillary features.

Methods

Optic disc tilt and torsion were determined from retinal nerve fiber layer photographs. Based on the location of the Bruch's membrane (BM) opening within the β-zone of the peripapillary atrophy (PPA) area, the widths of β-zone PPA (PPA1W), PPA+BM (PPA2W), and PPA-BM (PPA3W) were measured with enhanced depth imaging spectral-domain optical coherence tomography. Cluster analysis that employed partitioning around medoids was performed with these parameters, the presence of inward rotation of BM ending axial length (AXL), and central corneal thickness.

Results

A total of 115 eyes (AXL≥24 mm) were included. Two clusters produced maximum overall silhou
