Independent Effects of Axial Length and Intraocular Pressure on the Highly Myopic Optic Nerve Head.

ABSTRACT:

Purpose

The purpose of this study was to investigate associations among intraocular pressure (IOP), axial length (AXL), and optic nerve head (ONH) characteristics in highly myopic eyes.

Methods

This retrospective cross-sectional study included highly myopic eyes with a refractive error of ≤-6.0 diopters (D) or an AXL of ≥26 mm, without glaucomatous optic neuropathy. Using IOP profiles, obtained retrospectively over a 5-year period, we assessed maximum, median, and range of IOP readings. We performed cross-sectional measurements of morphometric ONH parameters on fundus photographs and optical coherence tomographic (OCT) images.

Results

The study included 201 eyes (134 individuals) with a mean AXL of 27.6 ± 1.4 mm and a mean maximum IOP of 16.6 ± 3.7 millimeters of merc
