The less myopic eye had greater optic disc rotation and glaucomatous visual field (VF) defect.

(A) Fundus photographs of a 49-year-old woman with primary open-angle glaucoma and myopia (spherical equivalent [SE], -5.5 diopters [D]; axial length [AL], 25.79 mm in the right eye and SE, -6.25 D; AL, 26.02 mm in the left eye). (B) The optic disc of right eye showed a tilt ratio of 1.27 and inferior rotation degree of 25.9°. The optic disc of left eye showed a tilt ratio of 1.21 and inferior rotation degree of 14.8°. Inferotemporal retinal nerve fiber layer (RNFL) defect in the right eye was found (arrow). (C) In the RNFL deviation map of spectral-domain optical coherence tomography (SD-OCT) imaging, there was inferotemporal RNFL defect in the right eye. (D, E) Superior nasal step VF defect in the right eye was found. The mean defect on automated perimetry was 3.0 decibels (dB) in the right eye and -1.5 dB in the left eye.
