Representative primary open-angle glaucoma eyes with and without optic disc hemorrhage (ODH). (A) A 65-year-old female patient without ODH during follow-up in her left eye. (B) A 64-year-old male patient with a single ODH in his left eye. (C) A 66-year-old male patient with recurrent ODH during follow-up in his left eye. All these eyes presented with choroidal microvascular dropout (CMvD) in the inferotemporal area and superior visual field (VF) loss with similar degrees of damage represented by VF mean deviation (MD). On an optical coherence tomography angiography (OCTA) whole-signal mode en-face image of the optic nerve head (ONH), the blue ellipse indicates the ONH margin and the blue vertical line denotes boundaries of vessel density (VD) measurement areas within the ONH passing across the optic disc center. The boundaries of the ONH (orange outline), excluding large retinal vessels, were manually demarcated. These areas of interest were used to measure the intradisc VD. The intradisc VDs were 37.01% and 37.89% in eyes with single ODH and recurrent ODH, respectively, which were lower than that in an eye without ODH (40.12%).
