Due to the increasing prevalence of high myopia around the world, structural and functional damages to the optic nerve in high myopia has recently attracted much attention. Evidence has shown that high myopia is related to the development of glaucomatous or glaucoma-like optic neuropathy, and that both have many common features. These similarities often pose a diagnostic challenge that will affect the future management of glaucoma suspects in high myopia. In this review, we summarize similarities and differences in optic neuropathy arising from non-pathologic high myopia and glaucoma by considering their respective structural and functional characteristics on fundus photography, optical coherence tomography scanning, and visual field tests. These features may also help to distinguish the underlying mechanisms of the optic neuropathies and to determine management strategies for patients with high myopia and glaucoma.

Department of Refractive Surgery, Shanghai Aier Eye Hospital, Shanghai.
Purpose: To analyze the effects of ablation interruption on ablation depths and clinical refractive outcomes to characterize the impact of ambient temperature changes and ablation interruption on ocular surface temperature (OST) during excimer laser ablation.
Methods: This prospective study was conducted on laser ablations in polymethylmethacrylate (PMMA) plates and porcine corneas to simulate laser in situ keratomileusis (LASIK) treatments using the EX500 laser (Alcon Laboratories, Inc) at ambient temperatures of 18, 20, and 22 °C. Ablation interruption was performed for 1, 2, 3, 4, and 5 seconds at the 10th second of the treatment of -9.

Purpose: To compare postoperative vault measurements between horizontal and vertical fixation of the Implantable Collamer Lens (ICL) (KS-AquaPORT; STAAR Surgical) when its size is determined using the KS formula.
Methods: This retrospective study analyzed 2,343 eyes from 1,275 patients who underwent myopic ICL implantation. Pre-operative anterior segment optical coherence tomography (AS-OCT) (CASIA 2; Tomey Corporation) was performed in both horizontal and vertical orientations.

Purpose: To evaluate intraocular lens (IOL) power calculation of a non-diffractive extended depth of focus (EDOF) IOL after myopic laser in situ keratomileusis (LASIK) without historical data.
Methods: In this consecutive case series, patients who had undergone lens surgery with implantation of a non-diffractive EDOF IOL after myopic laser in situ keratomileusis (LASIK) at the Department of Ophthalmology, University Hospital Frankfurt, Frankfurt, Germany, were included. Preoperative assessments included biometry and tomography using Scheimpflug technology (Pentacam; Oculus Optikgeräte GmbH).

Purpose: This study aimed to investigate the prevalence, healthcare resource utilization (HCRU) and associated costs of myopia in Germany, comparing mild/moderate and high myopia across various age groups using real-world data.
Methods: A retrospective cross-sectional study was conducted using data from the WIG2 benchmark database. Patients with a diagnosis of myopia (ICD-10-GM H52.

Purpose: To characterize the 3D structural phenotypes of the optic nerve head (ONH) in patients with glaucoma, high myopia, and concurrent high myopia and glaucoma, and to evaluate their variations across these conditions.
Design: Retrospective cross-sectional study.
Participants: A total of 685 optical coherence tomography (OCT) scans from 754 subjects of Singapore-Chinese ethnicity, including 256 healthy (H), 94 highly myopic (HM), 227 glaucomatous (G), and 108 highly myopic with glaucoma (HMG) cases METHODS: We segmented the retinal and connective tissue layers from OCT volumes and their boundary edges were converted into 3D point clouds.
