Relationship between nocturnal blood pressure dip and β-parapapillary atrophy zone choroidal vessel density in normal-tension glaucoma patients.
PLoS One
January 2025
Department of Ophthalmology, Asan Medical Center, University of Ulsan College of Medicine, Seoul, Korea.
Purpose: To investigate the relationship between nocturnal blood pressure (BP) dip and parapapillary choroidal vessel density (pCVD) in patients with normal-tension glaucoma (NTG).
Methods: This study analyzed 267 eyes of 267 untreated NTG patients who underwent 24-hour (h) intraocular pressure (IOP) and ambulatory BP monitoring in the habitual position. Patients were classified into 3 groups [non-dippers (nocturnal BP dip < 10%), dippers (nocturnal BP dip between 10% and 20%, and over-dippers (nocturnal BP dip > 20%)], and pCVDs were measured by using optical coherence tomography angiography (OCTA) images.
In vivo assessment of regional scleral stiffness by shear wave elastography and its association with choroid and retinal nerve fiber layer characteristics in high myopia.
Graefes Arch Clin Exp Ophthalmol
January 2025
Department of Ophthalmology, School of Medicine, Renji Hospital, Shanghai Jiao Tong University, 160 Pujian Road, Shanghai, 200001, China.
Purpose: To evaluate the posterior scleral stiffness of different regions in high myopic eyes and to explore its associations with macular choroidal and peripapillary retinal nerve fiber layer (pRNFL) thickness and vasculature.
Methods: Thirty subjects with high myopic eyes and 30 subjects with low myopic eyes were included in this study. The elastic modulus of the macular and peripapillary sclera at the temporal, nasal, superior and inferior regions were determined via shear wave elastography (SWE).
Comparison of ocular posterior segment parameters in the pediatric population with migraine without aura and tension-type headache.
Turk J Pediatr
December 2024
Department of Pediatric Neurology, University of Health Sciences, Kartal Dr. Lütfi Kırdar City Hospital, İstanbul, Türkiye.
Background: This study aims to compare the posterior ocular structure parameters in children with migraine without aura (MWA), tension-type headache (TTH), and a healthy control group.
Methods: The study included 31 patients with MWA, 29 patients with TTH, and 38 healthy controls between 6 and 18 years of age. For all participants, the detailed eye examination and measurements including peripapillary retinal nerve fiber layer (pRNFL) thickness, central macular thickness (CMT), subfoveal choroidal thickness (SCT), macular vessel densities and foveal avascular zone (FAZ) parameters measured by optical coherence tomography (OCT) and OCT-angiography (OCTA), were obtained from the patient files.
Analysis of choroidal thickness, macular thickness, peripapillary retinal nerve fiber layer thickness, and macular vascular density in children with unilateral amblyopia using swept-source optical coherence tomography and their changes following occlusion therapy.
Taiwan J Ophthalmol
June 2024
Department of Vitreo-Retina, Sankara Eye Hospital, Shimoga, Karnataka, India.
Purpose: The purpose of this study was to analyze choroidal thickness (CT), along with macular thickness (MT), peripapillary retinal nerve fiber layer thickness (RNFLT), and macular vascular density (MVD) using swept-source optical coherence tomography (SS-OCT) in children with unilateral amblyopia, and compare the same with normal fellow eyes and normal eyes of normal children before and following occlusion therapy.
Materials And Methods: This was a prospective, longitudinal study of 60 children (4-18 years); 30 children had unilateral amblyopia and remaining 30 were normal. Group 1 consisted of 30 amblyopic eyes of children with unilateral amblyopia; Group 2 consisted of 30 fellow normal eyes of Group 1; Group 3 consisted of normal eyes of normal children.
Optic Nerve Head Changes in Acute Central Serous Chorioretinopathy: Implications for Glaucoma Risk.
Photodiagnosis Photodyn Ther
January 2025
Istanbul Medeniyet University, Faculty of Medicine, Department of Ophthalmology, Istanbul, Turkey. Electronic address:
Objective: Imaging techniques have demonstrated changes in the choroid and retina in acute central serous chorioretinopathy (CSCR), but the effects on the optic nerve head (ONH) remain unclear. This study investigates ONH structural changes in acute CSCR using enhanced deep imaging optic coherence tomography (EDI-OCT).
Methods: A prospective cohort study included 51 acute CSCR patients and 51 healthy controls aged 18-65 years.
