BMO with respect to Banach function spaces [PDF]

, 2022
For every cube $Q \subset \mathbb{R}^n$ we let $X_Q$ be a quasi-Banach function space over $Q$ such that $\|\chi_Q\|_{X_Q} \simeq 1$, and for $X= \{X_Q\}$ define \begin{align*} \|f\|_{\mathrm{BMO}_X} &:=\sup_Q \,\|f-{\textstyle\frac{1}{|Q|}\int_Qf} \|_ ...

Differences in optic nerve head structure between acute angle-closure glaucoma and open-angle glaucoma

Scientific Reports, 2023
This study aimed to compare the optic nerve head (ONH) structure in acute angle-closure glaucoma (AACG) and open-angle glaucoma (OAG) to investigate the differences in glaucomatous damage.

Effects of short‐term mild hypercapnia during head‐down tilt on intracranial pressure and ocular structures in healthy human subjects

Physiological Reports, Volume 5, Issue 11, June 2017., 2017
Many astronauts experience ocular structural and functional changes during long‐duration spaceflight, including choroidal folds, optic disc edema, globe flattening, optic nerve sheath diameter distension, retinal nerve fiber layer thickening, and decreased visual acuity. This study investigated whether acute exposure to mild hypercapnia combined with a

The influence of different intraocular pressure on lamina cribrosa parameters in glaucoma and the relation clinical implication

Scientific Reports, 2021
Elevated intraocular pressure (IOP) is one of the main risk factors for glaucoma, and pathological changes in the lamina cribrosa (LC) may play a leading role.
