Article Abstract
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. The AACG and OAG eyes were matched with regard to global retinal nerve fiber layer thickness (RNFLT). AACG eyes were divided into two subgroups based on the presence of ONH swelling at the onset of AACG. RNFLT, Bruch's membrane opening-minimum rim width (BMO-MRW), and Bruch's membrane opening-minimum rim area (BMO-MRA) were analyzed. Global RNFLT values were similar in AACG and OAG groups, but lower than in the healthy group (P < 0.001). The global BMO-MRW and total BMO-MRA were significantly higher in AACG than in OAG group (P < 0.001, respectively). AACG showed similar global BMO-MRW and total BMO-MRA, irrespective of the presence or absence of ONH swelling, while AACG with ONH swelling was associated with significantly thinner global RNFLT compared to AACG without ONH swelling (P < 0.006). The result of differences in ONH structure between the OAG and AACG, especially the AACG with ONH swelling at the onset of AACG, suggests that the mechanisms of optic nerve damage in the two diseases are different.

ROSAH (retinal dystrophy, optic nerve edema, splenomegaly, anhidrosis, and headache) syndrome is a rare genetic disease caused by variants in alpha-kinase 1 (ALPK1) resulting in downstream pro-inflammatory signaling mediated by the TIFA/TRAF6/NF-κB pathway. Here, we report the design of an ALPK1 inhibitor, DF-003, with pharmacokinetic properties suitable for daily oral dosing. In biochemical assays, DF-003 potently inhibits human ALPK1 (IC = 1.

Purpose: During endoscopic endonasal access to small intraconal masses deep in the orbital apex, a line of fusion between inferior and medial recti is encountered distal to the termination of the common tendinous ring. The intraoperatively viewed length of this segment has not been quantified. To assist clinical recognition of this structure, our study quantifies its length and proposes the standardized nomenclature term of inferomedial extraocular muscle raphe (IM-EOMR).

Purpose: To reassess the anatomic basis of optic disc pit maculopathy (OPM) using swept-source optical coherence tomography (SS-OCT) and to characterize the broader structural abnormalities comprising the optic pit complex.
Methods: Sixteen patients with OPM were imaged using a high-resolution SS-OCT system (DREAM OCT). Cross-sectional and volume-rendered scans were analyzed for lamina cribrosa defects, intraneural cavitations, and pathways for fluid entry into or beneath the retina.

Objective: To investigate the prognostic significance of concurrent monitoring of serum S100 calcium-binding protein A12 (S100A12) and optic nerve sheath diameter (ONSD) in patients with traumatic intracranial hematoma.
Methods: This prospective observational study included 198 patients with traumatic intracranial hematoma from Xingtai Central Hospital (February 2022-June 2024). Serum S100A12 and ONSD were measured at admission and postoperatively, and patients received minimally invasive therapy.
MetabOCT: a clinical trial looking for a metabolomic signature predicting the onset of Leber's hereditary optic neuropathy in healthy MtDNA mutations carriers.

Laboratoire de Biochimie et Biologie Moléculaire, Centre Hospitalier Universitaire, Angers, France.
Introduction: The definition of Leber's hereditary optic neuropathy (LHON) does not take into account a preclinical phase during which the thickness of retinal nerve fiber layer (RNFL) is increased, prior to optic nerve atrophy, reducing the chances of visual recovery.
Objectives: Search for a metabolomic signature characterizing this preclinical phase and identify biomarkers predicting the risk of LHON onset.
Methods And Results: The blood and tear metabolomic profiles of 90 asymptomatic LHON mutation carriers followed for one year will be explored as a function of RNFL thickness and compared to those of a healthy control.
