Purpose: This study explores the effect of glaucomatous visual field defects on several neuropsychological tests that are often used in research and in clinical settings.
Methods: Nineteen glaucoma patients and nineteen healthy participants, which are current drivers and older than 65 years old were included. All participants completed the Montreal Cognitive Assessment (MoCA), the Trail Making Test (TMT), the Benton Visual Retention Test (BVRT), the Snellgrove Maze Task (SMT) and the Digit Span Test (DST). All participants were also tested on contrast sensitivity and near and far visual acuity. For the glaucoma patients, visual field tests were downloaded from hospital servers.
Results: On the MoCA test, glaucoma patients scored lower than the healthy group, but not significantly. On the MoCA-Blind, the difference was statistically significant. Glaucoma patients also had lower percentile scores on the TMT, with a significant difference in the TMT-A, but this difference largely disappeared in the calculated TMT B-A index, which isolates the cognitive component. The BVRT and SMT showed no significant differences between both groups. In the only non-visual test, the DST, glaucoma patients outperformed the healthy group. Glaucoma severity did not influence results, except for the BVRT on which the moderate/severe group has better scores.
Conclusion: Using visual items might lead to conclusions about cognition when it should be one about vision. Therefore, careful selection of tests is needed when examining cognition in glaucoma patients.

Background: Cerebral autoregulation is a robust regulatory mechanism that stabilizes cerebral blood flow in response to reduced blood pressure, thereby preventing cerebral ischaemia. Scientists have long believed that cerebral autoregulation also stabilizes cerebral blood flow against increases in intracranial pressure, which is another component that determines cerebral perfusion pressure. However, this idea was inconsistent with the complex pathogenesis of normal pressure hydrocephalus, which includes components of chronic cerebral ischaemia due to mild increases in intracranial pressure.

Background: The present study aims to identify the relationship between longitudinal changes in corneal hysteresis (CH) and progressive retinal nerve fibre layer (RNFL) thinning in a cohort of medically controlled, early-to-moderate open-angle glaucoma (OAG) patients with a history of laser refractive surgery (LRS).
Methods: A total of 123 consecutive eyes with a diagnosis of medically controlled (peak intraocular pressure (IOP)<18 mm Hg), early-to-moderate OAG with a history of LRS underwent measurements of CH, corneal-compensated intraocular pressure (IOPcc) and RNFL thicknesses every 6 months. Linear models were used to investigate the relationship between CH change and RNFL thickness change over time.

To analyze the treatment modalities and trends for neovascular glaucoma (NVG) over the past 10 years, we conducted a retrospective analysis at Zhongshan Ophthalmic Center on 1331 NVG inpatients who received 1459 treatments for 1383 eyes between January 1, 2012, and December 31, 2021. Over time, we observed a progressive annual increase in both the number of patients and the volume of surgeries for NVG, with an annual percentage change (APC) of 10.23% (95% confidence interval [CI]: 5.

Purpose: To describe effects of sustained-release steroid delivery devices on intraocular pressure (IOP) in eyes with glaucoma drainage devices (GDD).
Methods: Retrospective case series of eyes with steroid implants (dexamethasone or fluocinolone acetonide) and prior GDD (Ahmed, Baerveldt) without uveitis. Outcomes included IOP, IOP rise, central foveal thickness (CFT), and IOP medications.

Purpose: To describe a case series of presumed Sympathetic Ophthalmia (SO) triggered by diode laser cyclophotocoagulation (CPC) for the treatment of neovascular glaucoma.
Methods: Patients developing bilateral granulomatous uveitis after CPC between 2014 and 2024. Cases with prior ocular trauma or penetrating ocular surgery were excluded.
