: The PreserFlo™ MicroShunt (PFMS) is a bleb-forming device considered to be less invasive than traditional glaucoma surgery such as trabeculectomy. This study evaluates the 1-year success rates as well as safety profile of PFMS in patients having high intraocular pressure (IOP) and/or glaucoma refractory to drop therapy with a history of prior intravitreal dexamethasone therapy. : A total of 16 eyes after PFMS implantation due to elevated IOP after intravitreal dexamethasone implant (DEX-I) administration were included in this retrospective cohort study.

Ultrasound sonography could be used for more detailed visualisation. The aim of this study was to describe bleb configuration after PAUL glaucoma implant (PGI) surgery and evaluate the possible correlation with intraocular pressure (IOP) in order to derive new markers for evaluating GDD function.

- Saccadometry is an advanced test designed to evaluate the brain regions responsible for fast and precise eye movements through prosaccade and antisaccade tasks that increase in difficulty.
- The study aimed to create a simplified clinical saccadometry protocol using video oculography to establish evaluation standards for adults aged 18 to 69.
- Results showed age and gender differences in various eye movement metrics, highlighting the potential of saccadometry as an objective tool for clinicians to assess complex cognitive and motor functions.
Background: Research on the otolith organs remains inconclusive.
Objectives: This study seeks to further elucidate utricular function in patients with Meniere's disease (MD) in three ways: (1) We aimed to disambiguate the role of the Subjective Visual Vertical (SVV) and Ocular Vestibular Evoked Myogenic Potential (o-VEMP) tests regarding which utricular subsystem each is measuring. (2) We sought to characterize the acute and chronic state of MD by identifying differences in the relationship of SVV and o-VEMP results across patients with acute and chronic MD.
Prcis: This retrospective study of 264 eyes having inferior quadrant trabectome surgery confirms its safety and relative effectiveness. Most patients however still require IOP-lowering agents, and a considerable proportion may need additional glaucoma surgery.
Purpose: To report outcomes from a large single-center cohort of inferiorly-applied trabectome surgery.
