Article Abstract
Purpose: To measure the time and clinical resources taken to obtain 6 reliable visual field (VF) tests for glaucoma in a glaucoma clinic.
Design: Longitudinal, prospective study in a glaucoma clinic.
Subjects: Ten thousand and ten SITA-Faster VF tests of 535 clinical subjects.
Methods: The cumulative number of VF tests with false-positive rates ≤15% for each eye of each subject was counted over time, and from there, the time to achieve 6 VF tests was determined and compared under frontloaded (2 VFs per eye per visit) and non-frontloaded (first VF within the frontloaded set) conditions. Costs to attain 6 VF tests were modeled.
Main Outcome Measures: Visual field counts and costs for attainment.
Results: Eight thousand nine hundred thirty-one of the 10 010 VF results had a false-positive rate of ≤15%. Approximately 90% of subjects had early or moderate open-angle glaucoma. When using the frontloading protocol, it took an average of 1.4 years to attain 6 reliable VFs for right and left eyes, respectively. For the non-frontloaded protocol, the average times were 2.6 and 2.5 years for the right and left eyes, respectively; 82.5% of right eyes and 85.4% of left eyes achieved 6 reliable VFs within 2 years when frontloaded, but the proportion was only 15.8% and 18.8% when non-frontloaded for right and left eyes, respectively. There was a significantly lower cost for obtaining 6 reliable VFs with frontloading than non-frontloading, due to fewer office visits.
Conclusions: A frontloading approach and SITA-Faster paradigm led to patients attaining 6 reliable VFs over 14 months sooner than non-frontloaded, with >84% receiving the recommended number of 6 tests in the first 2 years. The frontloading approach overall leads to savings in time and cost in comparison to non-frontloading for achieving 6 reliable VFs and thus potentially provides an avenue for earlier detection of glaucomatous change.

Glaucoma is a globally prevalent disease that leads irreversible blindness. The visual field (VF) examination is important but time-consuming for visual function evaluation with high requirement of cooperation and reliability of patients. While color fundus photographs (CFPs) are easy to access.

The invasion of moso bamboo significantly alters aboveground vegetation, yet its impact on soil microbial communities and associated ecological functions remains under-explored. To address this knowledge gap, we conducted a comprehensive survey across 24 sites spanning varying invasion gradients (non-invaded, half-invaded, fully-invaded) along an urbanization transect encompassing mountain, rural, suburban, and urban habitats. Our results reveal that bamboo invasion strengthens deterministic processes governing microbial community assembly.

Objective: Listening-related fatigue can be a significant problem for some people with hearing loss. However, such fatigue is rarely assessed by audiologists due, in part, to the scarcity of assessment tools, especially in non-English languages. The goal of this study was to validate the short and long versions of the Spanish Vanderbilt Fatigue Scales for Adults (SP-VFS-As).

Laryngeal high-speed video (HSV)-endoscopy allows for fast, non-invasive diagnosis of voice disorders and forms the basis for a comprehensive quantitative analysis of the vocal folds' (VFs') spatiotemporal vibrational behavior. Previous approaches, such as the Phonovibrogram (PVG), describe the vibrational behavior of vocal folds (VFs) based exclusively on the time-varying glottal opening. However, focusing solely on the glottal area overlooks the full extent and dynamic behavior of the VF tissue, factors that are crucial for the voice production process.
