Improvement of central retinal sensitivity six months after topical isopropyl unoprostone in patients with retinitis pigmentosa

Indian Journal of Ophthalmology, 2013
Aims: Isopropyl unoprostone (IU), a maxi-K channel activator, is used topically to treat glaucoma, and has been reported to have neuroprotective effects on retinal neurons in vitro and in vivo.

An Artificial Intelligence Approach to Detect Visual Field Progression in Glaucoma Based on Spatial Pattern Analysis. [PDF]

, 2019
Purpose: To detect visual field (VF) progression by analyzing spatial pattern changes. Methods: We selected 12,217 eyes from 7360 patients with at least five reliable 24-2 VFs and 5 years of follow-up with an interval of at least 6 months.

Relationship between structural and functional changes in glaucomatous eyes: a multifocal electroretinogram study

BMC Ophthalmology, 2021
Background The nasal to temporal amplitudes ratio (N/T) of multifocal electroretinography (mfERG) scans measured within 5° of the macula can be used to detect glaucomatous change.

Clinical evaluation of SITA-standard for Humphrey Field Analyzer.

JAPANESE ORTHOPTIC JOURNAL, 2000
Humphrey自動視野計の新しい閾値測定法であるSITA(Swedish Interactive Thresholding Algorithm)の実用性を検討するため、緑内障60例60眼を対象にして、Central 24-2を用い、Full-threshold (Full)とSITA-standard (SITA)の2つの検査結果について検討した。Fullと比較したSITAの検査時間短縮率は48.62%であった。Mean deviation (MD)、Pattern standard deviation (PSD)におけるFullとSITAの比較では高い正の相関が認められた。両検査の結果からFullとSITAは、臨床的に比較可能と思われた。
