Clinical evaluation of SITA-standard for Humphrey Field Analyzer.

open access: yesJAPANESE 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。

Detection of glaucomatous visual field defect using a screening program of Humphrey Field Analyzer

open access: yesKorean Journal of Ophthalmology, 1990
To evaluate its clinical efficacy, we report the results of Armaly central field screening test in comparison with those of central 30-2 threshold test of Humphrey Field Analyzer. In 83 cases of normotensives, ocular hypertensives, and glaucoma patients with open-angle or narrow-angle enrolled in this study, a total of 143 eyes were examined.

A comparison of global indices between the Medmont Automated Perimeter and the Humphrey Field Analyzer [PDF]

open access: yesBritish Journal of Ophthalmology, 2007
Two commonly used perimeters in Australia are the Humphrey Field Analyzer II (HFA) and the Medmont Automated Perimeter (MAP). Each device describes the visual field in terms of numerical values called global indices; however, these values are not interchangeable between devices.
