The value of visual field indexes in screening and threshold testing of glaucoma
The value of visual field indexes in differentiating between glaucomatous and normal fields was determined using a masked prospective experimental design. Indexes for threshold fields (Humphrey Field Analyser (San Leandro, CA) and screening fields (Henson CFA3000 (Keeler, Windsor, UK) were calculated for 27 patients with primary open-angle glaucoma (POAG) and 20 with ocular hypertension, 20 normotensive glaucoma suspects, and 22 age-matched normal subjects. The mean defect, pattern standard deviation, and corrected pattern standard deviation indexes of the Humphrey Field Analyser correctly identified 93%, 78%, and 78% of patients with POAG, respectively. High correlations were observed between these three indexes (r values, 0.84 – 0.98). The four indexes provided by the screening program of the Henson CFA3000 identified only 48% of patients with POAG. Thus, the indexes from the Humphrey, but not from the screening program of the Henson, can be an effective aid in the detection of glaucoma.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
