Screening for glaucomatous visual field loss with automated threshold perimetry. 1987

A Sommer, and C Enger, and K Witt

We examined 27 glaucomatous eyes and 154 normal eyes with automated threshold perimetry. Previously suggested algorithms for detecting mild to moderate glaucomatous visual field loss, primarily by comparing the sensitivity of corresponding clusters of points above and below the horizontal meridian, yielded results remarkably consistent with those of our earlier series: 93% (25 of 27) of abnormal and 88% (135 of 154) of normal eyes were correctly identified. Excluding unreliable examinations increased specificity from 88% to 93%. Test duration was similar to results with the Field Analyzer's older, purportedly slower operating system.

UI	MeSH Term	Description	Entries
D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D005901	Glaucoma	An ocular disease, occurring in many forms, having as its primary characteristics an unstable or a sustained increase in the intraocular pressure which the eye cannot withstand without damage to its structure or impairment of its function. The consequences of the increased pressure may be manifested in a variety of symptoms, depending upon type and severity, such as excavation of the optic disk, hardness of the eyeball, corneal anesthesia, reduced visual acuity, seeing of colored halos around lights, disturbed dark adaptation, visual field defects, and headaches.
