Optic disc in glaucoma: Topography and extent of fluorescein filling defects. 1977

S L Fishbein, and B Schwartz

The topography and extent of localized areas of hypofluorescence or absolute filling defects of the optic discs of glaucomatous patients correlated positively with the loss of visual field. Filling defects tended to cluster at the inferior and superior poles of the optic disc and were closer to the disc margin than to the center. The location of the defects corresponded with the expected site of visual field loss. There was a positive correlation between the percent area of the filling defects and the degree of visual field loss. These observations support the concept that fluorescein filling defects of the optic disc in glaucoma represent areas of ischemia that are highly correlated with loss of visual field.

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.
