This article is dedicated to main information about visual field, monocular and binocular ranges of visual field including their defects. Visual field loss may occur to disease of the eye, optic nerve or brain. Typical changes are present at glaucoma and macular degeneration. Visual pathway is also

White noise field campimetry is able to transform usually negative scotomas immediately into perceivable visual field defects. As this method needs a monitor, the obvious solution was to evaluate the suitability of the noise field stimulus broadcasted to home TV sets. Therefore, in cooperation with

OBJECTIVE
To evaluate the three commercially available computerized statistical algorithms for determining progression of glaucomatous field loss in serial Humphrey fields.
METHODS
Serial Humphrey fields of 102 ocular hypertensive and glaucomatous eyes were analyzed by linear regression analysis of

BACKGROUND
There are several limitations of the Amsler chart as a screening tool due to its low sensitivity and high false-negative results. The Berkeley central visual field test (BCFT), which is a simple power-point presentation of a 50-point scoring system for the central 10-degree of the visual

OBJECTIVE
Posterior cortical atrophy (PCA) is a progressive neurodegenerative syndrome that presents with cortical visual dysfunction and relatively preserved memory. Although higher cortical visual syndromes are well known in PCA, visual field defects detected by computerized visual field (CVF)

OBJECTIVE
Tilted disc syndrome is a congenital anomaly of the eye characterized by mostly upper temporal visual field defects. The aim of the present study was to evaluate the effect of gradual myopic correction in the improvement of visual field defects associated with tilted disc

Patients with early age-related macular degeneration (AMD) may retain good visual acuity but experience distortion and other qualitative visual changes. The purpose of the present study was to determine whether deficits of form recognition, as well as of light sensitivity, were related to retinal

Full-field electroretinograms were recorded from four infants (under the age of 12 months), with different types of tapetoretinal degeneration. Some of these patients, appear to have normal fundi. This article stresses the clinical usefulness of evaluation with electroretinography in young children.
