PURPOSE Neural networks were trained to interpret the visual fields from an automated perimeter. The authors evaluated the reliability of the trained neural networks to discriminate between normal eyes and eyes with glaucoma. METHODS Inclusion criteria for glaucomatous and normal eyes were the intraocular pressure and the appearance of the optic nerve; previous visual fields were not used. Th...

AIM To evaluate the performance on automated perimetry (AP) after listening to a Mozart sonata in normal subjects naive to AP. METHODS 60 naive normal subjects underwent AP (SITA 24-2). The study group (30 subjects) underwent AP after listening to Mozart's Sonata for Two Pianos in D Major and the control group (30 subjects) underwent AP without previous exposure to the music. RESULTS The st...

PURPOSE To develop and test a short and reliable visual field threshold program for the early detection of glaucomatous visual field loss, by adapting the Swedish interactive test algorithm (SITA) to short-wavelength-automated-perimetry (SWAP). METHODS Computer simulations were performed to test the accuracy of several versions of SITA SWAP, and to optimize speed versus reliability. The selec...

AIMS To determine principles which regulate the occurrence of angioscotomata in automated static perimetry, variations in light sensitivity were correlated with the location and diameter of neighbouring retinal vessels. METHODS Ten normal eyes were tested with the Octopus 2000R, using a 0.431 degree light stimulus. Sensitivity was quantified in points located around the blind spot, according ...

AIM To assess functional impairment in terms of visual acuity reduction and visual field defects in inactive ocular toxoplasmosis. METHODS 61 patients with known ocular toxoplasmosis in a quiescent state were included in this prospective, cross-sectional study. A complete ophthalmic examination, retinal photodocumentation and standard automated perimetry (Octopus perimeter, program G2) were p...

PURPOSE To investigate the correlation between retinal nerve fiber layer (RNFL) thickness determined by optical coherence tomography (OCT) and visual field (VF) parameters in patients with optic atrophy. METHODS This study was performed on 35 eyes of 28 patients with optic atrophy. RNFL thickness was measured by OCT (Carl Zeiss, Jena, Germany) and automated perimetry was performed using the H...

BACKGROUND An evaluation of standard automated perimetry (SAP) and short wavelength automated perimetry (SWAP) for the central 10-2 visual field test procedure in patients with age-related macular degeneration (AMD) is presented in order to determine methods of quantifying the central sensitivity loss in patients at various stages of AMD. METHODS 10-2 SAP and SWAP Humphrey visual fields and s...
