Variability in isopter position and fatigue during semi-automated kinetic perimetry.

BACKGROUND Assessment of factors influencing response variability to repeat presentations of III4e stimuli and the fatigue effect during semi-automated kinetic perimetry (SKP). DESIGN Prospective case series; setting: university hospital. PARTICIPANTS 58 patients with severe visual field loss: 21 with glaucoma, 18 with retinitis pigmentosa, and 19 with postchiasmal visual pathway lesions. ...

Comparison of Octopus Semi-Automated Kinetic Perimetry and Humphrey Peripheral Static Perimetry in Neuro-Ophthalmic Cases

Aim. To compare semikinetic perimetry (SKP) on Octopus 900 perimetry to a peripheral static programme with Humphrey automated perimetry. Methods. Prospective cross-section study comparing Humphrey full field (FF) 120 two zone programme to a screening protocol for SKP on Octopus perimetry. Results were independently graded for presence/absence of field defect plus type and location of defect. Re...

Quantification of stato-kinetic dissociation by semi-automated perimetry

The difference in threshold sensitivities that are found when examining the visual field (VF) with static versus kinetic perimetric methods is called stato-kinetic dissociation (SKD). In this pilot study, we describe a semi-automated procedure for quantifying SKD. Fifteen patients with VF defects were examined with kinetic and static perimetry. SKD values were defined as positive when the stati...

Variability components of standard automated perimetry and frequency-doubling technology perimetry.

PURPOSE To evaluate and compare intra- and intertest variability components for both standard automated perimetry (SAP) and frequency-doubling technology (FDT) perimetry in a small group of normal individuals and patients with glaucoma. METHODS The method of constant stimuli (MOCS) was used to examine matched test locations with both SAP and FDT perimetry stimuli in a group of eight normal in...
