PURPOSE To determine the magnitude of the homogeneous, LF(Ho), and the heterogeneous, LF(He), components of the long-term fluctuation (LF) in glaucoma suspects and in stable primary open angle glaucoma (POAG) patients undergoing short-wavelength automated perimetry (SWAP) and to compare the magnitude of the SWAP LF components with those elicited by standard white-on-white (W-W) perimetry. MET...

Methods: Forty eyes of 40 patients with PAC underwent detailed ophthalmic evaluation including applanation tonometry, gonioscopy, optic disc evaluation with +78D lens and achromatic automated perimetry. UBM was performed to evaluate angle parameters before and after LPI to study the trabeculariris angle (TIA), the angleopening distance at 500 mm (AOD) and the central anterior chamber depth (ACD...

High-pass resolution perimetry, or the "ring test," is a recently developed type of acuity perimetry. To determine its test-retest variability, we studied 10 normals and 10 patients with idiopathic intracranial hypertension (IIH) by testing both eyes four separate times. There was no increase in variability from the center out to 21 degrees of visual field eccentricity. However, there was a sig...

OBJECTIVE To compare the ability of 24-2 frequency-doubling perimetry (FDP-Matrix) with standard automated perimetry with the Swedish interactive threshold algorithm (SAP-SITA) in detection of visual function abnormalities in patients with glaucomatous-appearing optic discs (GAOD). METHODS This observational case-control study included 80 patients with GAOD and 54 control subjects diagnosed b...

Aim: To examine whether high spatial resolution perimetry (HSRP) could identify fine scale scotomata which may not be apparent with conventional perimetry. The HSRP was performed in the nasal field, as this location is a recognised site for the early occurrence of glaucomatous defects. Method: 16 early glaucoma eyes, 17 glaucoma suspect eyes, and 20 age matched healthy control eyes underwent co...

PURPOSE To evaluate the diagnostic ability of a new perimetric procedure in glaucoma. METHODS Pulsar perimeter shows white circular sinusoidal grating patterns with decreasing amplitude, 5 in diameter, 500 msec in duration in 66 locations. The stimuli scale combines spatial resolution and contrast. The stimuli were shown with centrifugal wave motion at 8 cyl/deg (K6W) or pulse at 30 Hz (T30W)...

HEALTH POLITICAL BACKGROUND About 950,000 people are affected by glaucoma in Germany, about 50% of which are undiagnosed. The German Ophthalmological Society and the German Association of Ophthalmologists recommend a screening for glaucoma according to their guidelines. The Federal Joint Committee disapproved a glaucoma-screening program on expense of the compulsory health insurance in 2004. ...
