Utility of CLOCK CHART binocular edition for self-checking the binocular visual field in patients with glaucoma.

Background/aims: Car accidents caused by drivers unaware of their visual field (VF) defects under binocular vision have become an issue. We developed a simple self-check chart (CLOCK CHART binocular edition (CCBE)) to help patients with glaucoma recognise their abnormalities in the binocular VF and evaluated its usefulness.

Methods: The chart has four targets displayed at 10°, 15°, 20° and 25° eccentricities.

Distribution and Progression of Visual Field Defects With Binocular Vision in Glaucoma.

Purpose: To evaluate the distribution and progression of glaucomatous visual field (VF) defects with binocular vision.

Patients And Methods: Subjects were 167 patients (average age, 67±10.7 y) with glaucoma who received the Humphrey 24-2 VF test (SITA-Standard) for the 2 eyes.

Test Conditions in Macular Visual Field Testing in Glaucoma.

Purpose: The purpose of this study is to evaluate the suitable visual field (VF) test conditions (target size, test type, and eccentricity) for the macular region, we investigated the correlations between the ganglion cell layer (GCL) thickness and 6 VF test results.

Methods: We tested 32 eyes of patients (61.1±9.

Effects of head tilt on visual field testing with a head-mounted perimeter imo.

Purpose: A newly developed head-mounted perimeter termed "imo" enables visual field (VF) testing without a fixed head position. Because the positional relationship between the subject's head and the imo is fixed, the effects of head position changes on the test results are small compared with those obtained using a stationary perimeter. However, only ocular counter-roll (OCR) induced by head tilt might affect VF testing.

Evaluation of kinetic programs in various automated perimeters.

Purpose: Kinetic programs in four automated perimeters were evaluated and compared for their clinical usefulness using four simulated visual field (VF) patterns.

Methods: Using the results of conventional Goldmann manual kinetic perimetry (MKP), simulated fields with concentric contraction, a temporal residual island only, a small central island with a temporal island, and a ring scotoma were created. Four kinetic programs, Humphrey 750i Kinetic Test (Humphrey), OCULUS Twinfield 2 Kinetic Perimetry (OCULUS), OCTOPUS 900 Goldmann Kinetic Perimetry (OCTOPUS GKP), and Kowa AP-7000 Isopter (Kowa) were tested by the 4 simulated defect patterns using stimuli of V/4e, I/4e, I/3e, I/2e, and I/1e at speeds of 3 and 5°/s.
