Computer-based vision screener HVF-100

Overview
The HVF-100 perimeter evaluates visual sensitivity and field extent using Goldmann-standard white-on-white stimuli with multiple stimulus sizes and luminance levels. It provides quantitative assessment of the visual field and sensitivity to contrast for diagnostic and monitoring purposes in ophthalmology.

Key features

• Goldmann-compliant white-on-white testing standard for clinical comparability
• Multiple stimulus sizes and brightness levels to map sensitivity across the field
• Comprehensive test categories: threshold, screening and special-test families with sub-tests
• Automatic OD/OS recognition to minimize operator selection errors
• Integrated automatic pupil diameter measurement during testing for correction and documentation
• Voice guidance to standardize patient instructions and improve test reliability
• Eye-tracking fixation monitoring to support reproducible results

Test programs and strategies

• Threshold test programs for quantitative sensitivity mapping
• Screening programs with selectable screening strategies
• Special test programs and related sub-tests for targeted assessments
• Blind Zone Test and Horizontal View Angle Check
• Neurological assessment programs for optic nerve, glaucoma and retinal disease evaluation and follow-up

Measurement convenience & operation

• Automatic eye recognition (OD/OS) with user prompts to reduce setup errors
• Continuous pupil size measurement during the exam for real-time correction
• Voice guidance to assist patient compliance and reduce operator intervention
• User-oriented design for repeatable clinical examinations and workflow integration

Applications

• Glaucoma diagnosis, staging and progression monitoring
• Assessment of optic nerve disorders and neuropathies
• Functional evaluation and monitoring of retinal disease
• Routine visual field screening in ophthalmic and neurological practice
