Overview of the CSO V4 System Chart
The CSO VISION CHART V4 is a comprehensive Visual acuity testing system that provides precise, reliable results. It features advanced LCD technology for accurate, clear, and easy-to-read charts, making it an essential tool for any eye care professional. Designed for use in both clinical and research settings, the V4 offers a range of features tailored to streamline the vision testing process while maintaining the highest standards of accuracy.
Core Tests
- Visual Acuity & Contrast Sensitivity: High and low-contrast optotypes, morphoscopic tests, Pelli-Robson tests, and sine wave grating. Uses the QUEST psychovisual method for rapid acuity threshold determination.
- Refraction: Astigmatism, cross grid, Lancaster, duochrome, and balance tests.
- Binocular Vision: Worth’s test, Maddox’s, Schober’s, phorias, vergence, aniseikonia, stereo-acuity, and fixation disparity.
- Auxiliary: Low vision acuity tests (at 1 m), color blindness screening, and Amsler grids. [1]
Key Features of the CSO V4 System Chart
- Optotypes: Includes Sloan letters, Landolt rings, Tumbling E, HOTV, and children’s symbols.
- Testing Methods: Visual acuity scaling in LogMAR, Decimal, Monoyer, and Snellen (feet/meters).
- Testing Distance: Flexible calibration ranging between 3 to 6 meters depending on the specific test chart setting.
- Interactive Functions: Speeds up the testing process with automatically randomized optotypes and contrast threshold measurements.
