(e)ETDRS Auto-Guided VA Test

Simplify refractions with auto-guided visual acuity
testing strategies, smart reporting and comparative results from previous visits

Easily determine your patient’s visual acuity using the quick staircase testing method or the comprehensive ISO compliant (e)ETDRS testing protocol. Reports show detailed tabulated and graphic information which can be sent directly to EMH | EMR systems.   Instant reporting patient database, tracks trends over time on graphical and tabulated PDF reports.   The test is designed to easy alter the testing distance, especially useful when used on the moveable trolley.

This test is also suitable to be used in

  • Pre-test exam rooms
  • School screenings
  • Clinical Trials
  • Self-service vision booths

(e)ETDRS – 70 character version

The Most Comprehensive Automated Vision Test
With Smart Reporting

Phases

  • Tests Ranges Between 20/200 To 20/10
  • Screening Phase To Approximate The Subject’s VA Threshold
  • Detailed Testing Phase Creates A “Pool” Of Letters

Letter Size Pooling

  • Pool Consists Of Higher And Lower Than The Approximated Threshold
  • Upper Logmar Level – Smallest VA With 5 Letters Successfully Identified
  • Lower Logmar Level – Largest VA 0 Of 5 Letters Are Successfully Identified

Self Scoring And Reporting

  • 70 Score = All 20/10 Letters Correct And 0 Misses On Any Larger Lines
  • Report Shows Upper, Lower And Intermediary Levels
  • Report Shows Numerically And Graphically
  • Total ETDRS Score IS Calculated

Methodologies and Test Options

ETDRS

  • Letters K, R, V, And D Used Randomly For The Screening Phase
  • Followed By All The Sloan Letters For The Threshold Phase

Stair Case

  • All 10 Sloan Letters Used Randomly For Both Phases

Test Options

  • Each Eye Can Be Tested Separately And Then Together
  • Letters, Numbers, Pediatric Symbols And Global Optotypes
  • Crowding Bars On Off Option
  • 85 cd/m2 Or Normal Luminance
  • Immediate Alternate Test Distance Option
  • Tests Unique Due To Randomization Of Targets

The Wait Is Finally Over

Finally a quick way to refract, submit reports direct to EMH, and keep a complete patient history

The test is used worldwide because

  • auto-guided test strategy
  • suitable for pre-testing or self-service vision booths
  • quick stair case method
  • comprehensive (e)ETRDS protocol
  • self scored reporting
