Not medical advice

VisualFieldTracker is intended for personal tracking, observation, and testing purposes. It does not provide medical advice, diagnosis, screening, or treatment, and it is not a substitute for an examination by a qualified eye-care or healthcare professional.

Test results and comparisons

Results can be affected by viewing distance, fixation, lighting, display characteristics, browser behaviour, input method, fatigue, and other conditions. A saved test, change in marked spots, or comparability score must not be interpreted on its own as evidence that a medical condition has improved, worsened, or remained stable.

The comparability score describes technical similarity between test sessions. It is not a clinical score and has not been validated as a measure of disease progression.

Professional care

Discuss concerns about your sight or test results with an appropriate healthcare professional. Do not delay or change professional care because of information produced by this application.

If you experience sudden vision loss, a sudden change in vision, eye injury, severe eye pain, or another urgent symptom, seek urgent medical assistance through the services available in your location.

Technical limitations

Although reasonable care is taken in developing the application, uninterrupted operation and completely accurate or error-free results cannot be guaranteed. You remain responsible for using suitable equipment, following the instructions, and maintaining independent copies of any information you consider important.
