Finding causes – solving visual problems – ensuring better care

Switch directly to the BTSO app

The web-based BTSO learning app offers an innovative and practice-orientated solution: a digital tool for simplified access to knowledge and tools. It teaches professionals how to recognise binocular abnormalities more quickly and how to treat them appropriately.

BTSO is a non-profit project that invests its income in further development, research and improvement.

Free trial phase for 4 weeks – immediately available with all functions but without data storage.
The paid version allows all data to be stored and is activated when you take part in a course (online or in person). Costs 33 CHF / month. The minimum term is one year.

Vision-related problems are common.

  • 56% vision-related problems (e.g. headaches or tired eyes) of all patients aged between 18 and 38 years n= 1679 in five vision centers (Montés-Micó, 2001).
  • 46% asthenopic problems in computer users n= 419 (Bhanderi, Choudhary, & Doshi, 2008).

Classification allows a targeted approach to solving the problems.

  • 32% can potentially benefit from the classification
    (García-Muñoz, Carbonell-Bonete, Cantó-Cerdán, & Cacho-Martínez, 2016), and (Hussaindeen et al., 2017).


Easy to get started with the minimal test battery (3 tests)

Detect vision problems and their causes quickly and easily: With just three measurements, it is possible to determine very specifically whether binocular vision or accommodation is abnormal. The BTSO learning app shows how a classification is made.

Schoolchildren can also be quickly screened for vision problems using the minimal test battery.

Features

  • Quick and easy. The test sequence takes about 6 minutes, the evaluation 1-2 minutes.
  • Can be used during the eye test or in quick mode after the eye test.
  • Can be used from school age. User guidance through all steps of the measurements with information displays.
  • Evaluation graphic to make all parameters visible at a glance and to show whether they are within the normal range or not based on their position.
