Scientific title
Implementation of Compliance Improvement for Amblyopia Prevention: further training course about compliance, an effective information programme and direct referral by child health care centres, primary with orthoptists in foreign and low-SES (socio-economic status) neighbourhoods
Acronym
ICI-AP
Study hypothesis
Orthoptists work more effectually by using an improved compliance enhanced programme and a training course on compliance.
Ethics approval
Ethics approval received from the local medical ethics committee
Study design

Condition
Amblyopia
Intervention
At end of year one the orthoptist will receive a three-days training course on compliance with amblyopia prevention. Strategies and techniques to reduce non-compliance are given during the training.
All children included in the first year are the control group: receive standard orthoptic care.
All children included in the second year is the intervention group: receive the improved educational cartoon story together with a calendar and reward stickers, and a one-page information sheet for the parents. The cartoon is designed as a picture story, without text and is designed from a childs perspective.

Primary outcome measures
Whether the orthoptists work is effectual, based on measurements (i.e. questionnaires) at the start of the study, before and after the training course, and at the end of the second year.
Secondary outcome measures
The electronic occlusion measurements for compliance (actual occlusion time/prescribed occlusion time), the fraction realised Child Health Care centre referrals and the overall acuity improvement will be determined.
