Zrenya district case study

Introducing the Zrenya case study

In this step we introduce the Zrenya hypothetical case study, focusing on a fictional location that shares many of the common challenges faced by low and middle income countries.

Using the case study is optional, as you could instead use your own work setting. However, if you aren’t currently working in eye care, or are not sure that your local setting is appropriate, you may wish to use the case study instead.

We have provided a broad, descriptive framework for the case study. We recommend that you use it to apply and reflect on your learning from each week. It may provide the foundation from which to begin discussions with other learners and also draw a parallel to your experiences. At key points throughout the course we’ll refer back to the case study in case you decide to use it.
