Mindfulness for Central Serous Chorioretinopathy

The primary goal of this clinical trial is to test whether a mindfulness-based treatment is effective at shortening the duration of, and improving the features of, central serous chorioretinopathy in adults. Researchers will compare adults with central serous chorioretinopathy who undertake an 8 week mindfulness-based treatment course, with those who do no mindfulness, to see if mindfulness improves time to disease resolution and disease features.

The secondary goal of this clinical trial is to compare adults with central serous chorioretinopathy to adults with healthy eyes across a variety of stress-related factors, and also measure the change in some of these factors, if any, caused by mindfulness.

The questions this clinical trial aims to answer are:

* is mindfulness effective at improving the clinical course of central serous chorioretinopathy? * is a mindfulness-based treatment programme for central serous chorioretinopathy acceptable to adults with the disease? * if effective, does mindfulness alter any stress-related psychological or biological features in adults with central serous chorioretinopathy? * what are the stress-related psychological and biological features of adults with central serous chorioretinopathy, compared to adults with healthy eyes?

Participants will:

* Undertake daily mindfulness practices for 8 weeks and participate in fortnightly group sessions, or undertake no mindfulness * Visit the research clinic once every month for the first six months, and then again at 12 months, for checkups and tests
