NCT07767058

Brief Summary

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

Outcome Measures

Primary Outcomes (1)

  • Time to disease resolution (days), defined as the absence of foveal centrepoint subretinal fluid (SRF) on optical coherence tomography (OCT) imaging, without treatment with either photodynamic therapy (PDT) or laser.

    From enrolment until 6 months

Secondary Outcomes (36)

  • Change in best corrected visual acuity (Early Treatment Diabetic Retinopathy Study [ETDRS] letter score)

    From baseline to month 2, 6 and 12

  • Change in 'real world' visual acuity (VA; ETDRS letter score), measured with the patient's usual refractive correction

    From baseline to month 2, 6 and 12

  • Change in low luminance visual acuity (ETDRS letter score)

    From baseline to month 2, 6 and 12

  • Change in maximum subretinal fluid (SRF) height (µm) at any given macular location

    From baseline to month 2, 6 and 12

  • Change in central 1mm subfield thickness (µm)

    From baseline to month 2, 6 and 12

  • +31 more secondary outcomes

Other Outcomes (35)

  • Macular Treatment Satisfaction Questionnaire score (MacTSQ; composite score)

    From baseline to month 2

  • Descriptive feedback from participants on their experience of the intervention

    From baseline to month 2

  • Number of participants recruited per site per month

    From the time of green lighting of the first study site, up until the point at which the last patient is recruited on to the study, projected to be approximately 45 months.

  • +32 more other outcomes

Study Arms (3)

Mindfulness

EXPERIMENTAL

The intervention consists of consists of an 8-week self-directed daily mindfulness course, combined with fortnightly group mindfulness sessions that participants are encouraged to join from enrolment up until their month 6 follow up visit. The intervention has been designed specifically for this trial and is tailored to central serous chorioretinopathy. Participants will be given a set of video and audio guidance for daily mindfulness-based practices, for a total duration of 8 weeks, alongside a 'road map' of the intervention to prompt them to which practices to use on each day. Daily practices will include body scan exercises, breathing exercises, mindful movement, mindful moments in daily life exercises, and mindfulness in response to stress exercises. Practices will range from 5 - 20 minutes' duration. Participants will be invited to join fortnightly group mindfulness calls, held via Microsoft Teams, for the first six months of their involvement in the trial.

Behavioral: Mindfulness

No mindfulness

NO INTERVENTION

This is the control group. They will not undertake daily mindfulness practices or fortnightly group sessions.

No central serous chorioretinopathy (healthy eyes)

NO INTERVENTION

This arm is the case-control comparator, consisting of age- and sex-matched adults with no central serous chorioretinopathy or other sight-threatening eye conditions

Interventions

MindfulnessBEHAVIORAL

The intervention is an 8 week course of daily mindfulness practices, accompanied by 6 months of fortnightly group sessions. Two introductory videos will explain about central serous chorioretinopathy, mindfulness and the links both have to stress-related factors, and outline the structure of the mindfulness course. Participants will be given a set of video and audio files that will guide them through daily mindfulness practices, for a total duration of 8 weeks. Daily practices will include body scan exercises, breathing exercises, mindful movement, mindful moments in daily life exercises, and mindfulness in response to stress exercises. Individual practices will range from 5 - 20 minutes' duration. There will also be fortnightly group mindfulness sessions, facilitated by a mindfulness coach and with an Ophthalmologist present. They will include guided mindfulness practices and free discussion time for participants to share their experience of the intervention and ask questions.

Intervention Model
PARALLEL
Model Details: This trial contains two models - an interventional model and a case-control model. The primary model is a parallel interventional model involving two arms (intervention and control) of participants, both of which have central serous chorioretinopathy. The secondary model is a case control model involving the two groups of participants with central serous chorioretinopathy, and another group of participants with healthy eyes. As such, the investigators have entered 3 total arms to the trial in the section below, but only two of these arms are part of the interventional element of the trial.
