Patient-centred Smartphone AI for Protecting Vision in Macular Disease
Study Details
Study Description
Brief Summary
Macular disease is the leading cause of blindness in the UK and age-related macular degeneration must undergo monitoring to determine if an injection into the eye is required that month [required in 50% of visits] - these patients are the 'frequent fliers' within ophthalmology units, visiting specialist hospital clinics on a monthly or bi-monthly basis. This project aims to create a home-monitoring algorithm that could in the future, enable the movement of 'monitoring' of chronic eye disease into the patients' homes: remotely identifying who does need an in-person appointment, and who can safely stay away from hospital.

Detailed Description
The OKKO Health application is a CE-marked medical software application that aims to monitor visual function, track symptoms and treatment, and improve patient knowledge about their condition.
To monitor visual function, OKKO implements quick and engaging activities to assess visual function, contrast sensitivity, and hyperacuity. The aim of this is to develop the app to see if it is possible to detect changes in visual function in a timely manner. This would enable regular monitoring for disease progression and/or the response of visual function to treatments between clinical visits. Home monitoring may reveal information that may support the early diagnosis of worsening conditions and may enable a greater understanding of disease progression or stabilisation. Currently unpublished data collected using the OKKO Health app highlights its acceptability when collecting visual acuity compared to gold standard techniques used in clinical practice.
OKKO includes self-monitoring features which may result in an increased (disease) awareness including vision changes between clinic visits. OKKO offers symptom and treatment tracking functionality as well as education modules to increase literacy about the disease and treatment. These elements may improve the patient's self-efficacy, enable patient empowerment, and may increase the involvement of patients in their care and more thorough communication with ophthalmologists including shared decision-making processes. Thus, these psychological and behavioural changes may alleviate the patient's burden.

Outcome Measures
Primary Outcome Measures
- Change in visual status [12 months continuous use]
Generate an algorithm to detect a change in visual status (in particular a deterioration) in advance of in-person hospital appointment.
Secondary Outcome Measures
- Impact of the OKKO Health app on Health literacy [3-6 months of app use]
The HLS-EU-Q16, a validated questionnaire, will be used to assess Health Literacy at baseline and following 3-6 months of app use.
- Establish the real-world adoptability and cost benefit of OKKO Health use. [12 months continuous use]
Patient and clinician engagement with the OKKO Health app will be used to determine its clinical effectiveness and real world adoptability.
- To explore the correlation of varying demographic and lifestyle factors on AMD disease progression [12 months continuous use]
This will include identifying the correlation between the trend in the OKKO Health app data versus lifestyle data (this will include physical activity (steps taken, distance walked) and sleep recorded through the participants device). Correlations between health data (BMI and blood pressure) and OKKO Health trend data will also be calculated.
