Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The overall objective of this project is to develop a smartphone application and assess its acceptability and feasibility.
Fieldwork will take place during routine Tropical Data trainings and population-based prevalence surveys supported by Tropical Data.
Healthy adult volunteers in London will have photos of their conjunctivae taken to develop the app initially, with iterative improvements to the app based on image quality achieved. For fieldwork, images of the conjunctivae of children will be have photos of their conjunctivae taken with a digital single lens reflex (DSLR) camera and the newly developed smartphone app. Grading of the photos will be compared with field grading, to compare grading agreement, to assess utility for supervision, quality assurance and training purposes.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Objectives and approach:
2.1 To develop a mobile phone application to capture images of everted eyelids (conjunctivae) of children being examined as part of the Tropical Data field inter-grader agreement (IGA) test, or sampled as part of trachoma prevalence surveys.
2.2 To evaluate the quality of the mobile phone application images compared with field grading and DSLR images.
2.3 To assess the acceptability and feasibility of a mobile phone application for photographing everted eyelids (conjunctivae) from children being examined as part of the Tropical Data IGA test, or sampled as part of trachoma prevalence surveys.
2.4 To conduct a cost-consequences analysis of setting up an infrastructure for capturing and transmitting images in order to make the system economically viable.
