Smartphone App for Taking Images of Conjunctivae

Summary

Trachomatous inflammation-follicular (TF) is diagnosed by looking for clinical signs of infection of everted eyelids (conjunctivae) of children.

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.
