Abstract
Purpose :
Objective measures of conjunctival redness while inside an environmental chamber has til now not measured. With the use of the Ora EyeCup phone we are able to get objective images of ocular redness and obtain patient self assessed redness and itching.
Methods :
During exposure in Ora’s Biocube 15 patients were given the Ora EyeCup Phone to take photos at 90 minutes into exposure. Patients were prompted to take photos by the EyeCup Phones custom software at multiple timepoints. Patients took photos of their own eye with the Ora EyeCup attached looking straight head and looking upwards while holding down their lower lid. After photos were taken at each timepoint subjects were sent to a e-diary to assess allergic symptoms including eye redness evaluated while using a mirror. Photos were then evaluated using a custom grading software on the same scale that the patient was given.
Results :
The mean patient reported redness was 3.1 on a scale from 0 to 4 with only whole integers. Mean redness from photo grading was 3.25 with the average difference between patient reported redness and photo graded redness was 0.3.
Conclusions :
These results indicate that patient self-reported redness was in good agreement with expert graders indicating that these experienced allergy patients are able to correctly assess their symptoms. Patients were successfully able to acquire high quality gradable images alleviating the need for a photo technician in the chamber and illustrating the ease of use for the Ora EyeCup phone.
