To determine the variation in diagnosis and management of retinopathy of prematurity (ROP) among ROP experts presented with images obtained using an iPhone 5 camera.
Fundoscopic images of 11 patients (22 eyes) with ROP were obtained using a 40 diopter (D) lens and the video application of the iPhone 5. Three ROP experts were asked to review the digital images and were masked as to the clinical diagnosis made by indirect ophthalmoscopy. The following parameters were recorded: the presence or absence of Plus/Pre-Plus disease, Zone, Stage and the management plan. Agreement between the three ROP experts was tested for each parameter using intraclass correlation coefficients (ICCs) in SPSS.
Interexpert agreement between was significant for Plus disease (ICC = 1.0) and treatment requiring ROP (ICC = 1.0). Identification of Zone and Stage were not significant.
There is significant agreement in identifying Plus Disease when interpreting images obtained by using the iPhone 5 digital camera and a 40D lens. Using the iPhone 5 and a 40D lens may prove to be a low cost method of obtaining images for ROP diagnosis and management.
