Ultrawide field imaging of the retina is a rapidly developing technology. The purpose of this study was to evaluate the concordance between ophthalmoscopy and wide field image reading both performed by an ophthalmologist.
A prospective two center study was performed at two university hospitals (Lille, Reims) from January 2010 to Novembre 2014. The first eligible patient presenting at the outpatient every working day was included. A wide field imaging optomap ® (optos) was performed by a nurse or an orthoptist before the medical examination. Indirect slit lamp ophthalmoscopy was performed, with or without dilated pupils according to the clinical situation. Then the image lecture was performed by the ophthalmologist. In both cases, the characteristics of the optic disc, the vessel and the retina were noted.
901 patients were included in the study. A highly substantial agreement between both examination methods was found when the overall results were considered k=0.88 [0.85-0.90]. When comparing the agreement with retinal findings, (k= 0.83 [0.80-0.86]), optic disc findings (k=0.89 [0.86-0.92]) and vessel analysis (k=0.84 [0.79-0.89]), it was highly substantial. An abnormal finding was detected on ultrawide field image analysis only and was missed with ophthalmoscopy in 42 eyes. In 12 eyes, an abnormal finding was seen with ophthalmoscopy and was not detected on ultrawide field imaging.
There appears to be an excellent agreement between ultrawide field image analysis and ophthalmoscopy. However the false negative rate appears to be higher with ophthalmoscopy.
