Dilated fundus examination

Dilated fundus examination(DFE) is a diagnostic procedure that employs the use of mydriatic eye drops (such as tropicamide) to dilate or enlarge the pupil in order to obtain a better view of the fundus of the eye. Once the pupil is dilated, examiners often use specialized equipment such as an ophthalmoscope or fundus camera to view the inner surfaces of the eye. DFE has been found to be a more effective method for evaluation of internal ocular health than non-dilated examination. It is frequently performed by ophthalmologists and optometrists as part of an eye examination.
