A safe, non-contact examination of the inside of the eye and retina. The ophthalmoscope is a small handheld device. The head of this tool contains many lenses and projects light through a variably sized aperture, and is attached to a handle which serves as the power source. To perform the examination, lights in the exam room are dimmed, allowing the pupil to maximally dilate. If the pupil is still not dilated sufficiently, a topical solution may be used to aid in dilation. The patient is then asked to fixate on a target. By varying the lenses, the distance and aperture size, the doctor can survey the iris, lens, vitreous, retina and optic disc.
