ophthalmoscope

ophthalmoscope (ŏfthălˈməskōpˌ), instrument used for examining the inner structure of the eye. The device was invented by the German physiologist H. L. F. von Helmholtz in 1851. His model consisted of three plates of glass pressed together and mounted on a handle at a 45° angle. A light was placed beside the subject whose eyes were to be examined. Some light passed through the plates, but some was reflected back into the eye. The form of the instrument now in general use consists of a concave mirror and a battery-powered light source within a tubular handle. Sighting is through a single or binocular eyepiece. The ophthalmoscope is equipped with a rotating disc of lenses to permit observation of the eye at varying depths and magnifications. Examination of the eye may be enhanced by administering drugs to dilate the pupil.

In children, although it is common to demonstrate ophthalmoscopic findings such as isolated retinal microaneurysms or small unilateral hemorrhages (all of which are signs of nonproliferative diabetic retinopathy (NPDR)), it is extremely rare to find preproliferative retinopathy, proliferative retinopathy, or macular edema, regardless of the degree of metabolic control or the time of evolution of diabetes [4], with a clear tendency in our days to the decrease in the detection of retinopathy [4, 9, 10].
