Inspection Goldman lens
Examination with the Goldmann Lens
(This test is part of the initial diagnostic work-up)
The Goldmann lens is named after the researcher who introduced it in 1948. This flat lens with a system of three mirrors has become widely used in biomicroscopy and laser coagulation of the anterior segment of the eye and the retina. Using this lens, the posterior pole of the eye can also be observed in an upright (non-inverted) image through the central part of the lens.
Unlike the standard procedure, biomicroscopy of the eye with the Goldmann lens makes it possible to examine in detail the condition of the posterior wall of the eyeball, even with a constricted pupil. A unique advantage of this method is the ability to carefully and thoroughly assess all areas of the fundus, including the peripheral ones. This is achieved with the help of special mirrors built into the Goldmann lens, which reflect images from the periphery of the fundus and bring them into the ophthalmologist’s field of view. These mirrors are called gonioscopic mirrors. Each of the three mirrors is designed to examine different parts of the eye: the small one is used to assess the anterior chamber angle and the extreme retinal periphery, the medium one – to observe the peripheral retinal regions anterior to the equator, and the large one – to examine the equatorial fundus and mid-peripheral areas.
Examination of the eye with the Goldmann lens allows the detection of dystrophic changes and retinal detachment when evaluating patients with high myopia.
