Historical Significance: In the days before slit lamps, and before optometrists had them routinely in their consulting rooms, the binocular loupe was used for examination of the anterior eye. Slit lamps for ordinary clinical practice date back to 1911 when Alvar Gullstrand developed a rudimentary slit lamp, although the value of oblique focal illumination had been known since the early years of the 19thC. Optometrists in Australia did not adopt slit biomicroscopy until the 1960s.
