Greek ophthalmogist Alexin Tranta (1867-1961) made the first observations of the anterior angle using ophthalmoscopy and scleral indentation publishing his observations from 1907 up to 1928. Austrian ophthalmologist Maximillian Salzman made observations also using a scleral contact lens. Gullstrand devised the slit lamp, the first being produced by Zeiss in 1920 and he developed the design of the contact lens for gonioscopy. Tronosco reported on the angle in various forms of glaucoma and developed the binocular gonioscope in 1941. See Dellaporta A. Historical notes on gonioscopy. Surv Ophth 1975; 20: 137-149
