Publisher Summary This chapter provides an overview on slit-lamp examination, in which objects within the rays of the beam are examined under magnification. It discusses the techniques of slit-lamp examination, such as diffuse illumination, direct focal illumination, retro-illumination, specular reflection, and sclerotic scatter.

All opthalmologists realize the value of the slit lamp, but the cost makes many forego its use. The inexpensive lamp described hereafter has given good service in my office. THEORY OF THE SLIT LAMP The slit lamp sold commercially consists essentially of five parts : a concentrated filament lamp, a condenser, a slit, an objective lens and a microscope.

The slit lamp was invented at the beginning of the 20th century to visualise the anterior and middle segments of the eye more accurately.1 2 A major advance in its use in clinical practice was the introduction of strong plus lenses (eg, +60, +78, +90 D) to allow biomicroscopy of the fundus.3 I present an extended use of the slit lamp, enabling it to ...

Slit-Lamp Examination of the Fundus
Archives of Ophthalmology, 1958Owing to the great interest in retinal detachment surgery at the present time, there are frequent reports of the best manner in which one should examine the fundus ophthalmoscopically. Proponents of indirect ophthalmoscopy vigorously support this as a new method, which as a matter of fact was first proposed and practiced by Sichel in 1885 and ...

Wilhelm von Zehender and the court mechanic Heinrich Westien constructed the first binocular microscope in 1887, calling it a “corneal loupe” (von Zehender and Westien 1887). It was fitted with an objective and ocular providing tenfold magnification so that the anterior segments of the eye could be viewed stereoscopically. Dr. von Zehender also carried

In the August 1932 issue of theArchivesI described an illuminated loupe. 1 In this article I stated : One of the difficulties confronting the ophthalmologist in the use of the monocular loupe is in obtaining a sufficient amount of condensed light at a suitable focal distance.
