Eye examination with the aid of a slit lamp. Side view of a slit lamp machine. Cataract in human eye: magnified view seen on examination with the slit lamp. In ophthalmology and optometry, a slit lamp is an instrument consisting of a high-intensity light source that can be focused to shine a thin sheet of light into the eye.
He improved and developed in collaboration with Haag-Streit AG (Aktiengesellschaft) several ophthalmic instruments, including: slit lamp, [4] colorimeter, Goldmann's perimeter (1945 development), [4] Goldmann's tonometer, [4] Goldmann's indirect goniolens, Goldmann-Weekers Dark Adaptometer™, [5] and; fluorophotometer.
On February 28, 2018, Metall Zug acquired control of Köniz, Switzerland-based Haag Streit Holding AG. [8] Haag Streit comprised more than 20 companies with about 900 employees and develops products for the ophthalmology (diagnostics, surgical microscopy), pulmonology , and optics fields; [ 9 ] the company was acquired to form Metall Zug's ...
The anterior segment or anterior cavity [1] is the front third of the eye that includes the structures in front of the vitreous humour: the cornea, iris, ciliary body, and lens. [2] [3] Within the anterior segment are two fluid-filled spaces: the anterior chamber between the posterior surface of the cornea (i.e. the corneal endothelium) and the ...
Progressive segmented Frame (PsF, sF, SF) is a scheme designed to acquire, store, modify, and distribute progressive scan video using interlaced equipment.. With PsF, a progressive frame is divided into two segments, with the odd lines in one segment and the even lines in the other segment.
Haag (1958) [8] and David Ruelle (1962) [9] have presented the Haag–Ruelle scattering theory, which deals with asymptotic free states and thereby serves to formalize some of the assumptions needed for the LSZ reduction formula. [10] These techniques, however, cannot be applied to massless particles and have unsolved issues with bound states.
[9] [10] A fundus camera provides an upright, magnified view of the fundus. A typical camera views 30 to 50° of retinal area, with a magnification of 2.5x, and allows some modification of this relationship through zoom or auxiliary lenses from 15°, which provides 5x magnification, to 140° with a wide angle lens, which minifies the image by ...
The globe of the eye, or bulbus oculi, is the frontmost sensory organ of the human ocular system, going from the cornea at the front, to the anterior part of the optic nerve at the back. More simply, the eyeball itself, as well as the ganglion cells in the retina that eventually transmit visual signals through the optic nerve. [ 1 ]
