Light scattering in the human lens in childhood and adolescence.

The age-related increase in normal light scattering in the adult human lens has frequently been documented with Scheimpflug imaging techniques. There are only insufficient data on lens light scattering, however, from the first 2 decades of human life. After having obtained informed consent from their parents, the anterior eye segments of 26 children of both genders were documented with a Topcon SL-45 Scheimpflug camera on Kodak Tmax 400 ASA black-and-white film in 3 meridians.

Rotating slit image camera TOPCON SL 45. New developments for simultaneous image acquisition by photographic and CCD-assisted on-line documentation.

In a first approach the photographic camera part of the SL 45 B has been replaced by a CCD camera (2/3" black-and-white camera/Teli CS 3440 CCD B/W Tokyo Electronic Industry Co., Ltd.) unit thus enabling direct image acquisition and computer assisted analyses.

Improved biometry of the anterior eye segment.

In this paper, a method is presented to evaluate the true values of several optical parameters of the anterior eye segment. These are: the thicknesses of the cornea and lens, the depth of the anterior chamber and the anterior and posterior curvatures of the cornea and lens. First, a photo is taken of each patient's eye with a Topcon SL-45 Scheimpflug camera.
