In the 'Tübingen Kindergarten study', an orthoptic screening program for amblyopia in three-year-olds was evaluated. In the retrospective analysis presented here, the association between a child's history--especially participation in the regular pre

UNLABELLED Specular reflections at the optical interfaces of the eye, the Purkinje reflections, are used in physiologic optics and ophthalmology for biometric measurements. To date, there is no standard in the measurement of crystalline lens radii of

This study introduces an improved computing scheme for determining eye rotation from Purkinje images I and IV. The original computing scheme systematically underestimated eye rotation. Paraxial raytracing calculations revealed that this error resulte

The {100} platelets in natural type IaA/B diamonds have been examined by spatially resolved electron-energy-loss spectroscopy and high-resolution transmission electron microscopy (HRTEM). Nitrogen concentrations were determined for platelets of four

The majority of naturally occurring gem-quality diamonds contain {100} platelet defects, the presence of which was first detected by X-ray diffraction. In this paper a detailed comparison is made, between 1·7 A resolution HRTEM lattice images of dia

A new photographic method for measuring squint angles in children and infants is presented. A photographic picture is taken from the subject, using a camera with the three flashes bulle. One flashbulle is placed vertically over the lens, two other fl
