5 mm creates a condition known as ‘broad beam’ illumination, whereby the width of the beam is greater than the depth of the cornea (effectively creating a parallelepiped which is turned on its side). Whilst scanning the external ocular surface, a low-to-medium magnification is initially chosen and the magnification is increased if any area of interest needs to be examined more closely. 8). This permits assessment of the location, width and height of any object within the cornea or adjacent structures.
Since this book is concerned with the assessment of ocular complications of contact lens wear, the discussion that follows will relate primarily to the use of the slit lamp biomicroscope in examining the anterior ocular structures. unlocked to allow the focal illumination to be directed away from the focal point of the viewing system, which is an essential requirement for some observation techniques, such as ‘sclerotic scatter’ (see below). The mechanically linked illumination and observation systems are always moved simultaneously – up and down with a height con trol, and focusing (in and out) and lateral (side to side) movements with a joystick.
16 The Topcon Specular Microscope SP3000P. ) These instruments are primarily used to view and photograph the corneal endothelium and to monitor its morphology. By direct viewing with the specular microscope, an overall impression of the condition of the endothelium can be established immediately. In addition, some of these instruments allow corneal thickness to be determined by measuring the distance between the epithelium and endothelium. Typically, the features looked for are the regularity of the endothelial mosaic, the size of the individual cells, the presence of intracellular vacuoles, and abnormal features such as corneal guttae and keratic precipitates.
