These procedures go beyond the normal routine eye examination. They will flow from patient age, symptoms and/or signs, predisposing risk factors, or findings during the routine eye examination. Many will be subsequent to the routine examination and some on another day. They all have the potential to assist in accurate diagnosis and patient management. This group includes: various forms of tonometry, various forms of fundus examination and anterior chamber evaluation.
The technique allows stereoscopic, wide-angled, high-resolution views of the fundus and overlying vitreous. Its optical principles and illumination options allow for visualisation of the fundus regardless of high ametropia, hazy ocular media, or central media opacities.
Negative powered auxiliary lenses in conjunction the slit-lamp biomicroscope can be used to view the vitreous and retina and in particular the optic disc and the macula. For clinicians with some level of binocularity a binocular direct image is viewed. The use of the slit-lamp biomicroscope allow...
All types of diagnostic contact lenses have a high minus power which produces an upright virtual image which is not laterally reversed. Contact lenses also have an advantage in that the examiner's view of the retina is not interrupted by the patient's blink reflex, although the use of contact len...
This is a technique that allows accurate evaluation of the width of the anterior chamber angle and detailed inspection of the structures within the anterior segment of the eye. The angle is not normally visible using an ophthalmoscope or slit-lamp, since light reflected by structures posterior to...
