Diagnostic imaging in ophthalmology

U. Fries

Medical care and practicing has an ongoing progress with development of sophisticated diagnostic imaging. There is a new understanding of pathophysiology in many diseases. Some great hospitals spend more than 50% of there expanses for these techniques. There are mainly optical, acoustical, X-ray-, MRI and physiological techniques.

Optical imaging is conventional or digitized photo, angiography, endoscopy or scanned images in transmission or raster technology (OCT, SLO). Ultrosonography gives images of soft tissue in motion, tissue characterization and vascularisation. It becomes intervetional with capillary passing contrast enhancers. Radiological imaging developed from X-ray over tomography, angiography to CCT with spiral technology and multiplanar reconstruction as well as kinetic procedures. CCT has essential for bone imaging. Scintigraphical tests have not reached importance in ophthalmology. MRI is used for soft tissue examination , open scanners allow even interventions. Psychophysical tests (visual field) are special, this tests effort active participation of the patient.

Diagnostic imaging allows accurate and sufficient diagnoses and planing of therapy.
