Contrast sensitivity testing in clinical practice.

Contrast sensitivity testing in clinical practice.

A survey of ophthalmic publications carried out using the Medline database revealed that during 1983 the search terms contrast and sensitivity appeared in immediate conjunction within the indexing fields of 74 publications. By 1993, this figure had risen to 325. Though a search conducted in this manner would by no means retrieve all the relevant publications, this fourfold increase would sugges...

The role of contrast sensitivity charts and contrast letter charts in clinical practice

Russell L Woods PhD MBCO FAA0 and Practitioners frequently make clinical decisions based on changes in visual acuity. HowJoanne M Wood PhD MBCO FAA0 ever, acuity is recognised to be only one aspect of visual performance. In recent years, School of Optometry, Queensland Univera number of clinical chart-based tests which measure different aspects of vision based sity of Technology on contrast sen...

Optimizing Contrast Sensitivity Perimetry for Clinical Use

Perimetric testing is used clinically to detect visual field abnormalities and to monitor changes during the course of management. Conventional automated perimetry (CAP), which employs small (0.43 degree) targets (Fig. 1), is hampered by high test-retest variability. Consequently, many tests are required in order to determine whether a patient is stable or progressing. Decreasing test-retest va...

Laboratory Genetic Testing in Clinical Practice 2016

The genetic testing in various clinical conditions emerges to have an important role in both diagnosis and treatment. Recently, a revolution in genomic technologies from the first-generation Sanger method to next-generation high through-put sequencing and microarrays has occurred. All of these technologies have been widely applied for genome, exome, transcriptome sequencing, and epigenomics. Th...
