Contrast sensitivity functions (CSF) provide a better measure of visual function than traditional acuity tests. The use of CSFs with cataract and contact lens patients as well as with patients suspected to have glaucoma or retrobulbar neuritis is discussed. Various methods for determining the CSF are discussed, with the conclusion that the newly developed Arden plates are best for use in clinical practice.

In all, 55 eyes of 55 patients were examined prospectively in random order with the Humphrey field analyzer [central field 76 points, full threshold strategy, single-stimulus presentation, response-button control (HFA 1); central field 76 points, defect-depth strategy, response-button control (HFA 2)] and the Dicon TKS-4000 [central field 76 points, defect-depth strategy, multiple-stimulus presentation, response-button control (DIC 1); central field 76 points, defect-depth strategy, multiple-stimulus presentation, voice control (DIC 2)]. Some 26 patients (47%) had glaucomatous field defects, 7 patients (13%) had lesions of the visual pathway, 5 patients (9%) had normal fields. The other 17 patients (31%) had field defects due to vascular lesions of the retina or the optic nerve, retrobulbar neuritis, cataract, dysthyroid optic neuropathy, disorders of the macula, or human immunodeficiency virus (HIV) retinopathy. The mean testing time for the whole study population was 5.2 +/- 2.7 min for DIC 1. The difference from the mean testing time for HFA 2 (6.4 +/- 2.7 min) is statistically significant (p = 0.0013). DIC 2 reduces the mean testing time to 4.9 +/- 2.6 min. The difference from DIC 1 is not statistically significant (p = 0.8110). A multiple-stimulus presentation and voice control seem to be useful methods to reduce the testing time in automated perimetry without a loss of accuracy. Voice control, as used in the DICON TKS 4000, still has to be improved, however.

Patient was followed up over the course of 30 years. In 1978, after severe systemic infection followed by fever, pulmonary edema, and numerous neurological manifestations, patient was differentially diagnosed with apoplectic form of multiple sclerosis (MS), which was confirmed a year later via neurological and MRI findings. Approximately 20 years following the initial attack, sarcoidosis was diagnosed during the regular preoperative procedures required for cataract surgery. As consequence of lower immune system, infectious granulomatosis in form of pulmonary tuberculosis developed. Ophthalmological findings revealed bilateral retrobulbar neuritis (RBN) approximately six years after initial attack. This developed into total uveitis with retinal periphlebitis and anterior granulomatous uveitis-all of which are clinically similar in both MS and sarcoidosis.
