“…It is important to realize that prolonged latencies and a reduced PRVEP amplitude are not specific for maculo- pathy or subclinical alterations of the posterior pole of the eye (Johnson et al 1987;Lennerstrand 1982), but that usually PRVEP examination is indicated for pathology of the more central parts of the optical visual pathway (Bemelmans et al 1995). Two investigations providing additional information about maculopathy in this context are the focal cone ERG and the pattern reversal ERG.…”

ABSTRACT.Purpose: To investigate whether the pattern reversal visual evoked potential can be useful in the diagnosis and management of macular hole patients. Methods: The pattern reversal visual evoked potential was measured in 66 patients with a macular hole and in 43 healthy control subjects. Check sizes of 34: 17' and 10' were applied. Results: Results showed that, for the check sizes of 34: 17' and 10: eyes with a macular hole had significantly prolonged NSO and PlOO latencies and a significantly reduced PlOO amplitude as compared to their fellow eyes. Furthermore, for the 10' check size, the fellow eyes appeared to have a significantly reduced PlOO amplitude in comparison with the control eyes, whereas NSO and PlOO latencies of the fellow eyes of the macular hole patients were not prolonged. Conclusion: Significant pattern reversal visual evoked potential alterations were shown in eyes with macular holes and fellow eyes for small check sizes.

“…Visual evoked potentials are abnormal at the onset of ON or shortly afterwards in the majority of patients (Frederikssen, 1997;Fulgente et al, 1996). A recent study of 105 ON patients (Bemelmans et al, 1995), concluded that the best recordings can be obtained using a 10°check size. In addition, the P80 waveform peak appeared to be more sensitive than the NIOO to the presence of MS. Latency delays and amplitude reductions in MS patients are often larger if chromatic rather than luminance stimuli are used (Porciatti and Sartucci, 1996).…”

ABSTRACT.Purpose: The evaluation of the anomaloscope slope quotient in patients with acquired colour vision deficiency. Methods: Two patients with Stargardt's disease in combination with protanomaly and deuteranomaly, respectively, were selected and also 3 patients with a presumed dominant optic atrophy of the protan type. The anomaloscope examination was performed according to the Linksz procedure. The luminance fall was calculated as the slope quotient SQ:Y units luminance fall per X units width of the matching range. Results: The SQ of the 2 Stargardt patients was steeper than the SQ of congenital colour vision defectives, especially at the red end of the anomaloscope green-red mixture scale, indicating pathologic scotopization superimposed on the congenital deficiency. In optic atrophy of the protan type the SQ was flatter than in congenital deficiency, indicating that this deficiency has nothing to do with congenital protan deficiency. Conclusion: Calculation of the slope quotient SQ is helpful for the diagnosis of acquired colour vision deficiency, especially when the subject also has a congenital colour vision deficiency or is supposed to have such a deficiency.
