Purpose: To compare the modified signal-to-noise ratio (SNR*) of multifocal visual evoked potential (mfVEP) responses elicited by a cathode ray tube (CRT) and liquid crystal display (LCD) monitor in normal subjects.
Methods: An LCD monitor and CRT monitor were luminance and contrast matched. Luminance stability and the effect of viewing angle on luminance and contrast was measured for both screens.
Background: To present a case of melanoma-associated retinopathy (MAR) which manifested 26 months prior to a formal diagnosis of melanoma.
Methods: Case report.
Results: A 72-year-old female presented with bilateral continuous photopsia consistent with MAR of 7-months duration.
