We found a moderate correlation in controls between white computer averaged b-wave amplitude and b-wave obtained with other wavelengths (over 600 nm red, over 550 nm orange, and under 500 nm blue), in scotopic (white\/orange r = 0.41, P &lt; 0.05; white\/red r = 0.45, P &lt; 0.05; white\/blue r = 0.48, P &lt; 0.02) and photopic conditions (white\/orange r = 0.6, P &lt; 0.01). For P.S.H. there was a highly significant correlation between white and all wavelengths in photopic (white\/orange r = 1, white\/red r = 0.96, P &lt; 0.0001) and scotopic conditions (white\/orange r = 0.97, P &lt; 0.0001; white\/red r = 0.96, P &lt; 0.0001; white\/blue r = 0.96). In vasculitis, as in controls, we found no white\/red correlation and only in vasculitis we could not find a scotopic white\/blue correlation. We conclude that these situations are electrophysiologically different. The closer correlation in P.S.H. suggests more efficient phototransduction and in C.I.R.V. there may also be a rod-selective dysfunction.<\/jats:p>","DOI":"10.1177\/112067219200200404","type":"journal-article","created":{"date-parts":[[2018,4,16]],"date-time":"2018-04-16T11:08:22Z","timestamp":1523876902000},"page":"179-189","source":"Crossref","is-referenced-by-count":2,"title":["Electrophysiology in Pseudohistoplasmosis and Chronic Idiopathic Retinal Vasculitis"],"prefix":"10.1177","volume":"2","author":[{"given":"L.","family":"Pereira-Neves","sequence":"first","affiliation":[{"name":"Lisbon Institute of Ophthalmology Lisbon Faculty of Medicine, Lisbon - Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.","family":"Ribeiro-Da-Silva","sequence":"additional","affiliation":[{"name":"Lisbon Institute of Ophthalmology Lisbon Faculty of Medicine, Lisbon - Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1992,10,1]]},"reference":[{"key":"bibr1-112067219200200404","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9394(73)90573-4"},{"key":"bibr2-112067219200200404","doi-asserted-by":"publisher","DOI":"10.1001\/archopht.1984.01040031440019"},{"issue":"5","key":"bibr3-112067219200200404","first-page":"349","volume":"2","author":"Saraux H.","year":"1979","journal-title":"J Fr Ophtalmol"},{"key":"bibr4-112067219200200404","first-page":"654","volume":"9","author":"Saraux H.","year":"1986","journal-title":"J Fr Ophtalmol"},{"key":"bibr5-112067219200200404","first-page":"202","volume-title":"Clinical methods in uveitis, fourth Sloan symposium on uveitis.","author":"Gass J.D.M.","year":"1968"},{"key":"bibr6-112067219200200404","unstructured":"GassJ.D.M.
