Retinal blood flow in senile macular degeneration. A Blue Field study [STUDIO DEL MICROCIRCOLO RETINICO CON LA TECNICA DEL BLUE FIELD IN PAZIENTI AFFETTI DA DEGENERAZIONE MACULARE SENILE]
No full textThe technique of the "Blue Field" simulation is based on an endo-optic phenomenon obtained by means of gazing a dark-blue and uniform light, of a 430 nanometers wave lenght. This phenomenon is due to the presence, in the retinal capillaries of 7-10 micrometers diameter, of red blood cells with some leucocytes among them, while the red blood cells do not allow the light to reach the retinal photoreceptors, the leucocytes are crossed by it, so being perceived as shining bodies.In order to obtain that, the patient is request to compare and balance the number of the perceived leucocytes,their velocity and rythm, by means of simulating with the help of a computer the presence of the leucocytes in a video display. This procedure is repeated five times.The Authors report the results obtained by using this technique in a group of 10 patients suffering from senile macular degeneration in prediskiform stage.In this way we pointed out that the circulation in the macular retinal capillaries in this patients is changed, in relation to the alterations of the visus from near

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
