The use of retinal fluorangiography techniques in the study of cerebral circulation.
Retinal fluorangiographic techniques can be employed in the study of cerebrovascular disorders in relation to the embryological, anatomic and functional affinities between the cerebral and retinal circulation. The techniques currently used have been improved by means of the computer analysis of the photographic image, thus allowing qualitative evaluations of the vascular dynamics and quantitative evaluations referred to remarkable variations. These improved techniques can be summed up as follows: equidensitometry with arbitrary colors, computerized fluorangiography for the evaluation of the vascular caliber, computer analysis of mean transit time (m.t.t.). A new type of qualitative evaluation not considering the fluorangiographic image has recently been introduced: the fluorophotometric analysis.
