The blood current of the choroid coat in the eye and wandering entrance vascular structure is improved the visualization

摘要

(57) Abstract The manner which visualizes choroid coat capillarity vascular of the eyeball which includes the fact that subtraction it does from the image which continues each image in the angiography image sequence, in the consecutive ICG angiography image. The digitized image which subtraction is done is offered at the pixel unit at the time of executing, making use of the eyeground camera (10) which was retrofitted. In order to visualize the wandering entrance nerve tube structure like the choroid coat vascular new life (CNV) satisfactorily, the eyeground camera (22) is retrofitted making use of with the analyze light polariscope (28) of the front of the polar screen (24) of the front of the illuminant (26) and video & the camera (30). As a result, it can visualize CNV the dispersion fluorescence of unnecessary it is suppressed satisfactorily to. In order to help the surgeon at the time of dealing with the wandering entrance nerve tube structure with laser optical solidification medical therapy, generating the fluorescence where two differs, it makes the eyeground camera pass (32), in order to help the fact that it decides the aim of the laser with that in order to generate the angiography figure which is superimposed accurately, synchronization doing, it can provide two illuminants (42 and 44) and two barrier filters (46) which operate.
