title: Observation of injected fluorescein diffusion after laser treatment of cat fundi. An experimental study with angiography and microscopy.
abstract: Argon laser coagulations with a power of 100 mW and 300 mW, exposure time 0.02 and 0.02 sec, and constant spot size of 100 microns were applied on normal cat fundi. From 1 and 2 hrs to 7 days after the coagulation, the treated eyes were observed angiographically and by fluorescence microscopy after dye injection; freeze dried eyes were examined under a fluorescence microscope. Abnormal dye leakages originated from the chorid and from retinal vessels were detected in the specimens examined within 72 hrs after the coagulation.
