Zusammenfassung

An Fundi pigmentierter Ratten wurden unter den fixen Bedingungen 300 mW, 0,2 sec Expositionszeit, 50μ spot-Durchmesser mit dem Argonlaser Photokoagulationen peripapillär ausgeführt. Die Augen wurden bis insgesamt 3 Monate nach der Intervention beobachtet, danach angiographisch und nach Enukleation fluorescenzmikroskopisch untersucht. Wir beobachteten Neovascularisationen und Farbstoffdiffusionen in den Randzonen der entstandenen Narben; die Neovaskulate gingen von der Chorioidea aus und drangen in die äußeren Netzhautschichten.

Experimental fluorescein angiographic and microscopic investigations on laser treated rat eyes

Summary

On fundi of pigmented rats, with Argon laser constantly 300 mW of power. 2 seconds exposure time and 50 microns spot diameter, coagulations have been performed. The eyes have been observed up till 3 months after the intervention, then angiographies were performed, and the following enucleated eyes have been examined with the fluorescence microscope. Neovascularizations and dye diffusions were observable mainly in the marginal zones of the arised cicatrices. The neovascularizations were starting from the choroid and penetrating into the outer retinal layers.
