RESUMO
In the case of small breaks, the operating microscope and slit lamp are of great help in retinal detachment surgery. The use of an adequate peripheral fundus contact lens is necessary. The technique to be followed is described and its advantages and disadvantages are discussed.

Xenon arc photocoagulation of the fundus of pigmented rabbits resulted in no corneal endothelial cell damage when the experiment was designed to minimize corneal temperature rise by frequent topical instillations of ophthalmic irrigating solution.

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.
