Hemorrhage and retinal perforation are two sight-threatening complications associated with techniques employed to drain subretinal fluid in rhegmatogenous retinal detachment. We hypothesized that the carbon dioxide (CO/sub 2/) laser would reduce these complications because of its cauterizing action and high absorption in water. The CO/sub 2/ laser was compared with a conventional technique of using a penetrating diathermy electrode to drain subretinal fluid in rabbits with experimentally detached retinas. No hemorrhage occurred in 223 drainage trials using the CO/sub 2/ laser, whereas hemorrhage occurred in 21 (4.8%) of 434 trials using the penetrating diathermy electrode. Furthermore, a depth of saline of only 45 microns protected the retina from perforation at CO/sub 2/ laser dose adequate for drainage. These results indicate that further evaluation of the CO/sub 2/ laser in treating human retinal detachment is warranted.
