Abstract
PURPOSE: Retinal detachment after Nd: YAG laser vitreolysis is rarely reported. The pathogenic role of Nd: YAG laser is analyzed from 3 cases of severe retinal detachment. METHODS: Three men aged (40 to 59 years old) had one or more risk factors for retinal detachment: myopia, complicated cataract surgery, personal or family history of retinal detachment. Nd: YAG laser treatment onto vitreous strand was performed because of: retinal traction, repeated vitreous hemorrhage, anterior vitreous strand in a aphakic patient with cystoid macular edema. Within six weeks following Nd: YAG laser vitreolysis, severe retinal detachment with several tears occurred, complicated with proliferative vitreoretinopathy in two patients, and with choroidal hemorrhage in one. In two cases, several surgical procedures with silicon oil were required and visual acuity remained under 20/1000. In the last case retinal reattachment was obtained with scleral buckling and cryopexy, the patient recovered a visual acuity of 20/100 with a macular pucker. DISCUSSION: Retinal detachment occurred shortly after laser YAG vitreolysis. We assumed Nd: YAG laser was possibly responsible and investigated the possible mechanisms: direct retinal tear, vitreous strand traction, side effect of intraocular shock wave. CONCLUSION: Nd: YAG laser vitreolysis seems to be able to cause retinal detachment. Its use is therefore not recommended, particularly in patients at risk, especially since the efficacy of this treatment has not been proved.
評： YAG vitreolysis 亦可能造成retinal detachment，使用上仍需小心
