Troca fluido-gasosa pós-vitrectomia via “pars plana”

Fluid gas exchange after “pars plana” vitrectomy

RESUMO

Foram observados 30 pacientes com indicação de troca fluido-gasosa pós-vitrectomia via "pars plana”. As indicações incluíram proliferação vítreo-retiniana (PVR), rotura gigante, descolamento de retina regmatogênico recorrente, trauma perfurante e descolamento tracional da retina com hemorragia vítrea associadas à retinopatia diabética proliferativa. Os pacientes foram acompanhados por um período de três a 36 meses. Os olhos foram tratados com uma mistura de ar e hexafluoreto de enxofre em concentrações variando até 40% de SF6, sendo observados no primeiro dia pós-troca níveis pressóricos tanto mais elevados quanto maior a concentração do SF6. A retina se manteve aplicada em 53% dos casos, sendo que no grupo de proliferação vítreo-retiniana o resultado foi melhor quando associamos a fotocoagulação com laser de argônio.

SUMMARY

We describe the technique, indications, complications and results of pars plana vitrectomy with subsequent fluid-gas exchange associated with laser photocoagulation for the management of complicated vitreore-tinal disease. lndications included proliferative vitreoretinopathy, giant retinal tear, recurrent rhegmatogenous retinal detachment, perfurating trauma and tracional detachment with vitreous hemorrhage associated with proliferative diabetic retinopathy. Eyes treated with a mixture of air and SF6 demonstred a higher intraocular pressure on the first post exchange day according with the higher SF6 concentration. In 5% of the cases the retina was reattached and the association of fluid-gas exchange and argon laser photocoagulation appears to be more effective in the cases of PVR
