The aim of the current study is the efficiency assessment of C3F8 gas usage in posterior vitrectomies in patients having retinal detachment of different etiologies with presence of proliferative vitreoretinopathies and retinal tears. 34 patients have undergone posterior vitrectomy with the usage of perfluoropropane C3F8 gas for providing internal tamponade. Total attachment of retina has been attached in all 34 cases and C3F8 gas has been injected in each eye. The most frequent complications that have been revealed after the usage of C3F8 gas and their management are reflected in the article. Thus, we came to a conclusion that vitrectomy in combination with episcleral buckling, transvitreal drainage of subretinal liquid, diode endolaser coagulation of retina and internal tamponade with C3F8 gas is effective and pathogenetikally proved method for treatment of rhegmatogenous retinal detachments complicated with severe vitreoretinopathies. The achievement of perfect anatomical results depends on manifestation degree of proliferative vitreoretinopathy.
