Evaluation of safety of double tamponade of vitreous cavity in surgical treatment of retinal detachment

The purpose of the study is to assess the safety of retinal detachment surgery employing double endotamponade with petfluorocarbon liquid (PFCL) and silicone oil for 30 days. Inclusion criteria: retinal detachment with retinal breaks located in both upper and lower retina and/or with residual severe proliferative vitreoretinopathy. In the study group (26 eyes) the surgery was finished with double tamponade with PFCL and silicone oil. In the control group (20 eyes) the surgery was finished with silicone oil tamponade. Tamponade agents were removed 1 month later. Examinations included optical coherence tomography (OCT) and microperimetry along with standard eye examination. Retinal reattachment by means of one surgical procedure was achieved in 81 % in the study group and in 65% in the control group. There was no significant difference in BCVA between the two groups. OCT data analysis showed no significant differences between the groups in the thickness of outer and inner nuclear layers. Microperimetry detected no significant differences in light sensitivity between the groups. Double endotamponade with PFCL and silicone oil seems to be a safe method for the treatment of complicated retinal detachments. [PUBLICATION ABSTRACT]
