To evaluate possibles changes in ocular perfusion pressure (OPP) through the analysis of variation in oximeter perfusion parameters observed during the silicone oil removal time.
Therapeutic study - 30 cases with retinal detachment and giant retinal tear submited to silicone oil removal.
Analysed 30 patients with retinal detachment and giant retinal tear submitted to silicone oil removal surgery. Visual acuity after surgery was related with the changes of oximeter perfusion parameters observed during the silicone oil removal time and the ocular perfusion pressure was estimated by these parameters obtained from this study.
Some patients with retinal detachment and giant retinal tear had a visual acuity decreased and presented central or paracentral absolute scotomas after the silicone oil removal. A significant reduction in the oximeter perfusion parameters was observed during the time of silicone oil removal that may result in an ischemic optical nerve involvement.
A faster silicone oil removal that was obtained with the use of larger gauge trocars reduced the time and the variations of the oximeter perfusion parameters analyzed during the silicone oil removal in these cases.
