INTRODUCTION: To evaluate the effect of 1000-cSt silicone oil (SO) which is used for pars plana vitrectomy (PPV) surgery on subfoveal choroidal thickness
METHODS: In this retrospective study, 20 eyes of 20 patients who had undergone PPV and SO injection surgery for macula-off rhegmatogenous retinal detachment were included in the study. Complete ophthalmologic examinations were performed before the surgery, 1 month, 3 months after PPV and 2 months after silicone oil removal. After 1 month following PPV and SO injection and 2 months following silicone oil removal subfoveal choroidal thickness was evaluated by EDI (enhanced depth imaging) mode of spectral domain optical coherence tomography.


RESULTS: Subfoveal choroidal thickness measurements decreased statistically significantly at 2 months after silicone oil removal compared to the first month of PPV and SO injection. The mean subfoveal choroidal thickness was 284.2 ± 54.2 µm at 1 month after PPV and SO injection while it was 258.8 ± 52.8 µm at 2 months after SO removal (p <0.001).
DISCUSSION AND CONCLUSION: Following removal of SO subfoveal choroidal thickness measurements decreased; therefore changes of subfoveal choroidal thickness measurements may be a parameter for timing of SO removal.
