2M.D. Professor, Baskent University Faculty of Medicine, Department of Ophthalmology, Ankara/TURKEY Purpose: To investigate subfoveal choroidal thickness (SCT) between pars-plana vitrectomy (PPV)+laserphotocpagulation+C3F8 and PPV+ laserphotocoagulation+silicon oil for complicated macular-off rhegmatogenous retinal detachment (RRD) postoperatively using enhanced depth imaging (EDI) spectral domain optical coherence tomography (SD-EDI-OCT).
Materials and Methods: The medical charts of 18 patients (18 eyes) who underwent PPV+laserphotocoagulation+C3F8 (Group-1; n=10 eyes) versus PPV+laserphotocoagulation+silicon oil (Group-2; n=8 eyes) for complicated macula-off RRD were retrospectively analyzed. Postoperative SD-EDI-OCT images concerning SCT were evaluated 1 week, 1 month and 6 months postoperatively in 2 groups. SCT was compared between the groups and with the non-operated fellow eye.
Results: SCT in groups 1 and -2 was thicker 1 week postoperatively compared with SCT after 1- and 6 months. SCT after PPV was not different 1- and 6 months postoperatively when comparing the operated eye with the non-operated fellow eye. There were no significant differences between the groups 1 week, 1- and 6 months postoperatively.
Conclusion: SCT after PPV+laserphotocoagulation+C3F8 and PPV+ laserphotocoagulation+silicon oil in cases with complicated macular-off RRD was thicker 1 week postoperatively. Thicker SCT 1 week postoperatively may most likely by temporary scleral and choroidal inflammation after laserphotocoagulation during PPV. Postoperatively after longer period there was no significant difference in SCT in two groups, that we conclude silicon oil or C3F8 did not influence SCT different.
