摘要
Objective: To investigate retinal morphologic changes during silicone oil tamponade and after its removal using spectral domain OCT (SD-OCT) imaging.Materials and Methods: Retrospective review of 12 patients who underwent silicone oil tamponade for repair of retinal detachments. Macular OCT scans and volumetric thickness maps were examined qualitatively and quantitatively.Results: Volumetric OCT revealed two distinct patterns during silicone oil: macular thickening (Group A) and macular thinning (Group B). In Group A, mean foveal thickness (507 169 mu m vs. 407 +/- 163 mu m, p = 0.003) and mean macular volume (11.6 +/- 2.4 mm(3) vs. 9.9 +/- 1.5 mm(3)) were significantly increased during tamponade compared to post-oil removal. Group B had significantly decreased mean foveal thickness (210 +/- 38 mu m vs. 276 +/- 58 mu m, p = 0.009) and macular volume (7.3 +/- 1.8 mm(3) vs. 8.4 +/- 1.8 mm(3)) during tamponade. Importantly, resolution of macular changes occurred without further intervention and was associated with improved visual acuity in both groups.Conclusion: Our series suggests that when faced with unexplained macular edema or macular thinning during tamponade, silicone oil removal alone can achieve resolution of these structural changes.
