Transient Macular Thinning during the Use of Heavy Silicone Oil, Densiron 68.

Background: To evaluate the effect of short-term tamponade on macular thickness.

Methods: Retrospective case series. Data were collected from charts of patients who received short-term (less than 90 days) . The OCT parameters were compared between and after removal and to the fellow eye.

Results: Twenty eyes were included in the analysis. Although there was a trend toward thinner CRT with Densiron in situ the operated eye when compared to the fellow eye (248 and 264 microns, respectively, = .066), this difference disappeared after DR. At the final OCT there was a statistically significant recovery in the CRT (from 248 to 277 microns, = .001) and no statistical difference between operated and the fellow eye ( = .265) with no evidence of ERM or CME.

Conclusions: We found transient macular thinning that resolved after Densiron removal with no evidence of long-term macular thinning in eyes treated with for retinal detachment.
