To evaluate the effectiveness of a single intravitreal injection of dexamethasone implant, over 6 months in patients with recalcitrant CME due to Irvine-Gass syndrome.
Retrospective review of the medical records of nine patients with refractory macular edema (ME) due to Irvine-Gass syndrome, who underwent a single intravitreal injection of dexamethasone implant, Ozurdex, between November 2010 and January 2012, at the Instituto de Microcirurgia Ocular, Barcelona, Spain. All patients underwent a complete ophthalmic evaluation, including best-corrected visual acuity (BCVA) using standardized ETDRS charts, tonometry, fluorescein angiography, and spectral-domain optical coherence tomography with foveal thickness (FT) measurement.
The mean duration of CME before treatment with Ozurdex was 9.1 months (range, 6–13 months). At baseline, the mean FT was 542.22 ± 134.78 μm. Mean (SD) values of FT did decrease to 350.88 ± 98.71 μm (P = 0.001) at month 1 and 319.22 ± 60.96 μm (P = 0.002) at month 3. Data on the 6-month follow-up showed a mild increase 398.33 ± 127.89 μm (P = 0.031). The mean (SD) change from baseline FT was 191.33 μm (a decrease value of 35%) at month 1, and 223.00 μm (decrease value of 41%) and 143.89 μm (decrease value of 26%) at month 3 and month 6, respectively. The baseline BCVA data were 0.62 ± 0.15 logarithm of the minimum angle of resolution (logMAR). The mean BCVA improved to 0.47 ± 0.21 logMAR (P = 0.008) and 0.37 ± 0.24 logMAR (P = 0.001) after month 1 and month 3, respectively. At the last visit (6-month follow-up), the mean BCVA was 0.37 ± 0.26 logMAR (P = 0.002).
In this study, both mean FT and mean BCVA had improved from baseline by 1 month after treatment with a dexamethasone implant, and the improvement remained statistically significant throughout the 6-month study.
