Purpose. To determine the efficacy, safety, and predictive outcome factors for intravitreal dexamethasone implant (DEX) in pseudophakic cystoid macular edema (PCME). Methods. Retrospective, interventional, controlled study. Patients included had to have clinically significant PCME and have been treated with the DEX between 2012 and 2015. Charts and one-year data were selected consecutively, and efficacy and safety were abstracted. Visual acuity (VA) and central foveal thickness (CFT) were analysed. Results. Nineteen patient data sets were analysed. After treatment with DEX, mean VA increased significantly by 0.2 logMAR (p=0.034), while the mean CFT was reduced significantly by 162.79 μm (p<0.001). Five patients receiving a combination of DEX/bevacizumab have not experienced a higher mean VA gain or CFT reduction compared to fourteen patients receiving DEX alone. Decision rules, when to combine DEX with bevacizumab, have not been defined before the study. Only posttreatment VA gains in the nonhypertensive subgroup (n=11) were significantly better (p=0.026). Analysis of data from diabetes patients (n=4) versus nondiabetics yielded no significant differences in efficacy. There have been no adverse events within follow-up time. Conclusion. The use of DEX in PCME showed significant improvements in VA and CFT. The VA seems to show greater improvements in patients without hypertension.
