Table 1 Factors influencing the anterior chamber migration of an intravitreal dexamethasone implant. This table illustrates the significant influences of vitrectomized pseudophakic eyes in contrast to nonvitrectomized pseudophakic eyes and vitrectomized eyes with reduced zonular/capsular bag complex integrity in contrast to vitrectomized pseudophakic eyes with intact zonular/capsular bags on the risk of anterior chamber implant migration. Additionally this table illustrates the potential influence of treatment diagnosis for Ozurdex® dislocation
