title: Intravitreal implant migration into anterior chamber in a post-vitrectomy eye with central retinal vein occlusion and persistent macular edema.
abstract: The authors report the case of a 76-year-old man with a history of central retinal vein occlusion with persistent macular edema in the pseudophakic left eye, which was vitrectomized after complicated retinal detachment surgery. Two weeks after treatment with an intravitreal dexamethasone implant, the implant migrated into the anterior chamber. Visual acuity was hand motion in the right eye and 20/40 in the left eye with corneal edema. One week later, the implant relocated back into the vitreous cavity without surgical intervention, with a marked decrease in corneal edema and improved visual acuity (20/30) in the left eye. Weak zonules and posture change may have caused implant migration in this patient.
