Dislocated Intraocular Lens with Vasoproliferative Tumor

This wide angle fundus image was taken of the right eye of a 79-year-old male patient with sudden decrease in vision of the right eye from dislocation of his posterior chamber intraocular lens. He previously had vitrectomy surgery for repair of a retinal detachment, which probably broke some zonules and predisposed him to this complication. The dislocated IOL displacement is indicated by the red arrow. Under the IOL is a retinal vasoproliferative tumor (yellow arrow). Treatments for a dislocated IOL include lens repositioning, lens removal and periodic observation without intervention. This patient chose observation. There has been no change in the appearance over several years of follow-up.
