Spontaneous posterior dislocation of nucleus with synchysis scintillans.

We report a case of a 70-year-old male, who presented with posterior dislocation of the nucleus following spontaneous rupture of the posterior capsule and the presence of cholesterol crystals in the vitreous cavity clinically visible as synchysis scintillans. Surgical intervention in the form of pars plana vitrectomy, phacofragmentation and implantation of a Posterior Chamber Intra Ocular Lens (PCIOL) in the ciliary sulcus, over the remnant anterior capsule resulted in an excellent restoration of visual acuity. This is the first report of a case of spontaneous nucleus dislocation secondary to posterior capsule rupture associated with synchysis scintillans, to the best of our knowledge.
