BACKGROUND: Complete posterior lens dislocation secondary to posterior capsule rupture following blunt trauma is an extremely rare condition that is easily missed in clinical practice. Here we report a rare case in a 90-year-old patient and summarize its imaging characteristics and surgical management.
CASE PRESENTATION: A 90-year-old female presented with 20 days of decreased visual acuity in the right eye after blunt trauma. Examinations showed an intact anterior capsule with posterior capsule rupture, complete dislocation of the lens cortex and nucleus into the vitreous cavity, zonular dehiscence, and optic disc pallor of unclear etiology. The patient underwent pars plana vitrectomy, lensectomy, and scleral-fixated intraocular lens (IOL) suspension. Postoperative visual acuity improved gradually, intraocular pressure (IOP) remained stable, and the IOL was well-centered.
CONCLUSION: Posterior capsule rupture with complete posterior lens dislocation is a rare ocular trauma. Multimodal imaging aids in definitive diagnosis, and individualized minimally invasive surgery is safe and effective. Special attention should be paid to concomitant occult optic neuropathy in elderly patients.
