# Isolated posterior capsule rupture secondary to blunt ocular trauma: Case presentation and literature review

## TL;DR

This paper reports three cases of rare eye injuries in young patients where blunt trauma caused a posterior capsule rupture and cataract, successfully treated with intraocular lens implantation.

## Contribution

The novelty lies in documenting isolated posterior capsule rupture in very young patients and emphasizing successful treatment strategies.

## Key findings

- Blunt ocular trauma can cause isolated posterior capsule rupture with lens cortex protrusion in young patients.
- Intraocular lens implantation improved vision in all three reported cases.
- Literature suggests isolated PCRs mainly occur in teenagers and men, with some requiring immediate surgery.

## Abstract

An isolated posterior capsule rupture (PCR) is a rare complication associated with traumatic cataracts. We report our findings in three cases of traumatic cataracts with isolated PCR caused by blunt ocular trauma.

Case 1: A 1.5-year-old boy was examined after his parents noticed that the center of the pupil of the left eye was white. The mother reported that the boy had fallen and bruised his left forehead 4 months earlier. Case 2: An 18-year-old boy had a traumatic cataract that developed one month after a blow to his eye. Case 3: A 13-year-old boy was treated for hyphema and high intraocular pressure after blunt trauma to his eye. Ten days later, a total cataract developed. Anterior segment optical coherence tomography revealed an isolated PCR with a protruding lens cortex, and ultrasonography showed vitreous opacities.

An isolated PCR was observed intraoperatively in the center of the posterior lens capsule. The lens cortex was prolapsed into the PCR or into the vitreous cavity in Case 3. An intraocular lens (IOL) was implanted in the lens capsule or to the ciliary sulcus after vitrectomy in Case 3. Vision improved in all eyes.

Our findings indicated that the external force by a trauma to the eye can lead to an isolated PCR with a protruded lens cortex in young patients. These PCRs can be successfully treated with the IOL implanted in or out of the capsular bag.

•We reported 3 cases of an isolated posterior capsule rupture and cataracts.•Our cases included a very young patient of 1.5 years of age.•All three cases were treated with the implantation of an intraocular lens.•The isolated PCRs developed mainly in teenagers and men in the literature.•Some cases required surgery immediately in the literature.

We reported 3 cases of an isolated posterior capsule rupture and cataracts.

Our cases included a very young patient of 1.5 years of age.

All three cases were treated with the implantation of an intraocular lens.

The isolated PCRs developed mainly in teenagers and men in the literature.

Some cases required surgery immediately in the literature.
