Insights
Blunt eye trauma can cause isolated posterior capsule rupture (PCR) in young patients, leading to traumatic cataracts. Successful treatment involves intraocular lens (IOL) implantation, restoring vision.
Area of Science:
- Ophthalmology
- Trauma Surgery
Background:
- Posterior capsule rupture (PCR) is a rare complication of traumatic cataracts.
- This study focuses on isolated PCR resulting from blunt ocular trauma.
Purpose of the Study:
- To report findings in three cases of traumatic cataracts with isolated PCR.
- To highlight the mechanism and successful management of these injuries.
Main Methods:
- Case series involving three young males with traumatic cataracts and isolated PCR.
- Diagnostic tools included anterior segment optical coherence tomography and ultrasonography.
Main Results:
- Isolated PCR with lens cortex prolapse was observed in Case 3.
- Intraocular lens (IOL) implantation was performed in the capsular bag or ciliary sulcus.
- Vision improved in all affected eyes following treatment.
Conclusions:
- Blunt eye trauma can cause isolated PCR with lens cortex protrusion in pediatric patients.
- Successful surgical outcomes are achievable with IOL implantation, either within or outside the capsular bag.
Introduction:
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.
Presentation Of Cases:
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.
Discussion:
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.
Conclusions:
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.
