Cataract Formation Following Pars Plana Vitrectomy in the Pediatric Population
Insights
Pediatric pars plana vitrectomy (PPV) significantly increases cataract risk, with 61% of eyes developing cataracts post-surgery. Tamponade agents like octafluoropropane or silicone oil correlate with needing cataract surgery.
Area of Science:
- Ophthalmology
- Pediatric ophthalmology
- Vitreoretinal surgery
Background:
- Cataract formation is a known complication after vitrectomy.
- Understanding the incidence and risk factors in pediatric patients is crucial for managing visual outcomes.
Purpose of the Study:
- To determine the rate of cataract formation after pars plana vitrectomy (PPV) in pediatric patients.
- To identify perioperative factors influencing cataract development and the need for subsequent cataract surgery.
- To examine visual outcomes in pediatric eyes undergoing PPV.
Main Methods:
- Retrospective analysis of pediatric eyes undergoing phakic PPV without prior cataract over 10 years.
- Evaluation of factors including age, tamponade use, ocular trauma, and indication for surgery.
- Assessment of cataract status and time to cataract surgery, along with final visual acuity.
Main Results:
- Cataract formation occurred in 61% of analyzed eyes (27/44).
- 15 eyes (34% of total) required cataract surgery.
- Use of octafluoropropane or silicone oil was associated with increased need for cataract surgery (P=.04, P=.03).
- Eyes needing cataract surgery had worse visual acuity outcomes initially (P=.02).
Conclusions:
- Pediatric pars plana vitrectomy poses a significant risk for cataract development.
- Ophthalmologists should counsel patients on the likelihood of post-vitrectomy cataracts.
- Vigilance and timely intervention are necessary for managing pediatric post-vitrectomy cataracts.
Purpose:
To analyze post-vitrectomy cataract formation in the pediatric population to elucidate the number of phakic children requiring cataract surgery following vitreous surgery and the perioperative factors affecting cataract development in these patients.
Methods:
Eyes of pediatric patients that underwent phakic pars plana vitrectomy (PPV) with no prior cataract in a 10-year period were included. Analyses evaluated relationships between patient age and time to cataract surgery, as well as contributing factors for cataract formation. Final visual outcomes were also examined. Outcomes were collected for patient age at first vitrectomy, indication for vitrectomy, use of tamponade agents, history of ocular trauma, cataract status, and time to cataract surgery from first vitrectomy.
Results:
Of 44 eyes analyzed, 27 (61%) were noted to have some degree of cataract formation. Of these, 15 (56%; 34% of total eyes) underwent cataract surgery. Use of octafluoropropane (P = .04) or silicone oil (P = .03) positively correlated with the need for cataract surgery in the total study group. Patients requiring cataract surgery had worse endpoint visual acuities than those who did not undergo surgery (P = .02), although this difference becomes less significant in follow-up over 2 years (P = .30). Patients who had cataracts but did not need cataract surgery showed an improvement in visual acuity (P = .04), but this was not demonstrated in patients who did need cataract surgery (P = .90).
Conclusions:
Pediatric eye care providers should be aware of the significant risk of cataract formation following a phakic PPV. [.
