Insights
Pediatric cataract surgery for persistent hyperplastic primary vitreous (PHPV) is effective but carries risks. Both anterior and posterior approaches can remove membranes, though complications like corneal decompensation or retinal detachment may occur.
Area of Science:
- Ophthalmology
- Pediatric Surgery
Context:
- Persistent hyperplastic primary vitreous (PHPV) is a congenital condition causing pediatric cataracts.
- Accurate anatomical assessment using high-frequency ultrasonography is crucial before surgical intervention.
Purpose:
- To evaluate surgical techniques for safe and effective removal of lens and retrolenticular fibrotic membranes in pediatric PHPV.
- To compare complication rates between anterior and posterior surgical approaches.
Summary:
- Thirty-one children with PHPV and cataract underwent surgery via either limbal cataract extraction with vitrectomy (anterior approach, 17 eyes) or pars plana vitrectomy (posterior approach, 14 eyes).
- The anterior approach was associated with corneal decompensation, while the posterior approach carried a risk of retinal detachment.
- Both techniques proved effective in removing membranes but presented significant intraoperative and postoperative complication risks.
Impact:
- Surgical intervention is necessary to prevent further pathological changes and optimize visual outcomes in pediatric PHPV.
- Understanding the risks associated with each surgical approach aids in patient counseling and surgical planning.
Purpose:
To evaluate the surgical techniques that allows safe, effective removal of lens and retrolenticular fibrotic membranes in eyes with PHPV in children.
Material And Methods:
A total of 31 children (18 boys and 13 girls) with PHPV and cataract in one eye were divided into 2 groups, according to treatment modality. High frequency ultrasonography were used to identify anatomic correlates in the eyes--before operation. Limbal cataract extraction combined with vitrectomy and removalof embryonic remnants was carried out in 17 eyes, and a posterior pars plana approach in 14 eyes.
Results:
In group with anterior approach, the most serious complication was corneal decompensation, in the next group--retinal detachement.
Conclusions:
The anterior and the posterior surgical technique to remove cataract and tenacious retrolenticular membranes was effective but associated with high risk of intraoperative and postoperative complications. Although the surgical intervention is necessary to prevent progressive pathologic changes and to obtain the best possible visualresults in some cases.
