Surgical management of persistent hyperplastic primary vitreous

Area of Science:

• Ophthalmology
• Surgical Techniques
• Pediatric Eye Care

Background:

• Congenital cataracts present complex management challenges.
• Persistent hyperplastic primary vitreous (PHPV) is a severe form of congenital cataract.
• Standard cataract surgeries may be insufficient for complicated cases.

Purpose of the Study:

• To evaluate the efficacy of pars plana vitrectomy for complicated congenital cataracts.
• To assess the application of closed-eye vitrectomy techniques in PHPV management.
• To discuss the surgical approach for pediatric congenital cataracts.

Main Methods:

• Application of closed-eye vitrectomy.
• Surgical approach through the limbus.
• Management of seven eyes diagnosed with PHPV.

Main Results:

• Successful clearing of the pupillary space in all seven cases.
• Demonstrated feasibility of the closed-eye vitrectomy technique.
• Achieved a clear visual axis post-operatively.

Conclusions:

• Pars plana vitrectomy is a viable surgical option for complicated congenital cataracts.
• Closed-eye vitrectomy via a limbal approach offers a solution for PHPV.
• The technique facilitates improved visual outcomes in affected children.
