Treatment of persistent hyperplastic primary vitreous.

    Summary

    Early surgery for persistent hyperplastic primary vitreous (PHPV) is crucial. While surgical intervention can be anatomically successful, visual outcomes depend heavily on posterior segment involvement, with anterior PHPV offering better visual prognosis.

    Area of Science:

    • Ophthalmology
    • Pediatric Ophthalmology
    • Vitreoretinal Surgery

    Background:

    • Persistent hyperplastic primary vitreous (PHPV) is a congenital developmental anomaly of the eye.
    • It can lead to significant visual impairment if not managed appropriately.

    Purpose of the Study:

    • To evaluate the outcomes of surgical and conservative management for persistent hyperplastic primary vitreous.
    • To identify factors influencing visual results in PHPV patients.

    Main Methods:

    • Retrospective review of 32 patients with PHPV over a 10-year period.
    • Surgical interventions included lensectomy with anterior vitrectomy and, in some cases, full vitrectomy with stalk dissection.
    • Conservative management was employed in two cases.

    Main Results:

    • Five eyes achieved useful vision.
    • Good visual results were exclusively observed in eyes with anterior PHPV involvement only.
    • Posterior segment surgery was anatomically successful but yielded poor visual results due to retinal abnormalities.

    Conclusions:

    • Early intervention for PHPV is recommended to prevent orbital underdevelopment and treat amblyopia.
    • Surgical success in PHPV is contingent on the absence of posterior segment involvement.
    • Conservative management may be considered for select cases, but surgical outcomes are generally poor if the posterior segment is affected.
