[A suggestion on the microsurgical treatment of the persistent hyperplastic primary vitreous body (PHPV) (author's
Insights
Surgical removal of persistent hyperplastic primary vitreous (PHPV) is a viable treatment for affected children. While cosmetic outcomes are good, visual acuity remains a significant challenge post-operation.
Area of Science:
- Ophthalmology
- Pediatric Surgery
Background:
- Persistent hyperplastic primary vitreous (PHPV) is a congenital condition often misdiagnosed as retinoblastoma in children.
- Early diagnosis and intervention are crucial for managing PHPV and its potential complications.
Observation:
- Three pediatric cases of PHPV are presented, initially suspected as retinoblastoma.
- Surgical intervention involved microscopic anterior chamber access via a 180-degree corneal incision for PHPV extirpation.
Findings:
- Careful management of the A. hyaloidea vessel during surgery is essential to prevent vitreous hemorrhage.
- While surgical extirpation yielded positive cosmetic results, achieved visual acuity was suboptimal.
Implications:
- The surgical approach for PHPV is technically feasible and offers good cosmetic outcomes.
- Visual rehabilitation challenges following PHPV surgery mirror those seen in unilateral pediatric cataracts.
- Further research is needed to improve visual outcomes in pediatric PHPV patients.
Abstract:
Three children suffering from PHPV are described, who originally had been sent to the hospital because of suspected retinoblastoma. Exstirpation of the PHPV after opening the anterior chamber with a corneal cut of 180 degrees under the microscope seems a recommendable treatment. The A. hyaloidea has to be observed carefully during the preparation. In order to avoid massive hemorrhage into the vitreous, it is necessary to ligate this vessel before cutting. The cosmetical results were good but the visual acuity was unsatisfactory. The problems arising after a successful operation of the PHPV are similar to those in children with unilateral cataract.
