Microsurgery of persistent hyperplastic primary vitreous
Insights
Microsurgical techniques effectively treated persistent hyperplastic primary vitreous (PHPV) in 6 pediatric patients. The surgery improved ocular cosmesis and preserved useful vision, demonstrating a positive outcome for this congenital condition.
Area of Science:
- Ophthalmology
- Pediatric Surgery
Background:
- Persistent hyperplastic primary vitreous (PHPV) is a congenital developmental anomaly of the eye.
- Early diagnosis and surgical intervention are crucial for managing PHPV and preventing amblyopia.
Observation:
- This study involved 6 pediatric patients (5 boys, 1 girl) diagnosed with PHPV.
- The condition affected one or both eyes, with varying laterality.
Findings:
- Microsurgical techniques, including iridectomy, lens suction, and vitreous removal (using Klöti Vitreous Stripper or anterior chamber scissors), were employed.
- No major intraoperative complications occurred. Fundus visualization was achieved in most cases.
- Postoperative visual acuity ranged from light perception to 0.2, with normal intraocular pressure. Useful reserve vision and improved ocular appearance were noted.
Implications:
- Microsurgical management of PHPV can lead to favorable visual outcomes and enhanced ocular cosmesis in pediatric patients.
- These findings support the efficacy of surgical intervention in improving the quality of life for children with PHPV.
- Further research could explore long-term visual function and compare different microsurgical approaches for PHPV.
Abstract:
6 patients with persistent hyperplastic primary vitreous (PHPV) were operated on using microsurgical techniques. There were 5 boys and 1 girl, all with normal birth weight and good general health. PHPV was present in the left eye in 4 patients, in the right eye in 1, and 1 patient had bilateral PHPV. The operative management consisted of a primary large-sector iridectomy (in 4 cases) and suction of the lens, combined with removal of the hyperplastic vitreous using a Klöti Vitreous Stripper in 5 patients, and small anterior chamber scissors in 1 patient. No major operative complications were experienced. The fundus was fully visible in 5 cases while in 1 eye remaining and new proliferations prevented visualization of the fundus. Postoperative visual acuity varied from light perception to 0.2 and the intraocular pressure was within normal limits. It was felt that a useful reserve eye was obtained, with marked improvement of the ocular cosmesis.
