Insights
Surgical intervention for secondary glaucoma in infants with anterior-anterior persistent fetal vasculature (AAPFV) improved intraocular pressure and cosmetic outcomes. Most infants experienced better vision and corneal transparency post-surgery.
Area of Science:
- Ophthalmology
- Pediatric Ophthalmology
- Glaucoma Research
Background:
- Persistent fetal vasculature (PFV) can lead to secondary glaucoma in infants.
- Anterior-anterior persistent fetal vasculature (AAPFV) is a specific subtype requiring targeted investigation.
- Understanding clinical features and surgical outcomes is crucial for managing pediatric glaucoma.
Purpose of the Study:
- To investigate the clinical features of infants diagnosed with glaucoma secondary to AAPFV.
- To evaluate the surgical outcomes of infants undergoing specific procedures for AAPFV-related glaucoma.
- To assess the efficacy of surgical interventions in improving intraocular pressure and visual function.
Main Methods:
- Retrospective review of medical records for infants with AAPFV and secondary glaucoma.
- Surgical procedures included synechialysis, pupilloplasty, lensectomy, and limbal vitrectomy.
- Minimum 6-month postoperative follow-up was required for inclusion.
Main Results:
- Eleven infants were included, with a median age of 4 months at surgery.
- All patients achieved normal anterior chamber, improved pupillary configuration, and controlled intraocular pressure (IOP), except one case of phthisis bulbi.
- 81.8% of eyes showed improved corneal transparency, and 6/9 patients improved visual acuity from no light perception to light perception.
Conclusions:
- AAPFV is a distinct PFV type associated with secondary glaucoma in infants.
- Surgical treatment for AAPFV-related glaucoma can lead to improved vision, IOP control, and cosmetic results.
- Early surgical intervention may be beneficial for managing this condition.
Purpose:
To investigate the clinical features and surgical outcomes in infants with glaucoma secondary to a special anterior-anterior type of persistent fetal vasculature (AAPFV).
Methods:
This study retrospectively reviewed the medical records of infants who underwent of the synechialysis, pupilloplasty, with or without lensectomy and limbal vitrectomy due to AAPFV and with at least 6 months of postoperative follow-up.
Results:
Eleven patients were included. The median age at surgery was 4.0 months (interquartile range: 7 months). The mean follow-up was 21.0 ± 11.3 months. All patients achieved a normal anterior chamber, improved pupillary configuration, and normal intraocular pressure (IOP), except one that developed phthisis bulbi at the last visit. A total of 81.8% (9/11) eyes exhibited improved corneal transparency. Histopathologic findings of four pupillary membranous specimens under light microscopy showed similar components compared with PFV. Two eyes developed postoperative complications, including retinal detachment and hyphema, requiring additional surgeries. Postoperative visual acuity changed from no light perception to light perception in 6/9 patients.
Conclusions:
AAPFV is a special type of PFV with a potential for secondary glaucoma. Surgery treatment may offer better vision with improved cosmetic outcomes and a better controlled IOP.
Trial Registration:
The study was approved by the local institutional review board (IRB) (Approval No. XHEC-D-2021-043, Ethical Committee of Xin Hua Hospital Affiliated to Shanghai Jiao Tong University, Shanghai, China).
