Hyperplastic persistent pupillary membrane--surgical management
Insights
Persistent pupillary membranes in infants require timely surgical intervention. Early treatment prevents amblyopia (lazy eye) and ensures normal visual development.
Area of Science:
- Ophthalmology
- Pediatric Medicine
- Surgical Science
Background:
- Persistent pupillary membranes (PPMs) are congenital anomalies that can obstruct vision.
- Sporadic, isolated PPMs can present as dense membranes, challenging visual axis patency.
Observation:
- Two infants presented with dense, extensive PPMs unresponsive to mydriatic agents.
- The first infant was 3 days old, and the second was 6 weeks old at presentation.
Findings:
- Surgical removal of PPMs was performed on both infants at 5 days and 6 months of age, respectively.
- Both surgeries were uncomplicated, with subsequent normal visual development observed.
Implications:
- Early surgical intervention within the first weeks or months of life is crucial for preventing amblyopia.
- Following surgery, optical correction and occlusion therapy may be necessary based on individual visual development needs.
Abstract:
Two infants, aged three days and six weeks, respectively, presented with dense extensive persistent pupillary membranes as sporadic isolated findings. A clear central pupillary aperture was unable to be achieved with mydriatic agents. The patients were treated by surgical removal of the membranes at age five days and six months respectively. Surgery was without complication and visual development has been normal. We suggest that early intervention in the first weeks or months of life is necessary to prevent the development of amblyopia. If mydriasis is unsuccessful, surgery is recommended followed by optical correction and occlusion therapy as necessary.
