Insights
Early surgical intervention for dense persistent pupillary membranes (PPM) and cataracts significantly improves vision in infants. This case highlights successful treatment for reduced visual acuity.
Area of Science:
- Ophthalmology
- Pediatric Ophthalmology
Background:
- Persistent pupillary membranes (PPM) are common congenital anomalies, present in 95% of neonates.
- Extensive PPM occluding the visual axis, leading to reduced visual acuity, are rare.
Observation:
- A 4-year-old boy presented with decreased visual acuity in his left eye.
- Examination revealed a dense, extensive PPM associated with anterior polar cataract.
Findings:
- Surgical excision of the PPM, lens aspiration, posterior capsulorhexis, anterior vitrectomy, and intraocular lens implantation were performed.
- Post-operatively, visual acuity improved to 0.25 within 8 weeks.
Implications:
- Early surgical treatment is crucial for dense PPM with polar cataracts.
- Membranectomy, lens aspiration, and IOL implantation effectively clear the visual axis and manage amblyopia.
Background:
Persistent pupillary membranes are a common congenital anomaly seen in 95% of neonates. Extensive persistent pupillary membranes, occluding the visual axis and resulting in reduced visual acuity, are relatively uncommon.
Case Report:
A 4-year-old male infant was seen in our hospital with reduced visual acuity of his left eye. Slit-lamp examination revealed a dense, extensive, persistent pupillary membrane associated with anterior polar cataract. We performed an excision of the pupillary membrane, lens aspiration of the lens material, posterior capsulorhexis, anterior vitrectomy and placement of a posterior chamber-intraocular lens in the capsular bag. 8 weeks after operation visual acuity improved to 0.25.
Conclusions:
Dense pupillary membranes associated with polar cataract require early surgical treatment. Membranectomy, lens aspiration and implantation of an intraocular lens clear the visual axis and optimize the treatment of amblyopia.
