Insights
Early surgery for bilateral congenital cataracts in infants is crucial. Prompt intervention, especially between 2-6 months, prevents deprivation amblyopia and achieves good visual outcomes.
Area of Science:
- Ophthalmology
- Pediatric Medicine
- Microsurgery
Context:
- Congenital cataracts affect infants, potentially leading to severe vision impairment.
- Bilateral congenital cataracts require timely surgical intervention.
- Early diagnosis and management are critical for visual development.
Purpose:
- To evaluate the efficacy and safety of microsurgical techniques for bilateral congenital cataracts in infants.
- To determine optimal surgical timing for preventing deprivation amblyopia.
- To analyze preoperative findings and postoperative outcomes.
Summary:
- The study involved 89 infants (2-10 months) with bilateral congenital cataracts undergoing microsurgery.
- Preoperative assessments included biomicroscopy, retinoscopy, and electrophysiologic tests.
- Various closed-type microsurgical techniques were employed, achieving good optical and functional results with minimal complications.
- The postoperative period was largely uneventful (84.5%), with secondary cataracts in 6% of cases.
Impact:
- Early surgical intervention (2-6 months) is indicated for congenital cataracts causing deprivation amblyopia.
- Microsurgical techniques demonstrate safety and effectiveness in treating pediatric cataracts.
- This research supports timely surgical management to preserve vision in affected infants.
Abstract:
The examinations have involved 89 children with bilateral congenital cataracts aged 2-6 months (n = 68) and 7-10 months (n = 21). The preoperative examinations have been carried out under anesthesia and included biomicroscopy, retinoscopy, ultrasonic and electrophysiologic examinations. A number of specific clinical and functional features have been revealed in these babies. Surgery has been performed in 148 eyes. Various types of microsurgical techniques of the closed type have been employed: aspiration-irrigation method; operations with ultrasonic equipment y3X-phi-p04-0 and Sparta, lensectomy using the Okutom system. An anterior approach to the lens via an incision in the limbus has been used. Good optical and functional results have been achieved. No grave intraoperative complications have been recorded. The postoperative period has been areactive in 84.5% of cases. In 6% of cases secondary cataracts have developed, mostly of Elschnig's pearls. Early surgery (at the age of 2-6 mos) is indicated in all forms of congenital cataracts inducing deprivation amblyopia.
