Factors affecting visual outcome after surgery for bilateral congenital cataracts

Area of Science:

• Ophthalmology
• Pediatric Medicine
• Genetics

Background:

• Dense bilateral congenital cataracts are a significant cause of visual impairment in children.
• Early intervention is crucial for visual development.
• Understanding factors influencing visual outcomes is essential for patient management.

Purpose of the Study:

• To analyze factors affecting visual outcomes in patients with dense bilateral congenital cataracts.
• To identify prognostic indicators for visual acuity and binocular vision.

Main Methods:

• Retrospective analysis of 33 patients with dense bilateral congenital cataracts.
• Evaluation of factors including age at surgery, nystagmus, microphthalmos, strabismus, ocular and systemic anomalies, and postoperative complications.
• Assessment of postoperative visual acuity and binocular vision over an average follow-up of 6.3 years.

Main Results:

• 14 out of 23 tested patients achieved visual acuities of 20/80 or better.
• Eight patients demonstrated binocular vision.
• Preoperative nystagmus, age at surgery, microphthalmos, and postoperative strabismus were not significant predictors of visual outcome.
• Postoperative nystagmus was common but not indicative of poor visual prognosis.
• Ocular anomalies, systemic anomalies, and postoperative complications were associated with reduced good visual acuities.

Conclusions:

• While many factors do not predict visual outcome in congenital cataracts, the presence of ocular or systemic anomalies and postoperative complications are associated with poorer visual results.
• Postoperative nystagmus should not be considered a definitive negative prognostic indicator.
