Have we stopped looking for a red reflex in newborn screening?

Area of Science:

• Ophthalmology
• Pediatric Medicine
• Public Health

Background:

• Congenital cataracts require early surgical intervention for best visual outcomes.
• Timely diagnosis and treatment are critical for preventing long-term visual impairment in infants.

Purpose of the Study:

• To review the timing and source of congenital cataract diagnoses in a specific region.
• To evaluate the visual outcomes at 2 years or more in relation to diagnostic timing.

Main Methods:

• Retrospective study of children under 15 diagnosed with congenital cataracts over 10 years (1991-2002).
• Data collected from a Regional Ophthalmology Centre serving 546,000 population.
• Inclusion criteria: congenital or infantile cataracts, presenting in infancy or with early clinical features.

Main Results:

• 27 cases identified; 17 (63%) diagnosed after parental concerns, only 2 before 3 months.
• General practitioners diagnosed 24%, pediatricians 12%, ophthalmologists 9%. No diagnoses via newborn screening.
• Infants diagnosed before 3 months had better visual outcomes (6/8 good) compared to those diagnosed later (3/19 good).

Conclusions:

• Congenital cataracts must be diagnosed and treated within the first 3 months of life.
• Newborn screening and 6-8 week checks by general practitioners are vital for early detection.
• Parental concerns about vision, like squint, warrant red light reflex examination and prompt ophthalmological referral.
