Electroretinography in neonates treated with phototherapy

Area of Science:

• Ophthalmology
• Neonatal Medicine
• Neuroscience

Background:

• Neonatal jaundice is common and often treated with phototherapy.
• Concerns exist regarding potential adverse effects of phototherapy on infant vision.
• Electroretinography (ERG) is a key diagnostic tool for assessing retinal function.

Purpose of the Study:

• To evaluate the impact of phototherapy on retinal function in neonates.
• To compare electroretinographic (ERG) parameters between infants treated with phototherapy and a control group.

Main Methods:

• Electroretinographic (ERG) studies were conducted on 28 neonates post-phototherapy and 22 healthy controls.
• Funduscopy was performed to ensure normal ocular health in both groups.
• ERG assessed scotopic and photopic retinal function under dark- and light-adapted conditions.

Main Results:

• No significant differences were observed in the amplitudes of a and b waves between the phototherapy and control groups.
• Routine funduscopy revealed normal results in all infants studied.
• Phototherapy did not demonstrate deleterious effects on either photopic or scotopic retinal function.

Conclusions:

• Adequate eye shielding during phototherapy appears to prevent adverse effects on neonatal retinal function.
• ERG findings suggest that phototherapy is safe for retinal function in neonates when eyes are properly protected.
