Using autofluorescence to detect optic nerve head drusen in children.

Area of Science:

• Ophthalmology
• Medical Imaging
• Pediatric Eye Care

Background:

• Optic nerve head drusen (ONHD) can mimic papilledema in children, necessitating accurate diagnostic methods.
• Pseudopapilledema evaluation requires differentiating true optic disc swelling from other conditions.

Purpose of the Study:

• To evaluate the diagnostic efficacy of autofluorescence imaging for identifying optic nerve head drusen (ONHD) in pediatric patients.
• To determine the reliability of autofluorescence in detecting both visible and hidden ONHD.

Main Methods:

• A cross-sectional study involving children under 18 with suspected pseudopapilledema.
• Comparison of autofluorescence imaging with B-scan ultrasonography as the gold standard.
• Masked analysis of autofluorescence images by three independent observers.

Main Results:

• Autofluorescence successfully identified ONHD in 94% of affected eyes (30/32).
• Detection rates were 100% for visible drusen and 92% for hidden drusen.
• High interobserver agreement (κ values ranging from 0.89 to 0.96) was observed.

Conclusions:

• Autofluorescence is a safe, rapid, and dependable tool for diagnosing ONHD in children.
• The technique offers high sensitivity for both apparent and non-apparent optic nerve head drusen.
• Autofluorescence imaging can aid in the accurate diagnosis of pediatric optic neuropathies.
