Summary
Optical coherence tomography (OCT) is crucial for distinguishing optic nerve head drusen (ONHD) from papilledema. Advanced OCT technologies accurately detect and characterize ONHD, aiding diagnosis and management.
Area of Science:
- Ophthalmology
- Neuro-ophthalmology
Background:
- Differentiating mild papilledema from pseudopapilledema is clinically challenging.
- Accurate diagnosis is essential to prevent unnecessary invasive procedures and treatments.
Purpose of the Study:
- To review the role of optical coherence tomography (OCT) in diagnosing optic nerve head drusen (ONHD).
- To differentiate ONHD from papilledema and other optic disc swelling causes.
Main Methods:
- Review of newer OCT technologies, including enhanced depth imaging (EDI) and swept-source (SS) OCT.
- Evaluation of OCT's ability to detect and characterize ONHD.
Main Results:
- EDI and SS OCT are highly sensitive and reliable tools for diagnosing ONHD.
- Current OCT devices quantify drusen dimensions and assess surrounding optic nerve structures.
- OCT provides insights into the relationship between drusen morphology and optic nerve damage.
Conclusions:
- OCT is indispensable for accurate diagnosis of ONHD.
- Advanced OCT imaging aids in understanding the impact of ONHD on optic nerve structure and function.
