Background

Optic disc drusen (optic disc drusen), which can mimic papilledema and pose a diagnostic challenge to ophthalmologists, can be effectively detected using computed tomography (computed tomography).

Methods

This was a retrospective chart review of consecutive patients with optic disc drusen with previous brain computed tomography scan performed for various unrelated reasons.

n = 43 eyes

32%

Results

32%

radiology reports missed disc drusen in most computed tomography scans checked

n = 43 eyes

More results

Optic disc drusen were bilateral in 20 patients (87.0%) and unilateral in 3 (13.0%).

It was mentioned in all 5 scans performed for unrelated neuro-ophthalmic indications.

“

Conclusion · 1 of 3

In conclusion, optic disc drusen were underreported on computed tomography scans, with only 32% of reports explicitly mentioning their presence.

Conclusion · 2 of 3

This has implications for radiologists, who should be aware of the importance of optic disc drusen to ophthalmologists, who may look back at previous computed tomography scans.

Conclusion · 3 of 3

Ophthalmologists should be aware that the absence of an optic disc drusen mention in a computed tomography report does not indicate the absence of optic disc drusen on the imaging.

Post
