A CT radiomics nomogram predicts visual acuity improvement in patients with indirect traumatic optic neuropathy following optic canal decompression.

The final nomogram incorporated nine radiomics features and three clinical predictors.

It demonstrated robust discriminative ability, with area under the curve values of 0.840 in the training set and 0.832 in the test set.

This tool effectively categorized patients into distinct risk groups for poor visual acuity recovery.
