Quantitative computed tomographic predictors of compressive optic neuropathy in patients with thyroid orbitopathy: a volumetric analysis.

Purpose: To evaluate the relationship between orbital bony geometry and the volume of the intraorbital structures in predicting compressive dysthyroid optic neuropathy (DON).

Design: Retrospective, consecutive case series.

Participants: Images of 198 orbits from 99 patients suffering from thyroid-related orbitopathy were reviewed.

Clinical and soft-tissue computed tomographic predictors of dysthyroid optic neuropathy: refinement of the constellation of findings at presentation.

Objective: To evaluate the ability to predict the presence of dysthyroid optic neuropathy (DON) using computed tomography assessment of soft-tissue and clinical features.

Study Design: A retrospective consecutive case series of patients with thyroid-related orbitopathy.

Results: One hundred eighty-nine orbits from 99 patients were evaluated.
