Graves' orbitopathy reaches its most critical classification — very severe, or sight-threatening — when dysthyroid optic neuropathy and/or corneal breakdown are present. When immediate high-dose intravenous methylprednisolone does not produce the required response, a defined escalation pathway applies.
Patients with dysthyroid optic neuropathy and/or corneal breakdown represent the sight-threatening (very severe) category of Graves' orbitopathy. Visual function is directly at risk and prompt clinical decision-making is essential.
The established first-line intervention for sight-threatening Graves' orbitopathy is immediate high-dose intravenous methylprednisolone. This protocol applies when that treatment fails: specifically, when evaluation after one week of therapy shows an absent or poor response — without improvement in visual acuity and visual fields — or when there is active deterioration in those parameters.
