Table 6.

This is a table. Severity classification of GO. The management of patients depends on the severity which is established according to the impact of the disease on the patient’s quality of life and the risk of vision loss. The disease is classified as mild, moderate, severe, or sight-threatening as follows [1].

Mild	GO has a minor impact on the patient’s everyday life. They usually present one or more of the following signs: 1. Minor lid retraction (<2 mm) 2. Mild soft tissue involvement 3. Exophthalmos < 3 mm (above the normal range for the race and gender) 4. Transient or no diplopia 5. Corneal exposure with a good response to lubricants.
Moderate to severe	patients without sight-threatening GO whose eye disease has sufficient impact on daily life to justify the risks of immunosuppression (if active) or surgical intervention (if inactive). Patients usually present one or more of the following signs: 1. Lid retraction (>2 mm) 2. Moderate or severe soft tissue involvement 3. Exophthalmos ≥3 mm (above the normal range for the race and gender) 4. Inconstant, or constant diplopia.
Sight-threatening GO	Patients with dysthyroid optic neuropathy or corneal breakdown due to severe exposure. Other infrequent cases are ocular globe subluxation, severe forms of frozen eye, choroidal folds, and postural visual darkening. This category warrants immediate intervention.

GO: Graves’ Orbitopathy.
