In the context of dysthyroid orbitopathy, exophthalmos is common and can cause real suffering in patients' social lives. The reversibility of this exophthalmos depends on the severity of the orbitopathy and the effectiveness of the treatment. In the early stages of the disease, exophthalmos may be mild and reversible, with no need for specific treatment. In more advanced cases, where the exophthalmos is severe and persistent, different options may be proposed alongside stabilising hormonal treatment and anti-inflammatory treatment with corticosteroids. In this case, treatment may involve orbital decompression surgery, which consists of removing part of the orbital bone in order to reduce the pressure around the eyes and free up more space in the bone cavity to move the eye backwards and thus treat the exophthalmos.
