[Focus on the controversial problems of orbital decompression in the treatment of dysthyroid optic neuropathy]

Dysthyroid optic neuropathy (DON) is the most common cause of visual loss in thyroid associated ophthalmopathy, for which steroid pulse therapy and orbital decompression are the common treatments currently. While steroid pulse therapy was recommended as the first-choice for DON, orbital decompression remained as an indispensable therapy although controversies on such treatment still exist. The mechanism, approaches and outcomes of orbital decompression, as well as its advantages and disadvantages over steroid pulse therapy were retrospectively reviewed, and it was suggested that the combination therapy of steroid pulse therapy and surgical decompression might be the better choice for the treatment of DON.
