TitreNon-adjustable strabismus surgery for vertical deviations in thyroid-associated orbitopathy
Abstract Nr.148
ButTo evaluate the results of non-adjustable suture surgery in patients with pure vertical strabismus secondary to thyroid-associated orbitopathy and to identify the risk factors leading to vertical undercorrections or overcorrections.
MéthodesThe records of 25 patients who underwent surgery in the past 10 years for restrictive vertical strabismus were retrospectively reviewed. All 25 patients had preoperative diplopia and restricted elevation in one or both eyes. Treatment consisted in a fixed or non-adjustable suture surgery of the vertical extaocular muscles, mostly the inferior rectus muscle. Five patients had a 3-wall orbital decompression prior to surgery.

RésultatsNine patients were free of diplopia after one operation, 11 patients had diplopia in extreme directions of gaze and 5 patients still had permanent diplopia. Re-operation was necessary in 4 patients, one patient was satisfied with permanent prism correction. After re-operation 2 patients continued to have diplopia which could be corrected with prisms. In total only 2 patients were overcorrected and were both successfully treated with small prisms. In 4 patients the improvement of elevation was disappointing.
ConclusionNon-adjustable strabismus surgery gives good results with minor overcorrection in restrictive vertical deviations secondary to thyroid-associated orbitopathy.
