INTRODUCTION

To report the long-term surgical outcomes and the impact on daily life activities of strabismus surgery in patients with Thyroid Associated Orbitopathy (TAO).

METHODS

Patients who underwent strabismus surgery for TAO were retrospectively reviewed. The primary outcome was to evaluate the influence of orbital decompression on the outcomes of TAO related strabismus surgery. Surgical success was defined by the resolution of diplopia and a post-operative deviation <10 prism diopters (PD). The secondary outcomes were the clinical features, surgical approaches, and impact on daily life activities.

RESULTS

A total of 45 patients were included in the study: 21 patients (46.7%) in the decompression surgery group (DS), and 24 (53.3%) in the non-decompression surgery group (NDS).

The mean follow-up time was 2,8 years (range 8 – 200 months).

Successful surgical outcome was achieved in 57,1% in the DS, and 75% in the NDS (p=0,226).

DS patients required almost twice the number of surgical interventions for strabismus compared to the NDS (1,95 vs 1,16; p=0,006), and a higher number of extraocular muscles recessed (2,67 vs 1,08;

Moreover, 21,8% of NDS patients used prism lenses in daily life activities, compared to 42.9% of patients that used prism lenses to reduce the impairment in their daily life activities (p=0.016).

CONCLUSIONS

DS patients required almost twice the number of strabismus surgical procedures, a higher number of extraocular muscles recessed, and an increased need for prism lenses to correct the residual deviation compared to the NDS, but with similar long-term surgical outcomes.
