ABSTRACT.Purpose: To evaluate the outcome of endoscopic decompression in a series of patients with thyroid eye disease. Methods: All 46 patients operated at our institution in the period 2001 to 2011 were invited for re-examination. Thirty-seven patients were included in the study and underwent a general otorhinolaryngological and ophthalmological examination. Nasal endoscopy, autoperimetry and a CT scan of the orbits and paranasal sinuses were performed. Preoperative and early postoperative data were obtained from hospital records. Re-examination was performed from 12 months to 9 years postoperatively. Paired t-test was used to evaluate the change in pre-and postoperative data. Image-guided surgery was used in two patients. Results: Visual acuity improved from a median value (range) of 0.8 (0.05-1.25) to 1.0 (0.4-1.25) (p = 0.006). Intra-ocular pressure (IOP) was reduced from a median value (range) of 18 mmHg (10-27 mmHg) to 14 mmHg (8-24 mmHg) (p < 0.001). Median (range) Hertel values were 22.5 mm (14-29 mm) preoperatively and 19 mm (11-26 mm) postoperatively (p < 0.001). Mean reduction in proptosis was 4.0 mm. At follow-up, visual fields were normal in 16/37 patients (43%) and with small defects in 12/37 patients (32%). Seventeen patients (46%) had diplopia preoperatively in one or more directions of gaze while 9 (24%) suffered from constant diplopia. After endoscopic decompression, new onset diplopia was seen in seven (19%) individuals, while worsening of diplopia occurred in eight (22%). Impaired motility in abduction and/or elevation was seen in 20 (54%) individuals before decompression and in 23 (62%) after. Strabismus surgery was performed in 22 patients. On final examination 85% of the study population were totally free of diplopia or experienced diplopia only in the peripheral field of gaze. Three patients developed sinusitis. Of these, endoscopic sinus surgery was performed in two patients, and one patient was conservatively treated. Symptoms resolved in all three patients. Conclusion: Endoscopic medial orbital decompression including removal of the medial floor of the orbit is a safe and effective procedure for treatment of thyroid eye disease. Navigation can be of valuable help to ensure complete resection of the bony walls. However, the majority of patients will need subsequent strabismus surgery, mainly due to significant increase of esotropia.
Lateral orbital wall decompression has been considered a safe and effective procedure for treatment of TED. Serious side-effects are infrequent, but in rare circumstances, even blindness may occur. Less serious side-effects are relatively common. Among others, a significant number of the patients developed temporal hollowing after the procedure. The patients must be informed about the possible complications before surgery.
Purpose The aim of this study is to identify biochemical inflammatory markers predicting the presence or risk of developing thyroid eye disease (TED) in patients with Graves’ disease (GD). Methods Patients with GD (n = 100, 77 females) were included from the National Norwegian Registry of Organ-Specific Diseases. Serum samples were analysed for 92 different inflammatory biomarkers using the proximity extension assay. Biomarker levels were compared between groups of patients with and without TED and healthy subjects (HS) (n = 120). Results TED was found in 36 of 100 GD patients. Significant (P < 0.05) differences in the levels of 52 inflammatory biomarkers were found when GD patients and HS were compared (42 elevated and 10 decreased). Out of the 42 elevated biomarkers, a significantly higher serum level of interleukin-6 (IL6) (P = 0.022) and macrophage colony-stimulating factor (CSF1) (P = 0.015) were found in patients with TED compared to patients without TED. Patients with severe TED also had significantly elevated levels of Fms-related tyrosine kinase 3 ligand (FLT3LG) (P = 0.009). Furthermore, fibroblast growth factor 21 (FGF21) was significantly increased (P = 0.008) in patients with GD who had no signs of TED at baseline but developed TED later. Conclusion We demonstrate an immunologic fingerprint of GD, as serum levels of several inflammation-related proteins were elevated, while others were decreased. Distinctly increased levels of IL6, CSF1, FLT3LG, and FGF21 were observed in TED, suggesting that these inflammatory proteins could be important in the pathogenesis, and therefore potential new biomarkers for clinical use.
ABSTRACT.Purpose: To examine the outcome of levator muscle recession with adjustable sutures for correcting upper eyelid retraction in thyroid eye disease. Methods: All patients treated at Haukeland University Hospital between 2001 and 2011 were invited to participate in a follow-up examination. Preoperative measurements were obtained from medical records. The following parameters were recorded: eyelid aperture, the distance from limbus to eyelid margin, vertical motility of the eyelid in up-and downgaze, lagophthalmos, proptosis, vertical motility of the eye, and strabismus. Symmetry and eyelid contour were evaluated from photographs. Results were categorized as good, acceptable or unacceptable. Results: Sixty-four out of a total of 80 patients attended the follow-up examination. Six were excluded from further analysis due to relapse of their thyroid eye disease with increased inflammation. Among the 58 remaining patients, a good result was observed in 34 patients, an acceptable result in 19 and an unacceptable result in 5. Lagophthalmos was seen in 30% of the lids preoperatively and in 7% postoperatively. A second procedure was performed in 13/80 patients, in 6 because of under-correction and in 7 because of ptosis. Wound infection occurred in 2 patients. Conclusion: Levator recession with adjustable sutures can be used to correct any degree of retraction. Good results can be obtained, but the procedure is timeconsuming, and patients must be informed about the risk for reoperation.
