Abstract
Diagnosis and therapy of orbital diseases is an interdisciplinary challenge, in which i.e. otorhinolaryngologists, ophthalmologists, radiologists, radiation therapists, maxillo-facial surgeons, endocrinologists, and pediatricians are involved. This review article describes frequent diseases which both, otolaryngologists and ophthalmologists are concerned with in interdisciplinary settings. In particular the inflammatory diseases of the orbit including orbital complications, autoimmunological diseases of the orbit including Grave´s orbitopathy, and primary and secondary tumors of the orbit are discussed. Beside describing the clinical characteristics and diagnostic steps the article focusses on the interdisciplinary therapy. The review is completed by the presentation of most important surgical approaches to the orbit, their indications and possible complications. The authors tried to highlight the relevant facts despite the shortness of the text.

[PMID: 37666483 DOI: 10.1016/j.jormas.2023.101616] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/14/2023] [Revised: 08/28/2023] [Accepted: 08/29/2023] [Indexed: 09/06/2023]
Abstract
OBJECTIVE There is currently no recommendation on the optimal surgical management for dysthyroid optic neuropathy (DON). The aim of this study is to systematically review the surgical management of DON and its outcome on visual acuity (VA). DATA SOURCES MEDLINE, Cochrane Library, and clinicaltrials.gov REVIEW METHODS: A systematic review of studies about the surgical management of DON was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Articles were included if preoperative and postoperative VA in logMAR (Logarithm of the Minimum Angle of Resolution) were available. RESULTS Fifteen articles were included in the study accounting for 669 orbits. The mean VA improvement was of 0.44 logMAR overall, 0.41 logMAR for 1-wall, 0.41 logMAR for 2-wall, and 0.55 logMAR for 3-wall decompressions. The mean reduction in exophthalmos was 4.9 mm overall, 4.3 mm for 1-wall, 4.54 mm for 2-wall, and 6.02 for 3-wall decompressions. The mean new onset diplopia (NOD) rate was 19.84% overall, 19,12% for 1-wall, 20.75% for 2-wall, and 19.83% for 3-wall decompressions. CONCLUSION The results are limited due to the high number of biases in the included studies. It seems that 3-wall decompression offers the best VA improvement and proptosis reduction although also the highest NOD and complications rate. Two-wall balanced decompression or 1-wall inferomedial decompression seems to be effective with less morbidity.

Abstract
PURPOSE Dysthyroid optic neuropathy (DON) is a sight-threatening complication of thyroid eye disease (TED). This review provides an overview of the epidemiology, pathogenesis, diagnosis, and current therapeutic options for DON. METHODS A literature review. RESULTS DON occurs in about 5% to 8% of TED patients. Compression of the optic nerve at the apex is the most widely accepted pathogenic mechanism. Excessive stretching of the nerve might play a role in a minority of cases. Increasing age, male gender, smoking, and diabetes mellitus have been identified as risk factors. Diagnosis of DON is based on a combination of ≥2 clinical findings, including decreased visual acuity, decreased color vision, relative afferent pupillary defect, visual field defects, or optic disc edema. Orbital imaging supports the diagnosis by confirming apical crowding or optic nerve stretching. DON should be promptly treated with high-dose intravenous glucocorticoids. Decompression surgery should be performed, but the response is incomplete. Radiotherapy might play a role in the prevention of DON development and may delay or avoid the need for surgery. The advent of new biologic-targeted agents provides an exciting new array of therapeutic options, though more research is needed to clarify the role of these medications in the management of DON. CONCLUSIONS Even with appropriate management, DON can result in irreversible loss of visual function. Prompt diagnosis and management are pivotal and require a multidisciplinary approach. Methylprednisolone infusions still represent first-line therapy, and surgical decompression is performed in cases of treatment failure. Biologics may play a role in the future.

Outcomes of Patients With Dysthyroid Optic Neuropathy Treated With Intravenous Corticosteroids and/or Orbital Decompression Surgery: A Systematic Review and Meta-analysis. J Clin Endocrinol Metab 2023; 108:2717-2727. [PMID: 37066814 DOI: 10.1210/clinem/dgad211] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/12/2023] [Revised: 03/24/2023] [Accepted: 04/12/2023] [Indexed: 04/18/2023]
Abstract
CONTEXT The level of evidence is low for the treatment of patients with dysthyroid optic neuropathy (DON) and there is no consensus on the treatment of DON with intravenous high-dose glucocorticoids (ivGC) or direct surgical decompression. OBJECTIVE To compare the efficacy of glucocorticoid treatment and orbital decompression (OD) in DON. DATA SOURCES PubMed, EMBASE, and Cochrane Library were searched along with other sources. STUDY SELECTION A total of 17 studies met the inclusion criteria. DATA EXTRACTION Standard methodological guidance of the Cochrane Handbook was used and data were independently extracted by multiple observers. The primary outcomes were the improvement of best corrected visual acuity (ΔBCVA). Secondary outcomes were proptosis reduction, change in diplopia, visual field defects, and intraocular pressure (IOP). DATA SYNTHESIS The ΔBCVA in the ivGC + OD group was improved 0.26 LogMAR more than in the ivGC group (P = .007). The ΔBCVA in the OD group was better than in the ivGC group (P = .008). Posttreatment proptosis in the ivGC + OD and OD groups were improved further by 3.54 mm and 3.00 mm, respectively, than in the ivGC group (P < .01). The mean deviation (MD) in the ivGC + OD group was improved by an additional 5.33 dB than in the ivGC group (P = .002). The IOP in the ivGC + OD group was improved further than in the ivGC group (P = .03). CONCLUSIONS Based on the results of the present meta-analysis, OD or ivGC + OD may be more effective in improving BCVA and MD and reducing proptosis compared with ivGC. Compared with ivGC alone, ivGC + OD is more effective in improving IOP than ivGC. Although this study improves the hierarchy of evidence in the treatment of DON, additional randomized controlled trials are needed to confirm this conclusion.

Abstract
PURPOSE To present the clinical features of thyroid-associated ophthalmopathy (TAO) with different CT types, and to report the outcomes of endoscopic orbital decompression combined with fat decompression (EOD-FD). PATIENTS AND METHODS Thirty-four patients with TAO who underwent EOD-FD between December 2020 and March 2022 in the Ophthalmology Department of Li Huili Hospital Affiliated with Ningbo University, were included in this retrospective interventional case series. Patients were categorized into two groups based on the results of computerized tomography (CT) scans: muscle expansion type and fat hyperplasia type. RESULTS Thirty-four TAO patients (55 eyes) were included in this study, and the mean age was 38.62 years (range 22-60 years). The average eye protrusion (EP) reduced from preoperative 23.20 mm to postoperative 19.66 mm (p < 0.0001). Mean intraocular pressure (IOP) decreased from 20.11 mmHg at baseline to 17.29 mmHg postoperatively (p < 0.0001), with a reduction of 2.84 mmHg (14.12%). Twenty cases of muscle expansion and fourteen cases of fat hyperplasia were definite by CT imaging. The mean IOP in the muscle expansion group was higher than that in the fat hyperplasia group (p < 0.05). Elevated intraocular pressure (IOP) occurred in 23 eyes (36.11%), and it was associated with extraocular muscle involvement, gender, and EP. In 3 cases of impaired vision, the mean best corrected visual acuity (VA) improved from 0.4 preoperatively to 0.84 postoperatively (p < 0.01). There were 8 cases with visual field (VF) damage and/or corneal epithelium damage, and all these damages were reversible. CONCLUSION In this study, we describe the clinical features and experience of EOD-FD in patients with TAO. EOD-FD is an effective technique in reducing IOP and proptosis, with a low incidence of postoperative diplopia.

Treatment Results of Endoscopic Transnasal Orbital Decompression for Graves' Orbitopathy-A Single-Center Retrospective Analysis in 28 Orbits of 16 Patients. J Pers Med 2022; 12:jpm12101714. [PMID: 36294853 PMCID: PMC9605419 DOI: 10.3390/jpm12101714] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2022] [Accepted: 10/12/2022] [Indexed: 12/02/2022] Open
Abstract
Graves’ orbitopathy (GO) is an extrathyroidal manifestation of Graves’ disease (GD), which can be associated with corneal ulcerations or optic neuropathy in severe forms. Transnasal endoscopic orbital decompression (TEOD) is a surgical procedure performed in order to decrease the intraorbital pressure by removing part of its bony borders in cases with excessive mass in orbit. The aim of this study was to present the results and evaluate the efficacy of TEOD for GO. The retrospective study included 28 orbits (16 patients) who underwent TEOD from 2017 to 2020. Outcome was evaluated based on visual acuity improvement, clinical activity score (CAS) decrease, proptosis, and intraocular pressure (IOP) reduction. A preoperative best-corrected visual acuity (BCVA) increased from 0.69 ± 0.385 (mean ± standard deviation) to 0.74 ± 0.332 (p = 0.17) postoperatively. CAS decreased in 15 orbits postoperatively. Proptosis decreased from 22.89 ± 1.873 mm to 21.25 ± 2.053 mm (p < 0.05). IOP decreased from a preoperative 16.11 ± 3.93 mmHg to 14.40 ± 3.27 mmHg (p < 0.05) postoperatively. In addition, postoperative relief of exposure keratitis was observed. The analysis of development of iatrogenic diplopia revealed increasing in degree of diplopia. TEOD shows rare complications, but significant improvements in BCVA, CAS, proptosis, and IOP.

Transnasal Endoscopic Orbital Decompression Combined with an Enhanced Recovery after Surgery Protocol in Graves Ophthalmopathy. J Ophthalmol 2022; 2022:6382429. [PMID: 36157679 PMCID: PMC9507727 DOI: 10.1155/2022/6382429] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2022] [Revised: 09/01/2022] [Accepted: 09/05/2022] [Indexed: 11/17/2022] Open
Abstract
Objective. Although enhanced recovery after surgery (ERAS) was shown to improve patients’ recovery after surgery and transnasal endoscopic orbital decompression has been associated with lesser risks of postoperative complications compared to other surgical techniques in treating Graves ophthalmopathy (GO), there are currently no clinical studies on the application of ERAS in transnasal endoscopic orbital decompression. This study aimed to investigate the potential effects of combining transnasal endoscopic orbital decompression with ERAS in the treatment of GO. Methods. A retrospective analysis was performed for 5 GO patients (10 eyes) treated with transnasal endoscopic orbital decompression from January 2021 to December 2021 at the Third Affiliated Hospital of Sun Yat-Sen University. All patients underwent ERAS, and the effects of ERAS on the postoperative complications and recovery of patients were evaluated. Results. Ophthalmological examination showed that GO patients had good correction of exophthalmos after surgery combined with ERAS. Specifically, the exophthalmos reduction in subjects was 0.9–2.1 mm, with a mean reduction of 1.23 mm. In addition, a visual acuity improvement of 0.15–0.4, with an average improvement of 0.23, was also observed. Further, the Scale of Quality of Life for Diseases with Visual Impairment (SQOL-DVI) showed that, compared with before surgery, the patients’ QOL was significantly improved 2 weeks after surgery. Before surgery, there were 2 patients with diplopia and blurred vision, and after postoperative adaptive exercise, the symptoms of these 2 patients disappeared after 6 months of follow-up. As for the other 3 patients, they had no diplopia or blurred vision after surgery. Conclusion. This observational study found that transnasal endoscopic orbital decompression might be effective in treating GO, and ERAS might be considered an important adjunct to improving perioperative care and postoperative recovery.

Abstract
OBJECTIVE Identify the impact of demographics and social determinants of health on surgical follow-up and complications after medial orbital wall decompression (MOWD) secondary to thyroid associated orbitopathy (TAO). METHODS Demographics and social determinants of health (age, sex, race, insurance status) for 46 patients undergoing MOWD secondary to TAO were correlated with post-operative compliance and surgical complications by chi-square analyses. RESULTS Among 46 patients, 23 were compliant with follow-up. There was no statistically significant difference between compliance and non-compliance based on age (60.25 vs 56.4, p = .41), sex (71.9 % female vs 85.7 % female, p = .31), race (65.6 % white vs 71.4 % white, p = .70) or insurance status (59.4 % private vs 42.9 % private, p = .30). Complications were noted in 50 % of patients of which sinus infection was most common (47.8 % of complications) and epistaxis rare (4.3 % of complications). No correlation was noted between development of complications and compliance (p = .20). Likewise, age, race and insurance status did not correlate with complications. CONCLUSION For patients undergoing MOWD, no correlations with compliance or complication rate were noted with age, sex, race, or insurance status. A larger cohort may be indicated to identify such patterns. The overall complication rate was 50 % and the increased number of visits may have economic impact. KEY POINTS This study provides a unique chance to assess demographic correlates of compliance and complication while controlling for surgeon preference. There was no association between sociodemographics and compliance or complications.

Abstract
OBJECTIVE To compare the indications, surgical techniques and outcomes for revision orbital decompression surgery for thyroid eye disease in open, endoscopic, and combined open and endoscopic approaches. METHODS A retrospective review of all revision orbital decompression procedures for thyroid eye disease from a single large academic institution over a 17-year period (01/01/2004-01/01/2021) was performed. Patient demographics, as well as indications and types of surgery were reviewed. Outcome measures included changes in proptosis, intraocular pressure, visual acuity and diplopia. RESULTS Thirty procedures were performed on 21 patients. There was a median of 9.4 months between primary orbital decompression and revision decompression surgery. There were 6 bilateral procedures, and 2 of these patients underwent additional revision surgeries due to decreased visual acuity with concern for persistent orbital apex compression or sight-threatening ocular surface exposure in the setting of proptosis. Twenty-five procedures were performed as open surgeries with 5 endoscopic/combined cases. Combined Ophthalmology/Otolaryngology surgery via combined open/endoscopic approaches was favoured for persistent orbital apex disease. Visual acuity remained preserved in all patients. The overall median reduction in proptosis was 2 mm and intraocular pressure change was 1 mmHg regardless of surgical approach. The overall rate of new onset diplopia after surgery was 15%. These patients had open approaches. All endoscopic/combined approach patients had pre-existing diplopia. There were no statistically significant differences between the open and endoscopic/combined groups in regard to change in visual acuity, reduction in proptosis or intraocular pressure. CONCLUSION Revision orbital decompression is an uncommon procedure indicated for those patients with progressive symptoms despite previous surgery and intensive medical management. Both endoscopic and non-endoscopic techniques offer favourable outcomes with respect to visual acuity, decrease in intraocular pressure, and improvement in proptosis and overall lead to a low incidence of new onset diplopia. LEVEL OF EVIDENCE Level IV.

Abstract
Purpose To evaluate the efficacy and safety of endoscopic orbital decompression in patients with Graves' orbitopathy. Patients and Methods This is a prospective study in Hanoi Medical University and a Military Hospital from December 2017 to December 2018. Twenty-eight orbits of fifteen patients were undergoing endoscopic orbital decompression for Graves' orbitopathy. Indications for surgery were proptosis in twenty-two orbits and compressive optic neuropathy in six orbits. The outcome measures were proptosis reduction, visual acuity, visual field test and diplopia. Post-operative complications including cerebrospinal fluid leakage, haemorrhage, lacrimal duct impairment, worsening diplopia, sinusitis and cellulitis were collected. Results The mean proptosis reduction was 2.23 mm. Visual acuity and medium deviation in the Humphrey visual field were significantly improved in four of six eyes with compressive optic neuropathy. There was one patient with intra-operative excessive bleeding which resolved without affecting visual outcome. Post-operatively, two patients developed a new onset of diplopia and two others worsened diplopia; three have already undergone successful strabismus surgery and moderate proptosis reduction. Conclusion Endoscopic orbital decompression surgery was effectively and safely to manage compressive optic neuropathy of Graves' orbitopathy and moderately reduce proptosis in a group of Vietnamese patients.
