RESUMEN
PURPOSE: To assess the clinical outcomes of fat repositioning via supraperiosteal dissection with midface lift for correction of tear trough deformity in a large Asian patient population. METHODS: Retrospectively review 1152 Asian patients who underwent fat repositioning to the supraperiosteal plane with a midface lift between 2005 and 2022. Surgical technique, postoperative course, and complications were recorded. At the 6-month postoperative follow-up, the degree of patient satisfaction was assessed. RESULTS: A total of 2304 eyes from 1152 patients with an average follow-up of 10 months. These procedures were performed using a transforniceal approach in 185 patients (16%) or a transcutaneous skin excision approach in 967 patients (84%). Among the patients who underwent the transcutaneous technique, seven individuals (0.6%) experienced effective treatment of lower lid ectropion through lateral tarsal strip procedures. Nine patients (0.7%) required revision surgery to address the remaining lateral fat pad due to inadequate lateral orbital fat excision during the initial procedure. At the 6-month follow-up, most patients reported a high level of satisfaction, with 800 patients (78%) expressing extreme satisfaction and 196 patients (19.1%) reporting satisfaction with the improvement in their appearance. No one reported facial numbness, lower eyelid or cheek paralysis, newly developed diplopia or granuloma formation. CONCLUSION: The procedure of fat repositioning involving supraperiosteal dissection and a midface lift, whether performed using a transforniceal approach or a transcutaneous skin excision approach, in lower eyelid blepharoplasty proves to be a secure and auspicious surgical technique for rectifying tear trough deformity and attaining a pleasing aesthetic outcome.

BACKGROUND: To investigate the efficacy and predictability of Muller's muscle-conjunctival resection (MMCR) with different lengths of tarsectomy for the treatment of unilateral mild-to-moderate blepharoptosis. METHODS: A retrospective study of patients who underwent MMCR with tarsectomy for unilateral mild-to-moderate blepharoptosis between January 2016 and December 2019 was performed. Individuals with adequate photographic documentation and good levator function were included. Data on age, gender, surgical designs, pre-operative and post-operative marginal reflex distance 1 (MRD1) and tarsal platform show (TPS), and complications were retrieved. RESULTS: Sixty patients underwent 8-mm MMCR with 1- or 2-mm tarsectomy; 53 patients (88.3%) showed postoperative symmetry of MRD1 within 1 mm. The average postoperative improvement in MRD1 was 2.15 ± 0.8 mm. Thirty-two patients received 8-mm MMCR with 1-mm tarsectomy (group 1), and 28 patients underwent 8-mm MMCR with 2-mm tarsectomy (group 2). In group 1, postoperative symmetry rate was 90.6%, and the mean elevation of MRD1 was 1.66 ± 0.6 mm. In group 2, postoperative symmetry rate was 85.7%, and the mean elevation of MRD1 was 2.72 ± 0.6 mm. Both groups showed postoperative symmetry of TPS and significant improvement in eyelid position (p < 0.0001). No postoperative complication was noted, and no secondary surgery was needed. CONCLUSIONS: MMCR with tarsectomy was proven to be a safe, rapid, and effective method for patients with mild-to-moderate ptosis. Predictability and symmetry of the outcome were statistically confirmed. We further suggest a 2.1-mm expected MRD1 elevation as a cut point for choosing between 1- or 2-mm tarsectomy.

Graves' ophthalmopathy (GO), which is characterized by orbital tissue inflammation, expansion, and fibrosis, is the ocular manifestation in 25% to 50% of patients with Graves' disease. As the pathology of GO is driven by autoimmune inflammation, many proinflammatory cytokines/chemokines, including TNF-α, IL-1ß, IL-6, and CCL20, are crucial in the pathogenesis of GO to activate the orbital fibroblasts. Cysteine-rich protein 61 (CYR61), which is known to regulate cell proliferation, adhesion, and migration, plays a proinflammatory role in the pathogenesis of many inflammatory diseases, such as rheumatoid arthritis. CYR61 was considered a potential biomarker of GO in recent studies. Statins, which are cholesterol-lowering drugs, were found to reduce the risk of GO, probably through their anti-inflammatory and immunomodulatory effects. In this study, we established a link between CYR61 and statins in the pathogenesis and potential treatment for GO. Firstly, our data showed the overexpression of CYR61 in the orbital tissue (n = 4) and serum specimens (n = 6) obtained from the patients with inactive GO. CYR61 could induce the production of IL-6 and CCL20 in cultured GO orbital fibroblasts. The expression of CYR61 in cultured GO orbital fibroblasts was upregulated via TNF-α stimulation. Secondly, we pretreated cultured GO orbital fibroblasts using simvastatin, a statin, followed by TNF-α stimulation. The data revealed that simvastatin could inhibit TNF-α-induced CYR61 expression by modulating the activity of transcription factor FoxO3a. Our results provided insights into some cellular mechanisms that may explain the possible protective effects of simvastatin against the development of GO.

BACKGROUND: Orbital compartment syndrome (OCS) is an ocular emergency that can severely threaten the visual potential. The most common etiologies include facial trauma-related orbital wall fractures and postoperative bleeding within the orbit. Nontraumatic cases were also reported sporadically, although they are rare. The orbital volume limits the compliance to expand when space-occupying lesions develop. Both direct compression of the optic nerve and depleted perfusion from elevated intraorbital pressure subsequently lead to ischemic optic neuropathy and vision loss. CASE REPORT: A 74-year-old man experienced headache, bulging left eye, dull pain, vision loss, nausea, and vomiting within 1 day. Computed tomography and magnetic resonance imaging revealed a heterogeneous mass extending from the orbital apex and connected with the ophthalmic vein. Lateral canthotomy and cantholysis were performed at bedside for emergent orbital decompression. The proptosis and pain relieved after surgery, but visual loss remained irreversible. Surgical exploration was conducted and pathology proved the diagnosis of varix of the ophthalmic vein with thrombosis. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Clinicians should be aware of the presentation of OCS and perform timely orbital decompression, which could reverse visual impairment. These patients might also benefit from immediate consultants with ophthalmologists and radiologists.

PURPOSE: To describe the prognostic factors and survival outcomes in patients who underwent orbital exenteration surgery at a tertiary center over a 20-year period. METHODS: This institutional retrospective study reviewed all patients who underwent orbital exenteration between January 1999 and January 2019 at Department of Ophthalmology, National Taiwan University Hospital. Patient demographics, tumor site, histopathology, status of surgical margins, additional resection, local recurrence, metastases, survival, and treatment data were recorded. Log-rank tests were used to verify the difference in survival curves among various potential prognostic factors. RESULTS: Thirty patients (27 with malignancy, 1 with hybrid neurofibroma/schwannoma, and 2 with mucormycosis) were included. Malignant melanoma (n = 11) and sebaceous gland carcinoma (n = 8) were the most common indications for exenteration. Survival rates were 83% at 1 year, 42% at 3 years, and 33% at 5 years. Among patients with malignancies, 71% patients had clear margins after exenteration. All the incidences of local recurrence developed in the first 2 years postoperatively. Postoperative survival was significantly related to lymphovascular invasion (p = 0.018), but was independent from surgical margins, presence of metastasis, local recurrence, or perineural invasion. CONCLUSION: We found worse prognosis with positive lymphovascular invasion. Although not significant, malignant melanoma showed poorer survival times compared to sebaceous gland carcinoma. Close follow-up, especially in the first 2 years after orbital exenteration, is crucial to identify disease recurrence.

BACKGROUND/PURPOSE: To verify the staging system of the American Joint Committee on Cancer (AJCC) 8th edition for uveal melanoma, and to propose the prognostic factors of uveal melanoma by a 45-year cohort study. METHODS: We collected patients who underwent operation with pathological proof from 1973 to 2017. The demographic data including gender, age, laterality, metastatic pattern, and histopathology type were recorded. The predictability for survival and monotonicity of gradients of the AJCC 8th edition were evaluated. The prognostic factors for survival were analyzed by univariate and multivariate analysis. RESULTS: A total of 72 patients were collected. The median age was 55 year-old (range 24-100). No specific gender predilection was revealed in our study. About 75.9% of metastases events happened in the first five-year of follow-up, and hepatic involvement was the most common. By the AJCC 8th edition, the distribution for stage I: II: III was 8 (11.1%), 37 (51.4%), and 27 (37.5%). The prognostic staging groups manifested fair predictability and monotonicity of gradients for survival outcome. The tumors with epithelioid cell type and ciliary body involvements had higher tumor-related mortality. CONCLUSION: The AJCC 8th edition prognostic staging groups for outcome prediction was validated. Periodic screening for metastases should be more frequent in the first five-year follow-up. The tumors with epithelioid cell pattern and ciliary body involvements were at risk of higher tumor-related mortality in Taiwanese patients.

PURPOSE: Current outcome measures do not adequately address the esthetic aspect of the surgical outcome of anterior blepharotomy for Graves' ophthalmopathy. This study aims to highlight the role of tarsal platform show (TPS) in optimizing the esthetic outcome of graded full-thickness anterior blepharotomy for dysthyroid upper eyelid retraction in an ethnic Chinese population. METHODS: The records of patients with Graves' ophthalmopathy who underwent anterior blepharotomy for upper eyelid retraction over a period of 30 months were retrospectively reviewed. RESULTS: Fifty-five patients (77 eyelids) with upper eyelid retraction underwent anterior blepharotomy. A statistically significant decrease in marginal reflex distance (MRD1) and lagophthalmos and significant increase in TPS following anterior blepharotomy was observed. A significantly higher proportion of patients who underwent unilateral anterior blepharotomy had TPS asymmetry post-operatively as compared to the bilateral group (p < 0.001). Using logistic regression, the study found that for every 1-mm change in MRD1, there was approximately a 1.045-mm change in TPS. The mean percentage increase in TPS observed in our study was 303.1 ± 191% due to the low pre-operative TPS seen in Asian patients. CONCLUSIONS: To achieve the most ideal surgical outcome in graded full-thickness anterior blepharotomy, the surgeon will need to consider not only eyelid height but also the subsequent TPS change. The surgeon needs to be mindful of the relationship between MRD1 change and TPS change to optimize esthetic outcome as well as symmetry. Special considerations need to be taken in unilateral cases as well as patients with low pre-operative TPS.

BACKGROUND: Epibulbar complex choristoma, a rare congenital epibulbar tumor, has many diverse forms. Reviewing the literature, it can present clinically as either a circumferential or isolated epibulbar mass, limbal tumor, lateral canthal mass, aggregate of ectopic cilia in the upper eyelid, eyelid mass mimicking chalazion, or lacrimal caruncle mass. The management depends on the extent of involvement, the risk of amblyopia, and cosmetic concerns. Here, we report an atypical presentation of epibulbar complex choristoma with simultaneous eyelid involvement. CASE PRESENTATION: A 1-month-old full-term boy was brought to our clinic with congenital epibulbar mass of the right eye with simultaneous eyelid involvement. Dilated fundus examination was unremarkable. Survey for linear nevus sebaceous Jadassohn was negative. Due to concerns of possible amblyopia and cosmetics, lamellar keratectomy, sclerotomy, and conjunctivoplasty were performed to remove the epibulbar lesion. The eyelid defect was reconstructed with 6-0 Vicryl sutures. Histopathological examination reported complex choristoma. Upon three-year follow-up, low astigmatism and favorable cosmetics results were achieved. CONCLUSIONS: Congenital complex choristoma can present clinically as an epibulbar mass with eyelid involvement. The management depends on the extent of involvement, the risk of amblyopia, and cosmetic concerns. The method of eyelid reconstruction should be tailored according to the residual eyelid defect.

BACKGROUND/PURPOSE: To compare the outcomes of strabismus surgery in patients with Graves' ophthalmopathy (GO) who had undergone bone removal orbital decompression (BROD) or fat removal orbital decompression (FROD) with those who had not undergone any orbital decompression. METHODS: The records of patients with GO who underwent strabismus surgery over a period of 66 months were retrospectively reviewed. RESULTS: Eighty-nine patients with a mean age of 55.1 ± 11.9 years were identified in this study. Twenty-two patients had prior BROD, 20 patients had prior FROD and 47 patients had no orbital decompression. Patients who had prior orbital decompression had an average of 1.6 strabismus surgeries per patient which was significantly higher compared to 1.2 strabismus surgeries in patients who had no orbital decompression (p = 0.02). The overall success rate of strabismus surgery was 68.2%, 80.0% and 80.9% following BROD, FROD and no orbital decompression respectively. The overall success rate of strabismus surgeries in patients with GO was 61% after the first surgery and 78% after the final surgery. CONCLUSION: The management of strabismus in GO is complex and difficult. Prior orbital decompression is associated with more strabismus surgeries per patient with a trend towards a lower success rate for strabismus surgery. FROD is comparable to BROD with regards to its effects on the outcome of subsequent strabismus surgeries.

PURPOSE: To describe and discuss rare and benign conditions of subconjunctival orbital fat herniation that may mimic adipocytic neoplasm. METHODS: Sixteen eyes of 13 patients with subconjunctival orbital fat herniation were included. They all underwent transconjunctival excision owing to cosmesis, discomfort, or suspicion of malignancy. Histopathologic examination, postoperative complications, and recurrent conditions were analyzed. RESULTS: Eleven male and two female patients were included. The lesion was unilateral in 10 and bilateral in 3 cases. Excision was performed via conjunctival wound and removing the prolapsed orbital fat. The conjunctiva was then closed with two to three interrupted sutures. All the histopathologic specimens revealed Lochkern cells, floret cells, and mature adipocytes separated by fibrovascular septae without hyperchromatic cells, consistent with subconjunctival herniated orbital fat. All the patients were treated successfully with transconjunctival excision without recurrence at an average follow-up of 10.6 months (range, 6 to 16 months). CONCLUSIONS: Prolapse of subconjunctival orbital fat is an uncommon entity of intraorbital masses and may mimic adipocytic neoplasm. It is usually associated with a dehiscence in the Tenon capsule. Surgical excision is indicated and pathologic evaluation is necessary if any malignancy is suspected.

BACKGROUND/PURPOSE: This study investigated the clinical significance of quality of life (QOL) related specifically to Graves' ophthalmopathy (GO) among Taiwanese patients. METHODS: We recruited 271 patients with GO who were seen at the National Taiwan University Hospital Department of Ophthalmology from September 1, 2012 to November 30, 2012. Patients completed the GO-QOL Questionnaire. The main outcome measures were the scores on two GO-QOL subscales: visual functioning and appearance. The percentage of responses occurring at the maximum and minimum values was also calculated to assess possible ceiling and floor effects, respectively. RESULTS: The mean ± standard deviation QOL scores for the subscales of visual functioning and appearance were 58.39 ± 25.17 and 54.45 ± 20.52, respectively. The scores for both subscales were significantly correlated with disease severity and clinical activity scores (all p < 0.05). The QOL scores for the appearance subscale were significantly correlated with the degree of diplopia (p < 0.05). No significant ceiling or floor effects were observed for either subscale of the GO-QOL. CONCLUSION: Scores on the Chinese (Taiwan) version of the GO-QOL were strongly correlated with disease severity and clinical activity. The GO-QOL is a simple and practical tool that can be used to evaluate health-related QOL in GO patients.

BACKGROUND/PURPOSE: To investigate the bulbar conjunctival changes in patients with Graves' ophthalmopathy (GO) using in vivo confocal microscopy. METHODS: A total of 15 GO patients and 15 control patients were recruited. Images of the superior site and temporal bulbar conjunctivas were taken by the Heidelberg Retina Tomograph/Rostock Corneal Module. The conjunctival thickness and cell density of superior epithelium, basal epithelium, Langerhans cells, and goblet cells were analyzed. Conjunctival impression cytology was performed to assess the grading of squamous metaplasia of the conjunctival epithelium. RESULTS: The superficial epithelial cell density in the superior bulbar conjunctiva of the GO group was 856.93 ± 461.68 cells/mm(2), which was significantly lower than that in the control group (1581.13 ± 556.34 cells/mm(2); p = 0.002). However, the difference in superficial epithelial cell density in the temporal bulbar conjunctiva between the two groups was not statistically significant. No significant differences in conjunctival thickness and the basal epithelial cell density were noted between the two groups. Increased Langerhans cell density and reduced goblet cell density were noted in the GO group. Impression cytology of the conjunctival epithelium revealed significantly higher degree of squamous metaplasia in the GO group. The superficial epithelial cell density in the upper bulbar conjunctiva showed negative correlation with marginal reflex distance in the GO group. CONCLUSION: GO patients suffered from more severe bulbar conjunctival damage and inflammation with the superior site than the temporal site. In vivo confocal microscopy can be a rapid and noninvasive tool for the quantitative evaluation of ocular surface changes in patients with GO.

BACKGROUND: Sebaceous tumors are adnexal neoplasms showing sebocytic differentiation. They range from benign to malignant and are associated with Muir-Torre syndrome (MTS). Several clinical and histopathological features associated with MTS have been described. Sebaceous tumors with an overlying cutaneous horn are extremely rare. METHODS: Hematoxylin and eosin-stained slides were retrospectively reviewed to identify sebaceous tumors with marked hyperkeratosis, a condition that is often associated with cutaneous horns. Clinical correlation and mismatch repair protein immunohistochemical studies were then conducted. RESULTS: Four tumors from three patients were identified in our archive. Three were classified as sebaceous adenomas, and the fourth was considered as a borderline sebaceous tumor favoring well-differentiated sebaceous carcinoma. All cases showed loss of expression of mismatch repair proteins (three tumors from two patients exhibited lost expression of MSH2 and MSH6, and the fourth exhibited lost expression of MLH1 and PMS2). Additionally, one patient presented characteristic clinical manifestations of MTS, including multiple sebaceous adenomas and visceral carcinomas. CONCLUSIONS: We suggest that extraocular well-differentiated sebaceous neoplasms with overlying cutaneous horns may be an indication of underlying mismatch repair protein deficiency and potential MTS. This distinctive morphology might be an exaggerated combination of other features associated with MTS, i.e. keratoacanthoma-like architecture and extensive holocrine secretion.

PURPOSE: To report the efficacy of a full-thickness skin graft (FTSG) for the reconstruction of a contracted eye socket. DESIGN: A retrospective, non-comparative, interventional case series. METHODS: This was a retrospective review of patients with a contracted eye socket who underwent socket reconstruction using a post-auricular FTSG from 2001 to 2011 at the National Taiwan University Hospital. The postoperative results including prosthetic fitting, the cosmetic result, and eyelid function were assessed. RESULTS: There were 11 male and 15 female patients, with a mean age of 52.3 ± 15.6 years (range 21 to 76). The duration of the socket contracture varied from three months to three years (average 7.4 ± 8.1 months). The severity of the socket contracture ranged from grade 2 to grade 4, based on Tawfik's classification. The mean follow-up time was 35.7 ± 9.6 months. After socket reconstruction, using a post-auricular FTSG, 96% of the cases (25 of 26) demonstrated a successful prosthetic fitting and a satisfactory cosmetic outcome. Both good eyelid function and a stable fornix depth were maintained during the follow-up time. One case received a second socket reconstruction three months after the first operation, using a FTSG, because of an inadequate lateral fornix. The final result was satisfactory. There were no serious complications, but a granuloma formed in one case, and there was prolonged discharge in one case. CONCLUSIONS: The reconstruction of a contracted eye socket using a post-auricular FTSG is an effective method with a high success rate, which causes less discomfort to donor sites and results in few complications.

BACKGROUND/PURPOSE: Hemangiopericytoma is a very rare orbital tumor. The purpose of this study was to report the clinical and histopathological features of six cases of orbital hemangiopericytoma in an Asian population. METHODS: Clinical and histopathological features were reviewed in six patients who were histopathologically confirmed as having primary orbital hemangiopericytoma in National Taiwan University Hospital between May 2001 and December 2010. RESULTS: Among the six cases who were diagnosed as having primary orbital hemangiopericytoma, all lesions were reported as vascular tumors and featured branching "staghorn appearance" vessels. All patients, including one male and five females, presented with progressive proptosis and some associated symptoms such as extraocular motility limitation with diplopia, displacement of the globe, afferent pupillary defect, congested vessels of conjunctiva, or decreased visual acuity. On computed tomography, the orbital tumors tended to manifest as circumscribed masses with homogeneous medium-to-high enhancement with contrast studies. All six patients received surgical treatments, and four of them had additional radiotherapy. Three patients had recurrence after surgeries, and one of them had multiple metastases to lung and liver. All patients were still alive after a follow-up period of 5-10 years. CONCLUSION: Orbital hemangiopericytoma has malignant potential, which may lead to local recurrence and/or metastasis. Histopathological findings alone are insufficient to predict the behavior of this tumor. Therefore, both clinical and histopathological findings are important to evaluate the treatment outcomes. Total excision accompanied with radiotherapy is suggested and long-term follow-up is required.

ABSTRACT: To propose a needle aspiration technique for the surgical removal of orbital cavernous hemangioma. In this retrospective case series, we enrolled 13 patients with orbital cavernous hemangioma, who underwent excisional surgery assisted with needle aspiration technique from June 2013 to April 2022. Preoperative symptoms, clinical examination, and imaging features were recorded. Surgical outcomes, including the improvement of visual acuity, proptosis, and ocular motility, were assessed. Postoperative complications were also reported. There were 11 female and two male patients, with a mean age of 50.2 ± 8.0 years (range: 38-61 years). The most common symptom was proptosis (12 cases, 92%), followed by blurred vision (6 cases, 46%). The diameter of the lesions was between 1.8 and 3.2 cm on preoperative imaging. The surgical approaches included sub-brow orbitotomy in 11 patients and the inferior transconjunctival approach in two cases. All the tumors were removed successfully after needle aspiration of 1-3 cc of intralesional blood to reduce the tumor size. Preoperative proptosis, blurred vision, and diplopia improved after the surgery in all cases. There were no serious complications or recurrence of orbital hemangioma. The study presented an effective application of the needle aspiration technique in the surgical management of orbital cavernous hemangioma. Such an innovative method can bring significant benefits, especially for those with large cavernous hemangioma within the deep orbital region.
RESUMEN
OBJECTIVE: This study aims to assess morphometric variations in bony nasolacrimal ducts (BNLDs) and sinonasal anatomy in Asian patients with unilateral primary acquired nasolacrimal duct obstruction (PANDO) through computed tomography (CT). METHODS: We enrolled 34 patients with unilateral PANDO who underwent endoscopic dacryocystorhinostomy, alongside 34 age- and sex-matched control patients without documented epiphora complaints. We compared BNLD and sinonasal parameters on CT images between the affected and unaffected sides of PANDO patients and the control group. RESULTS: The entrance area of the BNLD was larger on the affected side of unilateral PANDO patients compared to both the unaffected side (pâ¯=â¯0.012) and the control group (pâ¯=â¯0.046). The open angle in the coronal plane was greater on both the affected (pâ¯=â¯0.044) and unaffected side (pâ¯=â¯0.028) than in the control group. Minimal area and distal area in the axial plane showed no differences among the 3 groups. Paranasal parameters did not differ between the study and control groups. More patients in the study group had superiorly located nasal septum deviation than the control group (pâ¯=â¯0.048). A trend suggested that more patients in the study group had anteriorly located nasal septum deviation than the control group (pâ¯=â¯0.056), although not reaching statistical significance. CONCLUSION: The increased angular tilt in PANDO patients could impede fluid drainage from a fluidics standpoint. The larger BNLD area on the affected side reflects inflammation-induced osteolysis. Additionally, sinonasal variations, particularly nasal septum deviation at the anterior and superior half, have been identified as contributing to a higher risk of PANDO.
RESUMEN
PURPOSE: This study aims to evaluate the long-term outcomes of inferomedial orbital wall decompression (IMOD) in Graves' ophthalmopathy (GO). METHODS: A retrospective review of 422 eyes of 226 patients with GO-related cosmetically disfiguring proptosis (COS), dysthyroid optic neuropathy (DON), or exposure keratopathy (EXP) who received IMOD from 1989 to 2020 was conducted. Hertel value (HE) and corrected visual acuity (CVA) were evaluated at baseline and regularly thereafter. Proptosis recurrence, diplopia, and adjuvant surgeries were assessed. Complete success was defined as proptosis reduction over 2 mm without recurrence and improved diplopia. Partial success was defined as proptosis reduction without recurrence but with persistent or new-onset diplopia, and failure as proptosis recurrence. RESULTS: After follow-up for 40.1 ± 39.6 months (range, 6-239 months), 236 eyes (55.9%) achieved complete success, 175 eyes (41.5%) achieved partial success, and 11 eyes (2.6%) had failure. Significant CVA improvement was observed in both DON and COS groups (P < 0.001 and P = 0.045, respectively). Average proptosis reduction was 5.2 ± 2.2 mm, with a significant increase of 0.5 mm after long-term follow-up (P < 0.001). Incidence of proptosis recurrence was 2.6%. Surgical success rate of COS group was positively correlated with preoperative HE. CONCLUSION: IMOD demonstrated excellent success rate in all three subgroups with a low proptosis recurrence rate and improved visual outcome in both DON and COS groups. Delayed proptosis reduction effect of IMOD may result in delayed-onset asymmetry, especially in the unilateral group.

PURPOSE: Persistent diplopia after rectus muscle myectomy is not uncommon but challenging in patients with Graves' ophthalmopathy. We investigated the role of lateral rectus muscle resection for patients after medial rectus muscle myectomy in Graves' ophthalmopathy. METHODS: We retrospectively reviewed and collected data from patients with persistent diplopia after medial rectus muscle myectomy for Graves' ophthalmopathy who underwent unilateral or bilateral lateral rectus muscle resection. The eyeball deviations in the primary and reading positions before and after the operation were measured. A successful surgical outcome was defined as having less than five prism diopters (PD) in the primary gaze and functional binocular vision in the central 30° field postoperatively. RESULTS: A total of fifteen patients were included (mean post-myectomy deviation: 35.9 PD, range: 14 to -75 PD). The lateral rectus muscle resection after medial rectus muscle myectomy achieved an 80.0% success rate, with one patient over-corrected and two patients under-corrected. CONCLUSIONS: The lateral rectus muscle resection is an effective and predictable procedure for managing residual esotropia in Graves' ophthalmopathy patients who have previously undergone medial rectus muscle myectomy.
RESUMEN
INTRODUCTION: Graves' ophthalmopathy (GO) is an autoimmune inflammatory disorder observed in a substantial proportion of patients with Graves' disease (GD), with debilitating symptoms of disfiguring, periorbital pain, dry eyes, diplopia, and even visual disturbances. Previous studies involving Western populations have noted discrepancies in risk factors for GO. Therefore, this study aimed to determine the risk factors for GO development and the protective effect of statins in newly diagnosed patients with GD in Taiwan. METHODS: This retrospective case-control study was based on a tertiary center cohort involving patients with GD diagnosed between 2010 and 2019 at the National Taiwan University Hospital (n = 11,035). Patients who were diagnosed or treated elsewhere, had been followed up for less than 6 months or were with a diagnosis of orbital tumor were excluded. Overall, 3578 patients with GD met the inclusion criteria. Univariate and multivariate logistic regression analyses were used to ascertain the odds ratio (OR) of developing GO, with adjustment for sociodemographic factors, interventions for managing GD and thyroid hormone levels, to determine protective and risk factors for GO. RESULTS: In our multivariate model, the use of statins reduced the risk of GO development (OR 0.2; 95% confidence interval [CI] 0.08-0.50; p < 0.001). Thyroid dysfunction including hyperthyroidism (OR 4.2; 95% CI 2.97-5.88; p < 0.001) and hypothyroidism (OR 4.7; 95% CI 3.02-7.19; p < 0.001) was associated with an increased risk of developing GO. Smoking status and lipid profile were not risk factors in our cohort. CONCLUSION: In newly diagnosed patients with GD, the use of statins decreased the risk of developing GO by 80%, whereas serum lipid levels were not considered risk factors. Further nationwide population-based studies may help clarify the differences in risk factors between various ethnic groups. TRAIL REGISTRATION: This trial was approved by the Research Ethics Committee of National Taiwan University Hospital (202202066RINC), retrospectively registered from January 1, 2010 to December 31, 2019.
