Inflammation and Fibrosis in Orbital Inflammatory Disease: A Histopathologic Analysis.

PURPOSE: The purpose of this study was to compare the histopathologic inflammation and fibrosis of orbital adipose tissue in orbital inflammatory disease (OID) specimens. METHODS: In this retrospective cohort study, inflammation, and fibrosis in orbital adipose tissue from patients with thyroid-associated orbitopathy (TAO), granulomatosis with polyangiitis (GPA), sarcoidosis, nonspecific orbital inflammation (NSOI), and healthy controls were scored by 2 masked ocular pathologists. Both categories were scored on a scale of 0 to 3 with scoring criteria based on the percentage of specimens containing inflammation or fibrosis, respectively. Tissue specimens were collected from oculoplastic surgeons at 8 international centers representing 4 countries. Seventy-four specimens were included: 25 with TAO, 6 with orbital GPA, 7 with orbital sarcoidosis, 24 with NSOI, and 12 healthy controls. RESULTS: The mean inflammation and fibrosis scores for healthy controls were 0.0 and 1.1, respectively. Orbital inflammatory disease groups' inflammation (I) and fibrosis (F) scores, formatted [I, F] with respective p -values when compared to controls, were: TAO [0.2, 1.4] ( p = 1, 1), GPA [1.9, 2.6] ( p = 0.003, 0.009), sarcoidosis [2.4, 1.9] ( p = 0.001, 0.023), and NSOI [1.3, 1.8] ( p ≤ 0.001, 0.018). Sarcoidosis had the highest mean inflammation score. The pairwise analysis demonstrated that sarcoidosis had a significantly higher mean inflammation score than NSOI ( p = 0.036) and TAO ( p < 0.0001), but no difference when compared to GPA. GPA had the highest mean fibrosis score, with pairwise analysis demonstrating a significantly higher mean fibrosis score than TAO ( p = 0.048). CONCLUSIONS: Mean inflammation and fibrosis scores in TAO orbital adipose tissue samples did not differ from healthy controls. In contrast, the more "intense" inflammatory diseases such as GPA, sarcoidosis, and NSOI did demonstrate higher histopathologic inflammation and fibrosis. This has implications in prognosis, therapeutic selection, and response monitoring in orbital inflammatory disease.

A Case of Tofacitinib-Induced Lymphomatoid Papulosis With Ocular Involvement.

ABSTRACT: Janus kinase (JAK) inhibitors are being prescribed with increasing regularity in dermatology. We report on a patient who initiated treatment with tofacitinib for refractory erythema elevatum diutinum and subsequently developed a novel cutaneous outbreak characterized by firm violaceous papules on the trunk and extremities along with conjunctival injection and periorbital inflammation. Biopsy of affected tissue from both the cutaneous and ophthalmologic sources demonstrated increased numbers of CD30+ large atypical cells amid a mixed inflammatory cell infiltrate, consistent with lymphomatoid papulosis. A review of the literature reveals a plausible mechanism for the induction of persistent JAK signaling in the presence of a JAK inhibitor. We discuss this mechanism in depth because it pertains to this patient and recommend continued vigilance with the use of these immunologic agents.

Hypervirulent Streptococcus agalactiae septicemia in twin ex-premature infants transmitted by breast milk: report of source detection and isolate characterization using commonly available molecular diagnostic methods.

BACKGROUND: Group B Streptococcus (GBS) infections caused by Streptococcus agalactiae is a leading cause of meningitis and sepsis in neonates, with early-onset GBS symptoms emerging during the first week of life and late-onset occurring thereafter. Perinatal transmission of GBS to the neonate through the birth canal is the main factor associated with early-onset neonate infections, while less is understood about the source of late-onset infections. METHODS: In this report we describe a case of twin ex-premature infants who presented one month after birth with GBS septicemia. The mother had been appropriately screened at gestational age 35-37 weeks and laboratory methods failed to detect GBS colonization by culture or clinical molecular methods. In attempts to identify and isolate the source of GBS infection, additional surveillance swabs were collected from the mother at the time of neonate admission. Culture and a commercially available, FDA-cleared molecular PCR assay were performed. RESULTS: No GBS was detected from swabs collected from the perianal, thigh/groin or axillary areas. However, expressed breast milk and swabs from the breastmilk pump were positive by both methods. Since simultaneous culture and molecular methods which used breastmilk as a source were performed, investigators ascertained the limit of detection for GBS in breastmilk. The limit of detection was determined to be tenfold lower than that of LIM-broth enriched cultures-the FDA-approved source. Subsequent whole genome sequencing (WGS) analysis of isolates recovered from breastmilk and blood cultures from the infants demonstrated all strains were related and characterized as ST-452. Both infants responded very well to treatment and continued to have no related events or concerns at the two-year follow up appointment. CONCLUSIONS: Strain type 452 (capsular type IV) has recently emerged as a hypervirulent strain and has previously been documented as causing GBS infections in elderly populations. Antibiotic therapy resolved both mother and infant infections. Subsequent testing for the presence of GBS in breastmilk samples also showed an absence of bacteria. This is the first report of infant twins late-onset GBS infections caused by the hypervirulent S. agalactiae ST-452 with breastmilk as the source.

Predictability of the Phenylephrine Test With Regard to Eyelid Skin Appearance in Patients Who Undergo Müller Muscle-Conjunctival Resection Without Blepharoplasty.

PURPOSE: To evaluate the ability of preoperative phenylephrine testing to predict postoperative upper eyelid tarsal platform show in patients undergoing Müller muscle-conjunctival resection (MMCR) ptosis repair without concurrent blepharoplasty. METHODS: A retrospective chart review was performed on 52 eyelids of patients who underwent MMCR without external skin incision. Photographs were reviewed to objectively and subjectively compare the results of phenylephrine testing to postoperative appearance. Only patients who underwent successful MMCR were included in the study. The authors defined successful MMCR as having a resulting marginal reflex distance within 1 mm of that predicted by phenylephrine testing. For objective analysis, the tarsal platform show was measured using computer software. For subjective analysis, 2 experienced examiners were asked to grade the correlation in appearance on a scale of 1-5 (1 being poor correlation and 5 being excellent correlation). RESULTS: The mean tarsal platform show in the phenylephrine test photographs and the postoperative photographs was 3.8 and 3.63 mm, respectively (mean = 0.17; standard deviation = 0.71). The difference between the means was not statistically significant (p > 0.05). The mean difference in tarsal platform show between phenylephrine testing and postoperative was 0.17 mm (standard deviation = 0.71). The difference was not statistically significant (t[51] = 0.09; p > 0.05; 2 tailed). The mean subjective correlation score comparing phenylephrine testing photographs to postoperative photographs was 4.4 out of possible 5. CONCLUSIONS: Phenylephrine testing exhibits good predictability with regard to eyelid appearance after successful MMCR without external skin incision and, therefore, may assist the surgeon when trying to decide if blepharoplasty or eyelid crease formation is necessary at the time of MMCR.

Conjunctivodacryocystorhinostomy with Jones tube: a history and update.

PURPOSE OF REVIEW: Current opinions and trends in the management of upper lacrimal obstruction include design variations on the original Lester Jones tube and updated awareness and management of the problems associated with the tubes. This article includes a brief review of the fascinating history of the development of the Jones tube, which sets the perspective for the current scientific dialog. RECENT FINDINGS: First, many design modifications have been proposed to reduce the risk of tube migration and extrusion, with no consensus on the best tube. Second, the issue of retrograde airflow through the Jones tube with the use of continuous positive airway pressure is an increasingly common and challenging problem. Third, bacterial biofilms on the surface of the Jones tube can play a role in recalcitrant infections. Jones tubes can be cleaned or replaced in the office setting with topical anesthesia. SUMMARY: Conjunctivodacryocystorhinostomy (CDCR) with placement of a Jones tube remains the gold standard for management of upper lacrimal obstruction. This article provides an updated perspective on issues with extrusion or migration of the tube, bothersome retrograde airflow with the use of a continuous positive airway pressure device, and management of crusting and possible infectious biofilms on the tube.

Morgellons Disease Presenting As an Eyelid Lesion.

Morgellons disease is characterized by complaints of uncomfortable skin sensations and fibers emanating from nonhealing skin lesions. Morgellons disease is well-known in the dermatology and psychiatry literature, where it is typically considered a subtype of delusional parasitosis, but it has not yet been described in the ophthalmology literature. A patient with self-reported Morgellons disease is presented, who was referred for evaluation of left lower eyelid ectropion. She reported that her skin was infested with fibers that were "trying to get down into the eyelid." On examination, she had ectropion of the left lower eyelid, broken cilia, and an ulcerated left upper eyelid lesion concerning for carcinoma. Biopsy of the lesion was consistent with excoriation. Treatment of her ectropion was deferred out of concern for wound dehiscence, given the patient's aggressive excoriation behavior. This case is presented to make the ophthalmologist aware of this disorder and to highlight the appropriate clinical management.

Orbital pseudotumor can be a localized form of granulomatosis with polyangiitis as revealed by gene expression profiling.

Biopsies and ANCA testing for limited forms of granulomatosis with polyangiitis (GPA) are frequently non-diagnostic. We characterized gene expression in GPA and other causes of orbital inflammation. We tested the hypothesis that a sub-set of patients with non-specific orbital inflammation (NSOI, also known as pseudotumor) mimics a limited form of GPA. Formalin-fixed, paraffin-embedded orbital biopsies were obtained from controls (n=20) and patients with GPA (n=6), NSOI (n=25), sarcoidosis (n=7), or thyroid eye disease (TED) (n=20) and were divided into discovery and validation sets. Transcripts in the tissues were quantified using Affymetrix U133 Plus 2.0 microarrays. Distinct gene expression profiles for controls and subjects with GPA, TED, or sarcoidosis were evident by principal coordinate analyses. Compared with healthy controls, 285 probe sets had elevated signals in subjects with GPA and 1472 were decreased (>1.5-fold difference, false discovery rate adjusted p<0.05). The immunoglobulin family of genes had the most dramatic increase in expression. Although gene expression in GPA could be readily distinguished from gene expression in TED, sarcoidosis, or controls, a comparison of gene expression in GPA versus NSOI found no statistically significant differences. Thus, forms of orbital inflammation can be distinguished based on gene expression. NSOI/pseudotumor is heterogeneous but often may be an unrecognized, localized form of GPA.

Dermis fat graft implantation after unilateral enucleation for retinoblastoma in pediatric patients.

PURPOSE: To evaluate the efficacy of dermis fat graft (DFG) as a primary implant technique in pediatric patients requiring unilateral enucleation due to retinoblastoma. METHODS: A retrospective chart review of 14 consecutive pediatric patients who underwent dermis fat graft implantation after unilateral enucleation for retinoblastoma by 1 surgeon (E.A.S.) was performed to evaluate graft efficacy with regard to orbital volume growth and any associated morbidity. Patients who received chemotherapy or external beam radiation were excluded. Demographic information was recorded. Serial MRIs were used to measure orbital volumes to compare the surgical and contralateral orbits over time. The main outcome measure was the difference in bony orbital volume between enucleated and contralateral, uninvolved orbits. Mann-Whitney U test was used to compare orbital volume measurements between surgical and nonsurgical orbits. Correlation testing was performed to determine the effect of age, sex, and follow-up time on the orbital volume changes. RESULTS: There was no statistical difference between the MRI volume measured for surgical and nonsurgical orbits over time. This was the case at all measured time points and for all ages and genders. All patients were under the age of 4 years at the time of surgery. The median difference in orbital volumes between surgical and nonsurgical orbits was -0.095 cm (range -1.26 to 1.01 cm; quartiles -0.32 to 0.07 cm; mean ± SD, -0.144 ± 0.0522 cm; 95% confidence interval, -0.247 to -0.0419 cm). The median follow-up time from surgery date to the most recent clinical examination was 38.5 months (range, 13 to 70 months; quartiles, 28.75 to 45.5 months; mean ± standard deviation [SD], 38.43 ± 17.21 months; 95% confidence interval, 29.41 to 47.45 months). CONCLUSIONS: In pediatric patients below 4 years of age with unilateral retinoblastoma treated with enucleation and primary dermis fat graft implantation, there was no statistically significant difference in bony orbital volume between the surgical and nonsurgical orbits during the follow-up period.

IS5 element integration, a novel mechanism for rapid in vivo emergence of tigecycline nonsusceptibility in Klebsiella pneumoniae.

Tigecycline nonsusceptibility is concerning because tigecycline is increasingly relied upon to treat carbapenem- or colistin-resistant organisms. In Enterobacteriaceae, tigecycline nonsusceptibility is mediated by the AcrAB-TolC efflux pump, among others, and pump activity is often a downstream effect of mutations in their transcriptional regulators, cognate repressor genes, or noncoding regions, as demonstrated in Enterobacteriaceae and Acinetobacter isolates. Here, we report the emergence of tigecycline nonsusceptibility in a longitudinal series of multidrug-resistant (MDR) and extensively drug-resistant (XDR) Klebsiella pneumoniae isolates collected during tigecycline therapy and the elucidation of its resistance mechanisms. Clinical isolates were recovered prior to and during tigecycline therapy of a 2.5-month-old Honduran neonate. Antimicrobial susceptibility tests to tigecycline determined that the MIC increased from 1 to 4 µg/ml prior to the completion of tigecycline therapy. Unlike other studies, we did not find increased expression of ramA, ramR, oqxA, acrB, marA, or rarA genes by reverse transcription-quantitative PCR (qRT-PCR). Whole-genome sequencing revealed an IS5 insertion element in nonsusceptible isolates 85 bp upstream of a putative efflux pump operon, here named kpgABC, previously unknown to be involved in resistance. Introduction of the kpgABC genes in a non-kpgABC background increased the MIC of tigecycline 4-fold and is independent of a functional AcrAB-TolC pump. This is the first report to propose a function for kpgABC and identify an insertion element whose presence correlated with the in vivo development of tigecycline nonsusceptibility in K. pneumoniae.

Idiopathic lymphoplasmacellular mucositis-dermatitis of the eyelid.

Idiopathic lymphoplasmacellular mucositis-dermatitis is a rare mucosal or cutaneous disorder characterized clinically by papules or plaques with variable erosion and microscopically by dense dermal inflammatory cell infiltrates with numerous plasma cells. It has been described in the oral and upper aerodigestive tracts, male and female genitalia, and other mucosal surfaces. In this article, the authors describe a case of idiopathic lymphoplasmacellular mucositis-dermatitis occurring in the skin of the eyelid that was removed by excisional biopsy and has not recurred in the 19-month follow-up period.

Tattoo granuloma of the eyelid mimicking carcinoma.

A 68-year-old woman was referred to the Oculofacial Plastic and Reconstructive Surgery service for evaluation of a left upper eyelid lesion that was worrisome for carcinoma. The mass measured 8 × 8 mm; it was well-circumscribed, pink, and firm with distortion of the eyelid margin, central ulceration, and loss of the lashes. The patient denied previous surgery or trauma in this area, but she had a history of blepharopigmentation (tattoo eyeliner) of all 4 eyelids approximately 7 years prior. Incisional biopsy revealed inflammatory changes consistent with a localized reaction to the tattoo pigment granules. Local kenalog injection was attempted with improvement of the overall appearance but with persistent deformity including irregularity of the margin and loss of lashes. The persistent abnormal appearance was worrisome for an underlying carcinoma missed on the initial incisional biopsy and prompted a full-thickness wedge resection and reconstruction of the abnormal area. The results of biopsy of the excised tissue confirmed absence of malignant neoplasm and showed changes consistent with tattoo granuloma. Tattoo granuloma of the eyelid should be considered in the differential diagnosis of eyelid lesions worrisome for carcinoma in patients with a history of blepharopigmentation.

Orbital decompression to alleviate intermittent globe subluxation due to massive optic nerve sheath enlargement from chronic hydrocephalus.

A 59-year-old man with a history of chronic hydrocephalus and lifelong poor vision was referred to the oculoplastic surgery service for the management of symptomatic proptosis and intermittent globe subluxation of his OD. Imaging studies of his orbits revealed massively enlarged and calcified optic nerve sheaths. Neurosurgical consultation recommended against violation of the cerebrospinal fluid space given the chronic compensated hydrocephalus. Three-wall bony orbital decompression was therefore performed without complication and resulted in improved symptomatic and cosmetic outcomes.

Preoperative evaluation for periorbital surgery.

An effective preoperative evaluation is critical to the success of aesthetic surgery for the periorbital region. This review emphasizes important history questions and examination techniques, including advice for the nonophthalmologist surgeon, to help avoid ocular complications. Aesthetic surgery of the periocular area is a rewarding endeavor for both the patient and surgeon. Proper preoperative evaluation helps to avoid some of the pitfalls of operating in this delicate area and increases the likelihood of a positive outcome.

Enrichment of IGF-1R and PPARγ signalling pathways in orbital inflammatory diseases: steps toward understanding pathogenesis.

BACKGROUND: Orbital inflammatory disease (OID) encompasses a wide range of pathology including thyroid-associated orbitopathy (TAO), granulomatosis with polyangiitis (GPA), sarcoidosis and non-specific orbital inflammation (NSOI), accounting for up to 6% of orbital diseases. Understanding the underlying pathophysiology of OID can improve diagnosis and help target therapy. AIMS: To test the hypothesis that shared signalling pathways are activated in different forms of OID. METHODS: In this secondary analysis, pathway analysis was performed on the previously reported differentially expressed genes from orbital adipose tissue using patients with OID and healthy controls who were characterised by microarray. For the original publications, tissue specimens were collected from oculoplastic surgeons at 10 international centres representing four countries (USA, Canada, Australia and Saudi Arabia). Diagnoses were independently confirmed by two masked ocular pathologists (DJW, HEG). Gene expression profiling analysis was performed at the Oregon Health & Science University. Eighty-three participants were included: 25 with TAO, 6 with orbital GPA, 7 with orbital sarcoidosis, 25 with NSOI and 20 healthy controls. RESULTS: Among the 83 subjects (mean (SD) age, 52.8 (18.3) years; 70% (n=58) female), those with OID demonstrated perturbation of the downstream gene expressions of the IGF-1R (MAPK/RAS/RAF/MEK/ERK and PI3K/Akt/mTOR pathways), peroxisome proliferator-activated receptor-γ (PPARγ), adipocytokine and AMPK signalling pathways compared with healthy controls. Specifically, GPA samples differed from controls in gene expression within the insulin-like growth factor-1 receptor (IGF-1R, PI3K-Akt (p=0.001), RAS (p=0.005)), PPARγ (p=0.002), adipocytokine (p=0.004) or AMPK (p=<0.001) pathways. TAO, sarcoidosis and NSOI samples were also found to have statistically significant differential gene expression in these pathways. CONCLUSIONS: Although OID includes a heterogenous group of pathologies, TAO, GPA, sarcoidosis and NSOI share enrichment of common gene signalling pathways, namely IGF-1R, PPARγ, adipocytokine and AMPK. Pathway analyses of gene expression suggest that other forms of orbital inflammation in addition to TAO may benefit from blockade of IGF-1R signalling pathways.

Non-specific orbital inflammation: Current understanding and unmet needs.

Non-specific orbital inflammation (NSOI) is a noninfectious inflammatory condition of the orbit. Although it is generally considered the most common diagnosis derived from an orbital biopsy, it is a diagnosis of exclusion, meaning that the diagnosis requires exclusion of a systemic process or another identifiable etiology of orbital inflammation. The clinical diagnosis of NSOI is ill-defined, but it is typically characterized by acute orbital signs and symptoms, including pain, proptosis, periorbital edema, chemosis, diplopia, and less commonly visual disturbance. NSOI poses a diagnostic and therapeutic challenge: The clinical presentations and histological findings are heterogeneous, and there are no specific diagnostic criteria or treatment guidelines. The etiology and pathogenesis of NSOI are poorly understood. Here we recapitulate our current clinical understanding of NSOI, with an emphasis on the most recent findings on clinical characteristics, imaging findings, and treatment outcomes. Furthermore, gene expression profiling of NSOI and its implications are presented and discussed.

Radiologic imaging shows variable accuracy in diagnosing orbital inflammatory disease and assessing its activity.

Radiologic orbital imaging provides important information in the diagnosis and management of orbital inflammation. However, the diagnostic value of orbital imaging is not well elucidated. This study aimed to investigate the diagnostic accuracy of orbital imaging to diagnose orbital inflammatory diseases and its ability to detect active inflammation. We collected 75 scans of 52 patients (49 computed tomography (CT) scans; 26 magnetic resonance (MR) imaging scans). Clinical diagnoses included thyroid eye disease (TED) (41 scans, 31 patients), non-specific orbital inflammation (NSOI) (22 scans, 14 patients), sarcoidosis (4 scans, 3 patients), IgG4-related ophthalmic disease (IgG4-ROD) (5 scans, 3 patients), and granulomatosis with polyangiitis (GPA) (3 scans, 1 patient). Two experienced neuroradiologists interpreted the scans, offered a most likely diagnosis, and assessed the activity of inflammation, blinded to clinical findings. The accuracy rate of radiological diagnosis compared to each clinical diagnosis was evaluated. Sensitivity and specificity in detecting active inflammation were analyzed for TED and NSOI. The accuracy rate of radiologic diagnosis was 80.0% for IgG4-ROD, 77.3% for NSOI, and 73.2% for TED. Orbital imaging could not diagnose sarcoidosis. Orbital CT had a sensitivity of 50.0% and a specificity of 75.0% to predict active TED using clinical assessment as the gold standard. The sensitivity/specificity of orbital MR was 83.3/16.7% for the detection of active NSOI. In conclusion, orbital imaging is accurate for the diagnosis of IgG4, NSOI, and TED. Further studies with a large number of cases are needed to confirm this finding, especially with regard to uncommon diseases. Orbital CT showed moderate sensitivity and good specificity for identifying active TED.

An Update on Endocrine Mucin-producing Sweat Gland Carcinoma: Clinicopathologic Study of 63 Cases and Comparative Analysis.

Endocrine mucin-producing sweat gland carcinoma (EMPSGC) is a rare, low-grade adnexal neoplasm with predilection for the periorbital skin of older women. Histologically and immunophenotypically, EMPSGC is analogous to another neoplasm with neuroendocrine differentiation, solid papillary carcinoma of the breast. Both lesions are spatially associated with neuroendocrine mucinous adenocarcinomas of the skin and breast, respectively. EMPSGC is ostensibly a precursor of neuroendocrine-type mucinous sweat gland adenocarcinoma (MSC), a lesion of uncertain prognosis. Non-neuroendocrine MSC has been deemed locally aggressive with metastatic potential, and previous works speculated that EMPSGC-associated (neuroendocrine-type) MSC had similar recurrence and metastatic potential with implications for patient follow-up. Only 96 cases of EMPSGC have been reported (12 cases in the largest case series). Herein, we present 63 cases diagnosed as "EMPSGC" in comparison with aggregated results from known published EMPSGC cases. We aim to clarify the clinicopathologic features and prognostic significance of the neuroendocrine differentiation of EMPSGC and its associated adenocarcinoma and to determine the nosological relevance of EMPSGC association in the spectrum of MSC histopathogenesis. Results established an overall female predominance (66.7%) and average presenting age of 64 years. EMPSGC lesions were associated with adjacent MSC in 33.3% of cases. The recurrence rate for neuroendocrine-type MSC was ~21%, less than the reported 30% for non-neuroendocrine MSC. There were no cases of metastasis. EMPSGC and neuroendocrine-type MSC are distinct entities with more indolent behavior than previously reported, supporting a favorable prognosis for patients.

Conjunctivodacryocystorhinostomy with the frosted jones pyrex tube.

PURPOSE: To report the results of conjunctivodacryocystorhinostomy with primary placement of a frosted Jones Pyrex tube in the treatment of epiphora from upper lacrimal dysfunction. METHODS: A retrospective chart review was performed for patients who had undergone conjunctivodacryocystorhinostomy with primary placement of a frosted Jones Pyrex tube performed by a single surgeon (R.A.D.). All patients with at least 6 months of follow-up were included in the study. Efficacy was judged by patient report of resolution of tearing and charts were reviewed for complications. RESULTS: Five conjunctivodacryocystorhinostomy procedures were performed with primary placement of a frosted Jones Pyrex tube. Four of the surgeries were performed for a diagnosis of flaccid canaliculi and one for a congenital upper lacrimal obstruction that had been unsuccessfully treated with previous surgery at another institution. Three of the surgeries were performed with an endoscopic approach and 2 were performed with an external approach. Follow-up ranged from 29 to 34 weeks (mean, 31.2 weeks). All patients reported complete resolution of tearing and no complications were noted, including no evidence of tube migration or extrusion. CONCLUSIONS: Primary placement of frosted Jones Pyrex tubes in patients undergoing conjunctivodacryocystorhinostomy seems to retain the efficacy of a standard Jones Pyrex tube while reducing the likelihood of tube extrusion, which is the main complication of this surgery.

Comparison of injection pain of articaine and lidocaine in eyelid surgery.

PURPOSE: To compare the pain induced by tissue infiltration of lidocaine 2% with epinephrine 1:100,000 versus articaine 4% with epinephrine 1:100,000 for eyelid surgery. METHODS: Thirty patients undergoing bilateral eyelid surgery were enrolled in a prospective, randomized, double-masked study. Each subject received injections of lidocaine 2% with epinephrine 1:100,000 (Xylocaine) on one side and articaine 4% with epinephrine 1:100,000 (Septocaine) on the other for surgical anesthesia. The patients rated the pain of infiltration using a 100-mm visual analogue scale immediately after receiving each injection. The pain scores were compared using the paired t test. RESULTS: Twenty-two of the 30 patients (73.3%) rated the articaine injection as less painful than the lidocaine injection. The mean pain score for lidocaine was 42.60 +/- 24.74 and the pain score for articaine was 31.85 +/- 20.28 (p = 0.011). CONCLUSIONS: In this study, infiltration of articaine was less painful than lidocaine for eyelid surgery, making articaine an attractive alternative for local anesthesia.

The management of large-angle esotropia in Graves ophthalmopathy with combined medial rectus recession and lateral rectus resection.

PURPOSE: To describe surgical management and outcomes for large-angle esotropia of ≥50Δ secondary to Graves ophthalmopathy using combined initial nonadjustable medial rectus recessions and lateral rectus resections. METHODS: The medical records of consecutive patients undergoing strabismus surgery for large-angle esotropia secondary to Graves ophthalmopathy from 1995 to 2012 by a single surgeon at each of two institutions was performed. Patient characteristics, surgical technique, and pre- and postoperative measurements of ocular alignment were analyzed. A modified Gorman diplopia scale was used to assess outcome. RESULTS: Of 38 patients, 36 had bilateral nonadjustable medial rectus recessions and lateral rectus resections as initial treatment for esotropia, and 6 patients underwent simultaneous vertical muscle surgery. Mean preoperative horizontal deviation was 60Δ and mean preoperative vertical deviation was 10Δ. Of the 38 patients, 19 (50%) reached the primary outcome, including 5 of 6 (85%) who had no preoperative vertical strabismus. The indications for reoperation were vertical strabismus in 13 of 21 patients (62%), residual esotropia in 7 of 21 (33%), and consecutive exotropia in 1 of 21 (5%). With a median follow-up of 13.2 months after first surgery, 32 of 38 patients (84%) reached the secondary outcome. CONCLUSIONS: Combining nonadjustable medial rectus recessions with lateral rectus resections can be a beneficial primary treatment for large-angle esotropia in patients with Graves ophthalmopathy, especially in those patients with small or no associated vertical strabismus.
