RESUMEN
PURPOSE: To review the efficacy and safety of oral vismodegib (Erivedge; Genentech) in the management of locally advanced orbital and periorbital basal cell carcinoma (BCC). METHODS: A literature search was conducted last in September 2023 in the PubMed database for English language original research that evaluated the effect of oral vismodegib on orbital and periorbital BCC. Sixty articles were identified and 16 met the inclusion criteria. RESULTS: Most studies demonstrated high response rates, with up to 100% of patients responding to the medication in individual studies and initial complete regression occurring in up to 88% of patients. Vismodegib treatment resulted in significant reductions in tumor volume, resulting in globe preservation for most patients. However, in 12% of patients, the response was partial. Recurrences also occurred with substantial frequency, even after an initial complete response. As such, up to 79.4% of patients required surgical intervention, and up to 23% of patients still required exenteration. Use of these agents resulted in reductions in tumor volume that may delay or prevent the need for exenteration in some, but not all, patients. Importantly, molecular analysis of tissue excised after vismodegib therapy revealed persistent tumor in all patients, with frequent accumulation of mutations that may confer resistance to further hedgehog inhibitor therapy. Although most adverse events were rated as level I or II, side effects were common, with up to 100% of patients in studies experiencing at least 1 event. Muscle cramps, alopecia, weight loss, fatigue, and dysgeusia were the most common adverse events, and several patients discontinued therapy because of them. Furthermore, 1 patient died of sepsis that may have resulted from the therapy. CONCLUSIONS: Although level I and II evidence are lacking, most studies indicate a benefit from the use of oral vismodegib to treat orbital and periorbital BCC tumor volume. However, patients should be cautioned about the adverse side effects of treatment and the persistence of tumor cells with mutations that may cause long-term resistance. Use of vismodegib as short-term neoadjuvant therapy may be effective in shrinking tumor volume to reduce surgical morbidity while reducing the frequency and severity of side effects.

RESUMEN
PURPOSE: To review the efficacy and safety of the use of intraoperative image guidance (IIG) in orbital and lacrimal surgery. METHODS: A literature search of the PubMed database was last conducted in November 2023 for English-language original research that assessed the use of any image guidance system in orbital and lacrimal surgery that included at least 5 patients. The search identified 524 articles; 94 were selected for full-text analysis by the panel. A total of 32 studies met inclusion criteria. The panel methodologist assigned a level II rating to 2 studies and a level III rating to 30 studies. No study met the criteria for level I evidence. RESULTS: Procedures reported on were as follows: fracture repair (n = 14), neoplasm and infiltrate biopsy or excision (n = 6), orbital decompression for Graves ophthalmopathy (n = 3), dacryocystorhinostomy (n = 1), and mixed etiology and procedures (n = 8). Four studies used more than one IIG system. One study that met level II evidence criteria compared the outcomes of orbital fracture repair with IIG (n = 29) and without IIG (n = 29). Borderline better outcomes were reported in the IIG group: 2% versus 10% with diplopia (P = 0.039) and 3% versus 10% with enophthalmos (P = 0.065). The other level II study compared the repair of fractures with navigation (n = 20) and without (n = 20). The group in which navigation was used had a measured mean volume reduction of 3.82 cm3 compared with 3.33 cm3 (P = 0.02), and there was a greater measured reduction in enophthalmos in the navigation group of 0.72 mm (P = 0.001). Although the remaining 30 assessed articles failed to meet level II criteria, all alleged a benefit from IIG. No complications were reported. CONCLUSIONS: A small number of comparative studies suggest that there are improved outcomes when IIG is used in orbital fracture repair, but each study suffers from various limitations. No high-quality comparative studies exist for the management of lacrimal surgery, neoplastic disease, or decompression. Complications attributable to the use of IIG have not been identified, and IIG has not been analyzed for cost savings.

RESUMEN
PURPOSE: To review the literature on the adjuvant use of mitomycin C (MMC) during dacryocystorhinostomy (DCR) in adults with primary nasolacrimal duct obstructions (NLDOs) to determine the efficacy in improving functional and anatomic outcomes with an acceptable level of risk. METHODS: A literature search conducted in November 2020 and updated in November 2022 yielded 137 articles. Twenty-four articles met the inclusion criteria and were rated for level of evidence by the panel methodologist. Inclusion criteria required controlled studies on the effect of MMC on outcomes of external, endoscopic endonasal, or diode laser-assisted transcanalicular DCR in adults with primary acquired nasolacrimal obstruction with 6 months minimum follow-up and at least 10 participants. RESULTS: Six of the 24 articles were rated level I evidence, 15 level II , and 3 level III. In primary external DCR, MMC significantly improved functional outcomes in 3 of 9 series. In primary endoscopic endonasal DCR, MMC significantly improved functional outcomes in 1 of 9 series. In revision endoscopic endonasal DCR, MMC significantly improved functional success in 1 of 3 series. The use of MMC did not improve outcomes statistically in any diode laser-assisted transcanalicular DCR studies. Concentrations of MMC ranged from 0.05 to 1 mg/ml, with 0.2 mg/ml used most frequently in 12 series, with duration of application ranging from 2 to 30 minutes. Ostium size was significantly larger in MMC groups than in control groups at 6 months after surgery in 4 of 5 reporting studies. However, these larger ostia did not confer higher functional success rates. Reporting of adverse events related to MMC were rare, with delayed cutaneous wound healing reported in 1 of 750 patients. CONCLUSIONS: Intraoperative use of MMC in external and endoscopic endonasal DCR has been shown to improve functional and anatomic outcomes compared with controls in some series, but there is no agreement on the recommended concentration or application time for MMC in DCR. The data support that MMC use can result in a larger ostium size, decreased granulation tissue formation, and a decreased number of postoperative nasal debridements compared with controls, but this does not translate into improved functional success.

RESUMEN
PURPOSE: To review the literature to determine the efficacy and safety of thermal pulsation technologies in improving signs or symptoms of meibomian gland dysfunction (MGD) and dry eye compared with no therapy or with conventional warm compress therapy or eyelid hygiene. METHODS: A literature search was conducted in the PubMed database in June 2022 and again in March 2023 to identify all studies in the English language on the use of thermal pulsation to treat MGD or dry eye. The search yielded 59 citations, and 11 articles met all of the inclusion criteria. The panel methodologist then assigned a level of evidence rating for each study; 8 studies were rated level I evidence and 3 studies were rated level II evidence. RESULTS: All included studies evaluated a single 12-minute session using the LipiFlow automated thermal pulsation system (TearScience, Inc, or Johnson & Johnson). Improvements were detected in subjective and objective metrics of MGD or dry eye in patients within 1 to 12 months of thermal pulsation treatment compared with nontreatment. Most of the studies (9/11) reported greater efficacy with thermal pulsation than with standard warm compress therapy and eyelid hygiene. Four of these studies showed relevant industry conflicts of interest. Two of the 4 level I studies without direct industry participation concluded that thermal pulsation treatment was not significantly different from conventional hygiene or warm compress therapy control treatments (in symptoms in one of the studies and in objective findings in the second study). No serious adverse events were reported in any of the 11 studies. CONCLUSIONS: According to the current literature, a single thermal pulsation session may improve subjective or objective parameters of MGD and dry eye safely. However, industry support and participation were present in 4 of the 8 level I studies. The durability beyond several months and cost efficacy remain uncertain. Because the inclusion parameters of this assessment captured only the LipiFlow system, the conclusions are limited to that product. High-quality independent studies are needed to assess the long-term benefits of this intervention.

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.

BACKGROUND: In this study, we seek to answer the question: Does blepharoplasty for dermatochalasis alter visual performance? OBJECTIVES: We seek to determine the impact of blepharoplasty on visual performance (refraction, contrast sensitivity, and visual field) in patients with dermatochalasis. METHODS: A total of 146 eyelids of 74 patients, 48 (64.9%) females and 26 (35.1%) males ranging from 40 to 68 years old, with dermatochalasis were analyzed prospectively. Refraction, contrast sensitivity, visual acuity, higher-order aberrations (HOAs), and mean deviation index (MDI) in the Humphrey visual field were evaluated and recorded before and at 2, 4, and 6 months after upper eyelid blepharoplasty. RESULTS: At the latest follow-up, uncorrected and corrected distance visual acuity showed no significant differences (P > .05). Patients' contrast sensitivity increased significantly at all spatial frequencies under both conditions (P < .05) except at 12 cycles per degree in the photopic condition (P = .947). Mean astigmatism significantly decreased from -1.17 ± 0.83 to -0.89 ± 0.66 postoperatively (P ≤ .001). Total HOAs decreased significantly from 0.59 ± 0.13 µm to 0.51 ± 0.09 µm (P < .01) after surgery. The root mean square of the spherical aberration (P < .01), vertical trefoil (P = .018), horizontal trefoil (P < .01), horizontal coma (P < .001), and vertical coma (P < .01) decreased significantly. The MDI of the Humphrey visual field increased significantly postoperatively at all times compared with preoperatively (P < .05). The Blepharoplasty Outcomes Evaluation questionnaire showed significant favorable satisfaction with visual quality indexes (P < .001). CONCLUSIONS: Upper lid blepharoplasty, in addition to its aesthetic effect, is an effective intervention to promote visual function and quality of life.

Age-related changes in the lower eyelid are noticed by patients as bags or circles under the eye, a tired look, and a flattened face. Lower eyelid blepharoplasty, in which the excess skin and/or orbital fat is excised and repositioned, is mainly performed for aesthetic reasons rather than the correction of functional abnormalities. Favorable outcomes for the combination of these approaches have been reported, but the most suitable surgical technique is still debated. This systematic narrative review deals with the indications, preoperative considerations, operative techniques, and complications of several different surgical approaches to lower eyelid blepharoplasty.

PURPOSE: To review the current literature on the safety and efficacy of orbital radiation for the management of thyroid eye disease (TED). METHODS: A literature search was conducted last in February 2021 of the PubMed database to identify all articles published in the English language on original research that assessed the effect of orbital radiation on TED. The search identified 55 articles, and 18 met the inclusion criteria for this assessment. A panel methodologist then assigned a level of evidence rating for each study, and all of them were rated level III. RESULTS: Two large retrospective studies demonstrated the efficacy of radiation treatment, with or without corticosteroid use, in preventing or treating compressive optic neuropathy (CON). Three studies highlighted the role of orbital radiation therapy (RT) to facilitate the tapering of corticosteroids. Several other studies showed a possible role for RT to improve diplopia and soft tissue signs. CONCLUSIONS: Although no level I or level II evidence exists, the best available evidence suggests that orbital radiation, used with or without corticosteroids, is efficacious in preventing CON, improving motility restriction, and decreasing clinical activity in TED. Orbital radiation also may facilitate a corticosteroid taper. Together, these studies show that RT seems to modify the active phase of TED. Short-term risks of orbital radiation are minor, but long-term outcome data are lacking.

PURPOSE: To review the published literature to determine the efficacy and safety of homeopathic agents or vitamins in reducing ecchymosis after oculofacial surgery or laser surgery. METHODS: A literature search was conducted in the PubMed database initially in December 2019 and updated in March 2020 to identify all studies in the English language literature on the use of homeopathic agents or vitamins in oculofacial procedures, including laser surgery. The search yielded 124 citations, and 11 articles met all inclusion criteria for this assessment. A panel methodologist then assigned a level of evidence rating for each study. Eleven studies met inclusion criteria; 9 were rated level I, and 2 were rated level III. RESULTS: The agents studied in the articles identified included oral or topical Arnica montana (AM), oral Melilotus extract, topical vitamin K oxide, and topical AM combined with Rhododendron tomentosum. Metrics to describe ecchymosis varied. In 7 controlled studies, perioperative AM provided no or negligible benefit versus placebo. In 2 studies, vitamin K cream was equivalent to placebo. One study of oral Melilotus extract had less ecchymosis compared with controls in paranasal and eyelid ecchymosis at postoperative day (POD) 7, but not at PODs 1 and 4. A lone cohort study of combined topical AM and R. tomentosum lacked objective metrics and adequate controls. No serious side effects from administration of homeopathic agents or vitamins were identified. CONCLUSIONS: The current literature does not support the use of AM, vitamin K oxide, R. tomentosum, or Melilotus extract for reducing ecchymosis after oculofacial surgery or pulsed dye laser surgery.

PURPOSE: To review the literature on the efficacy and safety of medical and surgical interventions for indirect traumatic optic neuropathy (TON), defined as injury to the nerve that occurs distal to the optic nerve head. METHODS: A literature search was conducted on October 22, 2019, and updated on April 8, 2020, in the PubMed database for English language original research that assessed the effect of various interventions for indirect TON. One hundred seventy-two articles were identified; 41 met the inclusion criteria outlined for assessment and were selected for full-text review and abstraction. On full-text review, a total of 32 studies met all of the study criteria and were included in the analysis. RESULTS: No study met criteria for level I evidence. Seven studies (1 level II study and 6 level III studies) explored corticosteroid therapy that did not have uniformly better outcomes than observation. Twenty studies (3 level II studies and 17 level III studies) assessed optic canal decompression and the use of corticosteroids. Although visual improvement was noted after decompression, studies that directly compared surgery with medical therapy did not report uniformly improved outcomes after decompression. Four studies (1 level II study and 3 level III studies) evaluated the use of erythropoietin. Although initial studies demonstrated benefit, a direct comparison of its use with observation and corticosteroids failed to confirm the usefulness of this medication. One study (level II) documented visual improvement with levodopa plus carbidopa. Complication rates were variable with all of these interventions. Pharmacologic interventions generally were associated with few complications, whereas optical canal decompression carried risks of serious side effects, including hemorrhages and cerebrospinal fluid leakage. CONCLUSIONS: Despite reports of visual improvement with corticosteroids, optic canal decompression, and medical therapy for indirect TON, the weight of published evidence does not demonstrate a consistent benefit for any of these interventions. In summary, no consensus exists from studies published to date on a preferred treatment for TON. Treatment strategies should be customized for each individual patient. More definitive treatment trials will be needed to identify optimal treatment strategies for indirect TON.

PURPOSE: To review the literature on the efficacy of intense pulsed light (IPL) on the eyelids in the management of meibomian gland disease (MGD) and meibomian gland-related ocular surface disease. METHODS: A literature search was last conducted on May 15, 2019, in the PubMed and Cochrane Library databases for English-language original research that assessed the effect of IPL on MGD in adult patients. Thirty-three articles were identified, and 12 studies were determined to be relevant to the criteria outlined for assessment. The panel methodologist (V.K.A.) assigned a level of evidence rating to each study; 4 studies were rated level II, and 8 studies were rated level III. Five studies had potential conflicts of interest and design limitations that affected interpretation of results. RESULTS: All studies documented improvement in clinically meaningful metrics, including tear breakup time (TBUT), corneal staining and eyelid margin measurements, meibum quality, meibomian gland expressability, ocular surface disease index (OSDI), and standard patient evaluation of eye dryness (SPEED) questionnaire scores. Side effects were relatively uncommon but included discomfort, cutaneous erythema, blistering, eyelash loss, and floaters; these were uniformly self-limited. CONCLUSIONS: Although methodological limitations and potential conflicts of interest in some studies raised concern, the existing body of literature demonstrates improvements in the signs and symptoms of MGD after IPL therapy.

PURPOSE: To review the literature on the efficacy and safety of bioengineered acellular dermal matrix (BADM) grafts for lower eyelid retraction repair. METHODS: A literature search was conducted in the PubMed database initially in January 2018 and updated in July 2019 to identify all studies in the English language literature on the use of BADM grafts in eyelid reconstruction. The searches yielded 193 citations, and 15 of the 34 articles selected for full review met all inclusion criteria for this assessment. A panel methodologist then assigned a level of evidence rating for each study. Two of the 15 studies included were rated level II and 13 were rated level III. RESULTS: The definition of success varied, but lower eyelid position improvement using lower lid margin-to-pupillary reflex distance was the most common outcome measure. Other end points were the amount of lagophthalmos, cosmesis, exposure, reoperation, or complications, as well as prosthesis retention in anophthalmic socket cases. The surgeon-reported success rate of these outcomes ranged from 75% to 100%. Minor complications included cyst formation, infection, chemosis, pyogenic granuloma, and corneal abrasion. No serious complications such as blindness, anaphylactic reaction, or terminal disease transmission occurred. Of the 526 implants included for assessment in these disparate studies, 27 cases (5%) required reoperation. CONCLUSIONS: No level I evidence was available, and the existing level II and level III studies have variable primary end points, study design limitations, and only short-term follow-up data. The current literature suggests that BADM grafts represent an implantation option for lower eyelid retraction repair. Short-term results are favorable, and the materials used may fill an important gap in care for patients for whom no acceptable alternatives exist, but long-term safety and efficacy remain unknown.

PURPOSE: To determine the efficacy and safety of sentinel lymph node biopsy (SLNB) in the management of eyelid and conjunctival malignancy. METHODS: A literature search was performed in August 2019 and January 2020 for articles published in English in the PubMed and Cochrane Library databases. This search yielded 151 articles that were reviewed for relevancy, of which 27 were deemed to have met the inclusion criteria for this assessment. The data from these articles were abstracted and the articles were rated for strength of evidence by the panel methodologist. RESULTS: All 27 studies were rated level III, and a total of 197 SLNBs were reported. Diagnoses included conjunctival and eyelid cutaneous melanoma (85 and 42 patients, respectively), sebaceous gland carcinoma (35 patients), squamous cell carcinoma (26 patients), Merkel cell carcinoma (6 patients), pigmented epithelioid melanocytoid tumor (1 patient), mucoepidermoid carcinoma (1 patient), and signet ring carcinoma (1 patient). Tracer was found in regional lymph nodes in 100% of patients in 21 of 27 articles and in 191 of 197 patients overall. The number of lymph nodes removed ranged from 1 to 16, with most ranging from 1 to 5. Tumor-positive lymph nodes were found in 33 of 197 patients (16.8%), prompting recommendations for adjuvant treatments. Survival data were reported for 16 of these patients, with follow-up periods ranging from 3 to 36 months (average, 12.7 months). Fourteen of 16 patients received adjuvant treatments. Nine were alive and well, 1 was alive with metastases, and 6 had died of metastatic disease (including 2 patients who declined additional treatment). False-negative SLNB results were reported in 5 articles involving 9 of 197 procedures (4.6%). Complications were documented in 7 of 27 articles and included transient facial nerve weakness, persistent blue dye staining of the conjunctiva, neck hematoma, and suture abscess. CONCLUSIONS: Sentinel lymph node biopsy is a promising procedure in patients with eyelid and conjunctival malignancy, and it is useful in identifying sentinel lymph nodes. However, at present, insufficient evidence exists showing that SLNB improves patient outcomes and survival. Recognition of microscopic metastatic disease may prove beneficial in staging and guiding adjuvant therapy.

PURPOSE: To determine the efficacy and complication rates of monocanalicular stents in the setting of canalicular lacerations. METHODS: A literature search was performed in May 2018 in the PubMed database to identify all English-language reports of monocanalicular stenting to address canalicular lacerations. Studies that did not include at least 10 patients with at least 3 months of follow-up evaluation after surgery were excluded. Ninety-nine articles were identified, and 15 of these met criteria for data abstraction and were included in this assessment. The panel methodologist (V.K.A.) evaluated the quality of evidence and assigned a level-of-evidence rating to each of these studies. RESULTS: All 15 studies were rated as level III evidence. Anatomic and functional success rates after surgery ranged from 68% to 100% and 79% to 100%, respectively. Stents were generally well tolerated, although extrusion rates varied from 0% to 29%. CONCLUSIONS: Only level III evidence was available, and studies were not powered to detect differences between groups for rare complications or failure. Monocanalicular stents seem to be efficacious and well tolerated in the management of canalicular lacerations. Potential complications include extrusion (most commonly), tube displacement, granuloma, ectropion, slit punctum, fistula, and infection. Further comparative studies would help to identify the optimal time for device removal and to directly compare monocanalicular with bicanalicular stents.

BACKGROUND: Dacryocystorhinostomy (DCR) can be performed via an external or endoscopic approach. The use of ultrasonic or piezosurgery has been well described for endoscopic DCRs but is lacking for external DCRs. This study presents a case series of external DCRs performed using piezosurgery evaluating results and complications. METHODS: Prospective, consecutive case series of patients undergoing primary external DCR for lacrimal drainage insufficiency. A standard external DCR technique was used using 1 of 2 piezosurgery systems for all bone incision. All patients received silicone intubation to the lacrimal system. Surgical outcome was measured in terms of patient-reported epiphora as follows: 1) complete resolution, 2) improvement >50%, 3) improvement <50%, and 4) No improvement. Intra and postoperative complications were also recorded. RESULTS: Fifty-two patients, 14 male and 38 female, were included in the study, with 2 patients having bilateral surgery. The average age of the patients was 55.8 years. The average length of follow up was 221 days. Surgical outcomes showed 72% of patients with complete resolution of epiphora and 21% with >50% improvement. There were 4 patients (7%) who had <50% improvement. There was 1 (2%) intraoperative complication and 2 (4%) postoperative complications recorded. CONCLUSIONS: Piezourgery is a viable modality for performing external DCRs. The lack of surgical complications shows a potential for decreased soft tissues damage. The surgical success rate based on patient-reported epiphora is similar to those published for mechanical external DCRs. This modality may benefit the novice surgeon in the reduction of soft and mucosal tissue damage.

BACKGROUND: The revised 2014 American College of Cardiology (ACC)/American Heart Association valvular heart disease guidelines provide evidenced-based recommendations for the management of mitral regurgitation (MR). However, knowledge gaps related to our evolving understanding of critical MR concepts may impede their implementation. METHODS: The ACC conducted a multifaceted needs assessment to characterize gaps, practice patterns, and perceptions related to the diagnosis and treatment of MR. A key project element was a set of surveys distributed to primary care and cardiovascular physicians (cardiologists and cardiothoracic surgeons). Survey and other gap analysis findings were presented to a panel of 10 expert advisors from specialties of general cardiology, cardiac imaging, interventional cardiology, and cardiac surgeons with expertise in valvular heart disease, especially MR, and cardiovascular education. The panel was charged with assessing the relative importance and potential means of remedying identified gaps to improve care for patients with MR. RESULTS: The survey results identified several knowledge and practice gaps that may limit implementation of evidence-based recommendations for MR care. Specifically, half of primary care physicians reported uncertainty regarding timing of intervention for patients with severe primary or functional MR. Physicians in all groups reported that quantitative indices of MR severity were frequently not reported in clinical echocardiographic interpretations, and that these measurements were not consistently reviewed when provided in reports. In the treatment of MR, nearly 30% of primary care physician and general cardiologists did not know the volume of mitral valve repair surgeries by their reference cardiac surgeons and did not have a standard source to obtain this information. After review of the survey results, the expert panel summarized practice gaps into 4 thematic areas and offered proposals to address deficiencies and promote better alignment with the 2014 ACC/American Heart Association valvular disease guidelines. CONCLUSION: Important knowledge and skill gaps exist that may impede optimal care of the patient with MR. Focused educational and practice interventions should be developed to reduce these gaps.

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.

PURPOSE: To describe a surgical technique for repair of medial ectropion that simply and reliably addresses tendinous laxity and punctal eversion. METHODS: Prospective, single-blind, consecutive case study of 54 patients (79 eyes) by 3 surgeons. The subject population consisted of 33 males and 21 females, with a mean age of 81 years (SD = 9, range = 64-97). The presenting mechanisms of ectropion were as follows: cicatricial (n = 10), paralytic (n = 1), involutional (n = 62), mechanical (n = 3), and congenital (n = 3). Ectropion and punctal eversion was surgically addressed by use of a purse string suture that incorporated closure of a medial spindle incision and deep fixation to the base of the caruncle. RESULTS: The average postoperative follow-up period was 147 days (SD = 291, range 8-2,352). Sixty-four eyes had a presenting complaint of tearing (81%), with 50 eyes (78%) achieving complete resolution (p = 0.0001). Eyelid malposition was determined to be anatomically corrected in 34 of 35 eyes (97%, p = 0.0001). Four of the 79 operated eyelids had recurrence of ectropion (5%). All other reported complications were minor, resolved without sequalae. CONCLUSION: The technique demonstrated safety, efficacy, and reproducibility, regardless of ectropion mechanism. Incorporation of a purse string suture between the lower eyelid portion of the medial canthal tendon and the caruncle produces a reliable posterior-superior fixation parallel to the vectors of the posterior limb of the medial canthal tendon. This technique is equally effective as a primary correction method or when used in combination with other procedures.

PURPOSE: To assess intraoperative blood splatter to the ocular surface and adnexa during oculofacial surgery. METHODS: Four surgeons and multiple assistants at three separate locations wore a total of 331 protective eye shields during 131 surgeries. Postoperatively, a luminol blood detection system was used to identify blood splatter on the shields. In the event of positive blood splatter, the total number of blood spots was counted. Controls were used to verify the blood detection protocol. A postoperative questionnaire was given to all surgeons and assistants after each case, and they were asked whether intraoperative blood splatter was noticed. RESULTS: Blood was detected on 61% of eye shields and in a total of 80% of surgical cases. However, only 2% of blood splatters were recognized intraoperatively by the surgical participants. There was no significant difference in the splatter rate between surgeons (64%), assistants (60%), and surgical technicians (58%) (p = 0.69). Shields worn during full-thickness eyelid procedures, direct brow lifting, orbitotomy with bony window, and orbital fracture repairs were more likely to be splattered (p = 0.03), and there was a significant difference between splatter rates among different surgeons (range, 29-90%; p = 0.0004), suggesting that blood splatter rate may be both procedure dependent and surgeon dependent. CONCLUSIONS: Mucocutaneous and transconjunctival transmission of human immunodeficiency virus and viral hepatitis has been documented. These results suggest that oculofacial plastic surgeons should consider eye protection for patients with known blood-borne diseases and in cases where blood splatter is expected. This precautionary practice is supported by the high incidence (98%) of undetected, intraoperative blood splatter.

PURPOSE: The aim of this study is to investigate whether volumetric enhancement of the infraorbital rim area or, alternatively, of the deep medial cheek, results in greater improvement of tear trough deformity. METHODS: This prospective, single-blind study recruited 12 patients seeking correction of tear trough deformity. Pretreatment standardized photographs were obtained after which patients were randomized to receive hyaluronic acid gel filler augmentation of the tear trough on one side and hyaluronic acid gel augmentation of the cheek on the contralateral side. The patients were then re-examined at 3 weeks postinjection when standardized photographs were taken again. Following the photographs, filler was added to the side and location where they were not used at the original treatment, resulting in added volume in both the cheek and the tear trough. The patients returned 3 weeks later when final photographs were taken. The pre- and post-treatment images were randomized and evaluated by 3 masked observers asked to evaluate the depth of tear trough. RESULTS: There was a significant improvement in the depth of the tear trough rating after initial treatment on the side treated in the tear trough (p = 0.0001). There was not a significant change in depth of tear trough rating, however, on the side receiving cheek only treatment (p = 0.0963). There was a statistically significant change in tear trough rating after both tear trough and cheek had been treated on each side (p = 0.001). There was no statistically significant difference between sides after lid and cheek treatment had been completed on each side (p = 0.5986). Intraclass correlation between reviewers for all subjects was excellent at 0.94. Tear trough injections were more technique sensitive than cheek volume augmentation to achieve satisfactory results. There were no complications from cheek volume enhancement. Varying degrees of ecchymosis were encountered with tear trough injections. CONCLUSIONS: When the patient's primary concern is the appearance of the tear trough, and the physician is limited to treating either the tear trough or the cheek alone, it appears that treatment in the tear trough offers greater improvement in the appearance of the tear trough deformity when compared with treatment in the cheek alone.
