Corneal Manifestations in Patients with Hidradenitis Suppurativa.

PURPOSE: To report two cases of bilateral blepharokeratoconjunctivitis associated with hidradenitis suppurativa (HS). METHODS: Case report and literature review. The clinical courses of two patients with HS, including ocular presentation and medical management, are described. RESULTS: Two female patients aged 18 and 23-years-old with severe HS presented with bilateral blepharokeratoconjunctivitis. Shared slit lamp findings included bilateral corneal neovascularization and inferior corneal thinning. Systemic immunosuppression was needed in the first case, which resulted in improvement in the patient's ophthalmic and dermatological findings. CONCLUSION: We report two cases of bilateral blepharokeratoconjunctivitis in two patients with severe HS. To our knowledge, this association has not previously been described in the literature. Clinicians should be aware of this association given its potentially visually devastating manifestations and the need for early therapeutic interventions.

Incidence of Strabismus Post-Plaque Brachytherapy in Patients With Uveal Melanoma.

PURPOSE: To determine the incidence and type of strabismus in patients with uveal melanoma treated with plaque brachytherapy. DESIGN: Multicenter, retrospective incidence estimation study. METHODS: A total of 438 eyes of 438 patients with uveal melanoma treated with plaque brachytherapy between October 2011 and May 2021. Intervention was Iodine 125, and Palladium 103 plaque brachytherapy. The variables reviewed included incidence of nonresolving strabismus post-plaque brachytherapy, type of strabismus developed, extraocular muscles operated, and modality of treatment received. RESULTS: A total of 438 patients underwent plaque brachytherapy treatment for uveal melanoma. Eleven patients developed strabismus post-plaque brachytherapy (2.5%, n = 11/438). Of these patients, 5 (1.1%, n = 5/438) developed strabismus immediately postoperation. Specifically, 2 patients (0.5%, n = 2/438) developed strabismus immediately postoperation due to slipped muscles, 2 patients (0.5%, n = 2/438) due to decompensated phorias, and 1 patient (0.5%, n = 1/438) due to a fibrotic muscle. Six patients (1.4%, n = 6/438) developed late-onset sensory strabismus. A total of 355 patients (81.1%, n = 355/438) had their extraocular muscles disinserted during surgery, with the lateral rectus being the most common, accounting for 45.4% (n = 161/355), followed by the superior rectus at 26.8% (n = 95/355). Strabismus surgery was the most common treatment modality, comprising 72.7% (n = 8/11) of patients. CONCLUSIONS: The incidence of strabismus after plaque brachytherapy treatment for uveal melanoma was low and primarily classified as late-onset sensory strabismus. Previous studies may underestimate the long-term incidence of strabismus after plaque brachytherapy by focusing primarily on strabismus present immediately postoperatively.

Rapid Posterior Capsular Opacification in Two Patients Treated for Negative Dysphotopsias.

Background: Negative dysphotopsias (ND) are visual aberrations associated with in-the-bag optic intraocular lens (IOL) placement, causing arc-shaped or linear shadows. Reverse optic capture (ROC) is employed to prevent ND, yet it poses the risk of posterior capsular opacification (PCO) which usually develops within 2-5 years post-surgery due to the lens epithelial cells (LECs) proliferation and migration onto the posterior capsule. This can lead to a cloudy or hazy appearance in the visual field. Early identification of posterior capsular opacities is crucial to ensure timely intervention and minimize visual impairment. Cases Presentations: Two cases of acute and rapidly progressive PCO following cataract extraction (CE) and IOL placement using the ROC technique to prevent ND are reported at the Bascom Palmer Eye Institute. At the two-week postoperative follow-up, both patients reported a significant progressive decrease in vision in the treated eye, and severe posterior capsular opacities were observed. A diagnosis of PCO was confirmed, and successful visual rehabilitation was achieved through the performance of ND:YAG laser capsulotomy without complications. This case series represents the first reported instances of patients developing PCO within two weeks of CE and IOL placement using the ROC technique. Conclusions: This case series sheds light on the occurrence of posterior capsular opacities shortly after CE and IOL placement using the ROC technique. It highlights the importance of preoperative patient education, postoperative monitoring, and prompt management of potential complications in cataract surgery.

It Is All About the Angle: A Clinical and Optical Coherence Tomography Comparison of Corneal Ocular Surface Squamous Neoplasia and Corneal Pannus.

PURPOSE: The aim of this study was to compare clinical characteristics and high-resolution optical coherence tomography (HR-OCT) findings between corneal ocular surface squamous neoplasia (OSSN) and corneal pannus. METHODS: Retrospective study of 9 individuals, 3 with lesions histologically confirmed to be OSSN, 3 with lesions histologically confirmed to be pannus, 1 with lesions histologically confirmed to be OSSN followed by pannus, and 2 with long-standing, nonchanging lesions clinically diagnosed as pannus. All individuals presented to the Miami Veterans Affairs Medical Center eye clinic or Bascom Palmer Eye Institute between 2015 and 2023. Clinical characteristics and HR-OCT findings were evaluated and compared. RESULTS: Mean age of the population was 72.8 ± 5.1 years, 100% self-identified as male, 100% as White, and 11.1% as Hispanic. Clinically, all lesions appeared as whitish, opalescent, variably vascularized opacities extending from the limbus. None of the OSSN cases had vessels that extended to the border, whereas 4 cases of pannus (67%) had at least 1 vessel that reached the border. On HR-OCT, epithelial hyperreflectivity was observed in all cases of OSSN and pannus. Epithelial thickening was observed in all cases of OSSN, but in none of the cases of pannus. An important distinction between the 2 groups was the transition between normal and abnormal epithelium. All cases of OSSN had a vertical transition, whereas all cases of pannus had an angled transition. CONCLUSIONS: Corneal OSSN and corneal pannus can both present with clinical findings of an opalescent lesion and may have overlapping findings on HR-OCT. Although both entities may show epithelial hyperreflectivity on HR-OCT, OSSN demonstrates an abrupt transition at a vertical, 90 degrees angle perpendicular to the Bowman layer, whereas pannus appears as an angled transition around 45 degrees. Therefore, the angle of transition between normal and abnormal epithelium can be useful in distinguishing between the 2 entities.

Face and Content Validity of an Artificial Eye Model for Secondary Intraocular Lens Fixation via Yamane Technique.

Purpose: To assess the face and content validity of an artificial eye model for secondary intraocular lens (IOL) fixation via the Yamane technique. Methods: Ophthalmologists and residents participated in a 90-minute simulation session on secondary IOL fixation via the Yamane technique. Hands-on practice of this technique was performed on an artificial eye, the Bioniko Okulo BR8. After, all ophthalmologists answered an 18-question survey assessing the face and content validity of the model. Survey responses were recorded on a 5-point double-headed Likert scale, ranging from strongly agree (1)-to-strongly disagree (5) (Figure 1). Results: Twenty-three surveys were completed. Respondents rated the survey with a median response of 1 (strongly agree)-to-3 (neutral). Highest ratings for the model were received for "usefulness for training residents", and "easier to set up and clean-up compared to a cadaver". Lowest ratings were received for realism of the model compared to cadaveric eyes. Statistical analysis revealed no significant difference among identified groups. Ratings for face and content validity were viewed favorably, both with an overall median response of 2.00 (agree). Conclusion: The Bioniko Okulo BR8 shows promise as a valid tool for practicing secondary IOL fixation via the Yamane technique. Considering recent guidelines in competency-based ophthalmology education programs, this model may be a valuable tool over traditional techniques for teaching and improving surgical skill amongst trainees.

Comparison of 3D heads-up display system with conventional surgical microscopy for minimally invasive glaucoma surgery on an artificial eye model.

OBJECTIVE: To survey ophthalmic surgeons' opinions comparing a novel three-dimensional (3D) heads-up display system with a conventional surgical microscopy for minimally invasive glaucoma surgery (MIGS) on an artificial eye model. MATERIALS AND METHODS: Twenty-one ophthalmologists at the 2021 Canadian Ophthalmological Society Annual Meeting in Halifax, Nova Scotia, underwent a 90-minute skills-transfer course on MIGS. Using an artificial eye model (SimulEYE iTrack Model; InsEYE LLC, Westlake Village, Calif.), participants engaged in hands-on practice of MIGS via both a 3D heads-up display system (3D HUDS) (Zeiss Artevo 800; Carl Zeiss Meditec, Jena, Germany) and a conventional surgical microscope. Following completion, participants and instructors answered a 16-question survey comparing the 2 systems (3D HUDS vs conventional surgical microscope). Survey responses were recorded on a 9-point double-headed Likert scale ranging from strongly favour 3D HUDS (1) to strongly favour conventional surgical microscopy (9). Mann-Whitney U nonparametric analysis was used to compare instructor versus participants and experts versus nonexperts. RESULTS: Survey ratings favoured the 3D HUDS over the conventional surgical microscopy, with respondent ratings for all survey questions ranging from a response of 1 (strongly favour 3D HUDS) to 5 (equal). Mann-Whitney U statistical analysis revealed no significant difference between instructor versus participant as well as between expert versus nonexpert. Most ratings for the 3D HUDS were received for ergonomic setup of the surgical modality, depth of field (or) field of view, and usefulness in training residents for MIGS. Equal ratings for the 3D HUDS and conventional surgical microscope were received for system malfunctions and lag during surgery. CONCLUSIONS: The 3D HUDS was favoured over conventional microscopy for the performance of simulated MIGS by ophthalmologists with varying levels of experience. The survey results suggest that the 3D HUDS in an artificial eye model is useful for teaching minimally invasive glaucoma surgery, particularly with the advent of competency-based ophthalmology education programs.

Emergence Agitation and Anesthetic Considerations in the Management of Patients With Post-Traumatic Stress Disorder: A Report of Two Cases and a Review of the Literature.

Post-traumatic stress disorder (PTSD) is a psychological disturbance resulting from exposure to a traumatic experience that lasts more than one month. PTSD in the United States has a lifetime prevalence of 3.4% to 26.9% in civilians and 7.7% to 17.0% in military veterans. Emergence agitation (EA) and emergence delirium (ED) are known phenomena in the postanesthetic period. PTSD is closely associated with EA following anesthesia. In addition, EA in patients with PTSD can be severe and challenging to manage. EA is a risk to both patients and healthcare workers. Furthermore, EA has been shown to increase the overall risk of postoperative delirium and complications. Currently, studies on the anesthetic management of patients with PTSD are scarce and limited to case reports. Here, we present a summary of several important published case reports and a brief review of the literature regarding the anesthetic management of PTSD and EA to aid in managing patients with PTSD. In addition, we present two cases of successful EA prevention in patients with severe PTSD. From our review of the literature and the successful prevention of EA in our patients with severe PTSD, we conclude that there is an increased need for overall awareness among anesthesia and perioperative care providers of the effect of PTSD on EA. Anesthesia providers should aim to include as many management recommendations as possible and avoid possible triggers of EA via a multidisciplinary approach. Multiple pharmacological agents have been used for the anesthetic management of PTSD with varying results. Of the agents studied, dexmedetomidine has been found to be the most consistently beneficial.

Successful Management of a Patient With a History of Postoperative Delirium Undergoing Cardiac Surgery With an Erector Spinae Plane Block and Multimodal Analgesia: A Case Report.

Perioperative delirium is an acute confusional state with fluctuating levels of consciousness, which can be precipitated by opioid-based anesthetics and inadequate pain control, especially in patients undergoing cardiac surgery. We seek to minimize opioid usage to avoid postoperative delirium in a patient with multiple risk factors undergoing aortic valve replacement. We used cardiac enhanced recovery after surgery protocols (ERAS-C), which include multimodal analgesia and regional anesthesia via bilateral erector spinae plane (ESP) blocks. Our observations suggest that bilateral ESP blocks and cardiac ERAS protocols offer a potential option to manage pain and control risk factors in patients at high risk of postoperative delirium undergoing cardiac surgery.

Pectointercostal fascial plane block for rescue pain management of traumatic sternal fracture following inadequate thoracic epidural block: a case report.

Adequate pain control after multisystem trauma including the chest wall is essential for improved patient outcomes, especially with sternum and rib fractures. The thoracic epidural is considered the gold standard in pain management of thoracic injury; however, failure or patchy epidural is not uncommon. Pectointercostal fascial plane block (PIFB) is regularly used in cardiac surgery to provide analgesia to the anterior chest wall; however, there are few reports of PIFB being used as a primary block for the management of thoracic injuries. We present a case in which PIFB was used as a rescue block for the successful management of sternal pain following patchy thoracic epidural block in a patient with thoracic polytrauma.

Perioperative Evaluation of Infective Endocarditis Via Multimodality Imaging for the Surgical Management of Aortic Root Abscess.

Infective endocarditis (IE) is an infection of the endothelium of the heart, that typically affects heart valves. While echocardiography remains crucial in the diagnosis and management of IE, multimodality cardiac imaging helps obtain additional information for the management of complex cases. Alternative imaging modalities such as computed tomography (CT), computed tomography angiography (CTA), and magnetic resonance imaging (MRI) are playing an increasing role in the diagnosis and management of IE, especially for patients with prosthetic valve endocarditis (PVE). Here we present a case of a 60-year-old Caucasian male who was diagnosed with IE, complicated by aortic root abscess, and multiorgan failure. In this challenging case, multimodality cardiac imaging helped in the precise understanding of the extent of endocarditis, cannulation strategy, and direct the course of the surgical procedure that resulted in successful patient management.

Tumor-associated macrophage infiltration in meningioma.

BACKGROUND: Meningioma, a most common brain tumor, has a high rate of recurrence. Tumor-associated macrophages (TAMs) are the most abundant immune cell type in meningioma. TAMs display functional phenotypic diversity and may establish either an inflammatory and anti-tumoral or an immunosuppressive and pro-tumoral microenvironment. TAM subtypes present in meningioma and potential contribution to growth and recurrence is unknown. METHODS: Immunofluorescence staining was used to quantify M1 and M2 TAM populations in tissues obtained from 30 meningioma patients. Associations between M1 and M2 cells, M1:M2 cell ratio to tumor characteristics, WHO grade, recurrence, size, location, peri-tumoral edema, and patient demographics such as age and sex were examined. RESULTS: TAM cells accounted for ~18% of all cells in meningioma tissues. More than 80% of infiltrating TAMs were found to be of pro-tumoral M2 phenotype and correlated to tumor size (P = .0409). M1:M2 cell ratio was significantly decreased in WHO grade II, compared to grade I tumors (P = .009). Furthermore, a 2.3-fold difference in M1:M2 ratio between primary (0.14) and recurrent (0.06) tumors was observed (n = 18 and 12 respectively, P = .044). CONCLUSION: This study is the first to confirm existence of pro-tumoral M2 TAMs in the meningioma microenvironment, emphasizing its potential role in tumor growth and recurrence.

Cryopreserved Allograft in the Management of Native and Prosthetic Aortic Infections.

BACKGROUND: The management of patients with aortic native and prosthetic infections is associated with significant morbidity and mortality. We describe a single-center experience with the use of cryopreserved allografts for the treatment of aortic infections, and compare outcomes with rifampin-soaked grafts and extra-anatomic bypass. METHODS: We retrospectively reviewed all patients who underwent an operative intervention for aortic infection at our tertiary care center from August 2007 to August 2017. Demographic data, preoperative work-up, procedural details, and outcomes were collected for each treatment modality. RESULTS: Thirty-two patients had aortic revascularization for aortic infection. Seventeen patients had cryopreserved allografts, 10 had rifampin-soaked grafts, and 5 had extra-anatomic bypass. Sixteen patients (50%) had native aortic infection and 16 patients (50%) had prosthetic aortic infection. Eighteen had involvement of the infrarenal abdominal aorta, 12 of the paravisceral aorta, and 2 of the descending thoracic aorta. Early mortality was 5.9% (1/17) for the cryopreserved group, 10% (1/10) for the rifampin-soaked group, and 40% (2/5) for the extra-anatomic bypass group. Early graft-related complications occurred in 1 patient (cryopreserved group). Mean follow-up was 34.8 months. Late death occurred in 4 patients with cryopreserved allografts, 2 with rifampin-soaked grafts and none with extra-anatomic bypass. Late graft-related complications occurred in 4 patients (cryopreserved group). Only 1 patient had recurrence of aortic infection (cryopreserved group) and 2 patients had limb loss (1 from the cryopreserved group and 1 from the rifampin-soaked group). At 1 month, 6 months, 1 year, and 3 years, estimated survival for patients with cryopreserved allografts was 94%, 82%, 75%, and 64%, respectively. CONCLUSIONS: The management of aortic infections is challenging. In patients who do not need immediate intervention, in situ aortic reconstruction with cryopreserved allografts is a viable treatment modality with relatively low morbidity and mortality.

Survival after abdominal aortic aneurysm repair is affected by socioeconomic status.

OBJECTIVE: The association between socioeconomic status (SES) and outcome after abdominal aortic aneurysm (AAA) repair is largely unknown. This study aimed to determine the influence of SES on postoperative survival after AAA repair. METHODS: Patients undergoing surgical treatment of AAA at a tertiary referral center between January 1993 and July 2013 were retrospectively collected. Thirty-day postoperative mortality and long-term mortality were documented through medical record review and the Michigan Social Security Death Index. SES was quantified using the neighborhood deprivation index (NDI), which is a standardized and reproducible index used in research that summarizes eight domains of socioeconomic deprivation and is based on census tracts derived from patients' individual addresses. The association between SES and survival was studied by univariable and multivariable Cox regression analysis. RESULTS: A total of 767 patients were included. The mean age was 73 years; 80% were male, 77% were white, and 20% were African American. There was no difference in SES of patients who underwent open vs endovascular repair of AAA (P = .489). The average NDI was -0.18 (minimum, -1.47; maximum, 2.35). After adjusting for the variables that were significant on univariable analysis (age, medical comorbidities, length of stay, and year of surgery), the association between NDI and long-term mortality was significant (P = .021; hazard ratio, 1.21 [1.05-1.37]). CONCLUSIONS: Long-term mortality after AAA repair is associated with SES. Further studies are required to assess which risk factors (behavioral, psychosocial) are responsible for this decreased long-term survival in low SES patients after AAA repair.

The effect of electronic health record software design on resident documentation and compliance with evidence-based medicine.

This study aimed to determine the role of electronic health record software in resident education by evaluating documentation of 30 elements extracted from the American Academy of Ophthalmology Dry Eye Syndrome Preferred Practice Pattern. The Kresge Eye Institute transitioned to using electronic health record software in June 2013. We evaluated the charts of 331 patients examined in the resident ophthalmology clinic between September 1, 2011, and March 31, 2014, for an initial evaluation for dry eye syndrome. We compared documentation rates for the 30 evidence-based elements between electronic health record chart note templates among the ophthalmology residents. Overall, significant changes in documentation occurred when transitioning to a new version of the electronic health record software with average compliance ranging from 67.4% to 73.6% (p < 0.0005). Electronic Health Record A had high compliance (>90%) in 13 elements while Electronic Health Record B had high compliance (>90%) in 11 elements. The presence of dialog boxes was responsible for significant changes in documentation of adnexa, puncta, proptosis, skin examination, contact lens wear, and smoking exposure. Significant differences in documentation were correlated with electronic health record template design rather than individual resident or residents' year in training. Our results show that electronic health record template design influences documentation across all resident years. Decreased documentation likely results from "mouse click fatigue" as residents had to access multiple dialog boxes to complete documentation. These findings highlight the importance of EHR template design to improve resident documentation and integration of evidence-based medicine into their clinical notes.
