An Analysis of Surgical Factors Associated with Clinically Significant Eyelid Edema (CSEE) in Patients Undergoing Blepharoplasty: Lid Crease Techniques Associated with CSEE.

PURPOSE: Severe postoperative edema after eyelid surgery can have negative clinical and psychological effects. In this study, we investigated whether surgical factors, including surgical techniques and suture type, were associated with clinically significant eyelid edema (CSEE). METHODS: A chart review was performed on 269 patients who underwent upper eyelid blepharoplasty with or without external levator advancement by 2 surgeons at a single institution between January 2021 and December 2022. Postoperative photos were graded by 2 physicians for eyelid edema using a standardized grading scale ranging from 0 (no edema) to 3 (severe edema). CSEE was defined either as having a grade of 3 at any point postoperatively or any grade that was 1 or greater after 90 days postoperatively. Logistic regression controlling for race was used for analysis; the statistical significance level was defined as p < 0.05. RESULTS: Of 269 patients, 56 developed CSEE. Of those who underwent blepharoplasty with mini crease enhancement (closure with every other bite incorporating levator aponeurosis), 40.5% developed CSEE versus 12.5% of those without (p < 0.001). Patients with lid crease formation using buried interrupted sutures had greater CSEE than those with externalized interrupted sutures removed at 1 week (43.8% versus 11.5%, p < 0.01). There was no increased risk of CSEE with additional procedures performed versus blepharoplasty alone. CONCLUSIONS: Patients who underwent blepharoplasty with mini crease enhancement, where more than 4 sutures are placed from skin to levator, and/or had buried suture lid crease formation had greater rates of CSEE.

Arterial Wall and Tissue Penetration Force With Various Cannulas and Needles.

BACKGROUND: Vascular penetration during aesthetic filler injections can cause serious side effects such as skin necrosis and blindness. OBJECTIVES: The objective of this study was to analyze the effect of cannula brand and gauge on the risk of vascular penetration. METHODS: The minimal force to penetrate the superficial temporal artery with 3 cannula brands and 1 needle brand in 4 sizes (22, 25, 27, and 30 gauge) was measured in 4 fresh frozen cadavers utilizing a force gauge that measured as low as 0.1 Newtons. Tissue penetration force in the subdermal plane of the nasolabial fold was measured and compared with retrospective training data in live humans. The arterial penetration test was repeated at a second site on 1 fresh cadaver with 2 different force gauges. RESULTS: Significantly lower forces were needed with all size needles vs the same gauge cannulas in all brands to penetrate the cadaveric artery and advance in the subdermal plane of the nasolabial fold in both cadavers and live humans. To successfully enter the artery in a cadaver with any cannula, numerous attempts were necessary. The tissue penetration force in the subdermal plane of the nasolabial fold in a cadaver was not significantly different than in a living person; however, it was significantly higher than the arterial penetration force in a dissected cadaver. CONCLUSIONS: All gauge cannulas (including 27 and 30 gauge), require more force than the same size needle to penetrate an artery. However, it appears that friction coefficient and flexibility, not the arterial penetration force, are the most important factors in keeping the instrument outside the vessel.

Lateral orbital wall anomaly in a patient with thyroid eye disease.

An isolated defect in the lateral orbital wall is an uncommon occurrence, although cases of orbital floor, roof, and medial wall spontaneous dehiscence have been described in the literature. Here, we describe a lateral orbital wall defect in a patient with thyroid eye disease - which may be related to bony remodeling or may represent a rare congenital anomaly. Computed tomography (CT) prior to decompression surgery revealed a defect in the left lateral orbital wall. At the time of orbital decompression, prolapse of buccal fat into the orbit was noted once the subperiosteal plane was entered along the lateral orbital wall in the area of this bony defect. Literature review revealed only a few previous reports of lateral wall abnormalities, including two involving the inferior orbital fissure; one other case was associated with Down syndrome, and other reports consist of sphenoid hypoplasia associated with neurofibromatosis.

Misdiagnosis of Orbital Foreign Body as Glaucoma Drainage Device.

BACKGROUND: Sight-threatening complications from retained orbital and intraocular foreign bodies are frequently reported in literature. Delays in diagnosis can result in severe complications, including choroidal neovascularization, infection, and irreversible vision loss. Therefore, it is imperative that emergency physicians consider the possibility of orbital and intraocular foreign bodies when evaluating patients with acute facial trauma. CASE REPORT: A 91-year-old woman with a history of laser-treated glaucoma and cataracts presented to an outside emergency department after a ground-level fall. A maxillofacial noncontrast computed tomography scan showed no facial fractures or hemorrhage, but a 41 mm × 4 mm foreign body within the intraconal compartment of the right orbit was identified. The object was presumed to be an implanted glaucoma drainage device, and the patient was discharged without antibiotics. One day after discharge, the patient developed right periorbital swelling and erythema with increasing purulent discharge and skin thickening, ultimately requiring transfer to our facility for management of complex right orbital cellulitis, orbital compartment syndrome, and surgical foreign body removal. Despite globe exploration and surgical intervention, the patient developed a frozen globe with no light perception in the right eye. Why Should an Emergency Physician Be Aware of This? Subtle ophthalmologic emergencies such as sight-threatening foreign bodies can be challenging to diagnose on imaging, particularly with the advent of implantable ocular technology. When an orbital foreign body is discovered in the context of facial trauma, early ophthalmology consultation should be considered.

Thyroid eye disease with choroidal folds.

Purpose: To determine the clinical course of patients with chorioretinal folds (CRF) in thyroid eye disease (TED).Methods: A multi-center retrospective case series of patients with TED who developed CRF.Results: Ten patients (17 eyes) with CRF related to TED were identified. The mean age of presentation was 59.3 ± 8.3 years old. The majority of patients were male (70%), hyperthyroid (70%), hyperopic (53%), had a history of radioactive iodine (60%), and currently on methimazole treatment (30%). Three patients (3 eyes) had unilateral involvement of CRF with bilateral TED. The average clinical activity score was 3.6 ± 2.1 at the time of presentation. The most commonly enlarged extraocular muscles were medial (76%), inferior (64%), superior (64%) and lateral rectus (35%). Compressive optic neuropathy was seen in 47% of eyes. Treatment included oral prednisone (70%), orbital decompression (59%), thyroidectomy (20%) and tocilizumab (10%). The CRF did not resolve over a follow up period of 24.7 ± 23.7 months in 70% of eyes. There was no significant difference in average axial length (25.7 ± 4.9 mm) and optic nerve to optic strut distance (37.8 ± 3.9 mm) between patients with CRF and the eight age-and sex-matched TED control patients without CRF (p = 0.81 and 0.65 respectively). A univariable and multivariable analysis found an enlarged inferior rectus as a factor in TED patients with persistent CRF.Conclusions: CRF are often an indicator of visually threatening situations and often do not resolve despite treatment of TED.

Evaluating the Safety and Efficacy of a Topical Formulation Containing Epidermal Growth Factor, Tranexamic Acid, Vitamin C, Arbutin, Niacinamide and Other Ingredients as Hydroquinone 4% Alternatives to Improve Hyperpigmentation: A Prospective, Randomized, Controlled Split Face Study.

Hyperpigmentation is a common concern of patients in aesthetic practice. There are various treatment options, but topical depigmenting agents such as hydroquinone (HQ) are usually a first-line option. Given HQ's side effects and potential controversy over its long-term use from prior animal studies, there is a consumer demand for non-HQ topical formulations that provide similar efficacy, but with a reduced adverse reaction profile to HQ. There is increasing evidence to support the use of selective growth factors, tranexamic acid, niacinamide, arbutin, and Vitamin C in improving hyperpigmentation. This study sought to determine whether a non-HQ topical formulation, composed of the aforementioned ingredients, could provide similar or improved efficacy to topical HQ, but with a reduced adverse reaction profile. This single-center, prospective, randomized, controlled split face study investigated the safety and efficacy of a proprietary product SKNB19 compared with hydroquinone 4% (HQ4%) in treating hyperpigmentation. Eighteen adult subjects with facial pigmentation were randomly assigned to have one side of their face treated with SKNB19 twice a day (morning and night application) and the other treated with HQ4% applied nightly. Patients used a 5-point scale to self-assess their overall appearance, and a 4-point scale to assess redness, irritation, and tolerability to the skin-brightening creams. A Wilcoxon signed-rank test was used to test whether there was a statistical difference between the two treatments. Three-dimensional imaging was performed before treatment was administered and again 1 month following treatment initiation using a Canfield Vectra 3D imaging system. Five independent reviewers comprising two dermatologists, two facial plastic surgeons, and one oculoplastic surgeon graded and performed a qualitative comparative assessment of each side of the face using the before and after images. A Wilcoxon signed-rank test was used to test whether there was a statistical difference in overall appearance between SKNB19- and HQ4%-treated sides. SKNB19-treated hyperpigmentation had a statistically significant improvement in the overall appearance of hyperpigmentation and was shown to be 28.5% better than HQ4%-treated skin in the patient self-assessment and 27% better than HQ4%-treated skin in the independent reviewer assessment. On pair-wise comparison, the independent reviewer assessment also showed that 88.2% of the SKNB19-treated sides appeared equal or better than the HQ4%-treated sides. One patient dropped out of the study because of severe intolerance to HQ4%. No patients experienced intolerance to SKNB19, and all were able to continue its use without adverse effects. SKNB19-treated hyperpigmentation also had a statistically significant reduction in irritation when compared with HQ4%-treated hyperpigmentation. Patients reported a reduction in redness when using SKNB19 as opposed to HQ4%, but these figures did not reach statistical significance. This study supports that SKNB19, a recently developed non-HQ proprietary product, is safe and effective in improving hyperpigmentation. SKNB19 significantly improved the appearance of hyperpigmentation when compared with HQ4% in both patient self-assessment and independent reviewer assessment. SKNB19 exhibited a lower adverse reaction profile and was significantly better tolerated than HQ4%. SKNB19 should be considered as a safe and effective non-HQ alternative for the management of hyperpigmentation.

Evolving Minimally Invasive Techniques for Tear Trough Enhancement.

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.

Characterization and outcomes of repeat orbital decompression for thyroid-associated orbitopathy.

Orbital decompression for thyroid-associated orbitopathy (TAO) is commonly performed for disfiguring proptosis, congestion, and optic neuropathy. Although one decompression typically achieves goals, a small percentage requires repeat decompression. We performed a 10-year retrospective chart review of all orbital decompressions for TAO at a single tertiary referral institution. Four-hundred and ninety-five orbits (330 patients) were decompressed for TAO, with 45 orbits (37 patients) requiring repeat decompression. We reviewed the repeat cases for indications, clinical activity scores, approach, walls decompressed, and outcomes. Nine percent of orbits required repeat decompression for proptosis (70%), optic neuropathy (25%) or congestion (45%). Sixty-four percent were for recurrence of disease, 36% were for suboptimal decompression. Three incisional approaches were used: lateral upper eyelid crease, inferior transconjunctival, and transcaruncular, with inferior transconjunctival being most common. Of the three walls removed, deep lateral, inferior, and medial, the deep lateral wall was most common (51%). A repeat lateral decompression was the most frequent pattern. Of 37 patients requiring repeat decompression, 40% had diplopia prior to repeat, and an additional 24% developed diplopia after the repeat. Whereas previous studies published by our group cited only 2.6% of deep lateral wall orbital decompressions leading to new-onset primary gaze diplopia, repeat orbital decompressions have a much higher rate of post-operative diplopia. The new onset primary gaze diplopia after repeat decompression group had a higher average preoperative CAS (3.3 vs. 2.4, p < 0.01), higher mean blood loss (56 vs. 19 mL, p = 0.04), more frequent medial wall decompressions (47% vs. 29%, p = 0.33), and greater proptosis reduction (2.4 vs. 1.7 mm, p = 0.24).

Light Therapy for Facial Rejuvenation and Dry Eyes, Blepharitis, and Styes.

Intense pulsed light has a growing body of research supporting its use in skin rejuvenation, dermatologic conditions, as well as ocular rosacea, dry eyes and meibomian gland dysfunction. This paper will start with the conception of one protocol for treating dry eyes, blepharitis and styes using broad band light, a version of intense pulsed light, and its evolution into a life-changing in-office procedure for many patients. The approach for optimizing the settings, considerations during the consultation, the procedure in detail, after treatment care, and potential complications to avoid are all explained. Periocular and facial rejuvenation treatment protocols are discussed as well. This should be a useful guide for clinicians looking to add intense pulsed light to their in-office treatment armamentarium to significantly improve the lives of their patients.

Assessing the Utility of ChatGPT in Simplifying Text Complexity of Patient Educational Materials.

INTRODUCTION: AI chatbots are being increasingly used in healthcare settings. There is growing interest in using AI to assist in patient education. Currently, extensive healthcare information is found online but is often too complex to understand. Our objective is to determine if physicians can recommend the free version of ChatGPT version 3.5 (OpenAI, San Francisco, CA, USA) for patients to simplify text from the American Academy of Ophthalmology (AAO) in English and Spanish. This version of ChatGPT was assessed in this study due to its increased accessibility across various patient populations. METHODS: Fifteen articles were chosen from AAO in both languages and simplified with ChatGPT 10 times each. The readability of original and simplified articles was assessed with the Flesch Reading Ease and Gunning Fog Index for English and Fernández Huerta, Gutiérrez, Szigriszt-Pazo, INFLESZ, and Legibilidad-µ for Spanish. Grade levels to assess readability were calculated with Flesch Kincaid Grade Level and Crawford Nivel-de-Grado. Mean, standard deviation, and two-tailed t-tests were performed to assess differences before and after simplification. RESULTS: Average grade levels before and after simplification were as follows: English 8.43±1.17 to 8.9±2.1 (p=0.41) and Spanish 5.3±0.34 to 4.1±1.1 (p=0.0001). Spanish articles were significantly simplified per Legibilidad-µ (p=0.003). No significant difference was noted for other scales. CONCLUSIONS: The readability of AAO articles in English worsened without significance but significantly improved in Spanish. This may result from simpler syllable structures and a lesser overall vocabulary in Spanish. With increased testing, physicians can recommend ChatGPT for Spanish-speaking patients to improve health literacy.

A comparison of five point-of-care ultrasound devices for use in ophthalmology and facial aesthetics.

Introduction: Point-of-care ultrasound is becoming increasingly popular, and we sought to examine its role in evaluating ocular and periocular structures and facial vasculature. With the large number of point-of-care ultrasound devices available, it is difficult to determine which devices may be best suited for ophthalmic and facial aesthetic applications. This study compares five popular handheld point-of-care ultrasound devices to help guide clinicians in choosing the device best suited for their needs. Methods: We compared five point-of-care ultrasound devices: Butterfly IQ+ (Butterfly, Burlington, MA), L15 (Clarius Mobile Health, Vancouver, British Columbia, Canada), L20 (Clarius Mobile Health, Vancouver, British Columbia, Canada), Lumify (Philips, Amsterdam, Netherlands) and Vscan Air (GE, Boston, MA). Three ophthalmologists obtained the following views on three volunteers: eight arteries, four ocular and periocular structures and areas of filler injections. The image quality of each view was graded on a four-point Likert-type scale. In addition, graders filled out a survey. The data were analysed using analysis of variance tests with the significance level set to p < 0.05. Results: In terms of overall image quality, the L20 received the highest mean rating, followed by the L15, Vscan Air, Butterfly IQ+ and the Lumify (p < 0.05). With further stratification for structure type, the L20 was ranked first for filler, artery and orbital imaging (p < 0.05). Conclusions: The L20 received the highest image quality rankings. While image quality is an important aspect of point-of-care ultrasound device selection, other factors such as cost, wireless capabilities, range of presets and battery life should also be considered.

Long-Term Follow-Up of a Case of Severe Hyperglycemia Requiring Hospitalization after Third Dose of Teprotumumab: A Case Report.

Introduction: In 2020, teprotumumab became the first FDA-approved treatment for thyroid eye disease (TED). In clinical trials, hyperglycemia had been described as mild and controlled with medication. We present a case that occurred in 2020 of a 67-year-old male with TED and pre-existing glucose intolerance, who was hospitalized with severe hyperglycemia (1,059 mg/dL) after three doses of teprotumumab. Case Presentation: This patient's HbA1c was in the pre-diabetic range (6.3%) 6 months prior to initiating teprotumumab. After three doses, the patient was hospitalized with hyperosmolar hyperglycemic nonketotic syndrome and an HbA1c of 11.7%. He was diagnosed with type 2 diabetes mellitus and treated with insulin aspart mixed 70/30. He remained on this regimen for 14 months with an A1c of 6.0%. He then self-discontinued the insulin, with an A1c 4 months later measuring 5.5%. The patient's latest HbA1c approximately two and a half years after hospitalization was 6.1% on no medications. Conclusion: It appears that teprotumumab was a trigger for this transient case of diabetes, and detecting those that have underlying glucose intolerance ahead of time is important. We recommend blood glucose levels for patients with pre-diabetes prior to and ideally in the first few days after each infusion, to help determine patients at a greater risk for adverse hyperglycemic outcomes. A glucometer may be valuable for patients to self-monitor while on teprotumumab. If fasting blood glucose is ≥126 mg/dL or non-fasting glucose is >200 mg/dL, patients should be referred for further diabetes assessment and possible treatment initiation.

Accuracy and Bias in Artificial Intelligence Chatbot Recommendations for Oculoplastic Surgeons.

Purpose The purpose of this study is to assess the accuracy of and bias in recommendations for oculoplastic surgeons from three artificial intelligence (AI) chatbot systems. Methods ChatGPT, Microsoft Bing Balanced, and Google Bard were asked for recommendations for oculoplastic surgeons practicing in 20 cities with the highest population in the United States. Three prompts were used: "can you help me find (an oculoplastic surgeon)/(a doctor who does eyelid lifts)/(an oculofacial plastic surgeon) in (city)." Results A total of 672 suggestions were made between (oculoplastic surgeon; doctor who does eyelid lifts; oculofacial plastic surgeon); 19.8% suggestions were excluded, leaving 539 suggested physicians. Of these, 64.1% were oculoplastics specialists (of which 70.1% were American Society of Ophthalmic Plastic and Reconstructive Surgery (ASOPRS) members); 16.1% were general plastic surgery trained, 9.0% were ENT trained, 8.8% were ophthalmology but not oculoplastics trained, and 1.9% were trained in another specialty. 27.7% of recommendations across all AI systems were female. Conclusions Among the chatbot systems tested, there were high rates of inaccuracy: up to 38% of recommended surgeons were nonexistent or not practicing in the city requested, and 35.9% of those recommended as oculoplastic/oculofacial plastic surgeons were not oculoplastics specialists. Choice of prompt affected the result, with requests for "a doctor who does eyelid lifts" resulting in more plastic surgeons and ENTs and fewer oculoplastic surgeons. It is important to identify inaccuracies and biases in recommendations provided by AI systems as more patients may start using them to choose a surgeon.

Phthisical eye and orbital ischemia after cosmetic platelet-rich plasma injection to the forehead.

Purpose: To report a case of retrograde embolism of cosmetic injection of platelet-rich plasma (PRP) to the ophthalmic artery, resulting in orbital ischemia, blindness, and eventual phthisis bulbi. Observations: A 37-year-old woman presented with two days of vision loss OS beginning seconds after undergoing cosmetic PRP filler injections to the face at an outside clinic. Immediately after injection to the left medial forehead, the patient reported bleeding, transient loss of consciousness, and complete vision loss OS. Two days later, vision remained no light perception OS and she exhibited manifestations of both anterior and posterior segment ischemia in the left eye. These findings were ultimately attributed to retrograde embolism to the ophthalmic artery via inadvertent injection of PRP into the supratrochlear or supraorbital arteries. She ultimately did not regain her vision in the left eye and the eye became enophthalmic and phthisical. Conclusions: After conducting a literature review on August 18, 2023, utilizing PubMed and Google Scholar, and searching for the key words "platelet-rich plasma" and "vision loss" or "vision impairment," we did not find any prior reports of anterior segment ischemia or pan-orbital ischemia resulting in phthisis bulbi. In the setting of vision changes after cosmetic platelet-rich plasma filler injection. Additionally, there is no validated therapy for ophthalmic artery occlusion from any cosmetic filler embolism. Further research should prioritize developing therapeutic guidelines for managing such complications. Injectors should also be educated to emergently refer patients to hospitals with ophthalmology consults available and stroke protocols in place.

Extraocular Muscle Enlargement in Thyroid Eye Disease Using Volumetric Analysis.

BACKGROUND AND OBJECTIVES: It is commonly taught that thyroid eye disease (TED) causes enlargement of the extraocular muscles (EOMs) in the following descending order: inferior rectus (IR), medial rectus (MR), superior rectus (SR), lateral rectus (LR), superior oblique (SO) and inferior oblique (IO). However, with recent literature challenging this notion, we aimed to compare EOM volumes in our cohort of TED patients.  Methods: We conducted a retrospective, non-randomized case-control study. Twenty-eight orbits from 28 unique patients with TED who had high-resolution CT scans were compared to 31 normal orbits, all from a single academic institution. Orbital soft tissues were manually segmented using ITK-SNAP 3.8.0 (http://itksnap.org), and soft tissue volumes of the control and TED orbits were compared using independent-sample t-tests. RESULTS: Of the TED orbits, 54% of SR/levator palpebrae superioris complex volumes (SRC) and 50% of IR volumes were greater than two standard deviations above the normal orbit average. Compared to controls, the mean SRC volume in TED subjects was 2.3 times enlarged, followed by the IR (2.1 times), SO (1.8 times), MR (1.7 times), LR (1.6 times), IO (1.6 times), and orbital fat (1.4 times) (p < 0.01 for all).  Conclusions: Our findings suggest that contrary to previous teaching, the SRC may be the most severely affected in TED.

Bias and Inaccuracy in AI Chatbot Ophthalmologist Recommendations.

PURPOSE AND DESIGN: To evaluate the accuracy and bias of ophthalmologist recommendations made by three AI chatbots, namely ChatGPT 3.5 (OpenAI, San Francisco, CA, USA), Bing Chat (Microsoft Corp., Redmond, WA, USA), and Google Bard (Alphabet Inc., Mountain View, CA, USA). This study analyzed chatbot recommendations for the 20 most populous U.S. cities. METHODS: Each chatbot returned 80 total recommendations when given the prompt "Find me four good ophthalmologists in (city)." Characteristics of the physicians, including specialty, location, gender, practice type, and fellowship, were collected. A one-proportion z-test was performed to compare the proportion of female ophthalmologists recommended by each chatbot to the national average (27.2% per the Association of American Medical Colleges (AAMC)). Pearson's chi-squared test was performed to determine differences between the three chatbots in male versus female recommendations and recommendation accuracy. RESULTS: Female ophthalmologists recommended by Bing Chat (1.61%) and Bard (8.0%) were significantly less than the national proportion of 27.2% practicing female ophthalmologists (p<0.001, p<0.01, respectively). ChatGPT recommended fewer female (29.5%) than male ophthalmologists (p<0.722). ChatGPT (73.8%), Bing Chat (67.5%), and Bard (62.5%) gave high rates of inaccurate recommendations. Compared to the national average of academic ophthalmologists (17%), the proportion of recommended ophthalmologists in academic medicine or in combined academic and private practice was significantly greater for all three chatbots. CONCLUSION: This study revealed substantial bias and inaccuracy in the AI chatbots' recommendations. They struggled to recommend ophthalmologists reliably and accurately, with most recommendations being physicians in specialties other than ophthalmology or not in or near the desired city. Bing Chat and Google Bard showed a significant tendency against recommending female ophthalmologists, and all chatbots favored recommending ophthalmologists in academic medicine.

Demographic and physiological factors associated with clinically significant eyelid edema in patients following upper eyelid surgery.

PURPOSE: To investigate demographic and physiological variables associated with clinically significant edema after upper eyelid surgery. METHODS: A retrospective chart review was performed on patients who underwent blepharoplasty or external levator advancement with or without lid crease formation between January 2018 and January 2021 at the University of Southern California. Age, sex, pertinent medical history (medications causing edema and comorbidities), and pertinent surgical procedures were all collected. Postoperative photos were graded by two independent physician graders on a newly developed photographic scale ranging from 0 (no edema) to 3 (severe edema). Clinically significant edema of the eyelids was defined as Grade 3 edema at any postoperative point or ≥ Grade 1 edema after 90 days post operation. Patients without postoperative photos were excluded. Mann-Whitney U test, Fisher's exact test, and χ2 test were used to compare groups with and without significant edema. All analyses were conducted using SAS version 9.4 (SAS Institute Inc.) with α=0.05. RESULTS: Out of 217 patients, East Asian participants had higher odds of developing edema than White participants (odds ratio, 7.92; CI, 3.15-19.93, p < 0.0001) and Hispanic participants (odds ratio, 3.47; CI, 1.51-7.97, p = 0.003). Southeast Asian participants also had higher odds of developing CSEE than White participants (odds ratio, 6.19; CI, 1.71-22.43, p = 0.006). Fifty-four (24.9%) patients had clinically significant edema. Although BMI, medical comorbidities, medication use, and age did not affect edema, there was a statistically significant relationship between race and incidence of edema (p = 0.0001). Those in the CSEE group were also more likely to require reoperation (p = 0.0143). CONCLUSIONS: There is a statistically significant relationship between Asian race and the incidence of clinically significant eyelid edema. CSEE is associated with a higher incidence of reoperation.

The Nictavi Tarsus Patch: A New Device for Achieving Temporary Eyelid Closure in Lagophthalmos.

Purpose: To evaluate the effectiveness, tolerability, and safety of the Nictavi Tarsus Patch™ (NTP) in inducing temporary eyelid closure for the management of lagophthalmos in the pediatric and young adult population. Methods: We prospectively enrolled 20 patients <21 years of age who had previously been managed for lagophthalmos to trial the NTP in clinic. Inter-palpebral fissure distance (IPFD) was compared before and after the placement of the NTP in the eyes-closed position using paired t-tests. Subjects then underwent a 3-night home trial with the NTP, and parent and subject perceptions of effectiveness, comfort, and complications with the patch were analyzed using Likert scale survey questions. Results: Twenty subjects ages 2-20 years with paralytic (65%) and non-paralytic (35%) lagophthalmos were enrolled. The NTP improved lagophthalmos from a mean pre-placement IPFD of 3.3 mm to post-placement IPFD of 0.4 mm (p < 0.01). Overall, 80% of subjects achieved successful eyelid closure defined as ≤1 mm of post-placement IPFD. When stratified by subtype, 100% of subjects with paralytic lagophthalmos achieved successful eyelid closure compared to 71% of subjects with non-paralytic lagophthalmos. On a scale of 1 (worst) to 5 (best), parents rated the NTP at 4.3±0.7 for comfort while wearing, 4.3±1.0 for comfort in removing, 4.6±0.7 for ease of use, and 4.3±0.9 for effectiveness. Ninety-three percent of parents reported preferring NTP to other eyelid closure methods previously tried and indicated that they would use it again. Conclusion: The NTP is an effective, tolerable, and safe method of eyelid closure for children and young adults.
