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.

A Review of Current Uses of Amniotic Membrane Transplantation in Ophthalmic Plastic and Reconstructive Surgery.

PURPOSE: To review and summarize the existing literature on the clinical applications of amniotic membrane transplantation (AMT) in ophthalmic plastic and reconstructive surgery. METHODS: A literature review was conducted on the PubMed database using the following search terms: "amniotic membrane" and "eyelid" or "orbit" or "fornix" or "socket" or "lacrimal". RESULTS: In total 516 articles resulted from the search, of which 62 were included. Numerous cases and case series have been published on the use of amniotic membrane transplantation for ocular surface reconstruction, eyelid and forniceal reconstruction, and cicatricial eyelid abnormalities. Surgical methods of securing the graft vary. Few comparative studies exist; some show a similar or improved result when compared to oral mucous membrane grafting for certain indications. CONCLUSIONS: Amniotic membrane transplantation can be a useful tool for the oculoplastic surgeon when faced with a case requiring reconstruction of the posterior lamellae, particularly in patients without other graft donor sites available, and uses of AMT continue to expand. Additional studies directly comparing AMT to other reconstructive techniques would be helpful in choosing between the available surgical techniques and standardizing best practices.

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.

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.

Bilobed flap reconstruction after en-bloc removal of solitary fibrous tumor of the lacrimal sac.

Purpose: To report a rare case of a solitary fibrous tumor (SFT) of the lacrimal sac and discuss considerations for management of similar cases. Observations: We present the case of a 41-year-old woman who presented with a primary lacrimal sac SFT for which she underwent en-bloc surgical resection. We discuss management options for SFTs and our surgical approach for this case: bilobed flap reconstruction of the medial canthus and inferior orbit. Conclusions: We present an uncommon presentation of a rare tumor and a successful one-stage reconstruction with a bilobed flap.

Implants and spacers for paralytic ectropion: Literature review and assessment of a thin-profile porous polyethylene implant.

Purpose: There is no ideal treatment paradigm for paralytic ectropion. This study evaluated lower eyelid spacers and the efficacy of a novel lower eyelid thin profile, bio-integratable, porous polyethylene. Methods: A retrospective review of 15 consecutive patients who underwent thin-profile porous polyethylene implantation and canthoplasty for paralytic ectropion was carried out. A comprehensive literature review of spacers for paralytic ectropion and retraction using the Pubmed database with search terms "[implant or graft or spacer] and [paralytic ectropion or paralytic retraction]," "graft and paralysis and ectropion," "implant and paralysis and ectropion," "graft and paralysis and retraction," and "implant and paralysis and retraction" was carried out. Results: The mean patient age was 69 years (range: 50-88). Lagophthalmos improved from a mean of 5.7 mm (SD = 3.3, range 3-14 mm) to 1.4 mm (SD = 1.1, range 0-3.5 mm), P < 0.0001. MRD 2 improved from a mean of 6.7 mm (SD = 2.3, range 2-12 mm) to 4.2 mm (SD = 0.9, range 3-6 mm), P = 0.0005. No patients needed additional lower eyelid surgery. There were no implant exposures at a mean follow-up of 7.6 months (SD = 7.9, range 0.7-21.6 months). Detailed literature review revealed that hard palate and ear cartilage are the most reported spacers, each with unique disadvantages. Conclusion: The thin-profile porous polyethylene implant is a useful addition to the management of symptomatic paralytic ectropion. Meaningful comparison of lower eyelid spacers is difficult because of variations in surgical technique, spacer size, and poorly reported outcome data. No spacer proves superior.

Multiple Cases of Facial Disfigurement From Filler Use and One Injector.

PURPOSE: To present a case of facial disfigurement from an injectable permanent filler and describe the consequences to patients exposed to the same injector (common source outbreak). METHODS: Case report and discussion of a common source outbreak after a group of persons developed complications years after permanent filler given by one injector. RESULTS: A 39-year-old transgender model underwent polymethylmethacrylate (Artefill) facial filler injections to the lips, cheeks, and chin in 2018. A year later, the patient presented to the emergency room with severe facial swelling and difficulty breathing. Treatments have included 4 surgeries to remove filler and scar tissue and chronic low-dose oral steroid therapy. Upon questioning the patient, 6 additional people suffered from similar facial swelling years after injection by the same injector. The injector cannot be located. CONCLUSIONS: Care must be taken in giving all facial fillers, particularly permanent ones. When one source patient is identified, questioning the patient's knowledge of others affected is critical to help manage an epidemic problem and to report a rogue injector. Physicians have a duty to investigate and report such cases.

Prevalence and Causes of Subconjunctival Hemorrhage in Children.

OBJECTIVE: Subconjunctival hemorrhage (SCH) is a reported sign of occult abusive injury, but there are limited published data about SCH during childhood. We sought to determine the prevalence and causes of SCH in children. METHODS: This is a retrospective cross-sectional study of children seen by pediatric ophthalmologists in an outpatient setting over 4 years. Primary outcomes were prevalence and causes of SCH, based on history, physical ocular and nonocular findings, and laboratory and imaging studies. Subconjunctival hemorrhage prevalence was determined including and excluding eye surgery to reduce bias in the prevalence estimate. RESULTS: We studied 33,990 children, who underwent 86,277 examinations (median age, 5 years; range, 2 days to 18 years; 9282 younger than 2 years, 13,447 age 2-7 years, 11,261 age 8-18 years). There were 949 cases of SCH (1.1%; 95% confidence interval, 1.0-1.2). When surgery was excluded, there were 313 cases (prevalence, 0.4%; 95% confidence interval, 0.3-0.4), of which 261 (83%) were due to trauma; 40 (13%) ocular surface inflammation, including infectious conjunctivitis; 7 (2%) orbital or conjunctival lesion; 3 (1%) vessel rupture from choking or cough; and 2 (1%) coagulopathy related. Across all ages, including less than 2 years, trauma and inflammation together accounted for 94% to 97% of all cases of SCH. CONCLUSIONS: Subconjunctival hemorrhage is uncommon in children. The great majority of cases are due to trauma. All children with SCH, including infants and young children, should be closely examined to identify other ocular or nonocular signs of trauma.

Timing is everything: Where status epilepticus treatment fails.

Status epilepticus is an emergency; however, prompt treatment of patients with status epilepticus is challenging. Clinical trials, such as the ESETT (Established Status Epilepticus Treatment Trial), compare effectiveness of antiepileptic medications, and rigorous examination of effectiveness of care delivery is similarly warranted. We reviewed the medical literature on observed deviations from guidelines, clinical significance, and initiatives to improve timely treatment. We found pervasive, substantial gaps between recommended and "real-world" practice with regard to timing, dosing, and sequence of antiepileptic therapy. Applying quality improvement methodology at the institutional level can increase adherence to guidelines and may improve patient outcomes. Ann Neurol 2017;82:155-165.
