Evaluating ChatGPT on Orbital and Oculofacial Disorders: Accuracy and Readability Insights.

PURPOSE: To assess the accuracy and readability of responses generated by the artificial intelligence model, ChatGPT (version 4.0), to questions related to 10 essential domains of orbital and oculofacial disease. METHODS: A set of 100 questions related to the diagnosis, treatment, and interpretation of orbital and oculofacial diseases was posed to ChatGPT 4.0. Responses were evaluated by a panel of 7 experts based on appropriateness and accuracy, with performance scores measured on a 7-item Likert scale. Inter-rater reliability was determined via the intraclass correlation coefficient. RESULTS: The artificial intelligence model demonstrated accurate and consistent performance across all 10 domains of orbital and oculofacial disease, with an average appropriateness score of 5.3/6.0 ("mostly appropriate" to "completely appropriate"). Domains of cavernous sinus fistula, retrobulbar hemorrhage, and blepharospasm had the highest domain scores (average scores of 5.5 to 5.6), while the proptosis domain had the lowest (average score of 5.0/6.0). The intraclass correlation coefficient was 0.64 (95% CI: 0.52 to 0.74), reflecting moderate inter-rater reliability. The responses exhibited a high reading-level complexity, representing the comprehension levels of a college or graduate education. CONCLUSIONS: This study demonstrates the potential of ChatGPT 4.0 to provide accurate information in the field of ophthalmology, specifically orbital and oculofacial disease. However, challenges remain in ensuring accurate and comprehensive responses across all disease domains. Future improvements should focus on refining the model's correctness and eventually expanding the scope to visual data interpretation. Our results highlight the vast potential for artificial intelligence in educational and clinical ophthalmology contexts.

Pilomatrixoma of the ocular adnexa: report of 3 cases with variations in the histopathological findings.

OBJECTIVE: To report the clinical and variations in the histopathological features of pilomatrixoma of the ocular adnexa in 3 young individuals. DESIGN: A retrospective case series was performed with clinical, histological, and immunohistochemical analysis. PARTICIPANTS: Case 1 is an 18-year-old male who presented with a reddish-blue swelling under the left eyebrow. The lesion measured 2 × 1 cm. Case 2 is a 2-year-old female who presented with a reddish-blue nodule inferior to the right eyebrow with telangiectatic vessels. The lesion measured 6 × 4 × 4 mm. Case 3 is a 14-year-old female who presented with a subcutaneous lesion under the right upper eyebrow with fluctuating inflammation. The lesion measured 12 × 3 × 2 mm. Histopathological examination of case 1 disclosed peripheral basaloid cells and central shadow cells containing calcific foci, separated by a transition zone. In case 2, histopathological analysis revealed central calcific foci in islands of shadow cells with more peripheral basaloid cells. In case 3, we observed numerous clusters of shadow cells with focal calcifications, as well as basaloid cells in a disorganized configuration. CONCLUSION: Pilomatrixoma is an uncommon benign skin neoplasm originating from the matrix of the hair root. We describe a spectrum of histopathological findings in pilomatrixoma of the ocular adnexal in 3 young individuals.

Management of orbital rhabdomyosarcoma in a child with Li-Fraumeni syndrome.

This case highlights the management of orbital rhabdomyosarcoma in a child with Li Fraumeni syndrome (LFS). Treatment with chemotherapy and eventual orbital exenteration enabled margin-free control of the tumor. Radiation therapy was avoided to reduce the risk of inducing additional malignancy. Reactive orbital hyperostosis was observed postoperatively and was confirmed with surgical biopsy of the orbital roof. In this case, systemic surveillance imaging, which is necessary in patients with LFS, revealed an adrenal cortical carcinoma.

Systematic Review of the Yield of Temporal Artery Biopsy for Suspected Giant Cell Arteritis.

PURPOSE: To determine the positive yield (utility rate) of temporal artery biopsy (TAB) in patients with suspected giant cell arteritis (GCA). STUDY DESIGN: Systematic review (CRD42017078508) and meta-regression. MATERIALS AND METHODS: All articles concerning TAB for suspected GCA with English language abstracts from 1998 to 2017 were retrieved. Articles were excluded if they exclusively reported positive TAB, or only cases of known GCA. Where available, the pre-specified predictors of age, sex, vision symptoms, jaw claudication, duration of steroid treatment prior to TAB, specimen length, bilateral TAB, and use of ultrasound/MRI (imaging) were recorded for meta-regression. RESULTS: One hundred and thirteen articles met eligibility criteria. The I 2 was 92%, and with such high heterogeneity, meta-analysis is unsuitable. The median yield of TAB was 0.25 (95% confidence interval 0.21 to 0.27), with interquartile range 0.17 to 0.34. On univariate meta-regression age (coefficient 0.012, p = 0.025) was the only statistically significant patient factor associated with TAB yield. CONCLUSIONS: Systematic review revealed high heterogeneity in the yield of TAB. The median utility rate of 25% and its interquartile range provides a benchmark for decisions regarding the under/overutilization of TAB and aids in the evaluation of non-invasive alternatives for the investigation of GCA.

Ptosis Repair in Ocular Myasthenia Gravis.

Ptosis repair was performed in patients with ocular myasthenia gravis by a posterior approach (Fasanella-Servat, 12 eyelids of nine patients) or levator advancement (eight eyelids of five patients) techniques. There were eight males and five females. Median age was 73 years and range 30-86 years. The median duration of myasthenia was 10 years and range 2 to 28 years. Pyridostigmine and prednisone were widely used prior to surgical referral, but ineffective or intolerable in all. The mean preoperative upper margin-reflex distance (MRD) was 0.55 mm (range -1 to 2 mm). The levator excursion range was 10 to 16 mm and mean 12.4 mm. Mean follow-up was 9.1 months. Postoperatively, the MRD ranged from 0.5 to 4 mm, with a mean of 2.3 mm. Two patients had lagophthalmos postoperatively (one posterior approach, one levator advancement) that did not require correction. Three of five patients who underwent levator advancement required repeat ptosis repair.
