ABSTRACT
PURPOSE: Thyroid eye disease (TED) is characterized by a variety of disfiguring periocular changes. Vertical globe changes affecting the relative position of the eyelids are not well understood in patients with TED. This study seeks to determine the effect of orbital decompression on vertical globe displacement in patients with TED, without TED, and with intraconal tumor (ICT). METHODS: For this cross-sectional study, a clinical database was used to identify patients with TED. Comparison groups were drawn from separate anonymized databases. Vertical position and interpupillary distance (IPD) were measured from photographs and exophthalmos was measured via Hertel's exophthalmometer. Primary outcomes were vertical globe position at baseline and postoperatively in patients with TED and ICT. Secondary outcomes included the relationship between vertical globe position, exophthalmos, and IPD. RESULTS: Among 269 participants meeting the inclusion criteria, mean vertical globe position was significantly lower in patients with TED following lateral decompression surgery compared to controls, after accounting for race, age, and sex. While patients with ICT had a significant difference in preoperative and postoperative IPD, patients with TED did not. Medial or inferior decompression did not significantly change globe position and lateral decompression did not cause lateral canthal dystopia in patients with TED. No association between postoperative changes in exophthalmometry, IPD, and globe position was found in patients with TED. CONCLUSIONS: Patients with TED experience hypoglobus that does not improve following decompression surgery. There was no correlation between change in vertical globe position and exophthalmos or IPD among patients with TED. Surgeons should discuss the possibility of hypoglobus as a persistent finding for patients with TED undergoing decompression surgery.

PURPOSE: To describe an artificial intelligence platform that detects thyroid eye disease (TED). DESIGN: Development of a deep learning model. METHODS: 1944 photographs from a clinical database were used to train a deep learning model. 344 additional images ('test set') were used to calculate performance metrics. Receiver operating characteristic, precision-recall curves and heatmaps were generated. From the test set, 50 images were randomly selected ('survey set') and used to compare model performance with ophthalmologist performance. 222 images obtained from a separate clinical database were used to assess model recall and to quantitate model performance with respect to disease stage and grade. RESULTS: The model achieved test set accuracy of 89.2%, specificity 86.9%, recall 93.4%, precision 79.7% and an F1 score of 86.0%. Heatmaps demonstrated that the model identified pixels corresponding to clinical features of TED. On the survey set, the ensemble model achieved accuracy, specificity, recall, precision and F1 score of 86%, 84%, 89%, 77% and 82%, respectively. 27 ophthalmologists achieved mean performance of 75%, 82%, 63%, 72% and 66%, respectively. On the second test set, the model achieved recall of 91.9%, with higher recall for moderate to severe (98.2%, n=55) and active disease (98.3%, n=60), as compared with mild (86.8%, n=68) or stable disease (85.7%, n=63). CONCLUSIONS: The deep learning classifier is a novel approach to identify TED and is a first step in the development of tools to improve diagnostic accuracy and lower barriers to specialist evaluation.
ABSTRACT
PURPOSE: To report a novel case of dark without pressure in a patient with a choroidal osteoma. To our knowledge, this association has not been previously reported. METHODS: Observational case report. Review of clinical examination and multi-modal imaging findings in a patient with a choroidal osteoma and dark without pressure. RESULTS: A 21-year-old African American woman with no significant past medical history presented with a large, unilateral, juxtapapillary, subretinal, orange-colored, ovoid-shaped lesion with macular involvement. An overlying area of mottled pigmentary changes, fibrosis, and atrophy were present. Adjacent to and surrounding the osteoma was an annular band of hyperpigmented mid-peripheral retina with a sharply demarcated scalloped border that abruptly changed to normal-appearing peripheral retina. Multi-modal imaging including wide-field fluorescein angiography, optical coherence tomography, and ophthalmic B-scan were performed. The funduscopic and imaging findings were consistent with a diagnosis of choroidal osteoma and dark without pressure. CONCLUSION: The examination and imaging findings in this patient suggest a unique association between two relatively uncommon lesions, choroidal osteoma, and dark without pressure. Although these two lesions may simply be coinciding in the same eye, there may be an association with space-occupying lesions causing a change in photoreceptor structure.

The authors present a case of an eyelid eccrine porocarcinoma, a very rare malignant sweat gland tumor characterized histopathologically by nests of atypical poromatous cells and the presence of duct-like lumina. Histopathologic analysis of this case also exhibited numerous loose tumor cells in the adjacent tear film, a finding that has not been previously described.

Ocular complaints represent up to 3% of all emergency department (ED) visits. These presentations can result in permanent vision loss if not promptly diagnosed and treated. Recently, point of care ultrasound (POCUS) has been investigated for the evaluation of ocular pathology in the ED. Multiple studies have investigated the role that ultrasound may play in the early diagnosis of these patients. Ocular ultrasound can be used to visualize the structures of the eye and evaluate for pathology such as retinal detachment, vitreous hemorrhage and vitreous detachment. This comprehensive review aims to present current evidence for the efficacy and reliability of ED ocular ultrasound use in the detection of retinal detachment and additional ocular pathologies.
