Purpose: Self-inflicted facial gunshots (SIGSWs) typically result in a spectrum of severe injuries to facial structures, including the orbit and globe. Roughly three-quarters of those who arrive to the hospital will survive their injuries, and recidivism is typically low. Therefore, effective management is paramount to preserve vision, and long-term quality of life. The objective of this study is to characterize the common injuries to the orbit, globe, and periocular structures following SIGSWs,...

Purpose: Although it is a commonly held belief that stretching of the optic nerve is important in dysthyroid optic neuropathy (DON), it is probably mainly due to microvascular ischemia arising from high pressure at the orbital apex. If stretch is important in DON, one would expect longer optic nerves and reduced optic nerve compliance in these patients. Methods: Retrospective comparative case series for 75 patients with DON, and for age- and sex-matched control patients with thyroid eye disease...

Purpose: To retrospectively describe the clinical characteristics, management, and outcomes of a series of patients with solitary fibrous tumor (SFT) of the orbit and to evaluate signal transducer and activator of transcription 6 (STAT6) as a diagnostic marker. Methods: Review of a retrospective, noncomparative, consecutive series of patients treated at a single institution with a histopathologic diagnosis of SFT. Demographic, clinical, and imaging data were collected, and paraffin-embedded...

Here, the authors present the first case, to the best of the authors' knowledge, of bilateral lacrimal puncta agenesis in a patient with KS.#8232;The proband patient was a 29-year-old woman diagnosed with this syndrome, brought to our office due to recurrent conjunctivitis where agenesia of lacrimal puncta was observed. Therapeutic options were exposed but, as the concomitant...

Purpose: To analyze and quantify the characteristics and parameters of the eyelid and adnexa of males and females and correlate these findings to an aesthetically pleasing score. Methods: This is an Institutional Review Board approved study involving healthy male and female volunteers. The margin-to-reflex distance, palpebral fissure, inferior scleral show, tarsal platform show, and brow fat span were measured using Image J digital photographic analysis and the images were scored by 110 non-ophthalmologists....

A 37-year-old male was found to have a firm yellowy-white palpable mass embedded within the conjunctival surface of the tarsal plate of the left upper eyelid. This was asymptomatic and noted on a routine examination for contralateral epiphora. An excisional biopsy was performed and a “rock-like nodule” was removed with histopathology confirming the presence of mature bone. While the literature describes these lesions located in other aspects of the orbit, this is the first described case of an epibulbar...

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.

Purpose: To evaluate the ability of preoperative phenylephrine testing to predict postoperative upper eyelid tarsal platform show in patients undergoing Müller muscle–conjunctival resection (MMCR) ptosis repair without concurrent blepharoplasty. Methods: A retrospective chart review was performed on 52 eyelids of patients who underwent MMCR without external skin incision. Photographs were reviewed to objectively and subjectively compare the results of phenylephrine testing to postoperative...

Basal cell carcinoma accounts for 90% of malignant tumors of the eyelid. Basal cell carcinoma has been reported to rarely occur in conjunction with osteoma cutis or bone formation in the skin. The mechanism of this secondary osteoma cutis has yet to be explained. Herein, the authors present the case of a 68-year-old woman with a rapidly enlarging basal cell carcinoma with secondary osteoma cutis of the left lower eyelid.

Purpose: To determine whether thyroid eye disease (TED) is associated with a change in temporal fossa soft tissue volume. Methods: CT imaging studies were selected from patients with TED considering orbital decompression surgery and from an age-matched group of controls presenting to the Emergency Department for nontraumatic conditions requiring CT imaging. Measurements of the temporal fossa fat pad and soft tissue thickness were used as a proxy for volume and were performed using the zygomaticotemporal...

Purpose: To demonstrate the utility of an ultrasonic aspirator (Sonopet, Stryker Corporation; Kalamazoo, MI) for debulking firm, soft tissue masses of the orbit. Methods: Case series. The ultrasonic aspirator was used to debulk firm, soft tissue masses in 3 cases. The initial patient had a large orbitofacial mass extending to the inferior and lateral orbital apex secondary to IgG4 disease. The second patient had a lacrimal sac adenocarcinoma extending to the medial orbital apex. The third...

Proptosis is a common yet cardinal symptom that may indicate the development of a wide range of diseases. Causes of proptosis are usually classified into vascular, inflammatory, endocrine, and neoplastic. Herein, the authors describe a case where proptosis manifested as the primary and only symptom of a massive brain arteriovenous malformation. Deprived of any other conventional symptoms and signs of a brain arteriovenous malformation, such as headaches, nausea, vision loss, increased ocular pressure,...

When NASA mathematician Katherine Johnson retired in 1986, she’d spent three-plus decades at the agency and only seen a handful of American women go into space. One, of course, was Sally Ride in 1983; the second was Judith Resnik, who died in the Space Shuttle Challenger disaster. But it wasn’t for a lack of potential. “Girls are capable of doing everything men are capable of doing,” Johnson said in an interview years later. “Sometimes they have more imagination than men.”Though Johnson knew this...

Annie Jump Cannon joined the Harvard Observatory in 1896 to help build the official classification system for stars. Her calculations were largely drawn off the atmospheric refraction in telescopic photos rather than in situ observations; she and her fellow female colleagues earned about half of the men in their positions. The university didn't designate Cannon as an astronomer until near the end of her career in 1938. (Smithsonian Institution/)Mary Golda Ross led an entire life before turning her...

Not even the ocean's deepest dwellers are immune to climate change. (NOAA/)The fish that live at the bottom of the sea are a hardy bunch. They’re adapted to handle crushing pressure, little to no sunlight, and a meager supply of food. But these otherwise gritty fish are also very sensitive to changes in the climate of the water around them, a new study suggests.Scientists surveyed different patches of seafloor in the Gulf of California and saw that variations in temperature and oxygen levels had...

The incorporation of digital health technologies (DHT) has gained significant traction within healthcare organizations as it promises to support patients and healthcare professionals to optimize the provision of care and self-management in a personalized manner, particularly in chronic diseases. Yet, recent systematic reviews have found there is no significant evidence demonstrating that Digital Health improves the management of chronic diseases such as chronic obstructive pulmonary disease (COPD).1...

Chronic Respiratory Disease, Volume 17, Issue , January-December 2020. Recent studies have suggested that an increased peripheral monocyte count predicts a poor outcome in fibrosing interstitial lung disease (ILD). However, the association between an increased monocyte count and acute exacerbations (AEs) of fibrosing ILD remains to be elucidated. Our retrospective cohort study aimed to assess the impact of peripheral monocyte count on AEs of fibrosing ILD. We analyzed the electronic medical records...
