Long-duration spaceflight missions (including the International Space Station [ISS]) are in one of the most remote and harsh environments humans live and work in. Medical emergencies in space are even more complicated in an already high-risk environment. Despite training, ISS crewmembers face many challenges in diagnosing and managing disease with limited diagnostic capability and equipment on the ISS, restricted medication availability, delayed access to medical professionals; and the latency of space missions.

Intravitreal injections have revolutionized the treatment of retinal diseases, yet there are possible complications, such as noninfectious intraocular inflammation, a complication that may threaten vision and mimic infectious endophthalmitis. This review synthesizes current knowledge on inflammation after intravitreal therapy, with particular focus on sterile intraocular inflammation and retinal vasculitis associated with anti-VEGF agents such as brolucizumab and newer complement inhibitors like pegcetacoplan. The pathogenesis is multifactorial, involving patient-specific immune responses, drug-specific properties including aggregation or impurities, and deviations in preparation or delivery techniques.

Purpose: We sought to examine the demographic and clinical risk factors associated with specific mechanisms of open globe injuries (OGIs) and identify predictors of Zone III injuries across multiple tertiary eye care centers.

Patients And Methods: 1570 patients with OGIs presenting to the Wilmer Eye Institute, the Bascom Palmer Eye Institute, Massachusetts Eye and Ear, and Wills Eye Hospital between 2018-2021 were retrospectively reviewed. Multinomial and binomial logistic regression models were used to evaluate associations between demographic and clinical risk factors with injury mechanisms and Zone III injuries.

To perform an outcome-and-cost analysis of follow-up visits and associated imaging in patients presenting to the Massachusetts Eye and Ear (MEE) emergency department with commotio retinae. This retrospective consecutive case series comprised consecutive patients presenting to the emergency department from January 1, 2020, to January 1, 2022, who were diagnosed with contusion or other injuries of the eye or orbit (International Classification of Diseases, 10th edition, codes S05.1 and S05.

Purpose: Physician-to-physician electronic consultation (eConsults) are used across specialties; however, their effectiveness in ophthalmology has not been reported. This study evaluated the feasibility and diagnostic accuracy of a physician-to-physician ophthalmology eConsult program, assessed the timeliness of in-person evaluation, and characterized the clinical questions of non-ophthalmology providers.

Methods: Retrospective review of patients for whom an ophthalmology eConsult was placed to Massachusetts Eye and Ear from February 2019-August 2021.

The purpose of this study was to examine how demographics, etiology, and clinical examination findings are related to visual outcomes in subjects with open globe injury (OGI) across a large and generalizable sample. A retrospective cohort analysis was performed using data collected from the electronic medical records of four tertiary university centers for subjects with OGI presenting from 2018 to 2021. Demographic information, injury mechanisms, clinical exam findings, visual acuity (VA) at presentation and most recent follow-up were recorded.

Purpose: To assess and compare the rate of endophthalmitis and visual outcomes in cases of open globe injuries (OGIs) without intraocular foreign bodies repaired within and greater than 24 hours from the time of injury.

Design: A retrospective review of 2002 cases of OGIs presenting to a single institution.

Participants: Patients with OGIs were admitted and managed according to a standardized protocol.

Purpose Of Review: The growing push to integrate telemedicine into ophthalmic practices requires physicians to have a thorough understanding of ophthalmic telemedicine's applications, limitations, and recent advances in order to provide well tolerated and appropriate clinical care. This review aims to provide an overview of recent advancements in the use of ophthalmic telemedicine for anterior segment eye examinations.

Recent Findings: Virtual care for anterior segment evaluation relies on appropriate technology, novel workflows, and appropriate clinical case selection.

Purpose: To identify clinical characteristics of injured eyes associated with visual recovery in patients with open globe injuries (OGIs) and presenting with no light perception (NLP) vision.

Design: Retrospective chart review.

Subjects: All patients presenting to Massachusetts Eye and Ear with OGI and NLP vision from January 1999 to March 2022.

The standard of care for open globe injuries is prompt surgical closure, as delay in repair is a reported risk factor for post-traumatic endophthalmitis and is associated with worse visual outcomes. This article serves as a review of the current management and outcomes of open globe injuries repaired greater than 24 hours from the time of injury, specifically evaluating the rates of endophthalmitis in cases with and without intraocular foreign bodies, visual outcomes and rates of primary enucleation or evisceration.

Article Synopsis
  • Seven patients experienced serious eye injuries while trying to repair their garage doors due to a high-velocity spring dislodging.
  • These cases were treated at Massachusetts Eye and Ear from 2008 to 2023.
  • The patients' vision results varied significantly, ranging from 20/125 to no light perception, highlighting the dangers of DIY repairs without proper experience.

Traumatic inferior rectus muscle rupture secondary to blunt injury in the absence of associated orbital or ocular fractures or injury is rarely encountered, and there are limited published reports on subsequent surgical repair. We present the case of a 74-year-old man with complete inferior rectus transection following a fall with facial strike. A computed tomography scan of the face was unremarkable.

Background: Clinicians are increasingly adopting telemedicine in an effort to expand patient access and efficiently deliver care. The degree of health disparities among patients receiving otolaryngologic telemedical care is unclear.

Aims: We performed a retrospective cross-sectional study to explore disparities in telemedicine delivery.

 Ophthalmology residency programs aim to improve resident surgical teaching through increased surgical exposure over a 4-year period. Resident-centric surgical clinics across various surgical specialties have been established to help develop surgical autonomy and experience. We present the first demonstration of a resident-centric chalazion incision and drainage clinic (chalazion clinic) in an ophthalmology residency with the goal of increasing early surgical exposure to residents.

Purpose: Convention is to perform open globe injury (OGI) repair within 24 h to minimize risk of endophthalmitis. However, there are limited data assessing how time to operative repair (OR) within 24 h impacts postoperative visual acuity (VA).

Methods: Manual retrospective chart review of 633 eyes at Massachusetts Eye and Ear (MEE) with a diagnosis of OGI between 2012 and 2022.

Purpose: Open globe injuries (OGIs) are categorized by zone, with zone 3 (Z3) comprising wounds > 5 mm beyond the limbus. Outcomes of Z3 OGIs are highly heterogeneous. Open globe injuries with far posterior Z3 (pZ3) wounds were hypothesized to have worse visual and anatomic outcomes.
