Article Synopsis
  • This study evaluated the effects of LASIK, PRK, and SMILE surgeries on patient-reported outcomes among active-duty U.S. Military Servicemembers, focusing on vision quality and satisfaction before and after surgery.
  • A total of 375 Servicemembers underwent these procedures, with results showing that 94-95% achieved 20/20 vision or better, with significant improvements in far vision for LASIK and PRK specifically.
  • Overall, all three surgical options provided excellent visual outcomes and minimal side effects, enhancing daily activities for the Servicemembers six months post-operation.

Background: Obstetric triage is usually undertaken by a midwife and involves conducting a physical assessment to identify a woman's presenting problem. The Birmingham Symptom-specific Obstetric Triage System (BSOTS) was developed in the United Kingdom (UK) to overcome challenges associated with triaging women by standardising the maternity triage process. The Australian study site is the first hospital outside the UK to implement this approach.

Background And Objective: The goal of this study was to determine the anatomic outcome of traumatic retinal detachment (RD) from combat ocular trauma.

Materials And Methods: Retrospective study of patients sustaining a traumatic RD in Operation Iraqi Freedom and Operation Enduring Freedom who were evacuated to Walter Reed Army Medical Center from 2001 to 2011. The Fisher exact test, Wilcoxon rank sum test, and Agresti and Coull methods were used for analyses.

Introduction: Traumatic brain injury (TBI) remains a significant source of disability for active duty service members in both deployed and training settings as well as those who have left active service. Service members with ocular trauma are at risk for a TBI and should be screened appropriately. Early detection results in treatment to minimize long-term sequelae which can often be debilitating.

Background/purpose: To characterize the nature of posterior segment ocular injuries in combat trauma.

Methods: Eyes in the Walter Reed Ocular Trauma Database were evaluated for the presence of posterior segment injury. Final visual outcomes in open-globe versus closed-globe injuries and by zone of injury and the types of posterior segment injuries in open-globe versus closed-globe injuries were assessed.

Purpose: To determine the rates and types of open-globe wounds in soldiers admitted to Walter Reed Army Medical Center from 2001 to 2011 after sustaining combat injuries.

Methods: Data were collected in the Walter Reed Ocular Trauma Database. Inclusion criteria were patients who suffered open-globe injuries.

Lipids in complex, protein-enriched films at air/liquid interfaces reduce surface tension. In the absence of this benefit, the light refracting and immunoprotective tear film on eyes would collapse. Premature collapse, coupled with chronic inflammation compromising visual acuity, is a hallmark of dry eye disease affecting 7 to 10% of individuals worldwide.

Purpose: To update the epidemiology of ocular injuries in soldiers admitted to Walter Reed Army Medical Center (WRAMC) from 2001 to 2011 after sustaining combat injuries in Operation Iraqi Freedom (OIF) and Operation Enduring Freedom (OEF).

Methods: Data were collected in the Walter Reed Ocular Trauma Database. A Bayesian Network Analysis was completed to better understand the relationships between different ocular demographic variables, injuries, surgeries, ocular trauma scores (OTS) and visual outcomes.

Purpose: To assess whether densitometry analysis appropriately monitors the development of haze in myopic patients after photorefractive keratectomy (PRK) when compared to subjective slit-lamp haze grade examinations, and whether sutureless cryo-preserved amniotic membrane reduced postoperative haze development when compared to the standard bandage contact lens.

Methods: In this retrospective cohort at the Center for Refractive Surgery, Walter Reed National Military Medical Center, a secondary analysis of prospectively collected data was performed. In the prospective study, participants underwent PRK for myopia.

Purpose: To assess the visual outcomes of small-incision lenticule extraction (SMILE) after the first year of treatments at a military refractive surgery center and compare with photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK) outcomes during the same period.

Setting: Warfighter Refractive Eye Surgery Program and Research Center, Fort Belvoir, VA.

Design: Retrospective study.

Background: To analyze the final visual acuity (VA) of neuro-ophthalmologic injuries (NOI) in combat ocular trauma and to study the association of NOI with systemic neurologic injury (SNI) and traumatic brain injury (TBI).

Methods: The Walter Reed Ocular Trauma Database was reviewed. Inclusion criteria were any US service member and Department of Defense civilians who suffered NOI, SNI, or TBI in Operation Iraqi Freedom or Operation Enduring Freedom.

Background: This study evaluated the VIsion PERformance (VIPER) simulator's ability to assess the functional visual performance in warfighters conducting civilian and military tasks.

Methods: Thirty service members, aged 25-35 years old with a best corrected distance visual acuity (VA) better than or equal to 20/20 or logarithm of the minimum angle of resolution (logMAR) 0.00, were randomized to locate and identify road signs and mock improvised explosive devices (IEDs) under either daytime conditions or with infrared imagery, with (cc) and without (sc) wearing their habitual correction.

Introduction: The goal of this study is to update the incidence of hyphema in Operation Iraqi (OIF) and Enduring Freedom (OEF). We wanted to assess associated ocular injuries and final visual acuity (VA) in open-globe versus closed-globe injuries with a hyphema.

Materials And Methods: We performed a retrospective review of the Walter Reed Ocular Trauma Database (WRTOD) to identify U.

Article Synopsis
  • The study examines the demographics and clinical outcomes of patients who underwent eye removal surgeries (enucleation or evisceration) due to combat-related injuries during Operations Iraqi Freedom and Enduring Freedom from 2001 to 2011.
  • A total of 109 surgeries were performed on 890 injured eyes, with the majority resulting from injuries caused by improvised explosive devices; the most common surgical location was a combat support hospital.
  • The findings highlight a significant need for these surgeries in combat situations and emphasize the lack of research on the psychosocial effects experienced by veterans undergoing such procedures.
