RESUMO
PURPOSE: To evaluate the difference between target and actual refraction after phacoemulsification and intraocular lens implantation at an academic teaching institution's Comprehensive Ophthalmology Service. DESIGN: Retrospective study. PARTICIPANTS: We examined 1275 eye surgeries for this study. METHODS: All consecutive cataract surgeries were included if they were performed by an attending or resident surgeon from January through December 2010. Postoperative refractions were compared with preoperative target refractions. Patients were excluded if they did not have a preoperative target refraction documented or if they did not have a recorded postoperative manifest refraction within 90 days. MAIN OUTCOME MEASURES: The main outcome measure was percentage of cases achieving a postoperative spherical equivalent ± 1.0 diopter (D) of target spherical equivalent. RESULTS: We performed 1368 cataract surgeries from January through December of 2010. Of these, 1275 (93%) had sufficient information for analysis. Of the included cases, 94% (1196 of 1275) achieved ± 1.0 D of target refraction by 90 days after cataract surgery. CONCLUSIONS: This paper establishes a new benchmark for a teaching hospital, where 94% of patients achieved within 1.0 D of target refraction after cataract surgery. The refractive outcomes after cataract surgery at this academic teaching institution were higher than average international benchmarks.

PURPOSE: To report the ocular injuries sustained by survivors of the April 15, 2013, Boston Marathon bombing and the April 17, 2013, fertilizer plant explosion in West, Texas. DESIGN: Multicenter, cross-sectional, retrospective, comparative case series. PARTICIPANTS: Seventy-two eyes of 36 patients treated at 12 institutions were included in the study. METHODS: Ocular and systemic trauma data were collected from medical records. MAIN OUTCOME MEASURES: Types and severity of ocular and systemic trauma and associations with mechanisms of injury. RESULTS: In the Boston cohort, 164 of 264 casualties were transported to level 1 trauma centers, and 22 (13.4%) required ophthalmology consultations. In the West cohort, 218 of 263 total casualties were transported to participating centers, of which 14 (6.4%) required ophthalmology consultations. Boston had significantly shorter mean distances to treating facilities (1.6 miles vs. 53.6 miles; P = 0.004). Overall, rigid eye shields were more likely not to have been provided than to have been provided on the scene (P<0.001). Isolated upper body and facial wounds were more common in West largely because of shattered windows (75.0% vs. 13.6%; P = 0.001), resulting in more open-globe injuries (42.9% vs. 4.5%; P = 0.008). Patients in Boston sustained more lower extremity injuries because of the ground-level bomb. Overall, 27.8% of consultations were called from emergency rooms, whereas the rest occurred afterward. Challenges in logistics and communications were identified. CONCLUSIONS: Ocular injuries are common and potentially blinding in mass-casualty incidents. Systemic and ocular polytrauma is the rule in terrorism, whereas isolated ocular injuries are more common in other calamities. Key lessons learned included educating the public to stay away from windows during disasters, promoting use of rigid eye shields by first responders, the importance of reliable communications, deepening the ophthalmology call algorithm, the significance of visual incapacitation resulting from loss of spectacles, improving the rate of early detection of ocular injuries in emergency departments, and integrating ophthalmology services into trauma teams as well as maintaining a voice in hospital-wide and community-based disaster planning.

PURPOSE: To determine whether formal ophthalmology evaluation is necessary after operative repair of orbital fractures and the association of an ocular injury to the severity of facial injury. PATIENTS AND METHODS: This was a retrospective cohort study of patients with orbital fractures undergoing operative repair from 2005 to 2013. Subjects were included if they had undergone reconstruction of orbital floor fractures and had data from pre- and postoperative examinations by the oral and maxillofacial surgery and ophthalmology services available. The predictor variables included the service performing the ocular examination (oral and maxillofacial surgery or ophthalmology) and the number of fractures present. The outcome variables were the presence of pre- and postoperative ocular injuries. Logistic regression models were used to determine the relationship of the fracture number to ocular injury. RESULTS: A total of 28 subjects had undergone repair of orbital fractures with preoperative and postoperative examinations performed by both services. Preoperative ocular injuries were found in 17 of the 28 subjects. Those detected by oral and maxillofacial surgeons were limited to changes in visual acuity, pupillary response, and extraocular muscle dysfunction in 11 subjects. Two subjects had new postoperative ocular findings that were considered minor and did not alter management. An increasing number of facial fractures was associated with an increased risk of ocular trauma. Those with 3 or more fractures had an odds ratio of 14.625 (95% confidence interval, 2.191 to 97.612, P = .006) for the presence of ocular injury. CONCLUSIONS: Operative repair of orbital fractures did not lead to new ocular injuries that would change the management. Thus, those without preoperative ocular injuries will not require a formal postoperative ophthalmology examination. However, the subjects with more fractures had an increased likelihood of ocular injuries.

Purpose Emergency medicine is a common access point to health care; disparities in this care by demographic characteristics, including race and ethnicity, may affect outcomes. The Massachusetts Eye and Ear (MEE) Emergency Department (ED) is a subspecialty emergency department; data from this site can be utilized to better understand social determinants of quality ophthalmic care. Design This is a retrospective cross sectional cohort study in the MEE ED examining patient visits from June 1, 2016 to June 30, 2019. Methods Using the electronic medical record system, all unique visits were identified between June 1, 2016 and June 30, 2019 (inclusive); patient demographics (sex, race, ethnicity [Hispanic vs. non-Hispanic], primary care provider [PCP] status, insurance type, zip code, primary language), date of visit, triage category and outcomes (final diagnosis, visit duration, and next visit at MEE within 3 months of the ED visit) were collected. Kaplan-Meier plots were used to visualize likelihood of follow-up visit to MEE for urgent patients based on demographics. Multivariate linear regression was used to examine factors affecting visit durations, as stratified by urgency, and Cox proportional hazards regression was used to establish hazard ratios for next visit to MEE. Results Of the 46,248 ophthalmology ED initial visits, only triage status, season of visit, out-of-state residency, Medicare coverage, and Medicaid coverage led to statistically significant differences in visit durations for urgent visits compared with the respective reference groups. Similar trends persisted within the non-urgent visit cohort for visit durations. Residency, insurance coverage, season of visit, race, PCP status, and sex were identified as statistically significant predictors of the likelihood of a follow-up visit. Conclusion Data from an ophthalmic emergency department suggest that demographic factors do impact patient visit duration and time to follow-up visit. These findings suggest a continued need for attention to social determinants of health and equitable care of patients within ophthalmology.
RESUMO
PURPOSE: To examine the incidence and initial presentation of sports-related ocular injury in youth. METHODS: This retrospective case series study was performed at Massachusetts Eye and Ear, Boston, Massachusetts. Inclusion criteria were visit dates between January 1, 2010 and December 31, 2015, age 5 to 25 years, an ocular injury International Classifcation of Disease code, and a sports-related mechanism of injury. RESULTS: The final sample was 223 patients, representing approximately 20% of all youth eye injuries (mean age: 16.2 years (range: 6 to 24 years); 78.9% boys, 21.2% girls). The most common diagnosis was hyphema (72.2%). Most injuries occurred with soccer (23.3%), baseball (17.0%), and basketball (11.7%), with a mean visual acuity of 20/40, 20/50, and 20/50, respectively. The injuries with the lowest mean visual acuity resulted from paintball (20/500) and airsoft gun shooting (20/200). Thirty-three patients (14.7%) required surgical intervention. The average number of follow-up visits within 1 year was five. CONCLUSIONS: Approximately 20% of youth ocular injury visits were sports related, with male teenagers affected most. Hyphema was the most common type of sports-related eye injury posing a lifelong risk of ocular complications. Popular youth sports such as soccer, baseball, and basketball caused the most eye injuries. Shooting sports with paintball and airsoft guns were associated with the greatest loss of vision. Patients infrequently reported the use of protective eyewear at the time of injury. Protective eye equipment should be worn by youth participating in sports to prevent ocular trauma and the potential for surgical intervention. [J Pediatr Ophthalmol Strabismus. 2021;58(6):377-384.].

Importance: Orbital fractures are common in ocular trauma, and there is a need to develop predictive tools to estimate risk of concurrent ocular injury. Objective: To identify clinical and radiographic features that are associated with increased risk of substantial ocular injury in the setting of orbital fracture. Design, Setting, and Participants: Retrospective consecutive case series of patients who sustained orbital fractures between 2012 and 2018. Examinations were done at 1 of 2 level 1 trauma centers in the emergency or inpatient setting. A total of 430 consecutive patients (500 eyes) between 2012 and 2017 met inclusion criteria for the training sample. After building a predictive model, 88 additional consecutive patients (97 eyes) between 2017 and 2018 who met inclusion criteria were collected as a test sample. Main Outcomes and Measures: The primary outcome measure was substantial ocular injury distinct from orbital fracture. Results: The mean age of our patient population was 53.5 years (range, 16-100 years). The overall rate of substantial ocular injury was 20.4%, and the rate of injury requiring immediate ophthalmic attention was 14.4%. Five variables were found to be associated with increased risk of substantial ocular injury: blunt trauma with a foreign object (odds ratio [OR], 19.4; 95% CI, 6.3-64.1; P < .001), inability to count fingers (OR, 10.1; 95% CI, 2.8-41.1; P = .002), roof fracture (OR, 9.1; 95% CI, 2.8-30.0; P = .002), diplopia on primary gaze (OR, 6.7; 95% CI, 1.7-25.1; P = .003), and conjunctival hemorrhage or chemosis (OR, 4.2; 95% CI, 2.2-8.5; P < .001). The results were translated into a bedside tool that was tested in an independent group of eyes (n = 97) and found to be associated with substantial ocular injury with a 95% sensitivity (95% CI, 77.2-99.9), 40% specificity (95% CI, 28.9-52.0), 31.8% positive predictive value (95% CI, 27.5-36.5), and 96.8% negative predictive value (95% CI, 81.3-99.5). Conclusions and Relevance: A minority of patients with an orbital fracture had a substantial ocular injury. Certain radiographic and clinical findings were associated with substantial ocular injury. Testing of the algorithm in prospective longitudinal settings appears warranted.

PURPOSE: During the COVID-19 pandemic, there is growing concern that patients are forgoing necessary care. Emergency departments (ED) represent an important site of eye care. We analyzed patterns of ED visits at an eye-specific ED since the declaration of the public health crisis. MATERIALS AND METHODS: In this retrospective, cross-sectional single center study, medical records of 6744 patients who presented to the Massachusetts Eye and Ear ED between March 1st and April 30th in 2018, 2019, and 2020 were studied. The primary outcome measures were total volume of ED visits, proportion of urgent ED visits, and proportion of surgical visits. RESULTS: Overall, the median number of daily visits to the ED decreased by 18 visits per day since the declaration of public health guidelines (interquartile range, 9-24, p < 0.001). This accounted for a 32% decrease in the total volume of ED visits in 2020 compared to prior years during the study period (p < 0.001). There was a 9% increase in the proportion of primary diagnoses considered urgent (p = 0.002). The proportion of visits requiring urgent surgery increased by 39% (p = 0.004). CONCLUSION: The total number of eye-specific ED visits dropped compared to prior years while the proportion of urgent visits increased. Patients were likely more reluctant to seek eye care, deferring less urgent evaluation.
RESUMO
OBJECTIVES: To evaluate the impact of a comprehensive cataract surgery curriculum on the incidence of intraoperative complications. DESIGN: We retrospectively compared the total number of cataract surgeries that the residents performed in all of the teaching sites, and the incidences of intraoperative complications (anterior capsule tear, posterior capsule rent, vitreous loss, anterior vitrectomy, zonular dialysis, iris trauma, hemorrhage, dropped lens fragment, corneal wound burn, incorrect intraocular lens) for the surgeries performed at Massachusetts Eye & Ear by residents in the pre-intervention group (residents graduating in 2004 and 2005), before the implementation of a surgical curriculum, and the residents in the post-intervention group (residents graduating in 2014 and 2015). SETTING: Ophthalmology residency program at a major academic institution. PARTICIPANTS: Residents graduating in 2004, 2005, 2014, and 2015. RESULTS: We reviewed 4373 charts. 2086 of those surgeries were performed at Massachusetts Eye & Ear. The incidence of posterior capsule rent/vitreous loss/anterior vitrectomy was lower in the post-intervention group (1.4% versus 7.7%, p < 0.0001). Other complications were also lower in the post-intervention group. CONCLUSIONS: Implementation of a comprehensive cataract surgery curriculum focusing on pre-operative, intra-operative and post-operative interventions, with an emphasis on patient outcomes resulted in a decrease in the rate of intraoperative complications.

PURPOSE: Fingernail-induced corneal abrasions are one of the most common eye injuries that present to the emergency department, and yet there is little literature available to offer guidelines for management. We analyzed the treatment used in cases of fingernail-induced corneal abrasions that presented to the Massachusetts Eye and Ear Infirmary Emergency Department and studied its relationship to the development of complications such as recurrent erosion syndrome and infection. METHODS: We performed a retrospective review of 99 patients who presented to the Massachusetts Eye and Ear Infirmary Emergency Department with fingernail-induced corneal abrasions between January 1, 2009 and December 31, 2009. We followed the patients for 12 months and documented demographics, nature of the injury, treatment, and complications. RESULTS: The average age was 29.4 (range, 2-89) years. Forty-four percent (n = 44) were female and 56% (n = 55) were male. Of the 99 subjects, 39 had a full 12 month follow-up, and 7 developed a complication from the injury. Compared with the 32 subjects without complications, there was no difference in age or gender. However, there was a significant difference in that adults scratched by another adult were more highly represented in the group with complications (43%, n = 3/7 vs. 3%, n = 1/32; P = 0.0017). There was no significant difference in outcome by treatment used. CONCLUSIONS: This is the largest fingernail-induced corneal abrasion study completed to date. Patients are at risk of developing complications, but there is scant evidenced-based literature available for treating this common injury. Prospective trials should be performed to better optimize and standardize treatments.
