Validation of the Retinal Detachment after Open Globe Injury (RD-OGI) Score as an Effective Tool for Predicting Retinal Detachment

Diagnostic Accuracy of B-Scan Ultrasonography in Detecting Vitreoretinal Pathology after Open-Globe Injury

PURPOSE

To assess the diagnostic accuracy of B-scan ultrasonography (echography) after open-globe injury (OGI) repair in detecting vitreoretinal pathology, as confirmed by intraoperative inspection during subsequent pars plana vitrectomy (PPV).

DESIGN

Retrospective, single-center, consecutive case series.

PARTICIPANTS

Patients with OGI treated at the University of Iowa Hospitals and Clinics from February 2018 through December 2023 who underwent OGI repair and had at least 1 B-scan performed postrepair but before subsequent PPV.

METHODS

B-scans were performed by an experienced echographer and reviewed by the managing vitreoretinal surgeon for the presence of vitreous hemorrhage (VH), retinal tear (RT), retinal detachment (RD), choroidal detachment, and vitreoretinal incarceration. B-scan findings were compared with findings on direct inspection during PPV, which served as the gold standard.

MAIN OUTCOME MEASURES

Sensitivity, specificity, and positive/negative predictive value of B-scan findings.

RESULTS

The study included 62 eyes of 61 patients, predominantly with severe OGIs (mean presenting logarithm of the minimum angle of resolution visual acuity of 2.52 ± 0.41; 75% with an Ocular Trauma Score of 1 or 2). B-scan had excellent diagnostic accuracy for VH, but, for every other type of vitreoretinal pathology, there were significant false positives, false negatives, or both. B-scan sensitivity was particularly low for vitreoretinal incarceration (11%), RT (32%), and RD (78%).

CONCLUSIONS

This study identified much lower diagnostic accuracy of B-scan ultrasonography after OGI for all vitreoretinal pathologies except VH compared with previous, smaller studies that reported perfect accuracy (100% sensitivity and specificity). Ultrasonography provides useful clinical information but should not be solely relied upon to diagnose or rule out severe vitreoretinal pathology that may prompt vitreoretinal referral or PPV after OGI.

Instrumenting Carotid Sonography Biomarkers and Polygenic Risk Score As a Novel Screening Approach for Retinal Detachment

Purpose

Retinal detachment (RD) is a vision-threatening condition that manifests silently before abrupt disease onset; thus, most of the RD at-risk individuals are left unchecked until the first RD attack.

Methods

To establish an RD risk-informing system for a broader population, we utilized carotid ultrasonography (CUS) biometrics, RD polygenic risk score (PRSRD), and clinical covariates (COVs) to assess RD risk predisposition factors. First, a backpropagation logistic regression model identified RD-associated CUS biomarkers and further incorporated them as a multivariable RD-risk nomogram. Next, a PRSRD model was established with the selected single-nucleotide polymorphisms (SNPs) curated as high functional expression candidates in the retina single-cell RNA datasets. Finally, a three-component RD prediction model (CUS, PRSRD, and COVs) was assembled by logistic cumulative analysis.

Results

Demographic analysis reported hypertension (HTN) status was associated with RD (odds ratio [OR] = 1.601). The CUS regression model revealed that the minimum flow of the right internal carotid artery (ICA-Qmin; OR = 1.04) and the time-averaged maximum velocity of the right common carotid artery (CCA-TAMAX; OR = 1.03) were associated with increased RD risk. Notably, genome-wide association studies (GWAS) identified three significant SNPs (IGFBPL1 rs117248428, OR = 1.63; CELF2 rs56168975, OR = 1.72; and PAX6 rs11825821, OR = 1.61; P < 5.00 × 10-6) that are highly expressed at the RD border of the retinal pigment epithelium and choroid. Finally, the three-component model demonstrated state-of-the-art RD prediction (AUCHTN+ = 0.95, AUCHTN- = 0.93).

Conclusions

Based on instrumenting CUS images and genetic PRSRD, we are proposing a screening method for RD at-risk patients.

Translational Relevance

Results from this study demonstrated the combination of CUS and GWAS as a cost-effective, population-wide screening framework for identifying RD at-risk individuals.

Traumatic retinal detachment: A contemporary update

Retinal detachment following ocular trauma (TrRD) is one of the leading causes of blindness and visual impairment worldwide. In the absence of a standardized definition, the diagnosis of traumatic retinal detachment relies on identifying a history of trauma that precedes the detachment. There is an increasing pool of data regarding the etiology and epidemiology of TrRD.Various causes of TrRD mentioned in the literature include work-related eye trauma in construction and manufacturing industries, sports injuries, explosive eye injuries, road traffic accidents, and intraocular foreign bodies. Although there is extensive literature on post-trauma retinal detachments, a comprehensive discussion of its pathogenesis, management, outcomes, and complications is lacking. We offer an in-depth review of the epidemiology, risk factors, pathogenesis, diagnosis, management, and outcomes of TrRD based on the current literature.

Retinal Detachments after Open-Globe Injury: Risk Factors and Outcomes

PURPOSE

To identify risk factors for retinal detachment (RD) after open-globe injury (OGI) and evaluate outcomes of RD repair after OGI.

DESIGN

Case-control study.

PARTICIPANTS

Overall, 769 patients presented with 786 OGIs, which were surgically managed with ≥ 30 days of follow-up. Of the 786 eyes, 223 developed RD, the other 551 served as controls, and RD status of 12 eyes was unknown.

METHODS

A retrospective chart review was performed of all OGIs presented to the University of Michigan between 2000 and 2022. Multivariable regression identified risk factors for RD after OGI and predictors of poor vision after RD repair. Kaplan-Meier analysis estimated time from OGI to RD.

MAIN OUTCOME MEASURE

Predictors of visual outcome after RD repair after OGI.

RESULTS

After OGI, 223 (28.4%) of 786 eyes were diagnosed with RD, with > 73% diagnosed within a month. Predictors of RD include posterior injury (zone II vs. I odds ratio [OR], 1.60 [95% confidence interval {CI}, 1.04-2.46]; P = 0.0331; zone III vs. I OR, 2.29 [1.53-3.41]; P < 0.0001), vitreous hemorrhage (OR, 2.29 [1.54-3.1]; P < 0.0001), and presenting acuity worse than count fingers (CFs) (OR, 2.65 [1.69 - 4.16]; P < 0.0001). Retinal detachment repair took place in 142 of 223 eyes. The mean logarithm of minimal angle of resolution visual acuity (VA) improved from 2.3 ± 0.8 to 1.7 ± 0.9 after RD repair at 6-month follow-up, with 51.2% of eyes achieving CF or better vision. Single surgery anatomic success rate was 69.7% and final anatomic success was 88%. Predictors of vision worse than CF include history of ocular surgery (OR, 0.32 [0.11-0.94]; P = 0.039), proliferative vitreoretinopathy (PVR; OR, 0.39 [0.16 - 0.92]; P = 0.032), aphakia (OR, 0.25 [0.08 - 0.77]; P = 0.016), and redetachment (OR, 0.26 [0.1 - 0.63]; P = 0.003).

CONCLUSIONS

Most RD occur within the first month after OGI. Patients with posterior injuries, vitreous hemorrhage, or poor presenting VA were more likely to develop RD after OGI. Anatomic success was achieved in the majority, as was final VA of CF vision or better. History of ocular surgery, PVR at time of repair, aphakia, and redetachment were risk factors for a poor outcome.

Outcomes of Retinal Detachment after Open-Globe Injury, and Independent Validation of the Retinal Detachment after Open-Globe Injury Scoring System

PURPOSE

To independently validate the Retinal Detachment after Open-Globe Injury (RD-OGI) scoring system as a clinical prediction model for estimating the risk of retinal detachment (RD) after open-globe injury (OGI), and to characterize outcomes of RD stratified by RD-OGI risk category.

DESIGN

Retrospective, multi-institutional cohort study.

PARTICIPANTS

A validation cohort of 236 eyes with OGI managed at 2 academic institutions from 2017 through 2021 was compared with the predictions of the RD-OGI score model and to the derivation cohort of 893 eyes with OGI used to develop it.

METHODS

RD-OGI scores were calculated, and patients were stratified into 3 risk groups (low, moderate, and high). The incidence of RD in the validation cohort was used to calculate performance metrics to evaluate predictive accuracy of the RD-OGI score.

MAIN OUTCOME MEASURES

Area under the receiver operating characteristic curve (AUC), sensitivity, specificity, and accuracy of the RD-OGI score; anatomic success (retina attached or detached); and best-corrected visual acuity (BCVA) at last follow-up.

RESULTS

In the validation cohort, 92 of 236 eyes (39%) demonstrated RD after OGI. The RD incidence predicted by the RD-OGI score was correlated strongly with actual RD incidence in the validation cohort (Spearman ρ = 0.92; P < 0.001). The RD-OGI score demonstrated high discrimination with the validation cohort (AUC, 0.84; 95% confidence interval [CI], 0.79-0.89). An RD-OGI score of 2.5 was found to have 73% accuracy, 93% sensitivity, and 60% specificity for predicting no RD (RD-OGI score < 2.5) versus RD (RD-OGI score ≥ 2.5). Median BCVA at last follow-up for successfully reattached eyes was comparable for high-risk eyes (approximately 20/380) and moderate-risk eyes (approximately 20/300; P > 0.99), but both were significantly worse compared with low-risk eyes (approximately 20/25; P = 0.010).

CONCLUSIONS

The RD-OGI score reliably predicts the risk of developing RD after OGI. In eyes that develop RD, a higher RD-OGI score is correlated strongly with a greater risk for poor functional and anatomic outcomes. An RD-OGI score of 2.5 or more identifies eyes at substantial risk of RD and adverse outcomes and may serve as a useful cutoff for guiding referral to a vitreoretinal surgeon after primary globe closure.

Predictors of Long-term Ophthalmic Complications after Closed Globe Injuries Using the Intelligent Research in Sight (IRIS®) Registry

Purpose

To identify clinical factors associated with the need for future surgical intervention following closed globe ocular trauma.

Design

Retrospective cohort study.

Subjects Participants and/or Controls

Patients in the American Academy of Ophthalmology Intelligent Research in Sight (IRIS®) Registry with a diagnosis of closed globe ocular trauma occurring between 2013 and 2019, identified using International Classification of Disease, 10th Revision and Systematized Nomenclature of Medicine codes.

Methods

Diagnosis codes were used to identify multiple concomitant diagnoses present on the date of closed globe ocular trauma. Survival analyses were performed for each outcome of interest, and linear regression was used to identify clinical factors associated with the risk of surgical intervention.

Main Outcome Measures

Outcomes included retinal break treatment, retinal detachment (RD) repair, retinal break treatment or RD repair, glaucoma surgery, and cataract surgery.

Results

Of the 206 807 patients with closed globe ocular trauma, 9648 underwent surgical intervention during the follow-up period (mean, 444 days): 1697 (0.8%) had RD repair, 1658 (0.8%) had retinal break treatment, 600 (0.3%) had glaucoma surgery, and 5693 (2.8%) had cataract surgery. Traumatic cataract was the strongest risk factor for cataract surgery (hazard ratio, 13.0; 95% confidence interval, 10.8-15.6), traumatic hyphema showed highest risk for glaucoma surgery (7.24; 4.60-11.4), and vitreous hemorrhage was the strongest risk factor for retinal break treatment and detachment repair (11.01; 9.18-13.2 and 14.2; 11.5-17.6, respectively) during the first 60 days after trauma date. Vitreous hemorrhage was a risk factor for cataract surgery at > 60 days after trauma date only. Iris-angle injury was the strongest risk factor for glaucoma surgery > 60 days after trauma, while vitreous hemorrhage remained the strongest factor for retinal break treatment and detachment repair at > 60 days. Traumatic hyphema was a risk factor for all surgical outcomes during all follow-up intervals.

Conclusions

Diagnosis of concomitant traumatic cataract, vitreous hemorrhage, traumatic hyphema, and other risk factors may increase the likelihood of requiring surgical intervention after closed globe ocular trauma.

Outcomes and Prognostic Factors Following Pars Plana Vitrectomy for Intraocular Foreign Bodies-11-Year Retrospective Analysis in a Tertiary Care Center

Aim: To evaluate the visual outcome of penetrating ocular injuries with a retained intraocular foreign body (IOFB) managed by pars plana vitrectomy (PPV) and to describe the risk factors associated with poor visual acuity and retinal detachment (RD) development. Methods: Medical records of 56 patients with IOFB that were removed by PPV over a period of 11 years (1 January 2010−31 December 2020) were reviewed. We extracted the demographic data, initial and final best corrected visual acuity (BCVA) using standard Snellen chart, IOFB characteristics, complications and surgical details. Outcome was evaluated according to the final BCVA: poor <0.1, good 0.1−<0.5 or excellent ≥0.5. Results: The mean age was 36.1 ± 14.1 (range, 16−71) years and the majority of patients were males (55 out of 56, 98.2%). IOFB was retinal in 27 (48.2%) cases and intravitreal in 29 cases (51.8%). IOFB size was ≤3mm in 26 (46.4%) cases and >3mm in 30 (53.6%) cases. Preoperative RD was identified in 12 (21.4%) cases and endophthalmitis in 17 cases (30.4%). IOFBs larger than 3 mm and retinal location were associated with RD development. Poor visual outcome was associated with initial BCVA, retinal location, RD and endophthalmitis. Conclusion: Initial BCVA, retinal foreign body, RD and endophthalmitis were risk factors for poor visual outcome.

The artificial iris - Analysis of various implantation techniques after ocular trauma

Purpose

The aim of this study is to analyze the outcome of various techniques for a custom-made iris prosthesis implantation as part of reconstructive anterior segment surgery following traumatic aniridia.

Methods

This retrospective interventional study was done for 6 eyes that received an artificial iris as secondary reconstructive measure for photophobia and unsatisfactory vision following initial globe repair. Different implantation techniques were employed. These included simple sulcus implantation, implantation of a composite (iris prosthesis with attached intraocular lens) implant, and combinations with phacoemulsification, vitrectomy, and penetrating keratoplasty.

Results

In all cases, the artificial iris was implanted successfully. In the follow-up period (1-48 months), postoperative complications included rhegmatogenous retinal detachment, prolonged intraocular inflammation, and corneal transplant decompensation due to graft rejection. There was no case of secondary glaucoma. Complications could be managed successfully. All patients showed improved best-corrected visual acuity and were satisfied with functional and cosmetic results.

Conclusion

This case series highlights the different implantation techniques for reconstruction of the anterior segment after ocular trauma. The versatility of the custom-made iris implant accounts for a wide range of applications and the foldable material reduces the need for large incisions in the already traumatized eye.

Reliability of the ocular trauma score for the predictability of traumatic and post-traumatic retinal detachment after open globe injury

AIM

To elucidate the question of whether the ocular trauma score (OTS) and the zones of injury could be used as a predictive model of traumatic and post traumatic retinal detachment (RD) in patients with open globe injury (OGI).

METHODS

A retrospective observational chart analysis of OGI patients was performed. The collected variables consisted of age, date, gender, time of injury, time until repair, mechanism of injury, zone of injury, injury associated vitreous hemorrhage, trauma associated RD, post traumatic RD, aphakia at injury, periocular trauma and OTS in cases of OGI.

RESULTS

Totally 102 patients with traumatic OGI with a minimum of 12mo follow-up and a median age at of 48.6y (range: 3-104y) were identified. Final best corrected visual acuity (BCVA) was independent from the time of repair, yet a statistically significant difference was present between the final BCVA and the zone of injury. Severe trauma presenting with an OTS score I (P<0.0001) or II (P<0.0001) revealed a significantly worse BCVA at last follow up when compared to the cohort with an OTS score >III. OGI associated RD was observed in 36/102 patients (35.3%), whereas post traumatic RD (defined as RD following 14d after OGI) occurred in 37 patients (36.3%). OGI associated RD did not correlate with the OTS and the zone of injury (P=0.193), yet post traumatic RD correlated significantly with zone III injuries (P=0.013).

CONCLUSION

The study shows a significant association between lower OTS score and zone III injury with lower final BCVA and a higher number of surgeries, but only zone III could be significantly associated with a higher rate of RD.

Factors Associated with Visual Outcome after Primary Repair of Open-Globe Injury by Ophthalmology Residents in Training in a Tertiary Eye Center

Purpose

To assess factors associated with visual outcome after open-globe injury (OGI) repair by trainees.

Methods

In this observational study, charts of OGIs repaired by trainees at King Chulalongkorn Memorial Hospital, Chulalongkorn University, Bangkok were retrospectively reviewed. Preoperative, intraoperative, and postoperative outcomes (day 1, month 1, and month 6 postoperation) were analyzed.

Results

A total of 78 OGIs presented in a 10-year period. A biphasic pattern was found among the young and the elderly. Approximately 73.6% of the cases had had surgical repair outside office hours. A majority of cases had been caused by machinery and hammers, and had visual acuity (VA) <20/200. Three cases were reported as having been unsuccessful intraoperatively for globe repair. A fifth of the cases required evisceration/enucleation within 2 weeks of presentation. Presenting VA worse than hand motion was associated with the risk of evisceration/enucleation (OR 14.5, P=0.013). VA improved at 6 months postoperation to the range of counting fingers and 20/200 (OR 15.6, P<0.01). High ocular trauma scores (OTSs) was associated with lower risk of evisceration/enucleation, and 12% retinal detachment (RD) was discovered, of which 90% occurred within 1 month after OGI repair.

Conclusion

Most OGIs were efficiently managed by the trainees, seldomly requiring assistance from subspecialists. Poor initial VA was associated with high risk of visual loss, whereas higher OTSs were inversely related to lower risk of evisceration or enucleation. There was a higher percentage of participants with final VA of 20/100-20/20 than the preoperative period. Precaution and careful evaluation of RD in the early postoperative period is recommended.

The epidemiology and outcomes of combat ocular trauma among local nationals managed at a deployed military hospital in Afghanistan

BACKGROUND/OBJECTIVES

There is limited published data on combat ocular trauma (COT) among local nationals managed at deployed United States (US) and United Kingdom (UK) military hospitals in recent conflicts. We report the epidemiology and outcomes of COT from a deployed military hospital in Afghanistan.

SUBJECTS/METHODS

In this retrospective case series, consecutive injuries requiring ophthalmic surgery at a military hospital in Afghanistan where the sole US and UK ophthalmologist(s) were deployed between January 2017 and September 2019 were reviewed. The main outcomes were mean post-operative visual acuity (VA) in open and closed globe injury and the incidence of retinal detachment after open globe repair.

RESULTS

There were 102 eyes of 84 patients who had ocular injuries and underwent ophthalmic surgery at the military hospital. Most patients were male (81 [96%]) and were local nationals (71 [85%]). Blast exposure (82 [80%]) was the most common mechanism of injury. Mean post-operative VA was 1.24 ± 2.29 logMAR (20/348 Snellen equivalent) in open globe injury and 1.59 ± 1.17 logMAR (20/778 Snellen equivalent) in closed globe injury. After open globe repair, retinal detachment developed in 8 of 18 (44%) eyes.

CONCLUSIONS

COT injuries often resulted in poor post-operative VA and retinal detachment after open globe repair was common. The high incidence and severity of COT sustained by local civilians and combatants in this study may support programs to increase the availability and wear of combat eye protection among local nationals partnered with US and coalition troops.

Wood-Related Open-Globe Injuries

Purpose:

This work evaluates the clinical characteristics, visual outcomes, and complications of patients treated for open-globe injuries (OGIs) caused by wooden objects.

Methods:

A retrospective review of medical records was conducted on patients presenting to a tertiary trauma center with an OGI between January 2005 and December 2017. Medical records were isolated for wounds caused by wooden objects. Patient demographics were recorded, with presenting visual acuity (VA), physical examination findings, and wound characteristics. After primary globe repair, secondary complications, need for additional surgery, and visual outcomes were noted until final examination. Main outcome measures were final VA and secondary complications. The Ocular Trauma Score (OTS) was computed and assessed for clinical relevance related to visual outcomes.

Results:

Thirty-two patients met the inclusion criteria, with 15 (47%) being injured by plant material. Thirty of the patients were men (94%). A large portion of patients presented with hand motion or worse vision (48%), and there were high rates of hyphema (59%), vitreous hemorrhage (31%), retinal detachment (28%), and endophthalmitis (9%). Two patients eventually required enucleation. At last follow-up, 19 patients achieved 20/100 VA or better (59.4%), which correlated with their OTS ( P < .001).

Conclusions:

Despite the high clinical severity of wood OGIs, the potential for visual recovery remains high. The OTS appropriately assesses the severity of injuries and the likely prognosis in this cohort of patients.

Open Globe Injury with Intraocular Foreign Body

Purpose

To investigate characteristics of Open Globe Injuries (OGI) that presented with Intra-Ocular Foreign Body (IOFB), along with their long-term visual outcomes, complications and need for subsequent surgeries.

Methods

Retrospective interventional consecutive case series of OGIs with IOFBs that presented to the Eye Trauma service at the Massachusetts Eye and Ear from 2010 to 2015. Data collected included time from injury to OGI repair, location of injury and IOFB, retinal detachment (RD) rate, presenting and final visual acuity (VA) and subsequent surgeries.

Results

Fifty-seven consecutive cases of OGIs with IOFBs were included. The majority of patients were male (93%), mean age was 37 years and mean follow-up was 28 +/- 22 months. The median time from injury to OGI repair was 0 days (range: 0-16 days). Overall, 38/57 (66.7%) eyes achieved final vision of 20/40 or better and 43/57 (75.4%) vision of 20/150 or better. Zone I injuries were the most common (86%), followed by Zone II (16%), and Zone III (10%). 33 cases had IOFBs in the anterior segment only and 24 cases had posterior segment involvement. In total, 30% of cases (17/57) were complicated by an RD, 58.3% (14/24) in the posterior versus 9.1% (3/33) in the anterior IOFB group.( p<0.01). There were no cases of endophthalmitis. Posterior IOFB and higher zone of injury were found to be risk factors for RD both at presentation (all p<0.05) and post-primary repair.(all p<0.05) Posterior IOFB was associated with higher vitrectomy rates both at presentation (p<0.0001) and post-primary repair (p=0.002) and worse long-term visual outcome (p = 0.014).

Conclusion

OGIs with IOFB involving the posterior segment are associated with higher complication and re-operation rates and worse visual prognosis compared to those involving the anterior segment only.

Contextual Assessment of Retinal Injuries - Tasks of the Ophthalmological Expert

The ophthalmologic assessment of causal relationships is subject to formal guidelines, depending on the legal field (social law in the statutory accident insurance, civil law in the private accident insurance). After determining all objective and subjective findings of the individual case with complete recording of the medical facts, the ophthalmologist has the task of making a summarizing assessment of the existing cause-and-effect relationship. With regard to the distinction between retinal damage caused by an accident or retinal disease not caused by an accident, it is necessary to weigh up the natural causality according to the state of medical experience on the basis of the criteria strength of association, consistency, specificity, temporal sequence, dose dependence, agreement with previous findings, experimental reliability and analogous consideration. All records of medical findings from the patient's medical history and the individual description of the accident must be included in the expert opinion. In the case of several competing causes (often accident and pre-existing damage), the social law in the statutory accident insurance must present the causal contributions with roughly estimated probabilities. In civil law, valid for the private accident insurance, the existence of partial causality (approx. 25, 50, 75%) must be evaluated.

Thomas A. Swift's Electric Rifle Injuries to the Eye and Ocular Adnexa: The Management of Complex Trauma

PURPOSE

To report the ocular and adnexal injuries sustained by patients with Thomas A. Swift's electric rifles (TASER; TASER International, Scottsdale, AZ), review the literature, and discuss the management of this complex trauma.

DESIGN

Multicenter, retrospective case series and literature review.

PARTICIPANTS

Seventeen eyes of 16 patients (5 eyes of 5 patients treated at 3 institutions, and 12 eyes of 11 previously reported cases).

METHODS

The clinical data of 17 eyes were pooled. Spearman's correlation coefficient was used to assess the association between the extent of TASER injury and patient outcomes.

MAIN OUTCOME MEASURES

Extent of TASER injury (zone of injury, penetrating vs. perforating) and association with patient outcomes (visual acuity [VA] and retinal detachment [RD]).

RESULTS

In our cohort, 4 patients were transported by law enforcement and 1 was transferred from a community hospital. Four patients were taken to the operating room for TASER removal and globe repair; 1 patient underwent removal in the emergency room. Of 17 pooled cases, 12 (71%) involved open-globe injury. Of these, there was a high rate of zone 3 injuries (100%; n = 12) and a high incidence of RD (73%; 8 of 11, eviscerated eye excluded). Among patients with closed-globe injury (n = 5), 1 patient demonstrated exudative RD and 1 patient demonstrated retinal dialysis with RD. Of 10 patients with RD, 1 (10%) achieved resolution with monitoring (exudative RD); 1 (10%) underwent cryopexy and pneumatic retinopexy; 3 (30%) underwent vitrectomy, and 5 (50%) with poor prognosis did not undergo vitreoretinal surgery. In the 3 patients who underwent vitrectomy, all 3 (100%) demonstrated redetachment resulting from proliferative vitreoretinopathy and required additional surgery. Visual acuity on presentation was significantly correlated with final VA (ρ = 0.783; P = 0.02). Men (94%) were more likely than women (6%) to sustain TASER trauma. Median age was 26 years. There was a 50% rate of loss to follow-up.

CONCLUSIONS

Thomas A. Swift's electric rifle injuries to the eyes or ocular adnexa represent complex trauma. Zone 3 injuries are common. The visual prognosis is guarded, and eyes may require multiple surgeries to preserve vision. Patients are at high risk for loss to follow-up by way of incarceration.
