Influence of alcohol consumption on incidence and severity of open-globe eye injuries in adults

High risk and low prevalence diseases: Open globe injury

INTRODUCTION

Open globe injury (OGI) is a rare but serious condition that carries with it a high rate of morbidity.

OBJECTIVE

This review highlights the pearls and pitfalls of OGI, including presentation, diagnosis, and management in the emergency department (ED) based on current evidence.

DISCUSSION

OGI refers to full-thickness injury to the layers of the eye. OGI can be caused by blunt or sharp trauma, and subtypes include penetration, perforation, intraocular foreign body (IOFB), globe rupture, or mixed types. OGI is more common in males and usually secondary to work-related injury, but in women it is most commonly associated with falls. Emergency clinicians should first assess for and manage other critical, life-threatening injuries. Following this assessment, a thorough eye examination is necessary. Computed tomography (CT) may suggest the disease, but it cannot definitively exclude the diagnosis. While point-of-care ultrasound (POCUS) is highly sensitive and specific for some findings in OGI, its use is controversial due to potential globe content extrusion. Management includes protecting the affected eye from further injury, preventing Valsalva maneuvers that could extrude ocular contents, updating tetanus vaccination status, administering broad-spectrum antibiotics, and ophthalmology consultation for surgical intervention to prevent the sequelae of blindness and endophthalmitis.

CONCLUSION

An understanding of OGI can assist emergency clinicians in diagnosing and managing this sight-threatening traumatic process.

Clinical characteristics and visual outcomes of work-related open globe injuries in Japanese patients

Purpose: To investigate the clinical characteristics and visual outcomes of patients with work-related open globe injuries (OGIs) and compare them with patients with non-work-related OGIs. Design: Retrospective, observational, multicentre, case-control study. Methods: A total of 374 patients with work-related OGIs and 170 patients with non-work-related OGIs who presented to hospitals that belong to the Japan-Clinical Research of Study group from 2005 to 2015 were included in this study. Clinical data including age, sex, initial and final visual acuity, type of open globe injury, lens status, zone of injury, wound length, and presence of proliferative vitreoretinopathy, retinal detachment, expulsive haemorrhage, and endophthalmitis were recorded. Main Outcome Measures: Visual acuity. Results Work-related OGIs were associated with younger age, male sex, better initial and final visual acuity, more laceration, smaller wounds, presence of retinal detachment, and expulsive haemorrhage, compared with non-work-related OGIs. Multiple regression analysis revealed that final visual acuity is significantly associated with initial visual acuity, wound length, and the presence of proliferative vitreoretinopathy in work-related OGIs. Conclusions: Work-related OGIs showed better visual outcomes than other OGIs. Initial visual acuity, wound length, and the presence of proliferative vitreoretinopathy are predictors of visual outcomes in patients with work-related OGIs.

Clinical characteristics and outcomes of fall-related open globe injuries in Japan

PURPOSE

To investigate the clinical characteristics and visual outcomes in patients with fall-related open globe injuries and to evaluate differences between fall-related and non-fall-related open globe injuries in Japan.

METHODS

A retrospective review of patients with open globe injury who presented to Japan-Clinical Research of Study (J-CREST) hospitals between 2005 and 2015 was enrolled. Clinical information including age, sex, initial visual acuity, final visual acuity, type of injury, status of the crystalline lens, zone of injury, wound length, presence of retinal detachment, proliferative vitreoretinopathy, expulsive hemorrhage, and endophthalmitis was recorded.

RESULTS

A total of 374 eyes were enrolled, of which 120 (32.1%) suffered from fall-related injury with average age of 73.7 ± 15.9 years (range, 11-101 years). A majority of patients were female (55.8%). Of 120 patients with fall-related injury, 109 (90.8%) presented with rupture and 11 (9.2%) with laceration. A multiple regression analysis revealed that final visual acuity was significantly associated with initial visual acuity (r = 0.99, P < 0.001). Compared to non-fall-related open globe injuries, fall-related open globe injuries were associated with elderly age, female sex, poorer initial and final visual acuity, rupture, absence of the lens, larger wound size, retinal detachment, expulsive hemorrhage, and absence of endophthalmitis (P < 0.01).

CONCLUSIONS

Fall-related open globe injuries were more frequent in elderly female and accompanied by larger wound lengths and severer ocular complications. Visual outcomes in patients with fall-related open globe injuries were related to initial visual acuity.

Open-globe injuries with motor vehicle accidents: a 12-year review

PURPOSE

To evaluate demographics, characteristics, and outcomes of open-globe injuries (OGIs) in motor vehicle accidents (MVAs).

METHODS

Retrospective chart review of patients with OGIs related to MVAs that presented to University Hospital, Newark, from 2000 to 2012.

RESULTS

Twenty-five patients were identified; the average age of the patients was 33.3 years old (range, 5-75). The majority of patients (64 %) were males. The 25 vehicles comprised 24 automobiles and one motorcycle. Ten patients (40 %) wore seatbelts, and five (20 %) did not wear seatbelts. The seatbelt status was not documented in the remaining cases. Ethanol was documented as a contributing factor in five of the accidents. In terms of open-globe classification, 15 OGIs (60 %) were ruptures, and five (20 %) were penetrating injuries; three (12 %) had intraocular foreign bodies. Ten eyes (40 %) had a final VA of 20/400 or worse. Fourteen eyes (56 %) achieved a final VA of 20/200 or better; seven eyes (28 %) achieved a final VA of 20/40 or better.

CONCLUSION

Fifty-six percent of eyes with an open-globe injury related to MVAs achieved a final VA of 20/200 or better in this series. No eyes developed endophthalmitis.

A 10-year review of assault-related open-globe injuries at an urban hospital

BACKGROUND

To describe the demographics and outcomes of assault-related open-globe injuries (OGI) at University Hospital (UH), Newark, New Jersey over a ten-year period.

METHODS

The medical records of all subjects presenting to a single university referral center with an OGI were retrospectively analyzed to identify prognostic factors for enucleation and final visual acuity (VA) of no light perception (NLP).

RESULTS

One hundred and forty-eight eyes of 147 patients presented to UH with assault-related OGI. Eighty-two percent of patients were male, and the mean age was 35.9 years. The anatomic site of the wound was zone 3 in the majority (54.1 %) of eyes. Most common type of injury noted was rupture (57.4 %), followed by penetrating injury (35.1 %). Mean initial presenting and final VA in LogMAR were 2.38 ± 0.12 and 2.18 ± 0.16 respectively. Initial Snellen VA was no light perception (NLP) in 57 eyes (38.5 %); four eyes had an initial VA of ≥ 20/40 (2.7 %). Final VA was NLP in 68 eyes (45.9 %) of which 46 were enucleated (31.1 %); 18 eyes (12.2 %) had a final VA of ≥ 20/40. Fifty eyes (33.8 %) underwent pars plana vitrectomy (PPV). Significant risk factors of final VA of NLP or enucleation included initial VA of NLP, perforating or rupture type of OGI, and zone 3 injury. Eyes that sustained penetrating injuries were less likely to have final VA of NLP or require enucleation.

CONCLUSIONS

Assault-related OGIs carry an extremely poor visual prognosis and a high rate of enucleations. Only eighteen eyes (12.2 %) recovered VA ≥ 20/40. We found initial VA of NLP and zone 3 injury to be significant predictors of final VA of NLP or undergoing enucleation. Penetrating injuries were less likely to have a final VA of NLP or an enucleation.

[Open-globe injuries and intraocular foreign bodies involving the posterior segment]

Open globe injuries involving the posterior segment remain a major cause of visual loss in young adults. They occur more frequently in male than in female populations. The majority is due to domestic accidents, since work-related injuries have been decreasing due to proper education and use of safety equipment. However, leisure-related open globe injuries are on the increase. Prompt recognition and treatment of open globe injuries are essential. At presentation, it is necessary to collect etiological data such as cause, nature, time and place of injury. Anti-tetanus immunization must be confirmed. The presenting visual acuity and clinical examination data must be recorded. The lesion type is classified in accordance with the Birmingham Eye Trauma Terminology. Ocular ultrasound or computed tomography is performed for patients suspected of having an intra- or periocular foreign body. Functional prognosis is negatively influenced by a posterior or large rupture, the presence of an intraocular foreign body, the presence of retinal lacerations or retinal detachment, or the occurrence of posttraumatic infectious endophthalmitis. Recent advances in microsurgical techniques such as pars plana vitrectomy and new visualization techniques may improve the anatomical and functional prognosis for these patients. However, postoperative proliferative vitreoretinopathy remains a major concern: it is responsible for a significant rate of secondary retinal detachment with negative consequences for visual prognosis.
