Abstract
AIMS To characterize the clinical features of ocular trauma resulting from lawn mower, identify determinants of unfavorable final visual acuity (FVA), and assess the spectrum of microbial in posttraumatic endophthalmitis. METHODS This retrospective study enrolled patients who experienced ocular trauma due to lawn mower at Zhongshan Ophthalmic Center from January 2013 to August 2021. Demographics, clinical features, isolated microorganisms, risk factors influencing reduced visual acuity, treatment regimens, and utilization of eyewear were collected. RESULTS The study included 140 participants (140 eyes) (49.47 ± 12.03 years, 95% male). The predominant injury manifestations were penetrating globe injuries (75.7%) and intraocular foreign bodies (51.4%). Endophthalmitis occurred in 35 cases (25%) and Bacillus cereus (23.5%) was the primary pathogen, followed by Staphylococcus epidermidis (11.8%) and Streptococcus species (11.8%). Following the initial assessment, where 77.9% of patients had initial visual acuity (IVA) at grade IV (ranging from light perception to 4/200) and only 0.7% attained grade I (better than 20/40), post-treatment results revealed that 5.7% achieved FVA at grade I, with a concurrent decrease in patients with grade IV vision to 64.3%. Multivariate logistic regression revealed that injury protection (p < 0.001, OR = 0.237, 95% CI = 0.126-0.446), IVA (p = 0.001, OR = 4.102, 95% CI = 1.730-9.729), and retinal detachment (p = 0.042, OR = 8.105, 95% CI = 1.075-61.111) were significant independent risk factors impacting FVA. CONCLUSION Lawn mower often cause severe ocular injuries, with high-velocity metal foreign bodies that can lead to infections, most commonly caused by Bacillus cereus. Correct use of protective gear, initial vision assessment, and detecting retinal detachment are crucial for visual prognosis.

Sharifi M, Sedaghat M, Vaseie M. Ocular injuries sustained at home in five metropolitan cities: a review of 5008 cases. MEDICAL HYPOTHESIS, DISCOVERY & INNOVATION OPHTHALMOLOGY JOURNAL 2024; 12:194-202. [PMID: 38601050 PMCID: PMC11002462 DOI: 10.51329/mehdiophthal1486] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 10/10/2023] [Accepted: 01/20/2024] [Indexed: 04/12/2024]
Abstract
Background In Iran, ocular injuries sustained at home are a growing public health issue, and few studies have explored their prevalence and the frequencies of different causes of these injuries. We investigated the features of ocular injuries at home among children and adolescents (aged < 18 years), adults (18 - 64 years), and the elderly ( ≥ 65 years) in five metropolitan cities. Methods In this cross-sectional study, we recruited individuals with ocular injuries sustained at home who presented to 12 public/teaching hospitals in five metropolitan cities during a 5-month period. Using clinical records within the emergency department archives, we collected the following data: age, sex, frequency of injuries requiring hospital admission or surgical intervention, and causes of eye injuries, documented as 1) cleaning products, 2) chemical products, 3) kitchen items, 4) cooking activities, 5) toys, 6) falls from height, 7) sports equipment, 8) penetrating or cutting, 9) abrasions, 10) foreign bodies, and 11) direct blows by other individuals. Results Of 5008 participants from the five cities, 74% (n = 3711) were male and 26% (n = 1297) were female. The most frequent causes of injury among children and adolescents, adults, and the elderly were toys, kitchen items, and cooking activities, respectively. In children and adolescents, injuries were caused by kitchen items, toys, foreign bodies, and direct blows by other individuals more frequently than in adults or the elderly, and by cleaning products and abrasions more frequently than in the elderly (all P < 0.05). In adults, injuries were caused by cleaning products, cooking activities, falls from height, sports equipment, penetrating or cutting, and abrasions more frequently than in children and adolescents or the elderly (all P < 0.05), and by kitchen items, toys, and blows by other individuals more frequently than in the elderly (all P < 0.05). In the elderly, injuries were caused by chemical products more frequently than in children and adolescents or adults, and by cooking activities, falls from height, and sports equipment more frequently than in children and adolescents (all P < 0.05). In adults, the frequency of ocular injuries was significantly higher in Tehran and lower in Mashhad when comparing each with that of the other four cities (all P < 0.05). We found a significantly higher frequency of ocular injuries by cleaning and chemical products in Tehran, by toys in Shiraz, by falls from height in Isfahan, and by direct blows by other individuals in Ahvaz when comparing each to that of the other four cities (all P < 0.05). Regarding the prevalence of severe ocular injuries among the children/adolescent and adult age groups, conditions were relatively better in Shiraz and relatively unfavorable in Mashhad. Conclusions Ocular trauma was more common in male individuals and the younger age groups. Approximately half of the causes were kitchen items, toys, and foreign bodies, which are avoidable by enhancing public eye health awareness. The prevalence of severe ocular injuries in individuals aged < 18 years was high, highlighting the necessity of nationwide preventive strategies for pediatric ocular injuries.

Explosive eye injuries: characteristics, traumatic mechanisms, and prognostic factors for poor visual outcomes. Mil Med Res 2023; 10:3. [PMID: 36631894 PMCID: PMC9835351 DOI: 10.1186/s40779-022-00438-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/11/2022] [Accepted: 12/21/2022] [Indexed: 01/13/2023] Open
Abstract
BACKGROUND Explosions can produce blast waves, high-speed medium, thermal radiation, and chemical spatter, leading to complex and compound eye injuries. However, few studies have comprehensively investigated the clinical features of different eye injury types or possible risk factors for poor prognosis. METHODS We retrospectively reviewed all consecutive records of explosive eye injuries (1449 eyes in 1115 inpatients) in 14 tertiary referral hospitals in China over 12 years (between January 2008 and December 2019). Data on demographics, eye injury types, ocular findings, treatments, and factors affecting visual prognosis were extracted from a standardized database of eye injuries and statistically analyzed. RESULTS Mechanical ocular trauma accounted for 94.00% of explosion-related eye injuries, among which intraocular foreign bodies (IOFBs) resulted in 55.17% of open globe injuries (OGIs) and contusion caused 60.22% of close globe injuries (CGIs). Proliferative vitreous retinopathy (PVR) was more common in perforating (47.06%) and IOFB (26.84%) than in penetrating (8.79%) injuries, and more common with laceration (24.25%) than rupture (9.22%, P < 0.01). However, no difference was observed between rupture and contusion. Ultimately, 9.59% of eyes were removed and the final vision was ≤ 4/200 in 45.82% of patients. Poor presenting vision [odds ratio (OR) = 5.789], full-thickness laceration of the eyeball ≥ 5 mm (OR = 3.665), vitreous hemorrhage (OR = 3.474), IOFB (OR = 3.510), non-mechanical eye injury (NMEI, OR = 2.622, P < 0.001), rupture (OR = 2.362), traumatic optic neuropathy (OR = 2.102), retinal detachment (RD, OR = 2.033), endophthalmitis (OR = 3.281, P < 0.01), contusion (OR = 1.679), ciliary body detachment (OR = 6.592), zone III OGI (OR = 1.940), and PVR (OR = 1.615, P < 0.05) were significant negative predictors for poor visual outcomes. CONCLUSIONS Explosion ocular trauma has complex mechanisms, with multiple eyes involved and poor prognosis. In lethal level I explosion injuries, eyeball rupture is a serious condition, whereas contusion is more likely to improve. In level II injuries, IOFBs are more harmful than penetrating injuries, and level IV represents burn-related eye injuries. PVR is more associated with penetrating mechanisms than with OGI. Identifying the risk predictors for visual prognosis can guide clinicians in the evaluation and treatment of ocular blast injuries.

Bacterial isolates, their antimicrobial susceptibility pattern, and associated factors of external ocular infections among patients attending eye clinic at Debre Markos Comprehensive Specialized Hospital, Northwest Ethiopia. PLoS One 2022; 17:e0277230. [PMID: 36327266 PMCID: PMC9632921 DOI: 10.1371/journal.pone.0277230] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2022] [Accepted: 10/22/2022] [Indexed: 11/06/2022] Open
Abstract
Background External eye infection caused by bacteria can lead to reduced vision and blindness. Therefore, pathogen isolation and antimicrobial susceptibility testing are vital for the prevention and control of ocular diseases. Objective The main aim of this study was to assess bacterial isolates, their antimicrobial susceptibility pattern, and associated factors of external ocular infection (EOI) among patients attended eye clinic at Debre Markos Comprehensive Specialized Hospital (DMCSH), Northwest Ethiopia. Methods We conducted a cross-sectional study in patients with external ocular infections from January 1, 2021, to June 30, 2021, at DMCSH. Socio-demographic and clinical data were collected using semi-structured questionnaires. Following standard protocols, external ocular swabs were collected and inoculated onto blood agar, chocolate agar, MacConkey agar and mannitol salt agar (MSA). Finally, bacterial isolates were identified by Gram stain, colony morphology, and biochemical tests. Antimicrobial susceptibility testing was done by using the modified Kirby-Bauer disk diffusion technique according to Clinical and Laboratory Standards Institute (CLSI) guideline. Cleaned and coded data were entered into EpiData version 4.2 software and exported to Statistical Packages for Social Sciences (SPSS) version 22 for analysis. Bivariate logistic regression was applied to investigate the association between predictors and outcome variables. P-values ≤ 0.05 with 95% confidence interval were considered statistically significant. Results Two hundred seven study participants were enrolled in this study. More than half of them (57.5%, 119/207) were males, and 37.7% (78/207) of them were ≥ 65 years old. A total of 130 (62.8%) bacterial isolates were identified, with Gram-positive bacteria accounting for 78.5% (102/130) of the isolates. Staphylococcus aureus was the most common isolate with a 46.2% (60/130) prevalence. Ciprofloxacin was comparatively effective against Gram-positive and Gram-negative bacteria. The prevalence of culture-confirmed bacteria was significantly associated with age groups 15–24 (AOR: 9.18, 95%CI: 1.01–82.80; P = 0.049) and 25–64 (AOR: 7.47, 95%CI: 1.06–52.31; P = 0.043). Being farmer (AOR: 5.33, 95% CI: 1.04–37.33; P = 0.045), previous history of eye surgery (AOR: 5.39, 95% CI: 1.66–17.48; P = 0.005), less frequency of face washing (AOR: 5.32, 95% CI: 1.31–7.23; P = 0.010) and face washing once a day (AOR: 3.07, 95% CI: 1.13–25.13; P = 0.035) were also significantly associated with the prevalence of culture-confirmed bacteria. Conclusion The prevalence of culture-confirmed bacteria among patients with EOI was high in the study area. A considerable proportion of bacterial isolates exhibited mono and/or multi-drug resistance. Age (15–64 years), being farmer, previous history of eye surgery and less frequency of face washing were significantly associated with the prevalence of culture-confirmed bacteria. Bacterial isolation and antibiotic susceptibility testing should be routinely performed in the study area to combat the emergence of antibiotic resistance.

Abstract
Severe mechanical ocular trauma with no light perception (NLP) predicts a poor prognosis of visual acuity and enucleation of the eyeball. Since the innovative treatment concept of exploratory vitreoretinal surgery has developed and treatment technology has advanced, the outcomes of severe ocular trauma treatment in NLP patients have greatly improved. However, there remains a lack of unified standards for the determination, surgical indication, and timing of vitrectomy in NLP eye treatment. To address these problems, we aimed to create evidence-based medical guidelines for the diagnosis, treatment, and prognosis of mechanical ocular trauma with NLP. Sixteen relevant recommendations for mechanical ocular trauma with NLP were obtained, and a consensus was reached. Each recommendation was explained in detail to guide the treatment of mechanical ocular trauma associated with NLP.

Abstract
Purpose: To examine the epidemiologic and clinical characteristics of ocular injuries and their association with socioeconomic status (SES).Material and Methods: All cases of ocular injuries hospitalized in Department of Ophthalmology of University Clinical Center Tuzla, Bosnia and Herzegovina, from January 2009 to December 2012 and January 2017 and December 2019 were prospectively followed. The injuries were classified according to Ocular Trauma Classification System (OTCS) and Birmingham Eye Trauma Terminology (BETT).Results: This study included a total of 420 eyes from 396 patients. There were 162 (38.57%; 95%CI: 32.86-44.99) open globe injuries (OGI) and 258 (61.43%; 95%CI: 54.16-69.4) closed globe injuries (CGI). The decrease in incidence of ocular trauma requiring hospitalization was noted from 16.7 per 100 000 (95%CI: 13.11-20.97) in 2009 to 9.25 per 100 000 (95%CI: 6.64-12.55) in 2019 (p=0.006). Most injuries occurred in males 341 (81.19%; 95%CI: 72.8-90.28), active working patients 258 (61.43%, 95%CI:54.16-69.4), and patients with rural residence 285 (67.86%; 95%CI: 60.21-76.21). Almost all ocular injuries 418 (99.52%; 95%CI: 90.21-109.54) occurred in patients with middle and lower SES categories, and home was the most prevalent place of injury in 258 (61.43%, 95%CI: 54.16-69.4) patients. The total of 289 (70.49%; 95%CI: 62.59-79.1) patients had good final best corrected visual acuity (BCVA). Poor final BCVA was associated with lower ocular trauma score (OTS) (p=0.000), poor initial BCVA (p=0.000), penetrating injuries of cornea (p=0.004) and sclera (p=0.001), Zone III injuries (p=0.000), intraocular foreign body presence (p=0.000), cataract (p=0.002), retinal detachment (p=0.001), endophthalmitis (p=0.000) and vitreous hemorrhage (p=0.010).Conclusion: This study provides a detailed insight into epidemiology and socio-economic characteristics of patients hospitalized for ocular injuries.
