PURPOSEOcular trauma is one of the most common causes of acquired blindness in children. It measures about 8%-14% of total childhood injuries. This study aims to determine the epidemiological profile of ocular trauma in the pediatric age group attending a tertiary hospital in northern India.

METHODSA retrospective study was conducted in our hospital between June 2014 to July 2015 and all the children aged 0-16 years presenting with ocular trauma in eye outpatient department and emergency were enrolled in the study. Various epidemiological parameters like age, sex distribution, duration of presentation, mode of injury, type of injury and final visual outcome were analyzed.

RESULTSOf total 357 patients, 271 (76%) were below the age of 12 years; 41.1% of children with ocular trauma belonged to age group 2-6 years. The male to female ratio was 2.9:1. Out of total patients, 242 (67.8%) presented with closed globe injury. Among the closed globe injury, the history of fall was present in about 35% of children, followed by trauma while playing with bat/ball (15.7%) and finger nail trauma (13.2%). Among open globe injury, trauma with needle, knife, glass and pen were common causes. Home was the most common place of injury (47.8%), followed by streets (17.9%) and playground (14.9%).

CONCLUSIONChildren are vulnerable to ocular trauma and need more supervision. Sharp objects like needles, knives, household chemicals like acids should be out of reach of children.

PURPOSEOcular trauma is the third leading cause of hospitalization in ophthalmology patients, imposing direct and indirect physical and psychological costs on society. This study aims to investigate the status of ocular trauma in hospitalized patients in the industrialized city of Kashan in 2011.

METHODSThis cross-sectional descriptive applied study was conducted in 2012 on patients hospitalized for ocular trauma. Data, including age, gender, occupation, education, timing of admission following accident, location of accident, type of injury, damaging instrument, and type of trauma, were collected using a questionnaire designed by a trained nurse, and analyzed using SPSS-16 software by means of means ± standard deviation, frequency, and percentage for descriptive data and t-test, one-way analysis of variance, Chi-square and Fisher exact test for analysis at significance level of p < 0.05.

RESULTSIn total, 82 patients were hospitalized due to ocular traumas. The majority of patients were male (65 patients, 79.3%). Their mean age was (25.4 ± 21.4) years, with an age range of 20-40 years (30 patients, 36.6%). Hyphema was the most common injury (26 patients, 25.5%), home was the most frequent incident location (32 patients, 39%), and knife or other cutting tools were mostly responsible for injuries (18 patients, 21.9%). Patients were hospitalized for 1e6 days, and the average length of stay in hospital was 2.63 days. Frequency distribution of injuries based on whether or not ruptures differed significantly among different age groups.

CONCLUSIONThe majority of ocular trauma occurred in young males. Knife was the principle culprit for eye injuries, followed by vehicles. To reduce such incidents, it is recommended that people be trained to avoid high-risk behaviors when using knives and to better heed driving rules and regulations.

OBJECTIVETo determine the prevalence of ocular trauma and the proportion of blindness and visual impairment due to trauma in a rural population in northern China.

METHODSThe Handan Eye Study is a population-based cross-sectional study that surveyed 6830 Chinese people aged 30+ years from 13 randomly selected villages in Yongnian County, city of Handan, Hebei Province, in July, 2006. All participants underwent a standardized interview and extensive examinations. A structured questionnaire was used to collect information on ocular trauma.

RESULTSOf the 5837 participants who filled out the questionnaire, 124 subjects [2.1%; 95% confidence interval (CI), 1.8%-2.5%] reported a history of ocular trauma in either eye, including 19 (0.3%) persons reporting trauma in both eyes. Men were more likely to have an eye injury than women [odds ratio (OR), 3.3; 2.2-4.9]. In multiple logistic regression models, ocular trauma was significantly more frequent among normotensive participants when compared with hypertensive participants (hypertensive vs. normotensive: OR, 0.6; 0.4-0.9) and among participants who had a history of falls (OR, 2.4; 1.2-4.8). The proportion of unilateral visual impairment and unilateral blindness due to trauma were 10.5% (13 subjects) and 21.0% (26 subjects), respectively.

CONCLUSIONOur study reports the prevalence of severe ocular trauma among adults in rural China, revealing a high proportion of blindness and visual impairment due to trauma. These findings suggest the need for educational strategies to increase eye health awareness in this rural population with focus on providing at least appropriate first aid care to reduce blindness due to trauma.

OBJECTIVEConsidering the difficulty in classifying some cases with eye trauma by Birmingham Eye Trauma Terminology (BETT) in our epidemiological study, we introduce a new classification for epidemiological study of mechanical eye injuries based on BETT.

METHODSA retrospective investigation was carried out in 31 hospitals from January 2005 to December 2010. All medical records of inpatients with eye injuries were reviewed. A total of 10 718 patients (11 227 eyes) were diagnosed as mechanical eye injuries. All mechanical eye injuries were tried to be classified using BETT. While some eye injuries were difficult to categorize. We recorded the injury type and case number. A new classification based on BETT was also used for the same project.

RESULTSOf 10 718 patients (11 227 eyes) with mechanical eye injuries, the following cases cannot be classified by BETT: 1 488 patients (1 559 eyes) with merely orbital or ocular adnexa injury, 1 961 (2 054) globe injuries associated with orbital or ocular adnexa injury, 271 (284) ocular surface foreign body (OSFB) or ocular wall foreign body (OWFB), 77 (89) contusion, 9 (11) lamellar laceration associated with OSFB or OWFB, 29 (30) rupture associated with OSFB, OWFB or intraocular foreign body and 60 (62) lace- ration associated with OSFB or OWFB. While according to our new classification, all eye injuries can be categorized without any difficulty.

CONCLUSIONDifficulty in classifying some eye injuries in epidemiological study by BETT brings some trouble to our study, which can be solved by our new eye injury classification to some extent. It is hoped that other ophthalmologists present better ones to make the classification more perfect.

BACKGROUND: The development of the medicine and the rise in the expectation of living has led the Korea into an aging society and the senior population in the Korea continues to grow. The objective of this study is to investigate the clinical features of geriatric ocular trauma in in a regional emergency medical center. METHODS: We retrospectively reviewed the medical records of 163 eyes of 146 patients older than 65 with ocular trauma who visited Emergency Room of Dongguk University Gyeongju Hospital from March 1, 2007 to February 29, 2012. RESULTS: In all patients, the incidence of the geriatric ocular trauma in patients over 65 was 7.3% (146 patients). And it was found to be 2.4 times more common in males (103 patients, 70.5%) than it was in females (43 patients, 29.5%). The mean age of patients was 70.7 years. Geriatric ocular trauma occurred mostly in the summer and the most common place of occurrence was the streets. Traffic accidents were the most common reason (35 patients, 24%) and the most common form of ocular trauma was the corneal erosion (42 patients, 21.1%). CONCLUSION: Through this study we found out the characteristics and the tendency of geriatric ocular trauma. And these results can be helpful in the prevention of geriatric ocular trauma and the improvement on treatment of geriatric ocular trauma.

OBJECTIVETo investigate the epidemiological characteristics of eye injuries sustained by military personnel in Chinese army.

METHODSEleven military evacuation hospitals located in different regions were selected for this study. We reviewed all the medical records of eye injuries sustained by military personnel between January 2005 and December 2009. Patients'information was collected. All data were put into database and analyzed statistically.

RESULTSTotally there were 415 inpatients with eye injuries (442 eyes) and their mean age was 24.40 years. Eye injury accounts for 13.51% of all eye diseases in this study. From 2006 to 2009, the number of eye injury increased gradually. Among them, 175 (42.17%) were injured in leisure time, and 145 (34.94%) in working time. Twenty-two (5.30%) patients had an eye surgery or history of eye disease before injury. In all, 246 patients (59.28%) were sent to evacuation hospital within 24 hours and 64 (56.64%) underwent surgeries in 24 hours after injury. There were 389 patients (93.73%) hospitalized for 1 time. Visual acuities of 187 eyes (42.31%) were grade 1 (larger than or equal to 20/40) after injury. When discharge, 349 eyes (78.96%) obtained a visual acuity of grade 1.

CONCLUSIONEye injury has a very frequent incidence in Chinese army and much more attention should be paid to prevent it.

This study was conducted to evaluate the influence of alcohol consumption on the risk of ocular trauma. We retrospectively reviewed the medical records of 1,024 patients who visited emergency department and received ophthalmologic examination from January 1 to December 31, 2009. The patients were divided into 2 groups: those with ocular trauma (n = 494) and those without (n = 530); the influence of alcohol consumption was compared between these 2 groups. In the ocular trauma group, the association of the causes and types of ocular trauma with alcohol consumption was evaluated. One of 530 patients of no trauma group and 117 (23.7%) of 494 patients of trauma group were related with alcohol intake, and the difference was statistically significant (P < 0.001). Concerning the causes, physical assault was significantly more common in alcohol-associated injury (P < 0.001). Regarding the types of injury, orbital wall fracture and hyphema showed a significant association with alcohol consumption (P < 0.001). Older age and nighttime injury were significantly related to the increased risk of alcohol-associated ocular trauma (P = 0.018 and < 0.001, respectively). In conclusion, alcohol consumption significantly increases the risk of ocular trauma.

BACKGROUNDSympathetic ophthalmia (SO), a rare, bilateral, diffuse granulomatous uveitis, usually occurs after open globe injury or intraocular surgery. We sought to identify the risk factors for the development of SO after open globe injury and describe their demographic and clinical features and outcomes of treatments.

METHODSA retrospective study of inpatients with globe injury in 15 tertiary referral hospitals of China from January 2001 to December 2005 was conducted. The information of demography, nature and mechanism of injury, time and ways of treatments and outcomes was reviewed. Diagnosis of SO was made based on a history of ocular trauma or surgery and subsequent development of bilateral or contralateral uveitis consistent with SO. Any association between related parameters and development of SO was analyzed.

RESULTSAmong 9103 patients (9776 eyes) of globe injury, SO occurred after open globe injury in 18 cases with an occurrence rate of 0.37%, vitrectomy of closed globe injury in 2 (0.37%) and perforation of burned eyes in another 2. For open globe injury, the median age ((36.72 +/- 13.59) years, P = 0.01) was higher in patients with SO; there were no significant effects of sexes, injury type, uvea proplaps, once or multi-intraocular surgery, once or multi-vitrectomy and endophthalmitis on incidence of SO; 0.70% endophthalmitis concurred with SO; 83.33% of SO occurred within 1 year after injury or last ocular surgery. SO developed in a fellow eye one week after evisceration of the perforating burned eye. Good final visual acuity was obtained in sympathizing eyes with prompt treatment.

CONCLUSIONSFor open globe injuries, SO sufferers were relatively older and any injury type could induce SO with equal possibility. The initial open globe injury was more likely to be the trigger of SO than subsequent intraocular surgeries including vitrectomy. Prophylactic enucleation after injury is not recommended.

INTRODUCTIONThe purpose of this study was to characterise and describe the epidemiology of all eye injuries presenting to the National University Hospital (NUH).

MATERIALS AND METHODSA prospective study was conducted over a 7-week period (11/4/2005 to 29/5/2005) on all ophthalmic trauma patients seen by the Department of Ophthalmology in NUH. Data on patient presentation, source of injury and intervention were collected via a standardised interview and examination, and documented using a validated datasheet.

RESULTSA total of 133 patients, and 139 eyes, were included in the study. The average age was 33.5 years, with a range of 5 years to 88 years, and 84.2% (n = 112) were men. Close to half (46.6%, n = 62) of the patients studied were non-Singaporeans. 56.4% (n = 75) of all eye injuries were work-related and only 5% (n = 7) of eyes were open-globe injuries. Common sources of eye trauma included: Use of high-powered tools in activities such as grinding, welding and hammering (38.3%, n = 51), human-inflicted injuries (12.0%, n =16) and road traffic accidents (8.3%, n = 11). Of the work-related eye injuries, 29.3% (n = 22) reported to having used personal protective equipment (PPE) at the time of injury, 38.7% (n = 29) had been issued PPE but had not used them, while 32% (n = 24) reported that PPE had not been issued. An initial visual acuity of 6/12 or better was found in 63.0% (n = 88) of patients and a reading of 6/60 or worse was found in 10.0% (n =14). Superficial foreign bodies (22.4%, n = 55) were the most common clinical finding, followed by periorbital bruise (12.2%, n = 30), lid ecchymoses (6.9%, n = 17), orbital fractures (6.5%, n = 16), lid laceration (6.1%, n = 15) and corneal abrasions (5.7%, n = 14).

CONCLUSIONThere is a broad spectrum of causes, mechanisms and severity of ophthalmic injuries seen in the hospital, of which work-related trauma makes up a significant proportion. The patients who suffer occupational injuries are a well-defined group: Young, non-Singaporean males, working with power tools in the construction industry are at particular risk. Although preventive strategies are in place for this high-risk group, the lack of awareness and compliance limit their effectiveness. The adequacy and functionality of PPE should be emphasised. In addition, preventive efforts are equally important in domestic, recreational, sports and transport settings. Eye trauma research and prevention can be further aided by a collaborative registry of eye injuries. A long-term islandwide database of all ophthalmic injuries is recommended.

INTRODUCTIONThe aim of this study was to determine if racial differences exist in the rate of posterior capsule rupture (PCR) during cataract surgery in Singapore.

MATERIALS AND METHODSAll intraoperative complications during cataract surgery were prospectively reported as part of a clinical audit programme. A retrospective review of all patients who sustained a PCR during cataract surgery between July 1995 and December 1998 was performed.

RESULTSOf 8230 consecutive eyes which underwent cataract surgery, 6951 (84.5%) were Chinese, 597 (7.3%) were Malay, 524 (6.4%) were Indian, and 158 (1.9%) were of other races. The overall incidence of PCR was 1.9%. The PCR rates were 1.8% [125 of 6951; 95% confidence interval (CI), 1.49 to 2.11] in Chinese, 2.0% (12 of 597; 95% CI, 1.01 to 3.57) in Malay, 2.7% (14 of 524; 95% CI, 1.13 to 3.56) in Indian, and 2.5% (4 of 158; 95% CI, 0.00 to 4.98) in other races. There was no statistical difference between the PCR rates (P = 0.62, chi-square test).

CONCLUSIONRacial differences in Singapore do not have an effect on the rates of PCR during cataract surgery.
