Prognostic factors for visual outcome after surgical repair of limbal corneal laceration at a tertiary eye care center in South India

Purpose: To determine the factors affecting the visual outcome after surgical repair of limbal corneal lacerations at a tertiary eye care center in South India. Methods: A retrospective analysis of patients diagnosed with limbal tears between 2011 and 2021 was conducted. Demographic information such as age, gender, cause of injury, and size of the laceration was recorded. Comprehensive ocular examination was performed, including gentle B scan evaluation whenever not contraindicated for detailed posterior segment evaluation. Only those cases with a minimum follow?up of one year were included. Postoperative best?corrected visual acuity, intraocular pressure (IOP), cornea clarity, and integrity of the wound at last follow?up were noted. Results: Out of the 20 patients, 15 (75%) were males and 5 (25%) were females. The mean age was 42.6 � 22.4 years. All 20 patients had a penetrating injury, with four (20%) injured by a stick, two (10%) by an iron rod, three (15%) due to road traffic accident (RTA), three (15%) by glass, and eight (40%) with other nonspecific objects [two (10%) with needle, two (10%) with elastic rope, two (10%) with bangle, and two (10%) with metal]. The average time between the injury and the surgery was 48 hours (2 days). Four (20%) patients underwent a second surgery within a week of repair. After limbal tear repair, at final follow?up at 3 years, 7 (35%) had VA worse than 20/800, 3 (15%) had VA between 20/100 and 20/800, and 10 (50%) achieved VA better than 20/80. Conclusion: Preoperative visual acuity (VA), mode of injury, and size of wound affect the final visual outcome after surgical repair of limbal corneal laceration. Preoperative VA and mode of injury were statistically significant even in the multivariate analysis.

A series of 777 pellet gun ocular injuries over a 4-month period in Kashmir

Purpose: To examine the incidence, clinical findings and management of pellet gun–related ocular injuries that occurred during protests in Kashmir region. Methods: This retrospective study included records from 777 patients diagnosed with pellet gun–related ocular injuries admitted to a tertiary hospital in Srinagar, India, between July and November 2016. By reviewing the clinical records, the following data were collected: demographics, clinical information pertaining to the injury, imaging reports including computer tomography and ultrasonography B?scan, management in the emergency setting, and follow?up treatment. Results: Mean age was 22.3 ± 7.2 years and majority patients were male (97.7%). In terms of laterality, 94.3% and 5.7% of the patients sustained monocular and binocular injuries, respectively. In terms of the nature of injury, 76.3% of the eyes had open globe injury while 23.7% of the eyes had closed eye injury. Emergency surgical exploration was performed in 67.7% of closed globe injuries while emergency primary repair was done in 91.1% of open globe injuries. The vast majority of patients (98.7%) who required surgery underwent surgical intervention on the day of admission or the next day. Final best?corrected visual acuity (BCVA) after treatment was counting fingers or worse in 82.4% of the eyes. Conclusion: Pellet gun–related ocular injuries resulted in significant ocular morbidity, mostly manifesting as open globe injuries. Treatment often required surgical interventions, but despite expeditious management, visual prognosis remained poor for most of the patients.

Open globe injuries from projectile impact: Initial presentation and outcomes

Purpose: To describe the characteristics and correlates of open globe injuries secondary to projectile injury and outcomes following surgical open globe repair at an urban tertiary referral center. Methods: Records of all patients with a history of open globe injury secondary to projectile injury and surgical open globe at a tertiary referral hospital between January 1, 2010 and December 31, 2016 were reviewed. Demographics, type of trauma, wound extent, presence of foreign body, and presenting clinical findings are reported. Outcomes for patients with greater than 6 months of follow?up included additional surgeries, final visual acuity, and clinical findings. Results: Of 214 patients who underwent open globe repair, 73 (34.1%) were due to projectile impact. Mean age was 37.9 years and patients were primarily male (n = 66, P < 0.001). Most injuries resulted in globe laceration (68.5%, P < 0.001), and wound extent was zone 1 (45.2%), zone 2 (20.5%), zone 3 (27.4%), or unknown (6.8%). Associated findings included foreign body (35.6%) and orbital fracture (15%). Of 41 patients with at least 6 months of follow?up, 70% had additional surgeries following their initial surgical repair. Laceration injuries tended to be more anterior (P = 0.002) with better visual outcomes (P = 0.045) than those with globe rupture, and concomitant orbital fracture associated with poor visual outcomes. Overall, 58.5% of patients had 20/40 or better final best?corrected visual acuity. Conclusion: This is the largest report of open globe injury due to projectile impact. Visual prognosis in this population is very good, with most patients achieving better than 20/40 vision in our study

Study on factors in patients to get rid of blindness with post traumatic infectious endophthalmitis / 国际眼科杂志(Guoji Yanke Zazhi)

AIM:To investigate the factors affecting patients with post traumatic infectious endophthalmitis(PTIE)relieving from blindness.METHODS: A retrospective study was conducted on 169 patients(169 eyes)with PTIE from January 2010 to December 2020 in the department of ophthalmology, the Affiliated Hospital of Nantong University. After treatment of intravitreal injection of antibiotics(IVIA)and/or pars plana vitrectomy(PPV), the patients were divided into the getting rid of blindness group(103 eyes)and unilateral blindness group(66 eyes)according to the last follow-up of best correct visual acuity(BCVA)≥0.05. The factors affecting the patients to get rid of blindness were analyzed.RESULTS: The rate of relieving from blindness was 53.5%. Univariate analysis showed that BCVA before treatment ≥ hand movement, no retinal detachment, fundus grade of endophthalmitis < grade 3 and no strong virulence of infected microorganisms were beneficial for patients to get rid of blindness(P<0.05). Multivariate Logistic regression analysis identified that BCVA before treatment ≥ hand movement(OR=0.253, 95%CI: 0.108-0.592)and no retinal detachment(OR=0.241, 95%CI: 0.103-0.564)were favorable factors for patient to get rid of blindness.CONCLUSION: Better BCVA before treatment, no retinal detachment, endophthalmitis fundus grade < 3, and no strong virulence of infected microorganisms are favorable factors for patients with PTIE to get rid of blindness finally.

Incidence, clinical profile, and short-term outcomes of post-traumatic glaucoma in pediatric eyes

Purpose: To report the incidence, modes of injury, treatment, and short-term outcomes in eyes with post-traumatic elevated intraocular pressure (IOP). Methods: This was a 5-year hospital-based retrospective study of children ?16 years who presented with open (OGI) or closed globe injury (CGI) and developed elevated IOP >21 mmHg. Those with a minimum follow up of 3 months were included. Analysis of various parameters such as influence of demographics, mode of injury, IOP, best-corrected visual acuity (BCVA), and effect of medical and surgical treatment on IOP and BCVA was done. Results: Out of 205 pediatric eyes with ocular trauma, 121 (59%) had CGI and the remaining 84 (41%) had OGI. Thirty-two eyes (15.6%) developed elevated IOP. The incidence of elevated IOP following CGI [25 eyes (20.6%)] was significantly higher than that following OGI [7 eyes (8.3%, P = 0.02)]. Hyphema (37.5%) and lens-related mechanisms (18.75%) were the most common causes of elevated IOP. The mean IOP at the time of diagnosis was 29.8 + 6.3 mmHg and reduced to 16.2 ± 2.2 mmHg at last follow up (P < 0.001). Surgical management was required in 12 eyes (37%) and significantly more eyes with CGI required trabeculectomy (24% in CGI vs. 0% in OGI, P = 0.03). Poor baseline vision and vitreoretinal involvement [0.67 line decrement, 95% confidence interval (CI) =0.1–1.25 lines, P = 0.025] increased risk of poor visual outcome. Conclusion: Post-traumatic IOP elevation occurred in 15% pediatric eyes, was more common with CGI compared to OGI and nearly one-fourth of eyes with CGI required glaucoma filtering surgery for IOP control. Overall, medical management was needed in 63% eyes and 37% required surgical management. Visual acuity was poor in eyes with OGI due to posterior segment involvement.

The Relationship between Visual Outcome and Ocular Trauma Score after Open Globe Injuries in Children

PURPOSE: We evaluated the prognostic factors of open globe injuries in children and adolescents, and compared the ocular trauma score (OTS) and pediatric penetrating ocular trauma score (POTS). METHODS: We performed a retrospective review of 77 children under 18 years of age who visited our clinic with open globe injuries between May 1993 and April 2014. We investigated the factors that may affect final visual acuity. We also compared the OTS and POTS using receiver operating characteristic curves as a method to predict final visual acuity. RESULTS: By univariate analysis, an initial visual acuity less than 20/200, globe rupture, wound size greater than 7.0 mm, retinal detachment, lens dislocation, and total number of operations contributed to worse visual outcomes (<20/200). Conversely, central corneal involvement, traumatic cataract, wound size less than 7.0 mm, and initial visual acuity greater than 20/200 were better prognostic indicators (≥20/32). Both OTS and POTS had diagnostic value as a predictor of final visual acuity, although there were no statistically significant differences between the two scoring systems. CONCLUSIONS: Initial visual acuity and wound size are important prognostic factors for the final visual acuity in children and adolescent, following open globe injuries. Both OTS and POTS are reliable prognostic models for open globe injuries in children and adolescents.

Open Globe Injury in Hospital Serdang - An 8-year Retrospective Review

Introduction: Open globe injury may lead to devastating visual outcome. Urgent management and subsequent follow-up is important to maximise recovery. More data on open globe injury in Malaysia is needed to identify risk groups and prognostic factors. This study was carried out to investigate open globe injury, the socio-epidemic profile, clinical characteristics and outcome of the open globe injury in the Hospital Serdang, Malaysia. Methods: All patients managed for open globe injury to Hospital Serdang from January 2006 to December 2013 were included in this retrospective case review. Student’s T-test was used to determine difference between means and chi-square for categorical data. P value of less than 0.05 was regarded as statistically significant. Results: There were 155 patients managed for open globe injury with three of them had bilateral involvement. As such, there were 158 cases eligible for analysis in this study. The average age was 32.2 ± 16.5 years (mean ± standard deviation, SD). Male was at higher risk for open globe injury. Predictors for poor visual outcome were foreign nationality (p=0.047), lid laceration (0.008), type of injury (p=0.001), site of injury (p=0.008), RAPD (p<0.001), uveal prolapse (p<0.001), hyphaema (p=0.008), lens damage (p=0.010), vitreous loss (0.014), retinal detachment (p=0.011), intraocular foreign body (IOFB) (0.014) and poor presenting uncorrected visual acuity (UCVA) (p<0.001). Conclusions: Occupational injury was a main cause of open globe injury in Hospital Serdang. Although in general the visual outcome is good, effort should be put to prevent work-related injury.

Changes in the Clinical Manifestations of Ocular Injuries Induced by Power Lawn Mowers

PURPOSE: To investigate changes in the clinical manifestations of ocular injuries induced by power lawn mowers. METHODS: In a retrospective study of 172 patients with ocular injuries induced by power lawn mowers in 2006, 2010, and 2014. Best corrected visual acuity (BCVA) at the time of presentation and 6 months after trauma, age, sex and seasonal distribution were analyzed. We assessed the degree of injury using slit lamp biomicroscopy, fundus examination, and computed tomography and analyzed the prognoses according to open/closed injury and, anterior/posterior segment injury. All patients underwent medical or surgical treatment, and the factors affecting final BCVA were analyzed. RESULTS: The ratio of closed injuries increased significantly (p = 0.027), as did the ratio of corneal erosion (p = 0.020), and, the ratio of corneal laceration decreased significantly (p = 0.014) over time. In the multivariate analysis, initial BCVA was the only risk factor of poor visual outcome in both open and closed injuries. CONCLUSIONS: The proportion of open globe injury has decreased over time. In contrast, the proportion of simple injuries such as corneal erosion has increased in ocular injuries induced by power lawn mowers. Lower initial visual acuity was the only risk factor of poor visual outcome in both open and closed injuries.

Pattern of ocular trauma in tertiary care hospital in Khammam.

Background: Ocular trauma is an important public health hazard. The objective of the study was to determine the pattern of ocular trauma among patients presenting in Mamata Medical College and Hospital, Khammam. Methods: Two years retrospective review of records of 120 patients with ocular trauma seen from Jan 2013 to Feb 2015 was done using a structured format. Results: Ocular trauma accounted for 1.2% of the total ocular patients seen at OPD and Emergency. Of the studied 120 cases, 74 patients were below 30 years of age. 17 (14.16%) patients presented to hospital within 2-7 days of injury. Conclusion: Duration of presentation has significant association with the presence of infection & other complication. The cause of injury were road traffic accidents, occupation related and sports playing & recreational activities in 54(45%), 39(32.5%) and 24(20%) respectively. Closed globe injuries accounted for 38(31.66%) and open globe for 58(48.33%) and adenexal injuries constituted 24(20%). Delay in presentation was associated with complications.

Risk Factors and Clinical Manifestations of Ocular Hypertension after Primary Repair of Open Globe Injury

PURPOSE: To investigate the risk factors and clinical manifestations of ocular hypertension (HTN) after repair of open globe injury (OGI). METHODS: In a retrospective study of 284 patients who underwent primary repair of open globe injury at the day of trauma, best corrected visual acuity (BCVA) at the time of trauma and 6 months postoperatively, length of laceration, location of laceration and mean intraocular pressure (IOP) at 1 month after primary repair were analyzed. Presence of iris injury, lens injury, intraocular foreign body (IOFB) and vitreous hemorrhage (VH) were also analyzed. Ocular hypertension was defined as elevation of IOP greater than or equal to 21 mm Hg over 3 measurements. RESULTS: Fourteen (4.93%) of 284 patients had ocular hypertension. BCVA (log MAR) at the time of trauma in the ocular HTN group was significantly worse than in the normal IOP group (2.43 +/- 1.04 and 1.76 +/- 1.30, respectively, p = 0.033). In the multivariate analysis, ocular HTN increased significantly with IOFB (p = 0.038; odds ratio [OR], 3.584; 95% confidence interval [CI], 1.075-11.941) and VH (p = 0.028; OR, 3.971; 95% CI, 1.157-13.624). BCVA increased significantly after repair in both groups and mean IOP was well controlled after medical therapy (9 eyes) or surgical treatment (5 eyes) in the ocular HTN group (28.1 +/- 4.7 and 15.8 +/- 3.8, respectively, p < 0.01). CONCLUSIONS: Ocular HTN increased significantly with IOFB and VH at the time of trauma after repair of OGI and can be effectively treated by medication or surgical approach.

Gender Disparities in Open Globe Injuries: Ten- Year Review of an Urban Population.

Aims: To characterize gender differences in the ophthalmic findings and clinical outcomes of patients with open globe (OG) injuries. Study Design: Retrospective case series. Place and Duration of Study: Department of Ophthalmology, University Hospital, New Jersey Medical School between January 2001 and June 2010. Methodology: The medical records of all patients presenting with OG injuries to University Hospital, Newark, NJ from January 1, 2001 through June 30, 2010 were reviewed. Demographics, characteristics of the trauma, ophthalmic findings, and outcomes were compared in male and female patients. Results: A total 603 eyes (602 patients) with OG injuries were identified. Most of the patients (76.4%) were male. The mean patient age was 39.14 years which was significantly lower in males (35.66 years vs. 50.43 years in females; p<0.001). The vast majority of injuries were penetrating and/or work-related in men, whereas fall-related ruptures comprised the most common pattern of injury in women. Zone I was the most commonly injured zone in both genders, and Zone III wounds were more commonly seen in males (p=0.03). Although females were more likely to present with a worse visual acuity (VA, p=0.005), the final VA was not significantly different between males and females (p=0.06), and a statistically significant improvement in vision occurred in both genders (p<0.001 in both). Fifteen percent of patients had an unfavorable anatomic outcome and underwent either primary or secondary enucleation; the rate was not different among males and females (17% in both). Conclusion: Male and female victims of OG injuries follow different trends in terms of demographics, etiology, and type of injury. This highlights the importance of applying different prevention strategies in the genders.

Prognostic factors for open globe injuries and correlation of Ocular Trauma Score at a tertiary referral eye care centre in Singapore.

Objective: To evaluate the factors influencing final vision outcome after surgical repair of open globe injuries and to correlate the Ocular trauma score. Materials and Methods: Retrospective case analysis of patients with open globe injuries at a tertiary referral eye care centre in Singapore was performed. Pre‑operative factors affecting final vision outcome in patients with open globe injury and correlation of ocular trauma score in our study with international ocular trauma scoring system was performed. Results: Case records of 172 eyes with open globe injury were analyzed. Mean age was 36. 67 years. Mean follow up was 12.26 m. Males were pre‑dominantly affected. Initial visual acuity was ≥20/40, 20/50 < 20/200, 20/200‑ CF, HM– PL and NLP in 24 (14%), 39 (22.7%), 16 (9.3%), 66 (38.4%) and 27 (15.7%) eyes respectively. Final visual acuity was ≤20/40, 20/50 < 20/200, 20/200‑ 1/200, HM– PL and NLP in 76 (44.2%), 28 (16.3%), 11 (6.4%), 30 (17.4%) and 27 (15.7%) eyes respectively. Ocular trauma score in our study correlates with international ocular trauma scoring system. Conclusion: The present study showed pre‑operative variables such as mode of injury, pre‑operative visual acuity, traumatic cataract, hyphaema, relative afferent papillary defect, vitreous lossand vitreous hemorrhage to be adversely affecting the final vision outcome. Our study showed a good synchrony with international ocular trauma score (OTS) and based on this study we were able to validate application of OTS in Singapore population. Recognizing these factors can help the surgeon in evidence based counseling.

Clinical Characteristics of Intraocular Foreign Body and Analysis of Prognostic Factors

PURPOSE: To investigate clinical characteristics of post-traumatic intraocular foreign body (IOFB), which occurred between 2006 and 2010, and prognostic factors associated with final visual outcome. METHODS: A retrospective chart review was performed of patients with IOFB who visited our clinic from January 1, 2006 to December 31, 2010, and who were followed up for more than 6 months. Cross tabulation and correlation analyses were conducted to evaluate the predictive factors related to final visual acuity. RESULTS: A total of 36 eyes (35 patients) were included in this study. The mean age was 44.2 years, and 33 patients (94.3%) were male. The most common cause of IOFB was lawnmower-related activity (12 patients; 33.3%) and hammering-related activity (11 patients; 30.1%). Among analyzed prognostic factors, only initial visual acuity was significantly correlated with visual outcomes (p < 0.001). CONCLUSIONS: Compared with previous studies, lawnmower and hammering-related activities were still the most common causes of IOFB, however, the incidence of occurrence in the 40's and 50's was relatively higher than in previous studies. Considering the poor visual outcome of IOFB even after proper surgical treatment, using proper eye protection should be emphasized in a dangerous work environment to prevent ocular trauma.

The Availability of Modified Ocular Trauma Score in Korean Patients with Open Globe Injury

PURPOSE: To modify the ocular trauma score (OTS) model by analyzing the clinical characteristics of Korean patients with open globe injury and to determine the availability of the modified OTS in predicting the final visual acuity. METHODS: Among the prognostic factors in the original OTS, endophthalmitis and perforating injury were excluded, and wound location, vitreous hemorrhage, lens damage, and lid laceration were added to the modified OTS based on the data of 242 patients with open globe injury from January 2000 to September 2010. To determine the availability of the modified OTS, 29 patients from September 2010 to December 2011, not included in the previous data, were retrospectively reviewed, and the positive and negative predictive values for assessment of final visual acuity less than 0.02 were calculated by the original and modified OTS. RESULTS: The modified OTS was applied to the previous data, and the positive predictive value was 75.3% and negative predictive value was 90.8%. By using the original OTS, the positive predictive value was 70.1% and negative predictive value was 89.8%. The values of the modified OTS was higher than those of the original OTS, but it was not statistically significant (p = 0.5956, p = 0.9370). When the modified OTS was applied to the new 29 patients, the positive and negative predictive values were 75.0% and 90.5%, respectively. CONCLUSIONS: The prognostic factors of the original OTS were modified based on the previous data and the positive and negative predictive values of final visual acuity by modified OTS were similar to those by the original OTS. The modified OTS would be useful in analyzing the patients with open globe injuries and could be used as a prognostic model for Korean patients.

Characteristics and Prognostic Factors of Open-Globe Injuries in Korea

PURPOSE: To characterize epidemiologically open-globe injuries and to identify prognostic factors for visual outcomes after open-globe injuries in Korea. METHODS: The medical records of 138 patients with open-globe injuries presenting to the Severance Hospital between January 2005 and June 2011 were retrospectively reviewed. RESULTS: Out of 138 patients, 85.5% were men. The types of injury included penetrating injury (44.2%), intraocular foreign body (15.9%), blunt injury (35.5%), and perforating injury (3.6%). The most common cause of injury was accidents at work (49.3%) and 60.9% of these injuries were a penetrating wound in zone I limited to the cornea. Predictors of poor visual outcome using univariate analysis included wound extended to posterior sclera, wound length of 10 mm or more, poor initial visual acuity of hand motion or less, and presence of associated ocular injuries at presentation including hyphema, lens injury, vitreous hemorrhage, and retinal detachment. Initial visual acuity and wound size were independent prognostic factors of visual outcome. CONCLUSIONS: Accidents at work are the most important cause of open-globe injuries in Korea. Accordingly, protective measures such as appropriate eyewear and safety education at work are warranted. Initial visual acuity and wound size predicted favorable visual outcome.

Prognostic factors for vision outcome after surgical repair of open globe injuries.

Purpose: To evaluate the factors influencing final visual outcome after surgical repair of open globe injuries. Materials and Methods: The study was carried out at a tertiary referral eye care center in Central India. In this retrospective study, case records of 669 patients with open globe injuries were analyzed. Different preoperative variables were correlated with the final visual outcome. Exclusion criteria were patients with less than four months follow up, previous ocular surgery, presence of intraocular foreign body or endophthalmitis at the time of presentation. Using statistical tests, the prognostic factors for vision outcome following surgical repair of open globe injuries were studied. Results: Based on the Spearman's Rho correlation analysis, following factors were found to be significantly associated with the final visual acuity at univariate level: age (P<0.001), preoperative visual acuity (P=0.045), mode of injury (P=0.001), and time lag between the injury and surgery (P=0.003). None of the other clinical factors have statistically significant correlation with final visual acuity. On multivariate analysis using binary logistic regression, only age, mode of injury and the time lag between injury and surgery achieved statistically significant results. Conclusion: In the current study, elapsed time between the injury and surgery, age of the patient, preoperative visual acuity and mode of injury were found to be adversely affecting the final visual outcome. Recognizing these factors prior to surgical intervention or intraoperatively can help the surgeon in evidence-based counseling of the trauma victim and family.
