Value of ocular trauma score in predicting the incidence of secondary glaucoma after closed globe injury

Aim To analyze the visual acuity (VA) and the incidence of secondary glaucoma among patients with closed globe injury (CGI). To determine the correlations between the ocular trauma score (OTS) with surgery rate, and evaluate the applicability of OTS in secondary glaucoma prediction and treatment. Methods We conducted a retrospective review of 265 patients (265 eyes) with CGI admitted to Xijing Hospital between January 2014 and December 2016. The clinical characteristics; VA, IOP, injury zone, surgery, and IOP-lowering medications were collected at the initial visit and at six months. The patients with secondary glaucoma were scored and assessed by the OTS system. The correlation of the anti-glaucoma surgery with the OTS was evaluated. The difference in the number of IOP-lowering medications between the initial visit and six months was analyzed. Results The average age of the patients was 33.5 ± 20.7 years with 80.8% being males. The final VA outcome improved in its totality after treatment. 35 patients developed glaucoma, with an incident rate of 13.2% over six months. All glaucoma patients had an injury in zone I and II, and 12 of them had an injury in zone III. The severity of the OTS category showed a strong correlation with the anti-glaucoma surgery rate. After the surgical intervention, the number of IOP-lowering medications in OTS category 2, 3, and 4 significantly reduced. Conclusions The OTS has predictive value in the incidence of secondary glaucoma after CGI. A patient with a low score is more likely to develop secondary glaucoma and might require surgical intervention.

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.

A prospective study to evaluate the predictive value of ocular trauma score in cases of mechanical eye injuries in a tertiary care hospital

Ocular trauma score (OTS) was proposed to predict the visual outcome of patients after ocular trauma, which estimates visual function (visual acuity) after 6 months of ocular trauma. This OTS scale is useful for guiding the treatment and rehabilitation of the patients with eye injury and to provide the valuable information and advice. Aim of this study was to evaluate the predictive value of OTS in cases of mechanical ocular trauma. A prospective interventional study was carried out in a tertiary care centre over a period of 2 years; August 2017 to July 2019. Patients with mechanical eye trauma were included in the study. OTS score was calculated and recorded for each eye at the time of injury. Proper treatment given to each case and followed for six months. Results obtained were compared with standard OTS with respect to final VA. Out of 50 patients mean age was 28.46 years, with majority between 21 to 50 years of age. There were 78% males and 22% were females. Metallic objects were the common source of injury in 27 cases (54%) like iron rod and nail. In cases (fifty eyes) the distribution of OTS variables was; globe rupture 86% (43 eyes), retinal detachment 6% (3 eyes), relative afferent pupillary defect (RAPD) 6% and endophthalmitis 2% (1 eye) respectively. The final visual acuities in OTS categories in our study groups were similar to those in the OTS study group, except for some categories. OTS helps treating ophthalmic team to assess evidence based prognosis of a traumatized eye in advance. With the guidance of OTS the patient and their family can be counselled for further management.

Trauma Okular oleh Serangan Kerbau – Laporan Kasus

Of the many ocular blunt traumas, trauma due to typical buffalo attack thrrough leverage has not been reported. We reported a 65-year-old man attacked by a buffalo on his left eye. The patients complained of pain of his left eye associated with swelling, bleeding, and blurred vision. Eye examination revealed that visual acuity of the left eye was classified as hand motion (HM), limited ocular motility, blepharospasm, and a crescent-shaped anterior lamella laceration with lateral canthal involvement. Anterior segment examination revealed bullous subconjunctival hemorrhage, corneal edema, and rosette-shaped opacification (RSO) of the lens. Head-CT showed traumatic cataract and periorbital haemorrhage; no abnormalities in the right eye. Ovular trauma score (OTS) of the patient was three indicating that the possible visual prognosis was 2% as no light perception (NLP), 11% as light perception (LP) or hand motion (HM), 15% as 1/200-19/200, 31% as 20/200-20/50, and 41% as >20/40. Literature data showed that the visual sensitivity of OTS prediction in NLP, 20/200-20/50, and 20/40 was 100%. The specificity of OTS in predicting vision in LP/HM 1/200-19/200 was 100%. After a recovery period of approximately two months and the sutured wound healed, the patient came to the eye clinic of Prof. Dr. R. D. Kandou Hospital Manado. After a cataract surgery was performed on the left eye of the patient, his visual acuity improved to 20/40.Keywords: ocular trauma, buffalo attack, ocular trauma score (OTS) Abstrak: Dari sekian banyaknya trauma tumpul, trauma akibat rudapaksa tipikal serangan kerbau yang menggunakan gaya ungkit belum pernah dilaporkan.

Factors affecting final functional outcomes in open‐globe injuries and use of ocular trauma score as a predictive tool in Nepalese population

Background Open globe injury (OGI) is one of the most devastating form of ocular trauma. The aim of the study is to identify the epidemiology and predict visual outcomes in traumatic open globe injuries using ocular trauma score (OTS) and correlate with final visual acuity (VA) at 3 months. Methods Patients older than 5 years, presenting to B.P. Koirala Lions Centre for Ophthalmic Studies (BPKLCOS) from March 2016- March 2017 with OGI that met inclusion criteria were evaluated. Patient profile, nature and cause of injury, and time to presentation were recorded. Patients were managed accordingly and followed up to 3 months. An OTS score for each patient was calculated and raw scores were categorized accordingly. The VA after 3 months were compared to the predicted OTS values. Results Seventy-three eyes of 72 patients were examined. 76 % were male, and the mean age was 26.17 years (median, 23.5 years). The mean time from injury to presentation was < 6 hours (30 patients, 41 %). Thirty-seven eyes (51 %) had zone I trauma, followed by twenty eyes (27 %) with zone II, and sixteen eyes (22 %) with zone III trauma. Sixty-five patients (90 %) were managed surgically, and fifty (68 %) received intravitreal antibiotics with steroid. When compared, the projected VA as per OTS were able to predict actual final visual outcomes in 60 % of the eyes with OGI of various zones. Conclusions OTS can be an accurate predictive tool for final visual acuity even with a short follow up period of 3 months; with poor presenting visual acuity, delayed presentation, posterior zones of injury, need for intravitreal injections, endophthalmitis, and globe rupture associated with poorer prognosis.

Traumatic open globe injury—epidemiology, risk factors and visual outcome at the University Hospital Aachen

Summary Background Ocular trauma is still a major cause leading to enucleation. This study aims to analyze the visual outcome, epidemiology and risk factors of open globe injury (OGI) at the University Hospital Aachen, Germany. Material and methods A retrospective analysis of patient records involving traumatic OGI treated surgically between 2005 and 2015 was conducted. Age, gender, cause of accident, ocular trauma score, best corrected visual acuity (BCVA) at presentation and after treatment as well as location of injury were evaluated. Results Of 2272 eyes with trauma, 102 patients with OGI were identified, of which 65% were male and 35% were female. Women were significantly older than men (p < 0.001). The most common cause of injury was domestic syncopal episodes (47%). Work-related injuries occurred exclusively in men in 8.8%. A total of 16% had no light perception (NLP) at presentation, 69% of which improved post intervention to hand movement or better. Endophthalmitis was observed in 4% of all cases. Enucleation was needed mostly due to rupture. Location of OGI, pseudophakia and initial BCVA are risk factors for poor final BCVA. Patients’ BCVA did not improve further after three surgeries. Conclusion Traumatic OGI still poses a challenge in terms of treatment planning and prognostic outcome. A rise in elderly patients with multimorbidity represents a secondary obstacle to treatment. Patients with initial NLP can be treated with moderate success. Nevertheless, risk factors and ocular trauma score are unable to provide definitive therapy decisions. OGI should be assessed case by case, taking risk factors for OGI into account. Treating physicians should consider the ethical and economic reasons with regard to whether a high number of surgeries with possible comorbidities is justified.
