Perforating ocular trauma due to shotgun pellet - Clinical profile and visual outcome.

Purpose: The aim of this study was to determine visual and anatomical outcome of perforating injuries due to shotgun pellet. Methods: This was a prospective observational study carried out between July 2016 and Jan 2019 at a tertiary care referral center in Srinagar, Jammu and Kashmir. A total of 172 eyes with perforating injuries of 170 patients were included in the study and were followed up for 6 months with best-corrected visual acuity, slit-lamp examination for status of anterior chamber and lens, fundus examination for status of retina and media, intraocular pressure measurements, and OCT (optical coherence tomography) and FFA (fundus fluoresceine angiography) in selected cases. The relative improvement of visual acuity after treatment was interpreted by applying paired two-tailed t tests. Prognostic significance of other variables was calculated using Chi-square and Chi-square for linear trend tests, for two dependent outcome variables of good outcome and poor outcome. Results: WHO category 4 visual impairment was found in 66 (38.4%) eyes, whereas category 0 was found in 24 (14%) of eyes. Retina was found to be attached 99 (57.6%) of study eyes. Conclusion: Perforating injury is a severe form of ocular trauma with grave consequences in terms of functional and anatomical outcome.

Transcranial lateral perforating gunshot injury through skull base presenting without residual damage: A fortunate survivor.

We reported a case of a 32 years old male presenting with a perforating gunshot injury in craniocerebral region 3 h after the assault. The bullet entered above the right zygomatic arch, travelling through the coronal plane, and exited from the left zygomatic arch. The patient was fully conscious at presentation and developed facial nerve palsy during his hospital stay. Non-contrast CT scan of the head revealed fractures of the right orbit, bilateral maxilla, bilateral pterygoid plates, ethmoid air cells, vomer and left zygoma, and without any cerebral damage. He was treated conservatively and the facial palsy was resolved. The patient survived without any complications. Such case has not been described in the available literature till date.

Demographic characteristics and visual outcomes of open globe injuries in a tertiary hospital in Istanbul, Turkey.

PURPOSE: To evaluate the demographic characteristics and visual outcomes of patients with open globe injury (OGI) in a tertiary hospital in Istanbul, Turkey. METHODS: The data of patients admitted with OGI to Sisli Hamidiye Etfal Training and Research Hospital, Istanbul, Turkey from January 2012 to December 2017 were reviewed retrospectively, and 100 of the 154 patients were included in the study. RESULTS: There were 79 (79%) male and 21 (21%) female patients with the average age of 33.7 ± 20.7 (1-83). Presentation of the patients was more frequent in the first 3 days of the week (Monday 20%; Tuesday 17%; and Wednesday 20%) and within working hours (8 a.m.-5 p.m., 71%). The most common injury type was penetrating injury (75%), which was mostly caused by sharp objects (metal objects 32% and broken glass 22.7%). The ocular trauma score (OTS) was significantly higher in patients with penetrating injury and intraocular foreign body injury (p < 0.001), and those results were correlated with better visual prognosis. The patients with penetrating injury among the injury types and zone I injury among the injury zones had the highest final visual acuity. Patients in the age group of 0-14 years had statistically better visual outcome when compared to those in the other age groups (p = 0.003). CONCLUSIONS: The higher initial visual acuity and OTS, penetrating injury, zone I injury and pediatric age are good prognostic factors for OGI. Additionally, scheduling a prepared surgical team and tools in working hours will be beneficial according to the frequency of admissions.

Effectiveness and prognosis of 23G vitrectomy for perforating ocular trauma caused by metallic foreign bodies / 国际眼科杂志(Guoji Yanke Zazhi)

@#AIM: To summarize the characteristics of ocular perforation caused by metallic foreign body, evaluate the effectiveness and safety of 23G vitrectomy, and analyze the factors that affect the final vision of patients with ocular trauma score. <p>METHODS: Continuous observation and analysis from July 1, 2014 to June 1, 2016, hospitalized in our hospital caused by metallic perforating ocular trauma for 23G vitrectomy in 38 cases(38 eyes). A prospective collection of patient included age, gender, eye, place of occurance of trauma, foreign body size, wound length, foreign body position, initial visual acuity and final visual acuity, macular etc.. The ocular trauma score(OTS)system was used to assess the effectiveness and prognosis of the patients. The follow-up time was over 6mo. <p>RESULTS: There were 38 eyes in 38 patients, including 37 males and 1 females, aged 16y-56y. Ocular trauma mainly occurred in the workplace, 33 cases accounted for 87%, followed by sports venues, 3 cases accounting for 8%. Corrected visual acuity more than 0.1 in eyes with intraocular foreign bodies underwent 23G vitrectomy were 21 cases, accounting for 55%. Preoperative retinal detachment, large foreign body(more than 5.0mm), damage of lens were important factors of poor prognosis. Foreign bodies were located in the vitreous body in 23 cases, accounting for 61%, located in the retina in 15 cases, accounting for 39%. When admitted to hospital, the patients suffered from retinal detachment in 21 cases(55%), endophthalmitis in 7 cases(18%), the size of intraocular foreign bodies(IFOB)was larger than 5.0mm in 7 cases(18%), severe postoperative proliferative vitreoretinopathy(PVR)was in 6 cases(16%), epiretinal membrance of macula in 5 cases(13%). Of the same OTS scores, visual acuity in 6mo was significantly better than preoperative; no matter preoperative vision or postoperative vision in 6mo, the higher the OTS scores, the better the visual acuity. <p>CONCLUSION: The ocular perforation caused by metallic foreign body mostly occurs in young men under 40y, and the main reason is injury in the workplace. No protective measures are adopted. The main factors affecting the final visual acuity are retinal detachment, foreign body greater than 5.0mm and postoperative PVR appearance after the injury, vitrectomy time has little effect. The 23G vitrectomy is safe, reliable and effective in the treatment of ocular penetrating injuries due to metallic foreign bodies. OTS score can be used effectively in patients with ocular perforation caused by metallic foreign bodies and make reasonable and useful postoperative visual acuity prediction.

[Bilateral eye injuries by external transversal force]. / Bilaterale Augenverletzung durch transversale Gewalteinwirkung.

A 49-year-old female victim of violent crime with an acute bilateral loss of vision was referred to our hospital. The ophthalmological evaluation showed complete subconjunctival hemorrhage of both eyes, bilateral hemophthalmos and hypotonia of the left eye. These raised the suspicion of an occult scleral rupture. We immediately performed exploratory surgery and found a perforating scleral lesion of the left eye and a penetrating scleral lesion of the right eye. Furthermore, a small, cruciform wound was detected on the left temple. In cooperation with the department of radiology, the extraordinary injury pattern was reconstructed: a horizontal stab wound with perforation of the left eye and penetration of the right eye caused by a screwdriver. Visual rehabilitation necessitated further surgical interventions. Besides the intraoperative approach, immediate primary wound management within 100 h of trauma plays a pivotal role for long-term outcome.

Review Of Ocular Injuries In Malaysia

Ocular injuries or trauma to the eye can be caused by variety of objects resulting in a spectrum of lesions in the eye. We did a Pubmed/Google/Science Direct search to review the spectrum of ocular injuries in Malaysia. In our review, we included 28 papers providing information on ocular injuries which were published from Malaysia during the period 1991-2016 in different medical journals. Prevalence was more among males with an average age of 35 years. Among adults they were more common in the workplace but in children it occurred at home. Few wore protective glasses at work. The mode of injury was due to sharp objects hitting the eye, motor vehicle and domestic accidents, firecrackers, chemicals and rarer causes like superglue and durian fruit. Prognostic factors for outcome were the initial visual acuity, length of the wound, associated factors like hyphaema, intraocular foreign body and vitreous prolapse. Missing the diagnosis of perforation of the eyeball is possible without eliciting a proper history. Protective devices must be worn to prevent injuries. Display of health education charts showing the effect of injuries in the eye and their preventive measures in health centres, private hospitals, schools, factories and sports centres will increase the awareness of public about the ocular injuries. It is important to diagnose the tissues involved in ocular trauma by the general practitioners and primary care physicians and refer the patients to the Ophthalmologist urgently for treatment to salvage vision. Compensation mechanisms should then be put forth in terms of rehabilitation and for monetary loss.

Endophthalmitis after tooth extraction in a patient with previous perforating eye injury.

The aim of this stuty is to describe a case of endophthalmitis after tooth extraction in a patient with previous perforating eye injury. 50 years old male patient attempted to our clinic with complaints of sudden severe pain, reduced vision, light sensitivity and redness in the right eye. The patient stated that severe pain in his eye began approximately 12 hours following tooth extraction. The patient's ocular examination revealed a visual acuity of hand motion in the right eye. Anterior segment examination of the right eye showed intense conjunctival hyperemia, chemosis, a fine keraticprespitat and corneal edema. Dental procedures of the patients who had recently underwent ocular surgery or trauma should be done in a more controlled manner under anti -infective therapy or should be postponed in elective procedures.

Perforating corneal injury in rat and pentadecapeptide BPC 157.

Based on its healing effects in various tissues, we hypothesized that the stable gastric pentadecapeptide BPC 157 heals corneal ulcerations in rats and effects corneal transparency. We made a penetrant linear 2-mm incision in the paralimbal region of the left cornea at the 5 o'clock position with a 20-gauge MVR incision knife at 45° under an operating microscope. Medication was BPC 157 (2 pg/mL, 2 ng/mL, and 2 µg/mL distilled water, two eye drops/left rat eye) immediately after injury induction and then every 8 h up to 120 h; controls received an equal volume of distilled water. In contrast to the poor healing response in controls, BPC 157 significantly accelerated the healing process in 2 µg and 2 ng BPC 157-treated eyes, starting 24 h after the injury, and the fluorescein and Seidel tests became negative. The epithelial defects were completely healed at 72 h (2 µg BPC 157-treated group) and at 96 h (2 ng BPC 157-treated group) after injury. Aqueous cells were absent at 96 h and 120 h after injury in the 2 µg and 2 ng BPC 157-treated groups, respectively. In conclusion, BPC 157 effects the rapid regaining of corneal transparency. Whereas controls developed new vessels that grew from the limbus to the penetrated area, BPC 157-treated rats generally had no new vessels, and those that did form in the limbus did not make contact with the penetrated area. Thus, BPC 157 eye drops successfully close perforating corneal incisions in rats.
