We report and compare 2 cases of open globe injury with foveal damage incurred while mowing. Case 1 is a healthy 67-year-old man presenting with an intraocular metallic foreign body and eye pain in his right eye after using a mower. The foreign body perforated the cornea’s inferior area and damaged the foveal centralis, leading to central scotoma and decreased visual acuity. 27G pars plana vitrectomy was performed, and the final corrected decimal visual acuity was 0.1, but the visual field was preserved, except for the central scotoma. Case 2 is a healthy 50-year-old man presenting open globe injury with an intraocular metallic foreign body while using a mower. The foreign body damaged the fovea and triggered extensive retinal detachment. One month after surgery, proliferative vitreoretinopathy occurred, requiring additional surgery. The final corrected decimal visual acuity dropped to 0.05, resulting in an extensive visual field defect. Both cases of eye trauma were caused by mower injury, but the visual function outcomes differed with the size of the foreign body and the injury severity at the time of onset. Mower eye trauma is preventable, and efforts to educate users on safety measures are needed.

Blunt Ocular Trauma

Open globe injury (OGI) is a severe form of eye trauma. It is an important cause of monocular blindness worldwide. Ruptures from blunt trauma are most common at the sites where the sclera is thinnest, at the insertions of the extraocular muscles, and at the limbus. Most often, rupture is equatorial. We present a unique case of open globe injury due to blunt ocular trauma from a thrown rock that resulted in a meridional rupture of the eye. The pertinent literature is reviewed.

Purpose.To evaluate functional and anatomical results of pars plana vitrectomy (PPV) in the retinal detachment (RD) followed by severe eye trauma.Methods.Retrospective analysis of medical records of forty-one consecutive patients treated with 23-gauge PPV due to traumatic RD. Age, gender, timing of PPV, visual acuity, and presence of intraocular foreign body (IOFB) and proliferative vitreoretinopathy (PVR) were included in the analysis.Results.Mean age of patients was 47 years; the majority of patients were men (88%). Closed globe injury was present in 21 eyes and open globe injury in 20 eyes (IOFB in 13 eyes, penetration injury in 4 eyes, and eye rupture in 3 eyes). Mean follow-up period was 14 months; mean timing of PPV was 67 days. Twenty-seven (66%) eyes had a functional success; 32 eyes (78%) had anatomical success. As a tamponade silicone oil was used in 33 cases and SF6 gas in 8 cases.Conclusions.Severe eye injuries are potentially devastating for vision, but vitreoretinal surgery can improve anatomical and functional outcomes. Among analysed pre- and intra- and postoperative factors, absence of PVR, postoperative retinal attachment, and silicone oil as a tamponade were related to significantly improved visual acuity.

Abstract Background To evaluate the epidemiology of endophthalmitis cases related to ocular trauma, including visual acuity during and 1 year after trauma, source of trauma and method of treatment. Methods A retrospective study analyzed the epidemiological data of patients with a clinical presentation of endophthalmitis after ocular penetrating trauma between January 2012 and January 2017 at Escola Paulista de Medicina/UNIFESP, a hospital in São Paulo, SP, Brazil. Results A total of 453 patients with antecedent open globe trauma were evaluated, among these, 30 patients with suspected endophthalmitis. All patients were male. The time interval between trauma and ophthalmological evaluation and collection of vitreous and aqueous material was 1 day in 36.66%, 2–7 days in 43.44%, 7–14 days in 10% and more than 15 days in 10% of patients; 66.66% had positive cultures. 11 patients had intraocular foreign body. One year after trauma, visual acuity was classified as no light perception (NLP) in 33.33%, light perception in 6.66%, hand motion in 13.33%, counting fingers in 13.33%, and better than 20/400 in 20% of patients. Considering presence of intraocular foreign body, initial visual acuity and symptoms onset time, only initial visual acuity showed as better prognostic factor in final visual acuity. Conclusion Endophthalmitis is a severe ocular inflammatory condition that may lead to irreversible vision loss. Initially only one patient had visual acuity of NLP, but after 1 year, 33% showed visual acuity of NLP, and only 20% had visual acuity better than 20/400, what is consistent with a severe infection with a guarded prognosis. The high incidence of endophthalmitis after ocular penetrant trauma justifies distinct treatment and greater attention.

25 Gauge Vitrectomy

Purpose. Ocular trauma with retained foreign body is an important cause of visual impairment in working-age population. Clinical status impacts on the timing and planning of surgery. In the last year small gauge vitrectomy has become safer and more efficient, extending the range of pathologies successfully treated.Aims. To evaluate the safety and outcomes in patients with open eye injury with retained foreign body that underwent early 25-gauge vitrectomy.Methods. In this retrospective, noncomparative, interventional case series, we performed 25-gauge vitrectomy on 10 patients affected by open globe injuries with retained foreign body, over 3 years. We analyzed age, wound site, foreign body characteristics, ocular lesions correlated, relative afferent pupillary defect, visual acuity, and intraocular pressure. Follow-up evaluations were performed at 1, 3, and 6 months. According to the clinical status we performed other procedures to manage ocular correlated lesions.Results. The median age of patients was 37 years. The foreign body median size was 3.5 mm (size range, 1 to 10 mm). 25-gauge vitrectomy was performed within 12 hours of trauma. Foreign body removal occurred via a clear corneal or scleral tunnel incision or linear pars plana scleral access. Visual acuity improved in all patients. Endophthalmitis was never reported. Only two cases reported postoperative ocular hypertension resolved within the follow-up. Retinal detachment recurred in one case only.Conclusions. 25-gauge vitrectomy could be considered as early approach to manage open globe injuries with a retained posterior segment foreign body in selected cases with good outcomes and low complication rate.

To study the mechanism and clinical features of ocular injury and its outcome associated with bungee cord related eye trauma. A retrospective review of medical records was performed at our tertiary care centre to identify patients presented with bungee cord related eye injury between March 2016 to February 2017. Data collected from medical records were age, sex, mechanism of injury, clinical features, therapeutic intervention, presenting visual acuity, final visual acuity and length of follow up. Total of thirteen patients with bungee cord related trauma were identified. Ten (77%) patients presented with closed globe injury and 3(23%) presented with open globe injury. All patients were male with mean age group of 30.15±7.38 years. Presenting visual acuity ranges from 6/12 to NPL. Only seven (54%) of patients were having final visual acuity of better than or equal to 6/18 in injured eye. Three patients (23.1%) with open globe injury had final visual acuity of counting fingers or worse. Main mechanism of injury being combination of blunt and high speed projectile injury due to slippage of metal or plastic hook while the cord is stretched. Trauma with bungee cord is usually affecting working age group male with injury resulting in loss of workable vision to loss of eye hence there is need of appropriate intervention like use of printed warning on package and modification of hook design to decrease the incidence of bungee cord related trauma.

Feature Importance

AIM: To predict final visual acuity and analyze significant factors influencing open globe injury prognosis. METHODS: Prediction models were built using a supervised classification algorithm from Microsoft Azure Machine Learning Studio. The best algorithm was selected to analyze the predicted final visual acuity. We retrospectively reviewed the data of 171 patients with open globe injury who visited the Pusan National University Hospital between January 2010 and July 2020. We then applied cross-validation, the permutation feature importance method, and the synthetic minority over-sampling technique to enhance tool performance. RESULTS: The two-class boosted decision tree model showed the best predictive performance. The accuracy, precision, recall, F1 score, and area under the receiver operating characteristic curve were 0.925, 0.962, 0.833, 0.893, and 0.971, respectively. To increase the efficiency and efficacy of the prognostic tool, the top 14 features were finally selected using the permutation feature importance method: (listed in the order of importance) retinal detachment, location of laceration, initial visual acuity, iris damage, surgeon, past history, size of the scleral laceration, vitreous hemorrhage, trauma characteristics, age, corneal injury, primary diagnosis, wound location, and lid laceration. CONCLUSION: Here we devise a highly accurate model to predict the final visual acuity of patients with open globe injury. This tool is useful and easily accessible to doctors and patients, reducing the socioeconomic burden. With further multicenter verification using larger datasets and external validation, we expect this model to become useful worldwide.
