A 45-year-old male presented with a slowly progressive, painless swelling in his right eye for the past 6 months. He had undergone an open globe injury repair 10 years back and an eventful cataract surgery 5 years back. The presenting visual acuity in the affected eye was perception of light with inaccurate projection of rays. The intraocular pressure was 44 mm Hg with advanced glaucomatous cupping. The swelling was identified to be a communicating sub-tenon cyst secondary to scleral wound dehiscence from secondary angle closure glaucoma. Wound re-suturing, cyst excision and diode laser cyclophotocoagulation was performed in a single sitting, with explained poor visual prognosis.

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.

Background: To investigate epidemiology, etiology, and outcomes after repair of pediatric open-globe injury. Methods: We retrospectively reviewed medical records of patients ⩽18 years who underwent primary open-globe repair. Results: A total of 213 patients were identified. Male–female ratio was 1.44:1. Type of injury was penetration in 157 (74.4%) cases, rupture in 52 (24.4%) cases, and perforation in 2 (0.9%) cases. Knife injuries were the most common cause, affecting 38/196 (19.4%), followed by metallic object in 37/196 (18.9%) patients, glass in 26/196 (13.3%) patients, and pen or pencil in 24/196 (12.8%). Predictors of good visual outcome defined as (⩾20/40) were good initial visual acuity (⩾20/40; p < 0.0001), time from injury to arrival at the emergency room >24 h (p = 0.038), size of wound less than 10 mm (p < 0.0001), absence of iris prolapse (p < 0.0001), deep anterior chamber at presentation (p < 0.0001), absence of hyphema (p = 0.043), intact lens (p < 0.0001), and no retinal detachment during follow-up (p < 0.0001). A total of 27 (12.7%) cases were documented to have retinal detachment at any time during follow-up period. Predictors of retinal detachment were perforation and rupture (p < 0.0001), whereas penetration was not associated with development of retinal detachment, size of the wound ⩾10 mm (p < 0.0001), initial visual acuity ⩽20/200 (p < 0.0001), lens injury (p < 0.0001), and development of endophthalmitis (p < 0.027). Eight (3.7%) eyes had the clinical diagnosis of posttraumatic endophthalmitis. Conclusions: The most common type of injury was penetration and the most common tool was knife. Visual outcome was affected by the initial presentation. Retinal detachment was a significant predictor of a worse final visual outcome.

Open Globe Injuries

AIM: To investigate the patterns and outcomes of open globe injuries in the elderly population in Iran. METHODS: In this retrospective cross-sectional chart review, medical records of 248 patients (aged 60y and more) with the diagnosis of open globe injury from 2006 to 2016 were reviewed. Demographic features, type, and mechanism of open globe injury, ocular trauma score (OTS), visual acuity before and after treatment, the zone of injuries, and the associated injuries found at the presentation or thereafter were documented. RESULTS: A total of 248 eyes of 248 patients were included. The mean age was 69.2±5.8y (range: 60-90y). Male/ female ratio was about 3:1 (187 vs 61). The three most common causes of injury were falling (25.2%), sharp objects (18.9%), and tree branches (13.9%). Penetrating injury accounted for most of the geriatric ocular trauma (50.4%), followed by globe rupture (40.3%), intraocular foreign body (IOFB; 7.3%), and perforating injury (2.0%). The median raw OTS for the population was 60.5 and the most common OTS class was 3. The injuries tend to affect zone I more than zone II and zone III. The only predictor of final visual acuity was the class of OTS (P<0.001). CONCLUSION: Geriatric open globe injury should be valued specifically. The most common type of open globe injury in Iran is penetrating injuries but falling remain the main cause. The OTS class must be considered as an important predictor of final visual acuity.

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.

Purpose To evaluate the safety and efficacy of secondary sulcus-fixed foldable intraocular lens (IOL) implantation through a clear corneal incision with 25-G infusion in patients with previous pars plana vitrectomy (PPV) after open-globe injury, and to analyze postoperative outcomes and prognostic factors of treatment. Methods Clinical data of 89 eyes of 89 patients with open-globe injury who underwent secondary sulcus-fixed foldable IOL implantation through a clear corneal incision with 25-G infusion after vitrectomy in our hospital between January 2008 and June 2015 were retrospectively analyzed. The examinations before IOL implantation mainly included visual acuity, slit-lamp examination, direct and indirect ophthalmoscope, visual electrophysiology, corneal endothelium, B scan, ultrasound biomicroscope, and intraocular pressure. Five eyes underwent suturing of peripheral iris and 7 eyes underwent suturing of iris laceration simultaneously. The mean follow-up was 18 months with a range from 6 months to 8 years. Results The mean interval between secondary sulcus-fixed foldable IOL implantation and vitrectomy was 2.8 months with a range from 2 to 6 months. The uncorrected visual acuity improved in all patients with a well-centered IOL ranging from 0.1 to 0.8 with the best-corrected visual acuity from 0.1 to 1.0 after secondary IOL implantation. The postoperative complications mainly included mild anterior chamber exudates in 10 eyes (11%), temporary IOP elevation in 12 eyes (13%), and recurrent retinal detachment in 5 eyes (6%), which were subsequently managed by surgery. Conclusions The interval of 2.8 months between vitrectomy and secondary IOL implantation is an appropriate and safe option to correct aphakia in patients receiving vitrectomy for open-globe injury.

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.
