Efficacy of Foldable Capsular Vitreous Body Implants Filled With Light or Heavy Silicone Oil in the Treatment of Silicone Oil-dependent Eyes.

The purpose of this study was to compare the clinical efficacy of foldable capsular vitreous body (FCVB) filled with either light or heavy silicone oil and the incidence of complications after their implantation for the treatment of severe ocular trauma and silicone oil-dependent eyes. FCVB filled with either light (n = 16) or heavy (n = 8) silicone oil was implanted in 24 patients. During the 12-month follow-up period, the intraocular pressure, final best-corrected visual acuity, retinal reattachment condition, position of the FCVB, and complications were assessed. All surgeries were performed without issue. There was no significant difference in preoperative and postoperative best-corrected visual acuity between the two groups. A significant improvement in the intraocular pressure was observed after surgery in both the light silicone oil (P = 0.029) and heavy silicone oil (P = 0.035) groups. None of the patients developed displacement or prolapse of the FCVB. The most common early and late postoperative complications were postoperative hemorrhage (33.3%) and corneal opacification (50%), respectively. FCVB filled with heavy silicone oil can be used as a supplemental therapy for patients who have lost the anterior segment of their eye, have lesions of the inferior retina, or cannot maintain the prone position for various reasons. Implantation of FCVB combined with heavy silicone oil compensates for the shortcomings of this with light silicone oil, providing patients with more personalized treatment.

Ocular fish hook injuries

PurposeFishing stands out as a widely enjoyed leisure pursuit. While ocular fishing injuries are infrequent, they carry the potential for severe ocular trauma, and safe extraction of a fish hook can pose challenges. We here in report a series of 21 cases of penetrating injury to the cornea by fish hook, detailing successful surgical interventions employed for their management. The report not only outlines different techniques for the removal of fish hooks but also provides clarification on terminologies associated with various components of a fish hook. MethodsThis was a retrospective study conducted at tertiary eye care centers in South India. Our hospitals cater to the states of Telangana, Andhra Pradesh, and Odisha. All medical records of patients who attended the emergency department from the period of 2003 to 2023 were evaluated and all patients with fish hook injury were included in the study. This is the longest and largest study in India. ResultsTwenty-one cases of ocular fish-hook injuries were presented to the emergency room between 2003 and 2023. Patients were between the ages of 9 and 59 years (mean, 29.4 years), and 90.4 % (19 out of 21) were males. Patient demographics, injury characteristics, surgical interventions, and visual outcomes were meticulously documented. Out of 21 cases, three cases (14.3 %) had blunt trauma, 17 cases (80.9 %) had penetrating injury and one case had lid laceration. Patients had better visual outcomes after the second surgery. Out of 21 cases, 7 (33.3 %) had post-operative visual acuity (VA) between 20/20 and 20/40. Three (14.3 %) had post-operative VA between 20/60 and 20/125. Five (23.8 %) had post-operative VA between 20/200 and 20/600. Six cases (28.6 %) had poor visual outcomes of which two had no perception of light (NPL), two had Hand movements and the other two had the perception of light present and projection of rays inaccurate ConclusionThis extensive case series underscores the complexity of ocular injuries caused by fish hooks and emphasizes significance of tailored surgical approaches for optimal visual outcomes. The hook can be successfully removed with minimal trauma to ocular structures by understanding structure of fish hook and by employing appropriate method of extraction.

Visual-functional impact of people affected by severe ocular trauma during social protests in Chile in 2019.

To determine the impact on the functionality associated with visual loss (VFIP) in people with severe ocular trauma (SOT) caused by kinetic impact projectiles used in police crowd control through a prioritization tool in people admitted to a rehabilitation program in Santiago de Chile from December 02, 2019, to November 13, 2020. Across-sectional descriptive study of SOT victims (N = 85), average age 31.4 ± 11.9. The data were recorded through a new 9-item screening instrument for assessment and prioritization of rehabilitation created for this emergency scenario. The impact of the use of kinetic weapons resulted in monocular blindness in the majority of those affected (n = 68; 80.0%). The highest VFIP observed was among young men from lower social strata. There were extreme difficulties in the performance of productive tasks (occupational and/or educational) (n = 42; 49.4%) and the pursuit of hobbies and pastimes (n = 23; 27.1%), as well as a high difficulty in adapting to changes in brightness (n = 29; 34.1%) and handling objects accurately (n = 22; 25.9%). The use of kinetic weapons for crowd control resulted in high and extreme VFIP and, in most cases, monocular blindness, causing major difficulties in work, study, and development of hobbies and pastimes in the affected population, highlighting the urgent need for effective rehabilitative care, which requires special attention in order to generate an adequate rehabilitation program. The use of kinetic weapons for crowd control contravenes international goals, policies, and plans set by the WHO and the International Agency for the Prevention of Blindness on strategies to prevent avoidable blindness worldwide until 2020. It is essential to ban the use of these weapons in Chile and worldwide, as well as to revise police protocols for crowd control.

Study on maintenance of eyeball morphology by foldable capsular vitreous body in severe ocular trauma

ObjectivesTo explore the feasibility and safety of using a foldable capsular vitreous body (FCVB) in managing severe ocular trauma and silicone oil-dependent eyes.MethodologyThis is a retrospective study of 61 ocular trauma patients (61 eyes) who presented to the Department of Eye Emergency, Hebei Eye Hospital from May 1, 2018, to May 31, 2019, including 51 male patients (51 eyes) and 10 female patients (10 eyes) with an average age of 44.98 ± 14.60 years old. The oldest patient was 75 years old, and the youngest was 8 years old. These cases represented 51 eyes with severe eyeball rupture and 10 eyes with severe, complicated ocular trauma, which became silicone oil-dependent after the operation. These patients received FCVB implants, and data regarding their visual acuity, intraocular pressure, changes in eye axis, cornea, retina, and FCVB state were recorded after the operation.ResultsIn all patients, the FCVB was properly positioned and well supported with the retina. All 61 patients cleared a follow-up window of 1–36 months with no reports of important changes in their visual acuity. Among the patients, 91.8% reported normal intraocular pressure, the retinal reattachment rate reached 100%, and the eyeball atrophy control rate reached 100%. There was no report of rupture of the FCVB, allergies to silicone, intraocular infection, intraocular hemorrhage, silicone oil emulsification, or sympathetic ophthalmia.ConclusionsFoldable capsular vitreous bodies (FCVBs) designed to mimic natural vitreous bodies are suitable as long-term ocular implants that can provide sustained support for the retina without the need for any special postoperative postures. Their barrier function may effectively prolong the retention time of the tamponade and prevent various complications caused by direct contact of the eye tissues with the tamponade.

Sustained Inhibition of VEGF and TNF-α Achieves Multi-Ocular Protection and Prevents Formation of Blood Vessels after Severe Ocular Trauma.

This study aimed to develop a clinically feasible and practical therapy for multi-ocular protection following ocular injury by using a thermosensitive drug delivery system (DDS) for sustained delivery of TNF-α and VEGF inhibitors to the eye. A thermosensitive, biodegradable hydrogel DDS (PLGA-PEG-PLGA triblock polymer) loaded with 0.7 mg of adalimumab and 1.4 mg of aflibercept was injected subconjunctivally into Dutch-belted pigmented rabbits after corneal alkali injury. Control rabbits received 2 mg of IgG-loaded DDS or 1.4 mg of aflibercept-loaded DDS. Animals were followed for 3 months and assessed for tolerability and prevention of corneal neovascularization (NV), improvement of corneal re-epithelialization, inhibition of retinal ganglion cell (RGC) and optic nerve axon loss, and inhibition of immune cell infiltration into the cornea. Drug-release kinetics was assessed in vivo using an aqueous humor protein analysis. A single subconjunctival administration of dual anti-TNF-α/anti-VEGF DDS achieved a sustained 3-month delivery of antibodies to the anterior chamber, iris, ciliary body, and retina. Administration after corneal alkali burn suppressed CD45+ immune cell infiltration into the cornea, completely inhibited cornea NV for 3 months, accelerated corneal re-epithelialization and wound healing, and prevented RGC and optic nerve axon loss at 3 months. In contrast, anti-VEGF alone or IgG DDS treatment led to persistent corneal epithelial defect (combined: <1%; anti-VEGF: 15%; IgG: 10%, of cornea area), increased infiltration of CD45+ immune cells into the cornea (combined: 28 ± 20; anti-VEGF: 730 ± 178; anti-IgG: 360 ± 186, cells/section), and significant loss of RGCs (combined: 2.7%; anti-VEGF: 63%; IgG: 45%) and optic nerve axons at 3 months. The aqueous humor protein analysis showed first-order release kinetics without adverse effects at the injection site. Concomitant inhibition of TNF-α and VEGF prevents corneal neovascularization and ameliorates subsequent irreversible damage to the retina and optic nerve after severe ocular injury. A single subconjunctival administration of this therapy, using a biodegradable, slow-release thermosensitive DDS, achieved the sustained elution of therapeutic levels of antibodies to all ocular tissues for 3 months. This therapeutic approach has the potential to dramatically improve the outcomes of severe ocular injuries in patients and improve the therapeutic outcomes in patients with retinal vascular diseases.

Chronic hypotony management using endoscopy-assisted vitrectomy after severe ocular trauma or vitrectomy.

To report outcomes of endoscopy-assisted vitrectomy (EAV) in patients with chronic hypotony following severe ocular trauma or vitrectomy. This was a retrospective, noncomparative case series. Ciliary bodies were evaluated using ultrasound biomicroscopy pre-operatively and direct visualisation intraoperatively. All selected individuals (seven patients/seven eyes) underwent EAV. Removal of ciliary membrane and traction, gas/silicone oil tamponade (GT/SOT), and scleral buckling (SB) were performed in selected eyes. Outcome measurements mainly included intraocular pressure (IOP) and best-corrected visual acuity (BCVA). Seven eyes from 7 male aphakic patients with a mean age of 45 (range, 20-68)y were included in this study; the average follow-up time was 12 (9-15)mo. GT was performed in 2 eyes; membrane peeling (MP) and SOT in 2 eyes; and MP, SOT, and SB in 3 eyes. The mean pre- and post-operative IOP were 4.5 (range, 4.0±0.11 to 4.8±0.2) mm Hg and 9.9 (range, 5.6±0.17 to 12.1±0.2) mm Hg at 52wk (12mo), respectively. BCVA improved in six eyes; one eye still showed light perception, and no bulbi phthisis was observed. Endoscopy offers improved judgment and recognition and has an improved prognosis for chronic hypotony. Therefore, endoscopy can be an effective and promising operative technique for chronic traumatic hypotony management.

Clinical efficacy of early vitrectomy in patients with severe blunt ocular trauma

BACKGROUND: Eye injury is an actual problem, occupying a leading position among the main causes of blindness and low vision, accounting for 22.8% in the structure of primary visual disability, of which 53% of cases are due to closed eye injury. Despite the development and widespread introduction into practice of methods of high-tech care for patients of this profile, there are a number of complications that poorly respond to treatment, ultimately leading to the loss of visual function of the injured eye.&#x0D; AIM: Evaluation of the effectiveness of early vitrectomy in patients with severe blunt ocular trauma, based on clinical results obtained during treatment and postoperative follow-up.&#x0D; MATERIALS AND METHODS: The study included 34 patients (34 eyes) with contusion-type eye injury. The mean age of patients was 39 years, among them 30 were men (88.24%) and 4 (11.76%) women. Patients were divided into 2 groups. Group 1 included 11 patients (10 men, 1 woman) with an open-type eye injury with a subconjunctival scleral rupture; upon admission, visual acuity varied from incorrect light projection to 0.01. In group 2, there were 23 patients (20 men, 3 women) with severe closed eye injury, upon admission to the hospital, visual acuity ranged from incorrect light projection to 0.06. In all cases, patients underwent subtotal three-port vitrectomy at an early date (up to 3 days) after injury.&#x0D; RESULTS: On the 1st day after surgery, there was an improvement in visual acuity in all patients. The follow-up period for patients was 6 months. All included patients had a stable anatomical result, no cases of subatrophy were noted, satisfactory functional results were achieved - visual acuity varied from 0.02 to 0.8. After 6 months, 32 out of 34 eyes (94.12%) showed no signs of proliferative vitreoretinopathy. In 2 patients (18.18%) from group 1, the development of proliferative vitreoretinopathy under silicone oil was revealed. Epiretinal membrane was diagnosed in 2 patients (8.7%) from group 2 and in 1 patient (9.09%) from group 1.&#x0D; CONCLUSIONS: Obtained clinical results of treatment of patients with severe blunt ocular trauma indicate the expediency of vitrectomy in early stages after injury, which is an effective treatment method. Long-term results demonstrate stable functional results for 6 months. Vitrectomy performed early after injury serves for prevention of proliferative vitreoretinopathy, but does not completely exclude its development. Performing surgery early after injury increases the prospects for preserving visual functions of the eye and is a positive prognostic factor.

Artificial iris: state of the art.

Surgical correction of traumatic aniridia aims to improve quality of vision, compartmentalize anterior and posterior chamber, re-establish a satisfying cosmetic appearance. Various types of prosthetic iris devices (PIDs) are available, that differ in technical difficulty of implant and design: artificial iris-intraocular lens (AI-IOL) prosthesis, endocapsular capsular tension ring based PID, and customized AI. The choice depends to the pre-existing clinical condition after severe ocular trauma and on patient's functional and cosmetic expectations. This systematic review of literature compared anatomical and functional outcomes of various types of PIDs. Of 185 articles found in literature, 70 fulfilled the eligibility criteria. 5 subgroups of PIDs were: Opthech, Artificial Iris from the Ophtec, Morcher, Humanoptics and 'other prosthesis'. Both glare and aesthetic outcome improved after surgery; in comparison to other PIDs, intraocular pressure (IOP) rise incidence was higher in the Morcher group (40%), whereas prosthesis dislocation incidence was higher in the Ophtech group (39%).

Ocular injury from foam dart (Nerf) blasters: a case series.

Foam dart blasters can cause severe blunt ocular trauma and permanent visual loss, illustrating the need for eye protection when handling these toys. • Foam dart blasters, a blanket term for spring-loaded toy guns that fire foam-coated darts or bullets at a relatively low velocity, have gained popularity in recent years among pediatric populations, with an increase in associated ocular injuries. •To date, scattered case reporting provides insufficient insight into the full clinical spectrum of injury and prognosis of foam dart blasters related ocular injury. •This case series characterizes the myriad foam dart blasters injuries that may afflict the eye, most of which are self-limiting, but some of which may result in poor visual outcomes and lifelong disability in pediatric patients. •We strongly recommend that all users wear eye protection while using foam dart blasters.

Clinical Application of Foldable Capsular Vitreous Bodies in the Treatment of Severe Ocular Trauma and Silicone Oil Dependent Eyes.

This study aimed to assess the application of a foldable capsular vitreous body (FCVB) in the treatment of severe ocular trauma and silicone oil (SO) dependent eyes. A retrospective analysis was performed on the clinical application of FCVB in the treatment of severe ocular trauma and SO dependent eyes. The results of best-corrected visual acuity and intraocular pressure (IOP) evaluation, B-scan ultrasonography or color Doppler ultrasonography, ultrasound biomicroscopy, and anterior segment photography were recorded during follow-up. A paired t-test was used to compare the difference in IOP before and after FCVB implantation. Seven eyes of seven patients were included in the 6-month follow-up. In all cases, B-scan ultrasonography and ultrasound biomicroscopy showed that FCVB adapted closely to the globe wall and ciliary body, thus supporting the retina. Visual acuity did not improve, except in one case from LP to HM. The mean ± SD IOP was 8.5 ± 1.90 mm·Hg prior to FCVB implantation and 10.43 ± 0.98 mm·Hg after implantation, with no significant difference between these measurements (P=0.095). Five of the seven patients developed differing degrees of corneal opacity and keratopathy. FCVB implantation may be a safe and effective method for the treatment of severe ocular trauma and SO dependent eyes. However, FCVB cannot prevent the phthisis of the traumatic eyes. In addition, corneal opacity and keratopathy are potentially serious complications after surgery. Appropriate case selection and proper surgical timing are required for further investigation.

The effect of silicone oil retention sutures on preventing silicone oil migration and protecting the corneal endothelium

Objective: To observe the restriction effect of silicone oil retention sutures and their protective effect on the corneal endothelium. Methods: Retrospective case series study. The clinical data of 6 patients (6 eyes) with lens-iris damage after severe ocular trauma were collected from March 2017 to November 2021 in Beijing Tongren Hospital. Their was combined retinal injury in each eye, so silicone oil retention sutures and silicone oil filling were performed. The silicone oil position was observed by slit lamp and ultrasound biomicroscopy. The corneal endothelium was examined by specular microscopy during the follow-up. Results: All patients were male, with an average age of 47 years (range, 26 to 73 years). The diseased eyes included 2 left eyes and 4 right eyes. Five eyes had ocular rupture, and 1 eye had ocular contusion. The follow-up time ranged from 5 months to 51 months, with an average of 18.5 months. In all 6 eyes, the silicone oil was completely located in the posterior segment and never touched the corneal endothelium. Four eyes maintained healthy and had a clear cornea during the follow-up, while 2 eyes developed band keratopathy at the 11 month and 16 month separately during follow-up, 1 of which was found to suffer corneal decompensation at the last follow-up (51 month). Both band keratopathy and corneal decompensation were caused by severe anterior segment trauma and were not related to the silicone oil contact with the cornea. There were no complaints about occlusion or glare due to silicone oil retention sutures. All patients did not need to keep the prone position postoperatively. Silicone oil emulsification occurred in 1 eye and ocular hypertension occurred in this eye after silicone oil emulsification. Conclusion: Silicone oil retention sutures can effectively prevent silicone oil from migrating to the anterior chamber or contacting the corneal endothelium.

Guideline for the treatment of no light perception eyes induced by mechanical ocular trauma.

Severe mechanical ocular trauma with no light perception (NLP) predicts a poor prognosis of visual acuity and enucleation of the eyeball. Since the innovative treatment concept of exploratory vitreoretinal surgery has developed and treatment technology has advanced, the outcomes of severe ocular trauma treatment in NLP patients have greatly improved. However, there remains a lack of unified standards for the determination, surgical indication, and timing of vitrectomy in NLP eye treatment. To address these problems, we aimed to create evidence-based medical guidelines for the diagnosis, treatment, and prognosis of mechanical ocular trauma with NLP. Sixteen relevant recommendations for mechanical ocular trauma with NLP were obtained, and a consensus was reached. Each recommendation was explained in detail to guide the treatment of mechanical ocular trauma associated with NLP.

Longitudinal assessment of the effect of alkali burns on corneal biomechanical properties using optical coherence elastography.

Eye injury due to alkali burn is a severe ocular trauma that can profoundly affect corneal structure and function, including its biomechanical properties. Here, we assess the changes in the mechanical behavior of mouse corneas in response to alkali-induced injury by conducting longitudinal measurements using optical coherence elastography (OCE). A non-contact air-coupled ultrasound transducer was used to induce elastic waves in control and alkali-injured mouse corneas in vivo, which were imaged with phase-sensitive optical coherence tomography. Corneal mechanical properties were estimated using a modified Rayleigh-Lamb wave model, and results show that Young's modulus of alkali-burned corneas were significantly greater than that of their healthy counterparts on days 7 (p=0.029) and 14 (p=0.026) after injury. These findings, together with the changes in the shear viscosity coefficient postburn, indicate that the mechanical properties of the alkali-burned cornea are significantly modulated during the wound healing process.

Recovery course of foveal microstructure in the nonsurgical resolution of full-thickness macular hole.

To analyze the recovery course of foveal microstructures in eyes with nonsurgical healing of full-thickness macular hole (FTMH). By serial OCT scans, the temporal healing sequences were analyzed in ocular trauma, vitreomacular traction (VMT), cystoid macular edema (CME), and the remaining group. We evaluated correlations between the final best-corrected spectacle visual acuity and reconstruction time of external limiting membrane (ELM), and inner segment/outer segment (IS/OS). The healing (mean±standard deviation in months) most involved fusion at the level of the outer nuclear layer (ONL) (6.3±10.5) followed by restoration of ELM (9.1±13.8), and lastly, by IS/OS regeneration (13.1±19.5). In severe blunt ocular trauma, healing was fast and involved subretinal zipper glue-like reapposition with resulting outer retinal atrophy. Best spectacle-corrected visual acuity correlated with normalization of the clivus (p=0.012), faster ELM (p=0.006), and IS/OS reconstitution (p=0.024). Recurrence of FTMH occurred when the healing was halted (3 eyes) or was aberrant by lamellar hole epiretinal proliferation (LHEP) (3 eyes) or by the persistence of VMT (1 eye). Recovery sequences proceeded from the ONL to the deeper layers with BCVA correlating absolutely and temporally with the restoration of outer retinal layer integrity.

FOLDABLE CAPSULAR VITREOUS BODY IMPLANTATION FOR COMPLICATED RETINAL DETACHMENT CAUSED BY SEVERE OCULAR TRAUMA.

To explore the effectiveness, safety and psychological impact of foldable capsular vitreous body (FCVB) implantation for complicated retinal detachment caused by severe ocular trauma. This was a prospective, single-arm, surgical interventional case series study. A standard 3-port 23-gauge pars plana vitrectomy was performed, and the FCVB was implanted into the vitreous cavity. Observed indicators, including the best-corrected visual acuity, intraocular pressure (IOP), retinal reattachment, complications, and patient satisfaction, were analyzed to evaluate the study. A total of 28 cases (eyes) were enrolled, with a mean follow-up of 16.93 ± 9.67 months and an average age of 51.11 ± 10.14 years, including 22 men (78.57%). The FCVB was successfully implanted, and the retina was reattached in all cases. The postoperative best-corrected visual acuity improved in 7 cases, and remained unchanged in 21 cases ( P > 0.05). The average IOP was 7.01 ± 2.43 mmHg before surgery and 8.54 ± 2.93 mmHg after surgery ( P < 0.05). Complications such as FCVB displacement, endophthalmitis, secondary glaucoma, silicone oil emulsification, and escape did not occur during the follow-up period. Patients with FCVB implantation are highly satisfied. Most patients feel hope, positive, and optimistic about life. Foldable capsular vitreous body implantation for complicated retinal detachment caused by severe ocular trauma is effective and safe, and it allows patients to face life positively and optimistically.

Evisceration Versus Enucleation in Ocular Globe Injury

Evisceration and enucleation have been acceptable therapeutic modalities to treat not only severe ocular trauma but also various ocular conditions, such as intraocular tumors, endophthalmitis, and blind-painful-cosmetically disfiguring eyes, over the last two centuries. Clinical indications and choices of procedure, whether enucleation or evisceration, vary among institutions, surgeon experience, and severity of structure loss. In the past, enucleation has been preferred by most surgeons for various reasons, including the fear of sympathetic ophthalmia (SO) after evisceration. Despite the possibility of causing SO, anophthalmic socket also has complications, including superior sulcus defect, conjunctival surface changes, implant exposure, fornix/socket contraction, and eyelid malposition. This literature review will discuss indication, technique, and decision with regard to enucleation or evisceration after ocular trauma.

Sensorimotor Outcomes in Pediatric Patients With Ocular Trauma in Baltimore.

To evaluate sensorimotor outcomes following traumatic open globe injuries in the pediatric population. A retrospective cohort of 80 pediatric patients aged 0.4 to 17.7 years (mean age: 9.3 years, median age: 8.3 years) presenting with traumatic open globe injury to the Johns Hopkins and University of Maryland Medical Centers was evaluated between January 2006 and January 2020. Parameters included the mechanism of injury, length of time of visual deprivation, initial and final visual acuity, additional eye pathologies, and demographic factors such as age and sex. Among children with more than 6 months of follow-up, 77.4% developed poor stereopsis and 50% developed strabismus. Children who developed strabismus had a lower Pediatric Ocular Trauma Score (POTS), indicating greater severity of injury, than children who did not develop strabismus (P = .005, chi-square test). A higher POTS, indicating less severe ocular injury, significantly correlated to a better stereoacuity (P = .001, chi-square test). The findings indicate that strabismus and poor stereopsis are common in pediatric open globe injuries, occurring in more than half of children with pediatric open globe trauma. These outcomes are associated with poor presenting visual acuity, more severe ocular trauma, and a lower presenting POTS. [J Pediatr Ophthalmol & Strabismus. 2022;59(5):303-309.].

Globe Ruptures: Outcomes and Prognostic Analysis of Severe Ocular Trauma

Purpose: Eye trauma is an important cause of monocular visual loss worldwide. This study aimed to describe the structural and functional characteristics and outcomes of 281 globe ruptures. Methods: Medical records of all patients undergoing surgery for a ruptured globe at Centro Hospitalar Universitário do Porto in the last 17 years were retrospectively reviewed. Results: 281 eyes of 277 patients were included. The majority of them were males (71%) with a mean age of 59.7 ± 20.5. In 38.8% of the cases, the cause was a fall. At the time of admission, 29.5% of the eyes had a visual acuity (VA) greater than 20/200 and 12.5% had no light perception. The median time between trauma and primary repair was less than 8 h (interquartile range 5–12 h). A primary reconstruction was always attempted. Primary evisceration was performed in 14 cases (5%). In multivariable analysis, independent predictors of vision survival were male gender, shorter wound size, and absence of vitreous hemorrhage. Conclusion: In this large, retrospective study on globe ruptures, we identified male gender, short wound length, and the absence of vitreous hemorrhage or retinal detachment as predictors of improved functional outcome. We found a correlation between the presenting and final VAs. The Ocular Trauma Score predicted the outcome well. Our determination to reconstruct the traumatized eyes as early and as completely as possible was justified by the functional results: despite the severity of the injuries, one out of four eyes reached a final VA greater than 20/200.

Clinical characteristics and functional outcome of pediatric ocular trauma in a third level reference hospital in Guadalajara, Mexico.

Ocular trauma is one of the leading causes of decreased visual acuity and monocular blindness in the pediatric population. Since its occurrence is potentially preventable, it is essential to understand its demographic characteristics and risk factors to alert and implement prevention and health promotion programs. We conducted a retrospective study in which we reviewed 187 clinical records of patients ≤ 15 years old with the diagnosis of severe ocular trauma admitted in 2017 to the Hospital Civil de Guadalajara. We analyzed demographic variables, circumstances of the event, type of treatment, and the evolution of visual acuity and complications. In total, 187 patients and 188 eyes were included; the average age was 6.99 ± 4.1 years. Children of 2 to 5 years of age (41%) were the most affected, and a higher occurrence was observed in males (73%). Open ocular trauma was the most common type of injury (72.7%) caused by sharp objects (45.4%). Most injuries occurred at home (78.1%), without adult supervision (48.1%), and during leisure time (74.9%). Most events were accidental (80.4%), although 12.3% were direct aggression. Surgery was required in 179 patients, in whom corneal injury repair (43.2%) was the most commonly used procedure. Final visual acuity was quantified in 132 eyes, and visual acuity < 20/200 was found in 18.1%. Loss of 4.2% of the eyeballs was recorded. The highest proportion of cases was identified in male patients ≤5 years old, unsupervised by an adult. Many eye injuries are preventable, so it is necessary to implement socio-educational programs in alliance with pediatric organizations that alert the severity of the problem and promote safe environments.
