Intrabulbar, Intraorbital and Intracranial Perforating Eye Injury with Foreign Body: A Case Report

Ocular trauma is a significant cause of preventable blindness and visual impairment worldwide. Eye globe perforation can happen due to work with sharp tools or different particles that are spread during work with metals, wood, and other solid substances.We present the case of a 14-year-old male patient admitted as an urgent case at the Ophthalmology Department in 2014 due to a perforating eye injury with a foreign body – a 7 cm rusty metallic nail in the right eye. The X-ray of the orbit revealed that the foreign body had penetrated the eyelid, the eye eyeball, and through the orbit and its posterior wall, penetrated the skull and 2 cm in the brain. Under general anesthesia, we performed the anterior chamber lavage, excision of the prolapsed iris, and pupilloplasty. The anterior chamber was reconstructed using a saline solution (0.9% NaCl) and air. The patient was treated conservatively with antibiotics and steroids for 10 days; there were no signs of wound filtration, hypotonia, or endophthalmitis. Due to the limited resources for the posterior segment surgery, the patient was referred to another center for pars plana vitrectomy (PPV) after 10 days of hospitalization in the Department of Ophthalmology at the University Clinical Center of Kosovo. After PPV with silicon oil and cataract surgery, the patient could see the light and its projections (BCVA = L+P+). We followed up on the patient until September 2022, there were no signs of bulbus atrophy, and the visual acuity remained the same, BCVA = L+P+. The correct diagnosis and treatment at the right time play a leading role in achieving one of the main goals of surgical treatment of perforating eye injuries, which is the preservation of the anatomical structure and the physiology of the eye.

Использование аутологичной кондиционированной плазмы (аср) в хирургии тяжелой патологии заднего отрезка глаза. Трехлетний опыт использования технологии

Purpose. To evaluate the effectiveness and long-term results of the use of autologous conditioned plasma in the surgery of open eye injury, including perforating eye injuries, surgery of the cicatricial stage of the subretinal neovascular membrane, rhematogenous retinal detachment, including retinal detachment with macular hole in people with high myopia with expressed scleral staphyloma, without the use of an additional laser coagulation of the retina and the almost complete exclusion of silicone tamponade. Material and methods. Since 2018, more than 250 patients with various vitreous pathologies of the posterior eye segment have been operated on perforating eye injuries, cicatricial stage of the subretinal neovascular membrane, idiopathic macular rupture, rhegmatogenous retinal detachment, including those with macular holes, including cases with high myopia and expressed scleral staphyloma. The developed technology of surgical closure of defects of the retina, choroid, sclera of various lengths using autologous conditioned plasma, made it possible to completely eliminate the need for laser coagulation of the retina, which in most cases would be difficult and unsafe, and to practically exclude silicone tamponade. A method of seamless sealing of sclero and conjunctivotomies with the variant of air tamponade using autologous conditioned plasma has been developed and successfully applied. Results. In the early postoperative period the patients in all clinical groups had no complications. Complete adhesion of the retina and sealing of defects in the structures of the eye after using autologous conditioned plasma without additional laser coagulation of the retina on the background of the applied air and silicone tamponade was observed in all patients. In the long-term follow-up period up to 28 months, there were isolated recurrences of retinal detachment after surgery of complex open eye injury, rhematogenous retinal detachment on the background of progression of proliferative vitreoretinopathy. More than 89% of patients had no complications in the long-term period. Complete closure of the sclero and conjunctivotomies without the use of additional suture fixation had been achieved. In all cases, the vascular pattern of the conjunctiva was preserved, in no case was a reactive process detected at the site of application of autologous conditioned plasma. Conclusion. The use of autologous conditioned plasma is an effective and safe method of sealing defects of the retina, choroid, sclera of various lengths in complex open eye injury, of surgery of rhematogenous retinal detachment, including high myopia and the presence of a macular hole, of surgery of the cicatricial stage of the subretinal neovascular membrane, allowing to completely eliminate the need for laser coagulation of the retina, minimize the need for silicone tamponade.

Cause and Management of Suture-related Ocular Complications after Buried-suture Double-eyelid Blepharoplasty

Buried-suture double-eyelid blepharoplasty is very popular in Asia, especially in China, but there are few reports related to the cause, management, and prevention of suture-related complications of corneal injury and other damages to the eye. The study aims to determine the cause, management, and prevention of suture-related complications after buried-suture double-eyelid blepharoplasty. A retrospective study was conducted from January 2016 to January 2019 on 12 patients with corneal and other injuries to the eye after they underwent buried-suture double-eyelid blepharoplasty. The study included patients who underwent intermittent and continuous buried-suture double-eyelid blepharoplasty with the following symptoms: red eye, foreign body sensation, photophobia, pain, tears, and decreased vision. The clinical characteristics, examination method, and treatment were noted. The patients were all females. Ocular injuries included: corneal epithelial punctate or diffuse injury in nine patients, corneal ulcer in two patients, and a perforating eye injury in one patient. The corneal injury was repaired after exposed nylon thread ends were removed. A suture on the surface of the eye penetrating the sclera was detected in one patient, who then had a vitrectomy caused by endophthalmitis. Suture-removal surgery is indicated to treat suture-related complications. Less experienced clinicians should use an eyelid protection plate to protect the cornea and eyeball during surgery. The conjunctiva of the fornix should be examined after surgery. The clinician should inquire about the operation history in detail and check the conjunctiva of the fornix with an eyelid retractor to avoid misdiagnosis.

Investigation of the cause, anatomical localization of perforations and demographic characteristics in patients with perforating eye injuries

Aim: To investigate the clinical features of open globe injuries treated in our clinic.Material and Methods: 65 eyes of 65 patients who were operated for open globe injury between 2016-2018 in Pamukkale University ophthalmology clinic were retrospectively analyzed. File records; age, sex, injury with which eye was affected, the cause and type of injury, biomicroscopic examination findings were recorded. The type of injury was classified as corneal, scleral and cornea-scleral according to localization.Results: 65 eyes of 65 patients were included in this retrospective study. 65 of 30 eyes were right eye and 35 eyes were left eye. The mean age of the patients was 41.33 ± 23.52 years. 15 (23.0%) of the patients were under the age of 18 and 50 (67%) were adults. 23 (35.4%) women and 42 (64.6%) men were included in the study. The causes of eye trauma are shown in Table 1. 35 (53.8%) of the injuries were classified as blunt and 30 (46.2%) were classified as penetrating injuries.Conclusion: Open globe injuries, which is one of the most important causes of preventable blindness, is an important public health problem, we think that necessary precautions should be taken and public awareness should be taken in this direction.

Iris Cysts: Clinical Features, Imaging Findings, and Treatment Results

Objectives:To report the clinical and demographic characteristics, imaging findings, treatment results, and follow-up data of patients with iris cysts.Materials and Methods:The medical records of 37 patients with iris cysts were retrospectively analyzed. Ultrasound biomicroscopy (UBM), swept-source optical coherence tomography (SS-OCT), and SS-OCT angiography (SS-OCTA) were performed to examine the iris cysts.Results:The mean age of the patients was 34.4 years, ranging from 5 to 85 years. Twenty-four patients (65%) were female and 13 (35%) were male. Mean follow-up period was 21.3 months, ranging from 4 months to 8 years. Thirty-five (94.5%) of the cysts were classified as primary and 2 (4.5%) were classified as secondary. Thirty-one (83.7%) of the primary cysts were pigment epithelial and 4 were stromal. Primary iris pigment epithelial cysts were classified as peripheral in 26 patients (72.2%), midzonal in 4 (11.1%), and dislodged in 1 (2.7%). Stromal cysts were classified as acquired in 3 patients (8.1%) and congenital in 1 patient (2.7%). Secondary iris cysts were caused by perforating eye injury. UBM could visualize both the anterior and posterior surfaces of the cysts (26 patients). Anterior segment SSOCT could visualize the anterior but not the posterior surface of the cysts (4 patients). Iris cysts did not display intrinsic vascularity on SS-OCTA (4 patients). All pigment epithelial cysts were managed by observation. Of the 4 primary stromal cysts, 3 were managed by surgical excision and 1 by observation. Two secondary cysts required surgical removal.Conclusion:Pigment epithelial cysts generally remain stable without need for treatment. However, iris stromal cysts frequently require surgical intervention. UBM and SS-OCT were valuable in the diagnosis of iris cysts. On UBM, iris cysts appear with a thin, hyperechoic wall with hypoechoic internal content. Iris cysts did not have intrinsic vascularity on anterior segment SS-OCTA.

Analysis on the clinical characteristics and treatment of double perforation of eye ball

Objective To analyze the clinical characteristics and treatment of double perforation of eye ball. Methods The data of 41 eyes of 41 cases of double perforation of eye ball from Oct. 2011 to Jun. 2016 were analyzed retrospectively . The causes, injuries of the globe, and the entrance and exit wound were recorded and compared. The follow-up time was 6 months. Results The cases of double perforating eye injury occupied 1.07% of 3 832 cases of open-globe injury at the same period. The age ranged from 3 to 60 years, averagely (36.12±12.78) years. There were 35 males and 6 females. There were 17 cases in right eye and 24 cases in left eye. The cause of injury was metal foreign body in 32 cases (78.05%), steel wire stabing in 3 cases, air-gun ball in 2 cases and other causes in 4 cases. Six cases received enucleation, the other 35 cases received secondary surgery for reconstruction of the globe. The postoperative BCVA was improved (χ2=17.277, P=0.001). The postoperative BCVA in the group of the entrance wound length 2 DD group (χ2=14.221, P=0.003). Conclusion Double perforation of eye ball is a kind of severe eye injury. But the globe could be reconstructed and useful visual acuity could be restored if treatment was done properly and promptly. Key words: Doublepenetration, eye ball; Trauma, ocular, open; Surgery

Safety of Silicone Oil Removal in Cases of Gunshot Perforating Eye Injuries.

To evaluate the feasibility and safety of silicone oil (SO) removal in cases of gunshot perforating eye injuries (PEI). A retrospective, consecutive, interventional study from medical records regarding cases of gunshot PEI during the periods of Egyptian political instability (January 2011 until December 2013). The main outcomes were to evaluate the feasibility of SO removal in cases of gunshot PEI and management of retinal detachment (RD) after SO removal in such cases. One hundred ninety-six eyes of 193 patients were reviewed. SO was removed in 72 eyes of 70 patients (36.7%). After SO removal, five eyes (6.9%) developed RD. One case refused any other intervention. RD in the remaining four cases was treated with revision surgery and SO reinjection. The retina remained stable throughout follow-up. None of the eyes developed phthisis bulbi after SO removal. Mean follow-up after SO removal was 10.86 months (range: 3 months to 30 months). Mean follow-up after management of RD after SO removal was 17.7 months (range: 13 months to 21 months). Patients aged younger than 20 years were associated with extensive fibrous proliferation, which might affect the safety profile of SO removal in cases of gunshot PEI. Rate of RD after SO removal in cases of apparent retinal stability and localized fibrous proliferation was 6.9%. Retinal detachment after SO removal in such cases can be treated with revision surgery and SO reinjection. [Ophthalmic Surg Lasers Imaging Retina. 2017;48:242-250.].

The clinical significance of the changes of Th subgroup cytokines in patients with ocular trauma

Objective To investigate the clinical significance of the changes of Th subgroup cytokines in ocular traumatic patients. Methods The study objects include 30 eyes of 30 cases with ocular trauma. The patients were divided into group 1 (nonperforating eye injury) and group 2 (perforating eye injury) with 15 eyes of 15 cases in each group. And 15 healthy persons were enrolled as the control group. The dynamic changes of the concentration of serum cytokines IL-2, IFN-γ, IL-10, IL-17 were detected by ELISA. The results were compared among the three groups. Results In group 1, the concentration of IL-2 was higher than that in control group at early injury period, the difference was statistically significant (P<0.05); and the concentration of IFN-γ and IL-17 were lower than the control group, the difference was statistically significant (P<0.05). In group 2, IFN-γ and IL-17 decreased comparing with the control group, but the IL-2 and IL-10 increased (P<0.05). After treatment, all 5 cytokines in group 1 were decreased (P<0.05). Except for IL-17, the rest cytokines in group 2 decreased(P<0.05). Conclusion The dynamic changes of Th subgroup cytokines in ocular traumatic patients is closely related to disease progression.It can be an alterative inspection item for checking the validate of the anti-infection treatment.After anti-infection treatment, the secretion of Th1, Th17 decreased, the proliferation of white blood cells droped, which is benefit for reducing the risk of sympathetic ophthalmia.

Sympathetic ophthalmitis: A rare case presentation

Sympathetic Ophthalmitis is a rare, granulomatous uveitis occurring after perforating eye injury or ocular surgical procedure to one eye. The pathophysiologyis not clearly understood. We report a rare case of sympathetic ophthalmitis that presented to us in our hospital.Journal of Kathmandu Medical College, Vol. 4, No. 2, Issue 12, Apr.-Jun., 2015 page: 65-67

Timing of Pars Plana Vitrectomy in Management of Gunshot Perforating Eye Injury: Observational Study

The aim of this study is to report the difference in either anatomical or functional outcome of vitreoretinal intervention in cases of gunshot perforating eye injury if done 2–4 weeks or after the 4th week after the original trauma. Patients were treated with pars plana vitrectomy and silicon oil. Surgeries were performed in the period from February 2011 until the end of December 2014. 253 eyes of 237 patients were reviewed. 46 eyes were excluded. 207 eyes of 197 patients were analyzed. The included eyes were classified based on the timing of vitrectomy in relation to the initial trauma into two groups: 149 eyes (the first group) operated on between the 3rd and the 4th week and 58 eyes (the second group) operated on after the 4th week after the trauma. Following one surgical intervention, in the first group, attached retina was achieved in 93.28% of patients. In the second group, attached retina was achieved in 96.55% of patients. All RD cases could be attached by a second surgery. Visual acuity improved in 81.21% of patients, did not change in 15.43% of patients, and declined in 3.35% of patients. In the second group, visual acuity improved in 81.03% of patients, did not change in 12.06% of patients, and worsened in 6.89% of patients. There was no statistically significant difference between the two groups in either anatomical or functional results. We recommend interfering before the 5th week after the trauma as retinal detachment is encountered more in cases operated on after the 4th week. The visual outcome depends on the site of entry and exit (the route of gunshot).

Posttraumatic endophthalmitis : Complication following severe eye injury

Posttraumatic endophthalmitis is a rare but another extremely threatening complication for quality of vision, which has already been compromised by the trauma after perforating eye injuries. One of the substantial difficulties is the distinction between posttraumatic inflammation and development of a bacterial infection. In a hospital-based study 149 consecutive cases of perforating ocular trauma with open injuries to the eye within a 5-year period were retrospectively investigated. The study included assessment of the relationship between the severity of the injury and the risk of posttraumatic endophthalmitis using the ocular trauma score (OTS), the diagnosis, the therapeutic management and the prognosis concerning visual outcome 1 year after the posttraumatic endophthalmitis. In this study posttraumatic endophthalmitis was observed in 8 out of 149 cases (5.4 %) after perforating ocular injuries. Severe injuries had a higher risk of this complication. In comparison to the clinical courses of non-postraumatic endophthalmitis, the visual outcome showed a tendency to be worse after an average of 18 ± 6 months (1.25 vs 1.0 logMAR). In all of the cases the posttraumatic endophthalmitis could be successfully treated with antibiotics and surgery and the already severely limited visual function due to the injury could at least be maintained in most cases. Due to the low case numbers statistical evidence of a clear benefit of treatment by a rapidly initiated and intensive individualized surgery following trauma and a pathogen-specific and operative therapy is not possible: nevertheless, such a comprehensive therapeutic approach to posttraumatic endophthalmitis is recommended.

Wound-related complications and clinical outcomes following open globe injury repair.

Careful surgical management of traumatic wounds is important in open globe injury repair. This study examines the clinical outcomes following repair of open globe injuries with particular focus on wound-related issues. Retrospective, cohort study of consecutive open globe injuries presenting to a tertiary referral eye hospital from 1 January 2009 to 31 December 2011. A total of 267 eyes of 263 patients, mainly male (82.5%) with a mean age of 44.8 (range: 4-97) years. Average follow up was 6.9 months. All cases classified according to Ocular Trauma Classification Group. Visual outcomes, risk factors for and rates of postoperative complications and endophthalmitis. There were 83 globe ruptures, 182 penetrating and 2 perforating eye injuries, of which 43 cases had intraocular foreign body. Factors contributing to final visual acuity (VA) <6/60 were poor presenting VA (odds ratio [OR] = 16.0, 95% confidence interval [CI]: 4.81-53.1), globe rupture (OR = 4.64, [1.99-10.8]), retinal detachment (OR = 3.40, [1.19-9.74]) and age ≥50 (OR = 2.45, [1.05-5.74]). Wound leak occurred in 44 eyes (16%). Of these, 18 (41%) proceeded to re-suturing. Factors contributing to wound leak were stellate-shaped wound (OR = 3.28, [1.39-7.73]) and delayed presentation (OR = 2.80, [1.02-7.71]). Ten eyes (3.7%) developed endophthalmitis. Factors associated with endophthalmitis were delayed presentation (OR = 8.91, [1.71-46.6]), microbial keratitis (OR = 12.5, [1.85-85.0]) and lens capsule breach (OR = 12.4, [1.85-83.1]). Wound leak is an important postoperative complication of open globe injury repair. Delayed presentation is an important risk factor for postoperative wound leak and endophthalmitis. Prompt and meticulous wound management of open globe injury may reduce these complications.

Outcome of Vitrectomy and Chorioretinectomy in Perforating Eye Injuries

Purpose: To evaluate the anatomical and functional results of patients who underwent pars plana vitrectomy for perforating eye injuries as well as to analyze the benefit of the chorioretinectomy procedure. Methods: Retrospective and descriptive study of 24 eyes of 22 patients with perforating eye injuries operated on at the Centro Hospitalar do Porto between January 2006 and December 2012. Results: An early vitrectomy was accomplished in 67% of the eyes and a delayed vitrectomy in 33% of the eyes. A concomitant chorioretinectomy was carried out in 78%. Final proliferative vitreoretinopathy (PVR) was found in 11%. The anatomical success was 83%. At the final follow-up, 78% had best-corrected visual acuity equal to or superior to 5/200. Of the eyes that underwent early vitrectomy, 58% regained a visual acuity of 40/200 or better, versus 17% of the cases that underwent delayed vitrectomy. Conclusion: Early vitrectomy with prophylactic chorioretinectomy seems to be an effective approach to prevent PVR and improve the visual outcome and globe survival in perforating injuries.

Recurrent sympathetic ophthalmitis

Sympathetic ophthalmitis (SO) is a rare, bilateral granulomatous uveitis occurring after perforating eye injury or ocular surgical procedure to one eye. The pathophysiology of this entity is not clearly understood, but an autoimmune hypersensitivity reaction against exposed ocular antigens in the injured eye is believed to be responsible for this disease. In this article, we present a patient with clinical diagnosis of SO with it recurrence.

Chorioretinectomy for perforating eye injuries

To report the outcomes of chorioretinectomy in severe ocular injuries where a foreign body penetrated the choroid or perforated the globe. The study sample consisted of a retrospective, non-comparative, consecutive interventional case series of 13 perforating or severe intraocular foreign body ocular injuries that were treated at a single institution from March 2008 to March 2010. All the patients were operated with 20-gauge three-port pars plana vitrectomy (PPV) by removing the choroid and/or retina with scar tissue at the perforation site of the foreign body. The reports of patients were examined for best-corrected visual acuity, globe survival, retinal detachment status, and proliferative vitreoretinopathy. A total of 13 eyes of 13 patients with a mean age of 25.8 ± 9.0 years (range, 11-38 years) were followed for a median of 13.8 ± 5.4 months (range, 8-29 months). The mean time period between injury and the vitreoretinal surgery was 13.6 ± 9.3 days. All had an exit/impact site wound, eight of which were located in the posterior pole, which caused choroidal and retinal incarceration in the macular area. PPV together with chorioretinectomy, endolaser applications, silicone oil tamponade, with/without encircling band, and lensectomy surgery was applied to all of them. Final best-corrected visual acuity (BCVA) ≥20/200 occurred in 4 of 13 (30.76%) patients. Globe survival rates were 100% (13 of 13), and final retinal attachment rate was 84.6% (11 of 13). The proliferative vitreoretinopathy rate was 2 of 13 (15.3%). Chorioretinectomy is a surgical option that may decrease post-traumatic proliferative vitreoretinopathy and tractional retinal detachment rates, thus improving final BCVA and increasing globe survival rates when a foreign body penetrates the choroid and perforates the globe.

Combination Surgery for Management of Perforating Eye Injury With Retained Magnetic Intraorbital Foreign Body

The objective of this study was to evaluate the feasibility and safety of vitrectomy combined with magnetic intraorbital foreign body (IOrFB) removal in the patients with perforating eye injury and retained magnetic IOrFBs. A consecutive series of 7 patients with perforating eye injury and retained magnetic IOrFBs were included to perform secondary combination surgery (vitrectomy combined with IOrFB removal) after primary repair. Clinical data such as age, sex, hours and cause of injury, site and size of penetrating wound and IOrFB, involved intraocular tissues, surgical intervention, interval between surgeries, length of follow-up, anatomic recovery, visual outcome, and so on were recorded. Except for an unsuccessful IOrFB removal in case 6 in which IOrFB was finally extracted after 3 months, the remaining 6 cases had been operated on successfully both in vitrectomy and IOrFB removal. All the cases resulted in not only anatomic recovery but also good visual outcomes. No complications occurred. Seven cases revealed flat retina after silicone oil removal at a 3- to 12-month follow-up. Final best correct visual acuity equal to or better than 0.05 and 0.2 were 6 (85.7%) and 4 (57%) cases, respectively, and only 1 case was without improvement because of macular involvement. A combination surgery of vitrectomy with IOrFB removal is a highly efficient and safe procedure for the management of perforating eye injury with magnetic IOrFB. Prompt and proper management, such as preoperative exact localization of IOrFB, thoroughly cleaning of vitreous hemorrhage, complete sealing of retinal hole, and so on, is crucial for the successful achievement.

Ipsilateral Rotational Autokeratoplasty for the Management of Traumatic Corneal Scar

A 40-years-old male patient with a corneal scar secondary to perforating eye injury had undergone ipsilateral rotational autokeratoplasty in our clinics. The corneal scar involved the pupillary area. The patient had a preoperative visual acuity of counting fingers. The patient's cornea was trephined with a 0.5 mm temporal decentration. The 8.0 mm autograft was rotated approximately 180° to relocate the scar to the temporal aspect of the cornea. The final position of the corneal scar was temporal of the visual axis and central area was clear. The visual acuity at 1-, 3-, and 6-months followups was better than the first visual acuity in the patient. Ipsilateral rotational autokeratoplasty has many advantages over conventional keratoplasty. There is no risk of immunological rejection of the graft, postoperative corticosteroids are not needed as frequently, and donor cornea is not required. A rotational autograft can be a powerful alternative to conventional keratoplasty for some patients with traumatic corneal scars.

Perfluoroctano em cavidade orbitária após vitrectomia posterior e sutura de perfurante ocular: relato de caso

A case of a perfluoro-n-octane leakage into the orbital cavity after corneoscleral suture, scleral buckling and pars plana vitrectomy in an eye with perforating injury after trauma is reported for the first time. A previously healthy 39-year-old man was sent for ophthalmic evaluation one day after suffering a penetrating ocular trauma in his right eye while hammering a nail. On the initial evaluation, the patient presented sudden reduction of visual acuity on his right eye with a perforating corneoscleral injury, intraocular foreign body and retinal detachment. The patient was submitted to corneoscleral suture, pars plana vitrectomy with perfluoro-n-octane administration to flatten the retina and scleral buckling, when it was found transfixation of the globe by the intraocular foreign body. Postoperatively, computed tomography scans of the orbit were ordered due to proptosis, which showed the presence of hyperdense images, suggesting leakage of perfluoro-n-octane into the orbital cavity. Thus, in cases of perforating eye injury, one should be suspicious about the possibility of intraocular foreign body, as well as possible occurrence of transfixation of the globe when scheduling the surgery.

The role of B-scan ultrasound in diagnosis of penetrating ocular injury

Objective To assess the value of the B-scan on imaging of middle and posterior segment of eyeball,and intraorbitai lesion in patients with perforating ocular injury.Methods 129 patients(1 29 eyes)with perforating ocular injury underwent B-scan.We observed the B-scan echography images of vitreous cavity and retmbulbar space.Results The cause of the injury were sharp instrument injury,tiny foreign body shot,blunt trauma,explosion injury and unknown cause respectively.Lightly vitreous opacity without other obvious damage was found in 73 patients(56.59%),simple vitreous hemorrhage was found in 12 patients(9.30%),intraorbital foreign body Was found in 25 patients(19.38%),vitreous hemorrhage combined choroid detachment in 6 patients(4.65%),vitreous hemorrhage combined retinal detachment in 6 patients(4.65%),vitreous hemorrhge combined choroid detachment and retinal detachment in 7 patients(5.43%).Conclusion B-scan eehogmphy plays an important role in detecting intraocular and retmbulbar lesions of patients with ocular trauma,which is of particular value when the refracting media are opacified by traumatic iridocyclitis,traumatic cataract and haemorrhage. Key words: B-scan ultrasound; perforating eye injury; corneoscleral perforating injury
