Introduction: Corneal foreign bodies account for nearly one-third of all eye injuries and are a common emergency in ophthalmology. While many cases are straightforward, involving clear diagnosis and treatment, some present significant challenges due to the complexity of the foreign body involved., Observation: A 20-year-old male presented with discomfort in his right eye following an accident while cutting a tree without wearing protective eyewear. Examination using slit-lamp biomicroscopy revealed a reed foreign body embedded in the cornea. Anterior Segment Optical Coherence Tomography (AS-OCT) provided detailed images, showing the foreign body embedded 300 µm beneath the corneal epithelium but not affecting deeper layers. The foreign body was surgically removed under topical anesthesia, followed by thorough cleansing and suturing of the wound., Conclusion: AS-OCT is invaluable in the diagnosis and management of complex corneal foreign bodies, enabling precise treatment planning and successful outcomes, as demonstrated in this case.

Purpose: To determine corneal foreign body (FB) location together with corneal wound depth and width by using anterior segment optical coherence tomography (AS-OCT) after uncomplicated FB removal., Method: This prospective study was conducted with patients injured by a superficial metallic corneal FB. Under slit-lamp examination, after determining its location, the FB was removed with a 27-G needle. The depth and width of the corneal wound and the thinnest stromal thickness at the wound site were measured initially using AS-OCT. Measurements were repeated to assess the wound healing process at one week and at two months following FB removal., Results: Totally, 63 eyes of 63 patients were included in this study. The average age was 35.8 ± 11.0 years, and 96.8% of the patients were men. In terms of location of the FBs, 26 (41.3%) were in the central region, 21 (33.3%) were in the paracentral region, and 16 (25.4%) were in peripheral regions. The mean depth and width of the corneal wounds were 117.0 ± 42.5 µm and 332.9 ± 99.4 µm, respectively. The mean percentage of corneal wound depth was 18.9 ± 6.1%. In 20 patients who presented for follow-up, it was observed that the width of the wound increased and the thinnest stromal thickness at the wound site decreased over the two months., Conclusion: The AS-OCT findings of the present study showed that the corneal FBs generally affected the anterior cornea with less than approximately 0.2 mm depth and 0.5 mm width. In addition, FBs were commonly located in the central and paracentral cornea.

Purpose: Deeply embedded corneal foreign bodies and intrastromal foreign body removal can often be a challenge. The aim of this report was to describe the utility of endoscopy in visualization and removal of an embedded corneal bee stinger., Methods: A 44-year-old male patient developed toxic keratopathy after injury from a bee stinger. On examination, the bee stinger was noted to be deeply embedded in the corneal stroma. A superficial keratectomy was initially attempted; however, the stinger was noted to be intrastromal and protruding into the anterior chamber and could not be removed. An Endoscopy-assisted visualization was used to remove the stinger., Results: The bee stinger was successfully removed and the patient's vision improved to 20/100 from an initial CFCF (counting fingers close to face) at time of presentation. At the end of 3 months follow-up, there was residual corneal edema along with cataractous changes in the lens as a sequelae of the initial bee sting injury. The patient subsequently underwent an endothelial keratoplasty along with phacoemulsification with intraocular lens implantation and the final BCVA improved to 20/40., Conclusion: Endoscopyassisted visualisation of anterior chamber and angle structures can be valuable in removal of retained and deeply embedded corneal or intracameral foreign bodies., Competing Interests: None

Fishing is a worldwide pastime enjoyed by millions of people. Ocular fishing injuries though uncommon may cause potentially devastating ocular trauma. We report a rare case of penetrating injury of the cornea by a barbed fish hook and its successful surgical management by "cut-it out technique". We are discussing the various techniques available for removal of fish hooks. The hook can be successfully removed with minimal trauma to ocular structures by understanding the structure of the fish hook and by employing the appropriate method of extraction., Competing Interests: None

Purpose: Opiorphin is an endogenous inhibitor of enkephalin-degrading enzymes. It has a strong analgesic effect in chemical and mechanical pain models. We aimed to evaluate the tear opiorphin levels in ocular pain caused by corneal foreign bodies and demonstrate whether there is any correlation with pain levels obtained from the Visual Analog Scale (VAS) score and tear opiorphin level., Methods: Thirty-two healthy individuals and 34 individuals diagnosed with corneal foreign bodies were included in this study. Tear opiorphin levels were measured by the ELISA method using a commercially available kit. The difference in tear opiorphin levels between the patient and control groups were evaluated using the Mann-Whitney U test. The correlation between VAS scores and tear opiorphin levels was evaluated using the Spearman rank correlation coefficient., Results: The median values of tear opiorphin levels of the patient and control groups were 134 pg/mL (86.86-296.25) and 109.80 pg/mL (66.15-191.49), respectively. The Mann-Whitney U test showed a statistically significant difference in tear opiorphin levels between patient and control groups (P < 0.05). No ocular pain was reported in the control group. The median VAS score of the patient group was 6 points (1-9). No correlation was found between VAS scores and tear opiorphin levels in the patient group., Conclusions: The cornea is the most densely innervated tissue, and the highest opiorphin concentrations have been observed in tear. It is, therefore, expected that the stimulation or damage to the nerve endings in cornea would cause an increase in opiorphin secretion as a pain relief mechanism.

Purpose: To report an uncommon case in which an insect foreign body (FB) in the cornea induced severe marginal ulcerative keratitis., Methods: The insect body was removed during an eye examination. A shaped deep lamellar keratoplasty was then performed on the ulcerous corneal tissue and pseudopterygium. The insect FB was identified as a member of the nontoxic Diptera insect order, belonging to either the Chloropidae or Sphaeroceridae family., Results: The patient recovered well after the keratoplasty, and her corneal graft was clear with significantly improved visual acuity after 2 months., Conclusions: Long-time retention of a nontoxic insect FB in the cornea could induce severe noninfectious keratitis. Individually designed deep lamellar keratoplasty successfully restored the transparency of the cornea and visual function.

Firecracker induced open globe injury is a big challenge for ophthalmic surgeons. Its association with the intraocular foreign body makes the diagnosis and treatment even more difficult resulting in poor anatomical and visual outcomes. We report a case of a 35-year-old male who presented with bilateral, multiple corneal and intraocular foreign body due to firecracker explosion. His vision was limited to hand movement in both eyes. Combined penetrating keratoplasty and cataract surgery were done in both eyes followed by pars plana vitrectomy for intraocular foreign body removal. The final best-corrected visual acuity of the patient stood to be 6/6 and 6/9 in the right and left eye respectively. The encouraging result in our case prompts ophthalmologists for a timely stepwise multidisciplinary approach in all open globe injuries with intraocular foreign body cases having poor initial acuity.

Background: To report a case of lenticular infection caused by Aspergillus, which was diagnosed 13 weeks after traumatic corneal laceration., Case Presentation: A 60-year-old woman presented with traumatic corneal laceration including anterior lens capsule rupture and traumatic cataract after being hit with a chestnut in the right eye. There were multiple injuries due to tiny thorns of the chestnut, including the conjunctiva, sclera, cornea, and anterior lens capsule. But no visible foreign body was detected by slit-lamp examination. Topical corticosteroid was prescribed to resolve the conjunctival inflammation induced by the thorns of chestnut, which could have caused persistent irritation. As conjunctival injection and edema being decreased during outpatient clinical follow-up, embedded conjunctival foreign body was detected and surgically removed (1st surgery). Approximately 10 weeks after the trauma, severe inflammation of the anterior segment accompanied with hypopyon developed suddenly and at the same time embedded scleral foreign body was revealed. After removal of scleral foreign body (2nd surgery), unspecified mold species was cultured from the scleral foreign body in SDA (Sabouraud dextrose agar) plate. Suspicious corneal foreign body was removed as 3rd surgery and phacoemulsification of traumatic cataract was planned as 4th surgery. Aspergillus was finally detected from removed anterior capsule and fibrotic membrane during the operation. Fungal infection resolved successfully after administration of topical (1% voriconazole and 5% natamycin) and systemic (fluconazole) antifungal agents and phacoemulsification of traumatic cataract., Conclusion: Chestnut thorns can damage multiple ocular tissues simultaneously. Lens capsular rupture could result in fungal inoculation and lead to delayed lenticular fungal infection with complicated cataract formation. In cases of ocular trauma due to organic substances such as thorns and branches, the possibility of fungal infection should be considered.

Purpose: Corneal foreign bodies (CFBs) due to occupational exposure have been largely ignored in Indian literature, especially nonmetal workers. Our study looks at a broad range of occupations and settings that contribute to CFB in our local Indian population., The Study Objective Was to: determine the occupations, level of education and demographics of patients presenting with CFB acquired during occupational work., Methods: Prospective hospital-based study at a tertiary eye hospital in Gurgaon, Haryana, India, within duration of 9 months. Patients presenting with CFB were asked a set of questions relating to their occupation, level of education, understanding of the potential complications of CFB, and demographics., Results: A total of 83 patients were included in the study. CFB were attributed only to males. 66% of patients were in the age group of 14--29 years. 30% of patients were in the age group 30--44 years and 4% of patients were between 45 and 60 years old. The metal work industry was responsible for 47% of presentations. The construction industry was responsible for 27% of presentations. Electricians and carpenters combined were responsible for 10% of presentations and 17% of presentations occurred in other sectors., Conclusion: CFB occur across a number of occupations in the construction industry, not just metallic workers. Among a population that is generally poorly educated and have nominal understanding of the impact that CFB can have on vision, occupational hazard education is necessary to address this problem., Competing Interests: None

Purpose: The purpose of the study was to describe findings demonstrated by anterior segment spectral domain optical coherence tomography (AS-OCT) in various types of deeply embedded corneal foreign bodies., Methods: In this experimental study, an ex vivo model of calf eyes was used and seven different foreign bodies were deeply embedded in the cornea, consisting of five different materials: glass, plastic, metal, wood, and pencil graphite. The eyes were photographed and then scanned by AS-OCT. The images were analyzed to determine distinguishing characteristics for each material., Results: Various materials presented unique characteristics in AS-OCT. The opaque materials (pencil graphite, metals, and wood) demonstrated a hyper-reflective anterior border, whereas the posterior border signal could not be clearly identified due to the shadowing effect. Moreover, a chain of signals was characteristic of both pencil graphite and metals though a "mirroring effect" was unique for metals. Wood, as an opaque material, appears as a hyper-reflective mass with a spectrum of penetrability depending on the degree of concentration. Transparent materials demonstrated hyper-reflective sharp borders when surrounded by air or fluid, as opposed to when being embedded purely in the corneal stroma., Conclusions: This study shows that AS-OCT was used to systematically define a novel set of distinguishing characteristics specific to various materials extruding from the cornea, fully embedded in the cornea, and intruding into the anterior chamber. Hopefully, the described characteristics of each material can aid clinicians in diagnosing the type of the material embedded and the depth of its involvement in ocular injury.

Ru-ik Chee Felix Y. Chau In this case of a perforating eye injury by a 2-inch-long nail that went through the cornea, lens, and posterior eye wall, the authors describe a combined external, anterior, and posterior segment surgical approach that resulted in safe and successful removal of the foreign body. Initial external trimming of the protruding nail facilitated the use of a noncontact viewing system. Combined limbal and pars plana placement of the vitrectomy cannulas optimized access to both anterior and posterior intraocular structures. Most importantly, careful removal of potential sources of foreign body adhesion to intraocular structures prior to extraction likely increased the likelihood for a successful clinical outcome. Care was taken to remove as much of the vitreous as possible and to keep the eye formed. The patient recovered 20/25+2 vision with aphakic correction., (Copyright 2018, SLACK Incorporated.)

Significance: As the prevalence of post-laser-assisted in situ keratomileusis (LASIK) patients rises, recognition of possible traumatic complications and their management in this population becomes increasingly relevant. Penetrating injuries and intraocular foreign bodies are possible in post-LASIK corneas despite an intact anterior corneal surface. However, with prompt recognition and treatment, excellent visual recovery can be achieved., Purpose: The purpose of this study was to report an interesting case of a penetrating foreign body through an intact LASIK flap., Case Report: A 48-year-old man presented to an outside provider with right eye pain after his eye was struck by a tree branch. His ocular history was notable for uncomplicated LASIK surgery 4 years before presentation. On initial examination, the patient was diagnosed as having a small corneal abrasion and hyphema. Despite appropriate therapy, his eye continued to subjectively and objectively worsen. Follow-up examination after the injury was notable for a new dense hypopyon. Because of concern for secondary infection, the patient was referred urgently for further evaluation. Upon referral, the patient was noted to have a dense, fibrinous mass located inferiorly in the anterior chamber. Although the cornea was edematous temporally with deep folds, the anterior corneal surface appeared intact without evidence of laceration or flap displacement. Concern for endophthalmitis prompted anterior chamber washout, where a large vegetative foreign body was recovered despite an intact anterior corneal surface and LASIK. Post-operative anterior-segment optical coherence tomography after resolution of the corneal edema confirmed the presence of a well-aligned penetrating tract through the posterior stromal bed underneath the LASIK flap. Epithelial ingrowth that developed within the post-operative period further affirmed the initial tract of the penetrating foreign body., Conclusions: This case illustrates a novel complication after trauma in a post-LASIK patient, describes possible management, and underscores the care that must be taken when assessing patients with a history of LASIK surgery.

Purpose: To compare the outcomes of ocular injuries of hornets and paper wasps' stings., Study Design: Retrospective case series., Methods: Patients diagnosed with ocular injuries sustained by bee stings at Miyata Eye Hospital (Miyazaki, Japan) between August 2000 and July 2016 were enrolled. Retrospective data regarding type of bee, visual acuity, and treatment were collected from medical records. Outcomes of the hornet and wasp groups were compared., Results: Five eyes of 5 patients (3 men, 2 women; mean age 44.6±21.2 years [range 9-62 years]) were enrolled. The mean follow-up period was 50.6 ± 57.6 months (range 4 days to 121 months). The causative bee was hornet in 3 cases and wasp in 2. The anterior chamber was irrigated in 2 patients, both from the hornet group. The best-corrected visual acuity at the final visit was no light perception, light perception, and (0.02) in the hornet group, (1.5) and (1.2) in the wasp group., Conclusions: The hornet group exhibited significantly worse prognosis than the wasp group. Identifying the type of bee is important in establishing prognosis.

Purpose: The purpose of this study is to describe the presenting features, management strategies, and clinical outcome following bee sting injury to the cornea., Methods: Retrospective case series involving 11 eyes of 11 patients with corneal bee sting injuries who presented over a period of 2 years. Nine of these 11 eyes had the presence of intact bee stinger in the cornea, which was removed immediately under an operating microscope and sent for microbiological and histopathological evaluation. The patients were managed as per the individual treatment protocol of the respective treating physicians., Results: Six eyes (54.5%) had a good clinical outcome (best-corrected visual acuity [BCVA] >20/40) with medical therapy alone with no need for surgical intervention. Five eyes (45.5%) had a poor clinical outcome (BCVA <20/40) with medical therapy and required surgery; of which three required a combined penetrating keratoplasty with cataract surgery, while one required isolated cataract surgery and one underwent penetrating keratoplasty. Glaucoma was present in 3/5 eyes undergoing surgery, one of which required a trabeculectomy. Five of the six eyes who had a good clinical outcome with medical therapy alone had been treated with concomitant oral steroids, along with topical antibiotic-steroid combination therapy., Conclusion: Oral corticosteroid supplementation to the topical steroid antibiotic treatment in patients with corneal bee sting injury where corneal involvement and anterior reaction is severe at presentation or inflammation not ameliorating with topical steroids alone prevents serious vision-threatening complications such as corneal decompensation, cataract, and glaucoma.

Background: Patients with a corneal foreign body may first present to their general practitioner (GP). Safe and efficacious management of these presentations avoids sight-threatening and eye-threatening complications. Removal of a simple, superficial foreign body without a slit lamp is within The Royal Australian College of General Practitioners' (RACGP's) curriculum and scope of practice. Knowing the rele-vant procedural skills and indications for referral is equally important., Objective: The objective of this article is to provide an evidence-based and expert-based guide to the management of corneal foreign bodies in the GP's office., Discussion: History is key to identifying patient characteristics and mechanisms of ocular injury that are red flags for referral. Examination tech-niques and methods of superficial foreign body removal without a slit lamp are outlined, as well as the procedural threshold for referral to an ophthalmologist.

Open globe injuries complicated with the presence of an intraocular foreign body mostly affect young males and represent a vision threatening condition. We presented the case of a 48-year-old male who presented to our emergency service due to ocular pain and blurred vision in his right eye. A metallic foreign body situated between 1 and 12 o'clock, near the corneoscleral limbus, that perforated the cornea, the iris, the anterior capsule of the lens and the lens, was detected at the slit-lamp examination. We decided to immediately remove the foreign body that was approximately 20 mm long. The following day, traumatic cataract had already developed, so we performed cataract extraction. Despite the dimensions of the intraocular foreign body, the retina was attached and there were no sign of retinal tears or vitreous haemorrhage. The proper management in this case led to good results in spite of the dimensions of the intraocular foreign body.

Purpose: To review the management of keratitis after corneal bee stings and to report a case of deep stromal corneal infiltrate secondary to a retained bee stinger managed conservatively in a patient who presented three days after unsanitary manipulation of the stinger apparatus., Methods: Case report and review of literature., Results: A 57-year-old male beekeeper was evaluated for pain, blurry vision, and photosensitivity after a corneal bee sting. Of note, the venom sac had been removed with dirty tweezers three days prior to his visit. On exam, a focal infiltrate with diffuse edema was seen surrounding a retained bee stinger in the peripheral cornea. Trace cells in the anterior chamber were also noted. Based on a high suspicion for infectious keratitis, a conservative treatment strategy was elected. Administration of broad-spectrum topical antibiotics with concomitant abstention of corticosteroids led to rapid resolution of the symptoms. Over 16 months of follow-up, the stinger has remained in situ without migration and the patient has maintained 20/20 visual acuity without complications. There is debate on the preferred method for the management of corneal injury secondary to bee stings, especially when it is associated with a retained stinger. We herein present our findings in our appraisal of reported cases., Conclusion: In the aftermath of an ocular bee sting, close surveillance for inflammation and infection is essential. Individual manifestations of these injuries vary in timing, type, and severity; therefore, the accessibility of the stinger and the evolving clinical picture should guide therapeutic decisions.

Purpose: To evaluate the medical and surgical management and treatment of ocular injuries with chestnut burr recorded at the Hospital El Bierzo between 2009 and 2015., Methods: A prospective study of ocular injuries with chestnut burr was conducted for the period from 2009 to 2015. Patients were detected in the Emergency Department and referred to the Ophthalmology Department for study and medical and surgical treatment. Ten eyes were evaluated in 10 patients. The injuries ranged from ocular contusion without corneal involvement to trauma with corneal perforation caused by spines. One patient with chronic retention of spines in the intrastromal corneal ring was included., Results: Six of the eyes studied had chestnut burr spines in the cornea, one of which was chronically retained in the intrastromal cornea. One case of spine-induced corneal perforation was also studied. Six of the patients required surgery, 2 required removal of the spine using a slit lamp, 2 required outpatient medical treatments, and a wait-and-see approach was taken in 1 patient. All patients progressed favorably, and no surgical complications were recorded., Conclusions: Proper occupational risk prevention and the use of eye protection glasses are fundamental in avoiding these accidents. Once they have occurred, medical and surgical management must be done early and on an individual basis depending on the severity and location of the injuries, to avoid potentially serious complications.

Corneal emergencies can be due to a number of different causes and may be vision threatening if left untreated. In an attempt to stabilize the cornea, it is of benefit to place an Elizabethan collar on the patient to prevent further corneal damage. This article discusses the diagnosis, prognosis, and management of corneal emergencies in dogs and cats., (Copyright © 2015 Elsevier Inc. All rights reserved.)

Corneal abrasions and corneal foreign bodies are frequently encountered ophthalmological injuries that are commonly diagnosed and managed by primary care physicians. The clinical course of a corneal epithelial defect can range from a relatively benign self-healing abrasion to a potentially sight-threatening complication such as a corneal ulcer, recurrent erosion, or traumatic iritis. A detailed clinical history regarding risk factors and exposure, along with a thorough slit lamp examination with fluorescein dye are essential for proper diagnosis and treatment, as well as to rule out penetrating globe injuries. Referral to an ophthalmologist is recommended in difficult cases or if other injuries are suspected., (Copyright © 2015 Elsevier Inc. All rights reserved.)

A short cut review was carried out to establish whether local anaesthetic should be instilled before or after eye examination in suspected corneal foreign body. 83 papers were found in Medline, Embase and the Cochrane Library using the reported searches, but none presented any evidence to answer the clinical question. It is concluded that there is no evidence to guide the time of installation and that local advice should be followed., (Published by the BMJ Publishing Group Limited.

We present a 39-year-old patient with a penetrating injury of the cornea and anterior lens capsule containing an intralenticular foreign body. One week after the accident, the patient consulted our emergency unit. Clinical examination showed no Seidel II phenomenon. A femtosecond laser-assisted capsulotomy was performed followed by lens removal and intraocular lens implantation. The capsulotomy diameter was increased to 6.7 mm to include the foreign-body area and the break in the anterior capsule. The procedure was uneventful, and the capsule leaf, including the foreign body, was extracted safely., (Copyright © 2013 ASCRS and ESCRS. Published by Elsevier Inc. All rights reserved.)

Corneal abrasions are commonly encountered in primary care. Patients typically present with a history of trauma and symptoms of foreign body sensation, tearing, and sensitivity to light. History and physical examination should exclude serious causes of eye pain, including penetrating injury, infective keratitis, and corneal ulcers. After fluorescein staining of the cornea, an abrasion will appear yellow under normal light and green in cobalt blue light. Physicians should carefully examine for foreign bodies and remove them, if present. The goals of treatment include pain control, prevention of infection, and healing. Pain relief may be achieved with topical nonsteroidal anti-inflammatory drugs or oral analgesics. Evidence does not support the use of topical cycloplegics for uncomplicated corneal abrasions. Patching is not recommended because it does not improve pain and has the potential to delay healing. Although evidence is lacking, topical antibiotics are commonly prescribed to prevent bacterial superinfection. Contact lens-related abrasions should be treated with antipseudomonal topical antibiotics. Follow-up may not be necessary for patients with small (4 mm or less), uncomplicated abrasions; normal vision; and resolving symptoms. All other patients should be reevaluated in 24 hours. Referral is indicated for any patient with symptoms that do not improve or that worsen, a corneal infiltrate or ulcer, significant vision loss, or a penetrating eye injury.

To report the clinical findings and a novel method of removal of bee sting using an endoillumination light source the following methods were used: clinical presentation, slit-lamp photographs, serial endothelial images and surgical management of a case of retained bee sting in the cornea. The bee sting was surgically removed by forceps under focal illumination with an endoillumination light source. Topical steroids and cycloplegics were given postoperatively to control the inflammation. The patient had complete visual recovery and partial resolution of endothelial changes after 1 year of treatment. The clinical picture of a corneal honey bee sting resembles keratouveitis. Focal corneal infiltrate and associated low-grade uveitis tend to persist if treated with topical steroids only. Early recognition and prompt removal of the stinger may help in the early resolution of anterior segment inflammation and prevent irreversible damage to endothelial cells.
