This study addresses the issues of the limited or unavailable unmanned aerial vehicle (UAV) image matching labels, differences in imagery between UAV and ground cameras, and the limited UAV airborne computer memory in UAV visual navigation. To tackle these challenges, a novel unsupervised UAV image matching network called USuperGlue is developed, which leverages local self-attention. The aim is to enhance the precision and recall of the matching process. To achieve this, a local self-attention module is designed to specialize each feature point at the end of the encoding, thereby further improving the matching precision. Subsequently, the encoded features are decoded to extract scores, keypoints, and feature descriptors. During the feature matching stage, an unsupervised matching network is constructed using SuperGlue, a graph neural network that incorporates multi-head attention, to match the feature descriptors of image pairs. The experiment conducted training of the unsupervised network using the Drone dataset and COCO dataset. The simulation results demonstrate that the trained USuperGlue model achieves superior precision and recall, making it a highly effective solution for UAV image matching. [ABSTRACT FROM AUTHOR]

Purpose: To study and compare the demographic and clinical profile of acute ocular burns (AOB) in children and adults. Methods: This retrospective case series included 271 children (338 eyes) and 1300 adults (1809 eyes) who presented to two tertiary eye care centers within one month of sustaining AOB. Data regarding demographics, causative agents, severity of injury, visual acuity (VA), and treatment were collected and analyzed. Results: Males were more commonly affected particularly among adults (81% versus 64%, P < 0.00001). Among children, 79% sustained domestic injuries, whereas 59% of adults had work-place injuries (P < 0.0001). Most cases were due to alkali (38%) and acids (22%). Edible lime (chuna, 32%), superglue (14%), and firecrackers (12%) in children, and chuna (7%), insecticides, lye, superglue (6% each), toilet cleaner (4%) and battery acid (3%) in adults, were the main causative agents. The percentage of cases with Dua grade IV-VI was greater in children (16% versus 9%; P = 0.0001). Amniotic membrane grafting and/or tarsorrhaphy were needed in 36% and 14% of affected eyes in children and adults, respectively (P < 0.00001). The median presenting VA was logMAR 0.5 in children and logMAR 0.3 in adults (P = 0.0001), which improved significantly with treatment in both groups (P < 0.0001), but the final VA in eyes with Dua grade IV-VI burns was poorer in children (logMAR 1.3 versus logMAR 0.8, P = 0.04). Conclusion: The findings clearly delineate the at-risk groups, causative agents, clinical severity, and treatment outcomes of AOB. Increased awareness and data-driven targeted preventive strategies are needed to reduce the avoidable ocular morbidity in AOB.

This paper presents a deep feature-based RGB-D odometry system using SuperPoint and SuperGlue. Geometry- based visual odometry systems face challenges, such as tracking failures in difficult scenes and scale ambiguity. As for the scale ambiguity problem, the map need not be initialized because 3D information can be obtained by using the depth cameras installed in smartphones in recent years. By contrast, learning- based visual odometry systems can estimate even particularly difficult scenes compared with ORB, SIFT, and LIFT features. We integrated this into our RGB-D odometry system. Compared with geometry-based and learning-based visual odometry systems, the proposed deep feature-based RGB-D odometry system achieved higher accuracy. [ABSTRACT FROM AUTHOR]

This study aimed to achieve the accurate and real-time geographic positioning of UAV aerial image targets. We verified a method of registering UAV camera images on a map (with the geographic location) through feature matching. The UAV is usually in rapid motion and involves changes in the camera head, and the map is high-resolution and has sparse features. These reasons make it difficult for the current feature-matching algorithm to accurately register the two (camera image and map) in real time, meaning that there will be a large number of mismatches. To solve this problem, we used the SuperGlue algorithm, which has a better performance, to match the features. The layer and block strategy, combined with the prior data of the UAV, was introduced to improve the accuracy and speed of feature matching, and the matching information obtained between frames was introduced to solve the problem of uneven registration. Here, we propose the concept of updating map features with UAV image features to enhance the robustness and applicability of UAV aerial image and map registration. After numerous experiments, it was proved that the proposed method is feasible and can adapt to the changes in the camera head, environment, etc. The UAV aerial image is stably and accurately registered on the map, and the frame rate reaches 12 frames per second, which provides a basis for the geo-positioning of UAV aerial image targets.

Aiming at the visual odometer of feature point method,the change of illumination and view angle could lead to the instability of feature point extraction,which affects the accuracy of camera pose estimation,a monocular vision odometer modeling method based on deep learning SuperGlue matching algorithm is proposed.Firstly,the feature points are obtained by SuperPoint detector,and the resulting feature points are encoded to obtainvectors containing the coordinates and descriptors of the feature points.Then the more representative descriptors are generated by attentional GNN network.We useSinkhorn algorithm to solve the optimal score distribution matrix.Finally,according to the optimal feature matching,the camera pose is restored,and the ca-mera pose is optimized by using the minimum projection error equation.Experiments show that the proposed algorithm is not only more robust to view angle and light change than the visual odometer based on ORB or SIFT,without back-end optimization,but also the accuracy of absolute trajectory error and relative pose error is greatly improved,thus the feasibility and superiority of the deep learning based SuperGlue matching algorithm in visual slam are further verified.

• A novel approach to intelligently analyze litchi fruit abscission of branches in the orchard. • A fixed-point and fixed-focus data acquisition system was developed. • The improved SuperGlue network was employed to match branches and extract the ROI-B of the target branch. • The fruit abscission on a total of 80 branches , over a continuous 56-day period was analysed by using the proposed method. Automatic tracking of litchi fruit abscission provides important information for the orchard management. Currently, the prevalent method for tracking litchi fruit abscission involves manual selection of branches followed by daily fruit counting, a process deemed both inefficient and subjective. Therefore, this paper proposed a novel approach that integrated an improved image matching and object detection algorithms to intelligently analyze litchi fruit abscission of branches in the orchard. The method consisted of three steps. Firstly, an automatic fixed-point focus system was developed to capture long-term image sequences of selected branch areas. From April 27th to June 21st, 2022, the system autonomously navigated to specified locations and automatically adjusted the focal length to capture daily images of selected branches, thereby forming image time series is crucial for analysis. Secondly, to reduce fruit counting errors due to interferences from other branches, an improved SuperGlue algorithm named SE2-SuperGlue was developed to match branches and extract the region of interest of the target branch (ROI-B) from the image time series. The SE2-SuperGlue algorithm introduced an equivariant steerable CNN that is equivariant to translations and image rotations, rendering it robust to rotations and ensuring accurate matching amid changes in branch angles. Thirdly, the ROI-B sequences were input into the YOLOv8n to detect litchi fruits, yielding tracking results of litchi fruit abscission on the image time series. Experimental results showed the good performance of the proposed method. The SE2-SuperGlue network achieved higher matching score (0.53) and a speed of 177 ms/frame compared to conventional matching algorithms, successfully extracting the ROI-B sequence. Additionally, YOLOv8n achieved an mAP@0.5 of 98.7 %, and the correlation coefficient R2 between prediction and ground truth for automatic tracking of daily fruit count over a 56-day image time series of selected branches was 0.98. Furthermore, the study analyzed a continuous 56-day image sequence depicting relative fruit abscission for 80 branches of three varieties (Guiwei, Nuomici, and Huaizhi), along with the peaks of fruit abscission.

The purpose of this study is to run a review on possible superglue injuries to the eye. In this review, previous papers regarding the harmful impacts of superglue were systematically studied. Superglue eye injuries have been common during the three last decades and most of them were accidental and preventable by introducing safety issues and although it may be toxic for the tissues, it is not associated with long term morbidity. This paper addresses the management of superglue injuries and shows the importance of the prevention of ocular superglue injuries.

A 5-year-old Japanese boy presented to the emergency room of our hospital because his right eye had been glued shut for 2 h following instillation of cyanoacrylate adhesive. The clinical examination showed redness of the right upper and lower lid skin; the right eyelid margins adhered to each other because of matting of the eyelashes, and crystallized glue was found within the matted eyelashes. The “hook” technique, which separates the eyelids using a blunt-tip device, was performed to separate the lids. The technique seems to be simple and safe for physicians such as ophthalmology residents to use to treat cyanoacrylate-induced adhesion of the eyelids of patients who often first present to their local emergency room as in our case.

Background: Foreign body insertion in the urethra and bladder are relatively rare. These patients usually insert foreign body in urethra for eroticism, inquisitiveness, or as a consequence of disinhibited or disturbed behavior. Case presentation: Herein, we report a case of 41-year-old man presented with weak stream and suprapubic pain. Due to incontinence, he instilled superglue into his urethra. On perineal examination, a foreign body was palpable in the penile urethra. A 10 cm dried superglue block got out with incision at glance. Conclusion: Urethral foreign bodies are mostly found on physical examination and clinical history. Although imaging modalities are commonly used for FBs detection, the necessity of imaging modalities are still a controversy.

Thin polymer films (TPFs) are indispensable elements in numerous technologies ranging from liquid encapsulation to biotechnology to electronics. However, their production typically relies on wet chemistry involving organic solvents or chemical vapor deposition, necessitating elaborate equipment and often harsh conditions. Here, an eco-friendly, fast, and facile synthesis of water-templated interfacial polymers based on cyanoacrylates (superglues, CAs) that yield thin films with tailored properties is demonstrated. Specifically, by exposing a cationic surfactant-laden water surface to cyanoacrylate vapors, surfactant-modulated anionic polymerization produces a manipulable thin polymer film with a thickness growth rate of 8 nm min -1 . Furthermore, the shape and color of the film are precisely controlled by the polymerization kinetics, wetting conditions, and/or exposure to patterned light. Using various interfaces as templates for film growth, including the free surface of drops and soap bubbles, the developed method advantageously enables in situ packaging of chemical and biological cargos in liquid phase as well as the encapsulation of gases within solidified bubbles. Simple, versatile, and biocompatible, this technology constitutes a potent platform for programmable coating and soft/smart encapsulation of fluids., (© 2024 The Author(s).

Objectives: To compare the efficacy of aural foreign body (FB) extractions among medical care settings and determine if certain methods of extraction resulted in higher failure rates and procedural complications. Study Design: Case series with chart review. Setting: Emergency departments (EDs), urgent cares (UCs), pediatric primary care providers (PCPs), and otolaryngologists (ENTs). Methods: A total of 366 pediatric patients with EAC foreign bodies at a tertiary children's hospital and associated satellite clinics. Results: The ED/UCs (17.46%), PCPs (75.22%), and ENTs (94.54%) exhibited highly variable success rates for pediatric aural FB extractions. Complications were considerably higher for attempts by ED/UCs (22.22%) as compared with PCPs (2.61%) and those of unclear etiology (2.73% of all attempts). Use of balloon-tipped catheters and adhesive-tipped probes (eg, cyanoacrylate/superglue) for FB extraction exhibited 0% success rates with high severity of complications. Conclusion: Our statistics provide an example in which ED/UCs had higher failure rates at pediatric aural FB removals when compared with PCPs and ENTs. If a single provider (PCP or ED/UC) fails to retrieve an aural FB or if the provider is not comfortable conducting the procedure, then referral to an ENT is preferable to another PCP or ED/UC. Our evidence reveals that balloon-tipped catheters and adhesive-tipped probes for FB removal in the pediatric population are prone to failure and higher rates/severity of complications.

Sotonibi AH Cookey, Ireju O Chukwuka, Ogochukwu A Sibeudu Department of Ophthalmology, University of Port Harcourt Teaching Hospital, Rivers State, Nigeria Background: Ocular superglue injury is uncommon all over the world.Aim: To report a case of self-inflicted accidental ocular superglue injury. Methods: A case of ocular injury is described in a 29-year-old adult, following inadvertent instillation of superglue instead of a prescribed steroid ointment into the right eye, in the dark. Results: There was matting of the upper and lower lid margin and eyelashes precluding view of the ocular structures. The eyelids were separated by gently peeling off the superglue from the lids and lid margins. The glue-matted eye lashes were trimmed and the glue on the cornea and conjunctival surface was gently removed. Subsequently, a corneal ulcer was seen which was managed with topical antibiotics, systemic analgesics, and vitamins. Conclusion: Similarity between the tubes of eye ointments and household superglue accounts for the accidental eye injury. Keywords: superglue, ocular injury, sticking of eyelids, corneal abrasion

Burns are a common cause of pediatric injury and represent significant morbidity and mortality in this age group. In children, most burns are thermal, resulting from exposure to a hot surface, liquid, or fire. Cyanoacrylate is a liquid compound commonly found in households, mainly in "superglue" and nail glue. This compound solidifies through an exothermic reaction that is magnified when in contact with certain fibers that act as catalysts, such as cotton. In these circumstances, intense heat is produced in the contact area, potentially causing severe thermal burns. Despite its widespread availability, there is a paucity of safety information about cyanoacrylate and its role as a cause for burns. In the literature, only 18 cases of cyanoacrylate burns are reported in children. We present two cases of pediatric burns with cyanoacrylate and a review of the literature. [ABSTRACT FROM AUTHOR]

Ear canal foreign bodies are commonly encountered in the field of otolaryngology. This is especially common in the pediatric otolaryngology discipline. As a foreign body, cyanoacrylate glue (also called "super glue") can be difficult to remove and cause significant patient distress. Multiple solvents can be described as aiding in removing such foreign bodies. Here, a case is described in which hydrogen peroxide and acetic acid were used sequentially to remove cyanoacrylate glue from the external auditory canal. We describe a technique allowing en bloc removal of the cyanoacrylate glue. Thankfully, the patient's hearing returned to baseline post-operatively with minimal complications. Overall, cyanoacrylate glue can be a very difficult foreign body to remove from the ear canal. In this case, the sequential use of hydrogen peroxide and acetic acid to soak the glue was a safe and successful method to facilitate glue removal from the ear canal., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Ahluwalia et al.)

This study presents a number of pseudo‐operational trials on plastic bags investigating the double‐ and co‐fuming process of a one‐step fluorescent cyanoacrylate (LumicyanoTM) in comparisons with the two‐step process with basic yellow 40 (BY40) staining for the detection of latent fingermarks. The results demonstrate that both Lumicyano solution and dye contribute to the increased detection of latent fingermarks during the double‐fuming process (trial 1). Co‐fuming the Lumicyano solution and dye separately (at a concentration of 8%) but simultaneously was less effective than 8% Lumicyano (trial 2). Co‐fuming Lumicyano 8% and an additional 8% Lumicyano dye by weight was more effective than Lumicyano 8% (trial 3), possibly due to increased fluorescent material deposition during co‐fuming allowing for better visualization. The use of BY40 after Lumicyano resulted in a considerable increase in detected fingermarks. [ABSTRACT FROM AUTHOR]

AIM: To report the frequency, associated risk factors and characteristics of cases referred to Farabi Eye Hospital with ocular superglue injuries. METHODS: In a descriptive cross-sectional study conducted between December 2012 and February 2013, patients with ocular superglue injuries were evaluated. Age, sex, educational level, location, time, mechanism, type, site and time of eye injury were gathered through interview using a customized questionnaire. All participants had given consent to undergo thorough eye examination. RESULTS: Over the course of three months, 105 patients with ocular superglue injuries enrolled in the study, including 56(53.3%) men and 49(46.7%) women with the mean age of 24.7±11.6 (range, 2 to 53)y. The right eye, left eye and both eyes were involved in 52%, 42% and 6% of the patients, respectively. Most of injuries had occurred at home (72.4%) and at night (55%). More than half of patients (52.4%) did not take any primary aids following the ocular injury. Patient carelessness (78.1%), childhood curiosity and lack of parental supervision (11.4%), storing superglue in inappropriate places and inadvertently using superglue as eye drops due to poor vision (2.9%), inadequate awareness of superglue applications [used to stick on artificial nails (3.8%), artificial eyelashes (1.9%) and broken tooth (1%)] and being assaulted with glue (1%) were common risk factors. CONCLUSION: The frequency of ocular superglue injuries in patients referred to Farabi Eye Hospital is relatively high. This finding underlines the importance of public education and awareness about superglue injuries to the eye and taking protective measures and safety strategies in order to prevent these injures.

Abstract Foreign bodies in ear are a common occurrence and are commonly seen in the practice. But some foreign bodies require special attention. We here describe a unique situation of cynoacrylate glue or superglue in the external auditory canal which was removed using acetone solution. Acetone solution instilled in the ear canal enabled complete removal of the glue while preserving the anatomy of the ear canal and tympanic membrane.

During the UK riots in August 2011, large volumes of bricks and stones were used as weapons or projectiles in acts of violence or to gain illegal entry to properties. As a result, it has been emphasised that it is necessary to determine suitable chemical treatment(s) that will enable the development of fingermarks on such items in order to identify those involved. This study has undertaken the task of attempting to develop latent fingermarks on common house bricks, limestone and sandstone using current techniques including ninhydrin and fluorescence. Results produced have shown that, with fluorescent fingerprint powder, silver nitrate and superglue providing the best results, it is now possible to enhance fingermarks that were previously left undeveloped. In addition, Isomark T-1 Rapid Grey High Resolution Forensic Impression Material has proved extremely effective as an alternative method of recovering fingermarks developed with fluorescent fingerprint powder.

Abstract: The potential for enhancement and recovery of latent fingerprints on a variety of foodstuffs has been investigated. In general, black magnetic powder and black powder suspensions appear to be the most successful enhancement techniques with a high number of ridge detail-developed prints over a selected time scale. Banana, apple and tomato surfaces showed enhancement of latent prints but potato and egg surfaces proved to be less successful. [Copyright &y& Elsevier]

Vacuum metal deposition (VMD) has been previously demonstrated as an effective development technique for latent fingermarks and in some cases has been shown to enhance prints developed with cyanoacrylate (CA) (superglue) fuming. This work utilizes scanning electron microscopy (SEM) to investigate the interactions of the two development techniques when applied to latent fingermarks on low-density polyethylene. CA is shown to act principally on the eccrine deposits around sweat pores, where polymerization results in long polymer fibrils a few 100 nm in width. Subsequent VMD processing results in additional areas of development, for example, between pores. However, the primary mode of deposition of zinc is by interaction with the polymerized CA, the fibrils of which become decorated with zinc nanoparticles. Areas with limited CA deposition and no significant polymerization are also enhanced with the VMD process, resulting in increased print development. [ABSTRACT FROM AUTHOR]

Background: Ocular chemical injuries due to accidental exposure or application of cyanoacrylate, commonly known as "superglue," have increased over the past 30 years. However, current treatment options to relieve eyelid adhesions due to cyanoacrylate applications are difficult to successfully execute and can require sedation or general anesthesia. Here we describe a simple technique to release eyelid adhesions due to cyanoacrylate, or other adhesive agents, that can be successfully performed at bedside without sedation.Discussion: Topical anesthetic is instilled in the involved eye through an opening identified in the lid fissure. A Jameson muscle hook is inserted through the opening with the distal element of the hook normal to the surface of the eye. The hook is then pulled parallel to the lid margins and through the site of adhesion while counter pressure is applied with the fellow hand in the opposite motion of the hook. Residual glue from the eyelashes can be trimmed with blunt-tip scissors. Examination of the eyelids and ocular surface after application of the technique to open the eyelids showed successful release of adhesion sites with no additional injuries to the eye itself.Conclusions: A Jameson muscle hook can be used in emergency departments to safely and successfully relieve eyelid adhesions due to the inadvertent application of cyanoacrylate glue without the use of general anesthesia.

We evaluated 4 suggested treatments for cyanoacrylate (CA) eyelash adhesion. Nylon paintbrushes were used to simulate human eyelashes. Brushes were treated with one drop of CA and allowed to dry. The brushes were randomly assigned to one of 6 treatment groups: Bacitracin, water, K-Y Jelly, baby shampoo, acetone (+control), and no treatment (-control). Two blinded investigators independently rated each brush to determine if the treatment decreased the adhesion of the bristles. Six brushes were assessed for each therapy. No treatment option was superior to control, and all treatments except acetone had no effect on bristle adherence. Our results suggest these treatments are unlikely to be clinically useful for removing CA from eyelashes. [ABSTRACT FROM AUTHOR]

Multimerization of single-domain antibodies (sdAbs) is instrumental for construction of antibody molecules with high avidity, extended in vivo half-life, and tailor-made biological activity. Two-component superglues, based on bacterium-derived peptides (Tags) and small protein domains (Catchers) that form isopeptide bonds when in close proximity, enable the creation of multimers by simply mixing of the individual components. Here, we provide detailed methods for the construction of sdAbs and scaffolds bearing genetically fused superglue components and their assembly into multimeric complexes., (© 2022.

Primary lung cancer is an extremely rare neoplasm in young adults. We report a case of a primary lung adenocarcinoma in an 18-year-old man who presented for examination of a solitary nodule located in the right lower lobe of the lung. A right lower lobectomy was performed with an incomplete resection because of pleural dissemination (pT4N2M0 stage IIIB adenocarcinoma). Intrathoracic chemotherapy (cisplatin, 50 mg/body) was administered initially, followed by systemic chemotherapy (carboplatin + paclitaxel). A bronchopleural fistula occurred 2 months postoperatively and was successfully treated with conservative therapy, including thoracic drainage, intrathoracic fibrin glue administration, and transbronchial superglue administration. Thereafter, a total of five courses of systemic chemotherapy with minor changes in the administration regimen were performed. The patient was alive and with no evidence of recurrence at his 5-year follow-up. [ABSTRACT FROM AUTHOR]

The effectiveness and suitability of a portable cyanoacrylate fuming system (LumiFume™) with Lumicyano™ at detecting latent fingermarks was assessed. The first phase of the study compared the LumiFume™ system with traditional cabinet fuming and black/white powder suspension for the development of latent fingermarks on a variety of surfaces (glass, plastic bin bag, laminated wood and tile) by means of depletion series' from 10 donors and four ageing periods (1, 7, 14 and 28 days). The portable fuming system provided superior quality of developed marks on glass and laminated wood whereas powder suspension was better on bin bags and all three techniques were comparable on tile. A decrease in mark quality was recorded from 1 to 14 days for the fuming techniques before an increase at 28 days. Lumicyano™ fluorescence stability studies over a 28 day period by means of depletion series' on glass slides and plastic bin bags revealed better quality marks for the portable system LumiFume™; however, storing marks under light conditions expedited deterioration for both systems. All marks developed with Lumicyano™ were subsequently treated with BY40 resulting in further improvement in mark quality for all substrates and ageing periods, with the exception of laminated wood which absorbed the fluorescent stain reducing the contrast in the process. The second phase of the study consisted of a pseudo-operational trial on 300 various substrates (e.g. glass bottles, aluminium cans, plastic bags) recovered from recycling bins. LumiFume™ and Lumicyano™ yielded 1469 marks whereas Lumicyano™ cabinet fuming and powder suspension yielded 1026 and 641 marks respectively. Similar to the first phase of the study, further treatment of the Lumicyano™ treated marks with BY40 resulted in further quality improvement as well as additional new marks. The LumiFume™ system produced results at least equivalent to the traditional cabinet fuming with Lumicyano™ highlighting its potential for implementation into casework to process crime scenes.

Superglue monomers belong to a family of cyanoacrylates that are known for their very rapid polymerization upon contact with moist surfaces. Their biodegradation and low toxicity make them attractive as medical and veterinary adhesives. Although the fast-acting polymerization characteristics have been successfully utilized to design nanoscale polymeric particles that can carry drugs or other inorganic nanoparticles, it constitutes a significant drawback if one desires to produce other forms of functional biodegradable acrylics, such as coatings, sheets, or nanocomposites. This is because rapid polymerization in air creates highly porous and brittle structures. Here, we address this drawback by reporting a simple and inexpensive method of fabricating highly transparent (>92%) polyethylcyanoacrylate (PECA) coatings by dispersing the monomer in a fragrance-classified green liquid, cyclopentanone. The resulting transparent coatings were hydrophilic but with slippery wetting characteristics, suitable as efficient fog-harvesting templates. Furthermore, another fragrance liquid, benzyl alcohol, is introduced as a plasticizer and co-solvent to overcome its brittleness while retaining its transparency. The same plasticized monomer solutions, dispersing low concentrations of graphene (<0.5 wt %), were allowed to self-assemble on stainless steel surfaces, forming low-friction and anti-wear dry lubricants by decreasing the steel friction coefficient and wear rate by 6- and 10-fold, respectively.

This research successfully demonstrated the first use of simultaneous superglue & iodine fuming on leather surfaces compared to superglue, iodine, superglue-iodine and iodine-superglue fuming methods which typically give low fingermark yields. A novel fuming chamber was developed and used for simultaneous superglue & iodine fuming. Results show that the simultaneous fuming method produced significantly better enhancement for light-coloured leather substrates relative to other processing procedures, but was found to be ineffective on dark-coloured leather. However, superglue, as one of the most common methods in practice, was found to be effective for freshly deposited latent fingermarks on dark-coloured leather. The newly designed chamber for the simultaneous fuming method has proved to be fast, effective and delightfully easy to use., (Copyright © 2017 Elsevier B.V. All rights reserved.)

This is a case regarding a 35-year-old gentleman who presented to the Accident and Emergency department at Walsall Manor Hospital. He had mistakenly placed cyanoacrylate ('superglue') into his right ear canal in the early morning. In terms of its removal, an initial attempt was made in the Ear, Nose and throat (ENT) outpatient clinic which proved to be unsuccessful due to the amount of discomfort it caused the patient. Therefore, it had to be removed under general anaesthesia.

Aim: To report various ocular lesions caused by accidental instillation of superglue., Methods: Three cases of ocular injuries are described in children aged 6 years, 3 years and 8 months, following accidental instillation of superglue in the eye., Results: In the first case there was sticking of eyelashes in the medial 1/3 of eyelids in both eyes. In the second case sticking of eye lashes was present in the lateral 1/3 of eyelids in the left eye. In the third case, superglue was present on the right cheek, above the right ear and sticking of eyelids in medial 1/3 in right eye. The eyelids were separated by pulling the lid margins with fingers in the first case and later on superglue was removed by trimming the eyelashes; and by direct trimming the eyelashes in second and third cases. There was no injury to other structures of anterior segment in the first two cases. However, removal of the superglue on the cornea resulted in corneal abrasion in the third case which healed with medical treatment and patching of the right eye., Conclusion: Accidental instillation of superglue is possible because of the appearance of the tube like eye ointment tube. Immediate medical aid will prevent ocular morbidity.
