Retinal injury from a laser skin resurfacing device during medical tourism: a public health concern.

BACKGROUND: Laser skin resurfacing is a popular cosmetic procedure for noninvasive skin rejuvenation. Since health insurance plans often do not cover these types of procedures, patients often pay out of pocket. Consequently, there is an incentive to go abroad, where prices are more affordable. However, practitioners in destination countries may lack rigorous training on laser safety, regulatory oversight, or licensing, especially on devices used for "cosmetic" procedures. In certain cases, this can lead to tragic outcomes, especially when underqualified practitioners operate medical-grade laser devices. CASE PRESENTATION: A 29-year-old woman suffered a retinal burn from a handheld Q-switched neodymium-doped yttrium aluminum garnet (Nd:YAG) laser pulse device used to perform skin resurfacing treatment at a medical spa in Vietnam. The patient was not adequately informed about the potential risk to her vision and was not provided with any eye protection. A momentary, unintended laser exposure to the patient's right eye led to irreversible vision loss due to a macular burn. This incident caused immediate pain, followed by the sudden appearance of floaters, along with a retinal and vitreous hemorrhage. Despite treatment with off-label bevacizumab for the development of a choroidal neovascular membrane, vision remained at the level of counting fingers because of the presence of the macular scar. CONCLUSION: When utilizing laser-based devices, it is crucial to employ safety measures, such as the wearing of safety goggles or the use of eye shields to protect ocular tissues from potential damage. The growing availability of cosmetic laser devices presents a substantial public health risk, because numerous operators lack adequate training in essential safety standards, or they neglect to follow them. Furthermore, patients seeking services abroad are subject to the regulatory practices of the destination country, which may not always enforce the requisite safety standards. Further research is needed to determine regional and global incidence of laser-related injuries to help direct educational and regulatory efforts.

Preventing Eye Injuries From Light and Laser-Based Dermatologic Procedures: A Practical Review.

The light and laser-based devices used in cosmetic dermatology practice carry a risk of serious ocular injury if appropriate safety measures are not put in place. Currently there is a lack of enforced regulation around the use of these devices. This raises concerns for the handling of these devices by operators who may not have adequate training and qualifications. There is also no mandated reporting of adverse events, thus precluding determination of the true incidence of laser-induced ocular injuries. To decrease the risk of ocular and periocular laser-induced injuries, several practical measures can be implemented within the clinical setting. Scientific articles were identified by performing a literature review using terms relevant to laser eye safety and a narrative review was performed. This article explores several components of laser eye safety: patient screening and informed consent, clinical environment considerations, operator considerations, protective eyewear selection for operators and patients, when to use a corneal shield, how to place a corneal shield and what to do in the event of a suspected eye injury. It is our prerogative that a functional understanding of the scientific underpinnings of laser eye safety coupled with observance of published standards has the potential to reduce incidents.

The Orbital Bones Protect the Globe From Sharp Periorbital Trauma Injuries.

BACKGROUND: The bones of the orbit hold the globe and periocular structures and protect it and other periocular contents. This has been shown in blowout orbital fractures, as well as in high-energy injuries to the periorbital region. However, there is little information regarding how the orbital bones protect the globe after periorbital trauma from sharp objects. OBJECTIVES: This study reports 4 cases of traumatic injury from sharp objects to the periorbital area and eyelids to demonstrate the protective features of the orbital bones. RESULTS: The anatomy of the periorbital bones clearly protected the globe from direct trauma in all the 4 cases. CONCLUSIONS: There was no harm to the orbit or visual impairment after the successful treatment with definitive surgery.

The Importance of Health Literacy in Addressing Eye Health and Eye Care Disparities.

Disparities in eye health and eye care frequently result from a lack of understanding of ocular diseases and limited use of ophthalmic health services by various populations. The purpose of this article is to describe the principle of health literacy and its central role in enhancing health, and how its absence can result in poorer health outcomes. The article evaluates the current status of health literacy in visual health and disparities that exist among populations. It also explores ways to improve health literacy as a means of reducing disparities in visual health and eye care. Advancing dissemination of health information and enhancing health literacy may help not only to reduce healthcare barriers in the underserved populations but also to lessen visual health disparities.

Safety Guidelines Concerning the Use of Protective Eyewear and Gauze During Laser Procedures.

The advancement of laser technology has seen its use gain popularity across a wide range of specialties to treat diseases, as well as address aesthetic concerns. In order to protect both the patient and the healthcare personnel providing treatment, instruction and knowledge of laser safety remain of utmost importance. In this paper, we discuss the classification of laser systems, review ocular injuries that may be caused by inappropriate laser exposure, and provide background on laser protective eyewear. In addition, we highlight the current recommendations for proper eyewear during laser use outlined in the American National Standards Institute standard Z136.3, Safe Use of Lasers in Health Care. Finally, although it is common in some healthcare facilities to place gauze under external eye shields or use gauze alone over eyes during laser procedures, this practice poses an extreme risk to both patients and healthcare personnel. Therefore, we discuss why the use of gauze under eyewear for any laser procedures is not recommended, and instead, offer suggestions to consider when acquiring safe and comfortable patient eyewear.

Urgent Subconjunctival Needle Decompression for Orbital Compartment Emphysema Caused by Compressed Air Injury.

Orbital compartment syndrome is a critical ophthalmic emergency that needs urgent diagnosis and treatment to prevent permanent vision loss caused by optic nerve compression or retinal ischemia. In this article, we present a child with orbital compartment syndrome caused by orbital emphysema as a result of a rare type of ocular trauma and introduce a simple technique to decompress the pressure. The patient was a 4-year-old boy who experienced a compressed air blast to his left eye. He presented to the emergency department with a frozen globe, tight orbit, and chemosis, without any evidence of globe rupture, conjunctival laceration, and orbital bone fracture. Computed tomographic scan demonstrated extensive subcutaneous, intraorbital, and intracranial emphysema. The pressure was immediately relieved under intravenous sedation by inserting a 27-gauge needle into the chemotic subconjunctival space at the lower lid fornix, followed by gentle manipulation of the globe to help the air escape through the needle. Compressed air injury is a rare type of orbital trauma, and this patient constituted the youngest case ever reported in the English literature, to our knowledge. Air decompression through the conjunctiva as described in this article is a useful technique that can be applied by emergency medicine specialists with special caution for patients with orbital compartment syndrome and orbital emphysema caused by compressed air injury.

Fireworks: boon or bane to our eyes?

Fireworks are an integral aspect of national, cultural and religious festivals globally, featuring in a vast range of celebrations including Diwali in India and New Year's Eve in the USA. We have seen a trend in eye injuries related to the use of fireworks, with millions of people, of which a large proportion comprising children, are injured annually-and rather than falling, as one would hope, this number is remaining stable. A comprehensive study of the impact of firework-related injuries to the eye is not available, and the efforts to mitigate this are not widely discussed in the literature. This literature review therefore focusses on studying the impact of firework-related eye injuries, the effect of legislation on mitigating these injuries and their associated morbidity.

Surgical Management of the Recent Orbital War Injury.

Maxillofacial trauma affects sensitive and essential functions for the human being such as smell, breathing, talking, and the most importantly the sight. Trauma to the orbit may cause a vision loss especially if this trauma yields a high kinetic energy like that encountered during wars. The purpose of the study was to evaluate the surgical outcomes of the orbital war trauma, enriching the literature with the experience of the authors in this field. A total of 16 patients were injured, evacuated, and managed, between June 2014 and June 2017, from the fight between the Iraqi army and the Islamic State of Iraq and Syria (ISIS) in different areas of Iraq. Two-stage protocol was adopted, that is debridement and reconstruction. There were 14 military patients and 2 civilians. The cause of trauma was either bullet or shrapnel from an explosion. In the battlefield, delayed evacuation of the casualties led to increase the morbidity and mortality. Wearing a protective shield over the eye during the war along with fast evacuation highly improved the survival rates.

Further handling recommendations and requirements for the laser devices are drawn and the question of transferring tasks to nonmedical personnel is discussed. The reader should get an idea about the benefits and risks of using lasers in treating patients and be able to set the precise indication on the background of possibilities, adverse effects, and legal aspects.

PENETRATING ORBITOCRANIAL INJURY.

- A case of a 37-year-old female patient is presented. The patient was admitted to the Surgical Emergency Unit after accidental fall on a metal rod when she had sustained stab injury of the right orbit with penetration into the right frontal brain lobe. Multi-slice computed tomography (MSCT) showed penetrating injury and fracture of the right orbital roof without eyeball damage and endocranial impressed bone fragments into the right frontal brain lobe. Urgent surgical intervention was performed by a maxillofacial surgeon and neurosurgeon, including reposition of bone fragments of the orbital roof and cranioplasty. Reconstruction of Tenon's capsule of the right eyeball was performed by an ophthalmologist. From the intraoperative wound swab of the orbit, Bacillus cereus was isolated, therefore the patient was administered ciprofloxacin and rifampicin as recommended by an infectious disease (ID) specialist. Follow up brain MSCT at 15 days and magnetic resonance imaging of the brain at 25 days showed brain edema in the right frontal area and signs of local brain abscess. Intravenous administration of the ciprofloxacin and metronidazole antibiotics with corticosteroids for edema suppression were ordered by the ID physician. Fourteen weeks after this therapy, brain MSCT showed complete abscess regression and no neurologic deficit with only mild psychomotor changes.

Expanding Advocacy for Head Trauma Vision Research Funding.

In this article, we explore the roles of media, research, and advocacy in education and research funding. All three have played critical roles in advancing our understanding of eye, vision, and brain injuries in sports and in the military.

Emergency Decompression of Orbital Emphysema with Elevated Intraorbital Pressure.

BACKGROUND: A case of orbital emphysema associated with elevated intraorbital pressure, presenting as a complication of a paranasal sinus "blow-out" fracture after trauma to the orbit and globe is presented. CASE REPORT: A 45-year-old man developed left globe rupture with orbital emphysema after blunt trauma. A large air pocket in the superior orbit with medial wall fracture and globe tenting was identified on noncontrast computed tomography. Direct needle drainage was performed using a 23-gauge needle attached to a saline-filled syringe with the plunger removed. Rapid release of air bubbles with prompt alleviation of pressure symptoms was observed. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Early diagnosis and management of orbital emphysema can salvage useful function of the globe. The knowledge of this clinical entity and its management can prevent delay and unnecessary referral.

Visual outcome and its prognostic factors in patients presenting with ocular war injuries at an army hospital in Pakistan.

OBJECTIVE: To determine the visual outcome and its prognostic factors in patients presenting with ocular war injuries. METHODS: This descriptive, observational study was conducted at the Combined Military Hospital, Peshawar, Pakistan, from June 2012 to March 2016, and comprised soldiers with ocular war injuries. Informed consent was obtained from all participants. A predesigned proforma was used to record patient's demographic details along with the cause, side, type and severity of injury. Injuries were classified as open globe or closed globe injuries. Ocular trauma score grade was used to describe the severity of injury. RESULTS: There were 210 participants with an overall mean age of 29.34±5.35 years (range: 20-43 years). All of them were male. Left side was more frequently involved, i.e. in 126(60%) cases. The most frequent underlying cause was improvised explosive device blast injury 114(54.3%), followed by blunt trauma 42(20%) and road traffic accidents 24(11.4%). Closed globe injuries were more frequent and were recorded in 120(57.1%) patients. The visual outcome was good in 62(29.5%) patients, followed by fair in 51(24.3%) patients while 51(24.3%) patients had worst visual outcome. When stratified, there was no significant difference of worst visual outcome with patient's age (p=0.279). However, improvised explosive device blast (p=0.002), open globe injury (p=0.000), ocular trauma score grade 1; open globe (p=0.049), closed globe (p=0.003) were associated with significantly higher frequency of worst visual outcome. Zone-III injury was also prognostic of worst visual outcome, but the difference was significant only in case of open globe injury (p=0.003). CONCLUSIONS: Improvised explosive device blast, open globe injury and ocular trauma score grade 1 were poor prognostic features and resulted in significantly higher frequency of poor visual outcome.

[The impact of fireworks: the context of facial trauma]. / De impact van vuurwerk: achtergronden van het aangezichtsletsel.

In the Netherlands the general public can legally use fireworks on New Year's Eve. Despite the fact that the public is well aware of the dangers of fireworks, fireworks accidents occur in which the victims suffer a variety of injuries. In addition to burns, injuries to fingers and/or hands are most common. However, injuries to the eye, which can also involve facial trauma, frequently occur as well. Trauma mainly occurs as a result of the destructive effects of the wave of pressure released by the explosion. The best preventive measure would be to prohibit the use of fireworks by amateurs. Until such time, people should be advised to wear protective fireworks glasses when outside so that damage to the eyes from legal fireworks at least can be prevented.

Inclined head position improves dose distribution during hippocampal-sparing whole brain radiotherapy using VMAT.

PURPOSE: Hippocampal-sparing whole brain radiotherapy (HS-WBRT) aims to preserve neurocognitive functions in patients undergoing brain radiotherapy (RT). Volumetric modulated arc therapy (VMAT) involves intensity-modulated RT using a coplanar arc. An inclined head position might improve dose distribution during HS-WBRT using VMAT. MATERIALS AND METHODS: This study analyzed 8 patients receiving brain RT with inclined head positioning. A comparable set of CT images simulating a non-inclined head position was obtained by rotating the original CT set. HS-WBRT plans of coplanar VMAT for each CT set were generated with a prescribed dose of 30 Gy in 10 fractions. Maximum dose to the hippocampi was limited to 16 Gy; to the optic nerve, optic chiasm, and eyeballs this was confined to less than 37.5 Gy; for the lenses to 8 Gy. Dosimetric parameters of the two different plans of 8 patients were compared with paired t-test. RESULTS: Mean inclined head angle was 11.09 ± 0.73°. The homogeneity (HI) and conformity (CI) indexes demonstrated improved results, with an average 8.4 ± 10.0 % (p = 0.041) and 5.3 ± 3.9 % (p = 0.005) reduction, respectively, in the inclined vs. non-inclined position. The inclined head position had lower hippocampi Dmin (10.45 ± 0.36 Gy), Dmax (13.70 ± 0.25 Gy), and Dmean (12.01 ± 0.38 Gy) values vs. the non-inclined head position (Dmin = 12.07 ± 1.07 Gy; Dmax = 15.70 ± 1.25 Gy; Dmean = 13.91 ± 1.01 Gy), with 12.8 ± 8.9 % (p = 0.007), 12.2 ± 6.8 % (p = 0.003), and 13.2 ± 7.2 % (p = 0.002) reductions, respectively. Mean Dmax for the lenses was 6.34 ± 0.72 Gy and 7.60 ± 0.46 Gy, respectively, with a 16.3 ± 10.8 % reduction in the inclined position (p = 0.004). Dmax for the optic nerve and Dmean for the eyeballs also decreased by 7.0 ± 5.9 % (p = 0.015) and 8.4 ± 7.2 % (p = 0.015), respectively. CONCLUSION: Inclining the head position to approximately 11° during HS-WBRT using VMAT improved dose distribution in the planning target volume and allowed lower doses to the hippocampi and optic apparatus.

Real Time Navigation-Assisted Orbital Wall Reconstruction in Blowout Fractures.

BACKGROUND: Limitation in performing restoration of orbital structures is the narrow, deep, and dark surgical field, which makes it difficult to view the operative site directly. To avoid perioperative complications from this limitation, the authors have evaluated the usefulness of computer-assisted navigation techniques in surgical treatment of blowout fracture. METHODS: Total 37 patients (14 medial orbital wall fractures and 23 inferior orbital wall fractures) with facial deformities had surgical treatment under the guide of navigation system between September 2012 and January 2015. RESULTS: All 37 patients were treated successfully and safely with navigation-assisted surgery without any complications, including diplopia, retrobulbar hematoma, globe injury, implant migration, and blindness. CONCLUSIONS: Blowout fracture can be treated safely under guidance of a surgical navigation system. In orbital surgery, navigation-assisted technology could give rise to improvements in the functional and aesthetic outcome and checking the position of the instruments on the surgical site in real time, without injuring important anatomic structures.
