Management of Corneal Foreign Bodies 10 mins The talk focuses on the appropriate steps towards initial management and potential long-term complications of a patient with a corneal foreign body. Situations, including work environments that may predispose a patient to such injuries are highlighted. Initial Management of Open Globe Injury and/or Suspected Intraocular Foreign Body 15 mins The open globe injury (or ruptured globe) is the most feared surgical emergency of the eye. The initial management aims to reduce further prolapse of ocular contents, prevent superimposed infection and to rule out an intraocular foreign body, which would require removal by vitreoretinal surgeons. The talk discusses the common situations where a missile injury to the eye should be suspected and the steps in initial triage and patient stabilization. Eyelid Lacerations and Orbital Injury How to Avoid Long-term Disfiguration 15 mins Eyelid lacerations and orbital fractures are common in sport-related injuries. They are also seen in cases of assault and dog bite. The aim of this talk is to discuss situations where urgent orbital repair is necessary, such as in the case of trap door fractures with muscle entrapment. This talk also highlights the importance of restoring integrity to the eyelid margin in full thickness lacerations to prevent long-term deformity. Trauma in Paediatric Patients Special Considerations and Non-Accidental Injuries 15 mins Management of trauma in a paediatric patient can be a difficult experience due to an incomplete history, difficulty in cooperation during physical examination and risk of amblyopia. This talk will outline the management plan for cases of trauma in paediatric patients. Of most concern in trauma cases involving children is the possibility of non-accidental injury that may be masked by an unreliable caregiver as the historian. This talk also aims to discuss the risk factors, salient symptoms and signs and medicolegal concerns for non-accidental injuries.
SESSION 3: MANAGEMENT OF ANTERIOR SEGMENT EMERGENCIES Management of Chemical and Thermal Injuries to the Eye 10 mins Chemical and thermal burns to the ocular surface are considered true ophthalmological emergencies as immediate treatment can prevent long-term visual impairment, severe disfigurement and major discomfort. This talk highlights the common sources of chemical and thermal injury, including types that are especially damaging to the ocular surface like lye and industrial cleaning agents. This talk also discusses the crucial steps towards immediate on-site management and follow-up treatment for such patients. Management of Infective Keratitis 15 mins Infective keratitis is common in Hong Kong and usually related to improper use of soft contact lenses. This talk details the common situations and pathogens involved in infective keratitis and the appropriate steps towards initial management and referral. As delayed identification and inappropriate treatment can result in blindness, the talk will focus on salient symptoms and physical signs that point towards a likely case of infective keratitis. Management of Acute Angle Closure Glaucoma 15 mins An acute angle closure attack is an important sight-threatening cause of acute red eye in Southeast Asia. Eyes with short axial lengths are especially predisposed to this condition. This talk aims to discuss the risk factors, precipitating factors (including systemic medications), and salient symptoms and signs of an acute angle closure attack. The talk will also summarize the immediate treatment measures that can potentially save sight. Emergencies after Anterior Segment Surgery 15 mins Anterior segment surgery is common, including cataract surgery, cornea transplantation, glaucoma filtration surgery and laser refractive surgery. Such procedures have early complications that require timely and appropriate attention. This talk outlines the common acute complications after anterior segment surgery as well as the initial steps towards triage and management of such patients.
SESSION 4: MANAGEMENT OF POSTERIOR SEGMENT EMERGENCIES Flashes and floaters Prevention and Management of Retinal Detachments 15 mins The sudden appearance of flashes and floaters in the eye is an extremely alarming symptom for patients, with a significant number of them seeking help at emergency departments. The underlying cause is an acute posterior vitreous detachment. This talk aims to discuss the symptoms and signs of acute posterior vitreous detachment and its associated risks, including retinal holes, retinal tears and retinal detachment. Sight-threatening Complications in Diabetics 15 mins Diabetes is a major chronic condition affecting working-age populations. A significant number of patients suffer sight-threatening complications as a result of diabetes. These include proliferative diabetic retinopathy and diabetic macula edema. This talk aims to discuss the importance of timely referral and management of such complications to prevent long-term visual morbidity. Acute Visual Loss in Patients with Macula Degeneration 10 mins Age-related macula degeneration is the most common cause of irreversible blindness in the elderly. The most devastating subtype is exudative or wet age-related macula degeneration, where patients present with acute visual loss and distortion. This talk aims to discuss simple screening methods to detect possible exudative changes, as well as outline the principles of management for these patients to prevent long-term visual morbidity. Acute Visual Loss due to Retinal Vascular Occlusive Diseases Retinal venous and arterial occlusion are important causes of acute visual loss. In particular, retinal arterial occlusion is a true ophthalmological emergency, as delayed treatment will result in irreversible visual loss. This talk will outline the risk factors and initial management for patients with retinal vascular occlusive disease. Additionally, this talk will outline the importance of systemic vascular risk factor control in such patients due to the significantly increased risk of mortality. Vision Loss in the Immunocompromised Patient 15 mins Immunocompromised patients are at risk to sight-threatening viral uveitis. The most important ones are herpetic necrotizing retinitis and CMV related retinitis. Such conditions require timely assessment and treatment by an ophthalmologist in order to prevent irreversible retinal damage and long-term visual impairment. This talk outlines the important risk factors for viral retinitis as well as symptoms and signs to watch out for in at-risk patients.
SESSION 5: EMERGENCIES OF THE ORBIT & NEURO-OPHTHALMIC EMERGENCIES A Patient with Diplopia When is Imaging Necessary? 15 mins Diplopia is an alarming symptom for patients and often results in presentation at the emergency department. For such patients it is important to identify those patients who require neuro-imaging. These include patients with pupil-involving CN III palsy and patients with CN VI palsy as a false localizing sign. This talk outlines the management approach to patients presenting with diplopia and the initial workup required. The Frozen Eye Cavernous Sinus Syndrome and Orbital Apex Syndrome 10 mins A painful frozen eye is an alarming presentation that should point the clinician towards a disease involving the orbital apex or the cavernous sinus.
