A Case Report of Inferior Rectus Abscess
DOI: https://doi.org/10.21980/J8J35GNon-contrast computed tomography (CT) imaging of the head in coronal, sagittal, and axial planes revealed a distinct 1.7 x 2.2 x 1.4 cm peripherally enhancing fluid collection within the left inferior orbit, involving the inferior rectus (yellow circle). This lesion resulted in restricted extraocular motility due to structural compression of the left globe. Laboratory results showed a mildly elevated white blood cell count of 11.5/mm3 and otherwise normal results including C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR).
A Case of Painful Visual Loss – Managing Orbital Compartment Syndrome in the Emergency Department
DOI: https://doi.org/10.21980/J8N35DBy the end of this simulation, learners will be able to: 1) demonstrate the major components and a systematic approach to the emergency ophthalmologic examination, 2) develop a differential diagnosis of sight-threatening etiologies that could cause eye pain or vision loss, 3) demonstrate proficiency in performing potentially vision-saving procedures within the scope of EM practice.
The Clue is in the Eyes. A Case Report of Internuclear Ophthalmoplegia
DOI: https://doi.org/10.21980/J8DP9MThere was no appreciable esotropia or exotropia noted on straight gaze (yellow arrows). On extraocular muscle examination, patient was noted to have a complete left medial rectus palsy consistent with a left internuclear ophthalmoplegia (red arrow). This was evidence by both eyes easily gazing left (green arrows); however, with rightward gaze, her left eye failed to gaze past midline (red arrow).
Sonographic Retrobulbar Spot Sign in Diagnosis of Central Retinal Artery Occlusion: A Case Report
DOI: https://doi.org/10.21980/J8735PThe bedside ocular ultrasound (B-scan) was significant for small, hyperechoic signal (white arrow) in the distal aspect of the optic nerve, concerning for embolus in the central retinal artery. Subsequent direct fundoscopic exam was significant for a pale macula with cherry red spot (black arrow), consistent with central retinal artery occlusion (CRAO).
A Case Report of Invasive Mucormycosis in a COVID-19 Positive and Newly-Diagnosed Diabetic Patient
DOI: https://doi.org/10.21980/J81M1GOn physical exam, when the patient was asked to try and look to her right, the right eye failed to move laterally/abduct (blue arrow). Additionally, when asked to look straight ahead, the eye was slightly adducted (red arrow). There was a lack of motion of the right eye in abduction when the patient was asked to look to her right (yellow arrow).
Case Report of Herpes Zoster Ophthalmicus with Concurrent Parotitis
DOI: https://doi.org/10.21980/J8R93NThe presence of soft tissue stranding about the parotid gland suggested an underlying inflammatory or infectious process of the parotid gland. Cellulitis was considered as a possible diagnosis as well, given the presence of soft tissue stranding in the dermis that is adjacent to the parotid gland. Fortunately, no enhancement was seen in local muscles, fascia, or bones to suggest a myositis, fasciitis, or osteomyelitis. By using the anatomy of the patient and understanding the changes that occur on CT when inflammation is present, the appropriate depth and location of infection can be made, allowing for appropriate treatment regimens.
Use of An Ophthalmology Tutorial to Improve Resident Comfort with the Emergency Eye Exam
DOI: https://doi.org/10.21980/J86H0MBy the end of this small group didactic, learners will be able to: 1) demonstrate ability to focus on the various components of the slit lamp exam 2) demonstrate understanding of a systematic approach to the eye exam 3) demonstrate appropriate use of the Diaton, iCare, and Tonopen tonometers.
Vitreous Hemorrhage Case Report
DOI: https://doi.org/10.21980/J88D3BPoint of care ultrasound (POCUS) revealed hyperechoic material in the vitreous consistent with a vitreous hemorrhage. On the ultrasound images, there is visible hyperechoic debris seen floating in the vitreous as the patient moves his eye. Since the vitreous is typically anechoic (black) in color on ultrasound, turning up the gain on the ultrasound machine makes these findings easier to see and often highlights abnormalities, such as this hemorrhage (see annotated still).
Case Report of a Man with Right Eye Pain and Double Vision
DOI: https://doi.org/10.21980/J8KW7GABSTRACT: A 39-year-old previously healthy male presented with three days of right eye pressure and one day of binocular diplopia. He denied history of trauma, headache, or other neurological complaints. He had normal visual acuity, normal intraocular pressure, intact convergence, and no afferent pupillary defect. His neurologic examination was non-focal except for an inability to adduct the right eye past midline
Build Your Own Eye: A Method for Teaching Ocular Anatomy and Pathophysiology
DOI: https://doi.org/10.21980/J8GS8WBy the end of this session the participant will be able to: 1) Describe basic anatomy of the eye, 2) Build a basic model of the eye, 3) Identify which diseases are associated with which parts of the eye, 4) Identify the pathophysiology behind diseases of the eye, 5) Name correct treatment for each disease.
