1 Coexisting Thyroid Eye Disease and Myasthenia GravisA case of coexisting thyroid orbitopathy and myasthenia gravis. External photographs of the eyes and eyelids, as well as images from an MRI of the orbits, are included. Figure 1 : External photograph of eyes showing right lid retraction and left upper lid ptosis. Figure 2 : External photograph of ...Devin D. Mackay, MD; Valérie Biousse, MD
2 Bilateral Lens Subluxation in Marfan SyndromeThis is a case of known Marfan syndrome with bilateral progressive visual loss. The ocular examination showed bilateral lens dislocation. Figure 1a: Typical superonasal lens subluxation in both eyes Figure 1b: The arrows show the inferior edges of the lenses Figure 2: Optical section of the lenses u...Rabih Hage, MD; Valérie Biousse, MD
3 Cotton Wool Spots in Giant Cell ArteritisThis is a case of cotton wool spots in a patient with temporal artery-biopsy proven temporal arteritis.; ; A 66-year-old woman presents with isolated painless vision loss related to a left optic neuropathy in her left eye. She denies systemic symptoms to suggest giant cell arteritis.; Her examinatio...Rahul A. Sharma, MD, MPH; Valérie Biousse, MD
4 Artifact from Incomplete Orbital Fat Suppression on Magnetic Resonance ImagingOrbital fat has short relaxation times that results in a hyperintense appearance on T1-weighted magnetic resonance imaging (MRI). Fat suppressed T1 MRI sequences are needed to remove the fat signal and better visualize the orbital anatomy, including the optic nerve. Contrast can be used with fat sup...Matthew Boyko, MD; Valérie Biousse, MD
5 Clinical Features of NeuroretinitisA 13-year-old girl was seen for assessment of blurred vision and optic disc edema in her right eye. Her examination showed: best-corrected visual acuity of hand motion OD and 20/25 OS; pupils: no relative afferent pupil defect; color vision: 0/14 plates OD and 14/14 plates OS; humphrey visual fields...Rahul A. Sharma, MD, MPH; Jason H. Peragallo, MD; Valérie Biousse, MD
6 Fundus AutofluorescenceThe retinal pigment epithelium (RPE) has many important functions including phagocytosis of the photoreceptor outer segments. The metabolism of the photoreceptor outer segments leads to the formation of lipofuscin. Disease states and potentially increased oxidative damage can lead to the buildup of ...Jonathan A. Micieli, MD; Valérie Biousse, MD
7 Myelin Oligodendrocyte Glycoprotein (MOG) - Antibody Optic NeuritisThis is an illustrated guide to the clinical diagnosis of myelin oligodendrocyte glycoprotein (MOG)-antibody optic neuritis. Myelin oligodendrocyte glycoprotein (MOG) is a glycoprotein on the surface of myelin and is found exclusively in the central nervous system (CNS). MOG likely mediates a comple...Bryce Buchowicz, MD; Valérie Biousse, MD
8 Direct Carotid-Cavernous Sinus FistulaA 40-year-old man presented with decreased vision and redness in his left eye. He had a significant trauma to the left side of his face about one year ago, but did not seek medical attention. External examination showed significant proptosis of the left eye (Figure 1) and conjunctival injection and ...Jonathan A. Micieli, MD; Valérie Biousse, MD
9 Optic Nerve Head Granuloma from SarcoidosisWe present a case of optic neuropathy with optic nerve head granuloma as the presenting sign of neurosarcoidosis. Initial patient presentation was notable for a chronic cough and worsening of vision in the left eye. Subsequent imaging revealed multiple brain lesions and the presence of a subcarinal ...Nithya Shanmugam; Valerie Biousse
10 Optic Disc Edema and PseudoedemaA presentation covering how to approach optic disc edema, including clinical characteristics and the distinction of pseudoedema.Rahul A. Sharma, MD, MPH; Valérie Biousse, MD
11 Ganglion Cell Layer Analysis by Optical Coherence Tomography (OCT)A normal optical coherence tomography (OCT) of the macula is shown (Figure 1) and the various layers of the retina are labelled (Figure 2). The cell bodies of retinal ganglion cells (RGC) are located in the ganglion cell layer (GCL) of the retina and mostly synapse in the lateral geniculate nucleus ...Jonathan A.
