76 Anatomy of the Ocular FundusA review of normal features of the ocular fundus. Fundus photography using various techniques illustrate anatomic features of the ocular fundus. - Figure 1 : A) Color fundus photograph of the left optic disc and peripapillary retina showing a normal optic disc, retinal arteries, retinal veins, and...Devin D. Mackay, MD; Valérie Biousse, MD
77 Typical Idiopathic Intracranial Hypertension: Optic Nerve Appearance and Brain MRI FindingsA 24-year old African American woman was referred for bilateral optic disc edema that was incidentally noted on a routine eye examination. She had excellent visual function and dilated examination showed bilateral optic disc edema with peripapillary wrinkles in the right eye and pseudodrusen in the ...Jonathan A. Micieli, MD; Valérie Biousse, MD
78 Colloid Cyst HydrocephalusThis is a case of colloid cyst of the third ventricle complicated by severe hydrocephalus, raised intracranial pressure and papilledema. Figure 1: Fundus photographs demonstrating bilateral optic nerve head edema Figure 2a and 2b: T1-weighted axial brain MRI without contrast: Dilation of both later...Rabih Hage, MD; Valérie Biousse, MD
79 Large Sellar and Suprasellar Mass (Pituitary Macroadenoma) With Left Third Nerve Palsy and Left Optic Tract CompressionA case of a large sellar and suprasellar pituitary macroadenoma with an associated left third nerve palsy and left optic tract compression. Images from an MRI of the brain with contrast illustrate the imaging characteristics and extent of the tumor. Figure 1 : Humphrey Visual Fields (24-2 SITA-Fast)...Devin D. Mackay, MD; Valérie Biousse, MD
80 Metastatic Ovarian Cancer to the Left Occipital Lobe With Complete Right Homonymous HemianopiaA case of metastatic ovarian cancer to the left occipital lobe with a complete right homonymous hemianopia. Humphrey visual fields as well as images from an MRI of the brain are included. Figure 1 : Humphrey visual fields showing a complete right homonymous hemianopia Figure 2 : MRI brain T1 axial...Devin D. Mackay, MD; Valérie Biousse, MD
81 Vertical Diplopia Secondary to Skew Deviation With Ocular Tilt Reaction With Multiple Posterior Fossa MetastasesThis is a case of multiple brain metastases in the posterior fossa resulting in a skew deviation. Figure 1 : Photograph of the patient demonstrating a spontaneous right head tilt. The patient's head is tilted toward his right shoulder to suppress his diplopia Figure 2 : Ocular movements : There is a...Rabih Hage, MD; Valérie Biousse, MD; Jason Peragallo, MD
82 Fourth Nerve SchwannomaThis is a case of IVth cranial nerve schwannoma, showing an enhancement in the subarachnoid space consistent with the clinical presentation. Figure 1a : T1-weighted axial brain MRI Figure 1b : T1-weighted axial brain MRI : magnification of the brainstem Figure 1c : T1-weighted axial brain MRI : cr...Rabih Hage, MD; Valérie Biousse, MD
83 Large Frontal Meningioma with Mass Effect and Increased Intracranial PressureThis is a case of frontal meningioma presenting with raised intracranial pressure and bilateral papilledema responsible for visual loss. Figure 1: Goldmann visual field of the left eye. In the right eye, there was no response to the V4e. The visual field is severely constricted in the left eye. Fig...Rabih Hage, MD; Valérie Biousse, MD
84 Ocular Fundus ExaminationReview of various techniques of ocular fundus examination, including direct ophthalmoscopy, binocular indirect ophthalmoscopy, slit lamp binocular indirect ophthalmoscopy, and fundus photography. Advantages and disadvantages of each technique are discussed.Devin D. Mackay, MD; Valérie Biousse, MD
85 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
86 Optical Coherence Tomography of the Retinal Nerve Fiber LayerA normal optical coherence tomography (OCT) of the macula is shown highlighting the position of a single retinal ganglion cell and its axon in the retinal nerve fiber layer (Figure 1). The topographical relationship of retinal ganglion cells in the retina to the visual field and position in the ante...Jonathan A. Micieli, MD; Valérie Biousse, MD
87 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. Micieli, MD; Valérie Biousse, MD
88 Normal Retinal AnatomyNormal posterior vitreous, retinal and chroroidal anatomy (pictures, fluorescein angiography and optical coherence tomography). Figure 1: Normal fundus photograph of the left eye o a : Optic disc and fovea o b : Foveal reflex in young patients o c : Macular and foveal areas share the same center o d...Rabih Hage, MD; Valérie Biousse, MD
89 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
