Toxic Diseases Affecting the Pigment Epithelium and Retina
Medications or other substances that find their way into the eye may cause visual dysfunction by virtue of a toxic effect on the sensory retina, the retinal pigment epithelium (RPE),…
OPHTHALMOLOGY
Diseases Causing Exudative and Hemorrhagic Detachment of the Choroid, Retina and Retinal Pigment Epithelium
Diseases primarily involving the choroid cause loss of retinal function in the macular region principally by three mechanisms: (1) reduction of blood flow within the choriocapillaris; (2) increased permeability of…
Imaging and Electrophysiological Studies
Pathophysiologic and Histopathologic Bases for Interpretation of Fluorescein Angiography The anatomy and physiology of the choroid and retina and their relationship to the normal fluorescein angiographic findings were presented in…
Folds of the Choroid and Retina
Chorioretinal Folds Any condition causing a reduction in the area of the inner surface of the sclera (scleral thickening or scleral shrinkage) will cause the inner portion of the choroid,…
Normal Macula
Anatomic Subdivisions The retina is a delicate transparent tissue of maximal thickness (approximately 0.55 mm) at the foveal margin and minimal thickness (0.13 mm) at the umbo. Anatomically the macula…
Optical Coherence Tomography Angiography and Glaucoma
Why Use Optical Coherence Tomography Angiography for Disc Assessment in Glaucoma? Vascular dysregulation of the optic nerve head and the peripapillary retina is considered as one of the risk factors…
Optical Coherence Tomography Angiography Findings in Ocular Oncology and Radiation Retinopathy
Posterior Segment Tumors 15.2.1 Retinal Tumors Melanocytoma Melanocytoma is most frequently observed at the optic disc more often in pigmented individuals, although these lesions may sometimes involve the choroid or iris….
Optical Coherence Tomography Angiography Rounds
Case 1 A 68-year-old woman with a history of dry age-related macular degeneration (ARMD) and geographic atrophy OU presented to the office complaining of some distortion in her left eye…
Optical Coherence Tomography Angiography and Anterior Segment Vasculature
Principles of Optical Coherence Tomography Angiography for the Front of the Eye We used the commercially available spectral-domain OCT RT XR Avanti with the AngioVue software (Optovue, Inc., Fremont, CA)….
Optical Coherence Tomography Angiography and Adult-Onset Foveomacular Vitelliform Dystrophy
Introduction Adult-onset foveomacular vitelliform dystrophy (AFVD) is one of the most prevalent forms of macular degeneration.1 AFVD has been included in the heterogeneous group of pattern dystrophy, in which the…
