Cones are the predominant photoreceptor in the fovea and are connected to ganglion cells in a 1:1 ratio, Ganglion cells are concentrated outside of the central fovea, allowing more light to reach the central photoreceptors, Foveal photoreceptor axons form Henles layer run in an oblique fashion due to the peripheral concentration of ganglion cells, Chronically elevated blood pressure leads to arteriosclerotic changes and vascular damage, Initial changes include vasoconstriction and vasospasm, Sclerotic intimal wall thickening manifests as AV nicking and silver and copper wiring, Eventually, disruption of the blood-retinal barrier leads to hemorrhage and plasma exudation into the retina, Severe cases can cause swelling of the optic nerve, Flame-shaped hemorrhages: in nerve fiber layer, Dot-blot hemorrhages: in inner nuclear or outer plexiform layers, Hard exudates: extracellular protein and lipid deposits left in chronic edema after water component has been removed, star-shaped due to location in Henles layer, Caused by arteriosclerosis, embolism, and vasculitis, Clinical appearance: Cherry-red spot signifying redness of underlying choroid in fovea, Edema of ganglion cell layer and NFL, which are thickest in macula but absent in fovea, Ischemia of inner 2/3 of retina to Outer Nuclear Layer, Histopathology shows inner ischemic retinal atrophy (NFL, GCL, inner plexiform layer, inner nuclear layer) after occlusion of retinal circulation, Outer ischemic retinal atrophy is indicative of an occlusion of choroidal circulation, Important clue for a systemic disorder, such as carotid vascular disease (Hollenhorst plaque), cardiac valvular disease (calcific emboli), or thromboembolism (platelet-fibrin emboli), Histology: inner ischemic atrophy of retina downstream of occluded arteriole, Structural changes in central retinal artery and lamina cribrosa central retinal vein compression turbulent flow thrombosis, Usually occur in setting of arteriosclerosis, hypertension, diabetes, glaucoma, Papillophlebitis: clinical features of CRVO, no history of vascular disease, patients under age 50, retinal vein occlusion due to inflammation of retinal vessels at the optic disc, Retinal hemorrhages in all four quadrants, Nonperfused CRVO: >10 disc areas show nonperfusion on FA, extensive retinal edema & hemorrhage, marked venous dilation, cotton-wool spots, Histology: hemorrhage, hemosiderosis, disorganized retinal architecture, cystic spaces with blood and proteinaceous exudate, nodular hyperplasia of RPE, gliosis, Microaneurysms and neovascularization follows ischemic CRVO, Arteriovenous crossing causes occlusion of branch retinal vein, Artery & vein share common adventitial sheath; arteriosclerosis leads to compression of venule, More common in arteriosclerosis and hypertension, Clinical findings: retinal hemorrhages, cotton-wool spots, Neovascularization unlikely unless >5 disc diameters of ischemia, If permanent vision loss: CME, retinal nonperfusion, pigmentary changes, macular edema with hard exudate, subretinal fibrosis, epiretinal membrane, Histology: similar to CRVO but localized to distribution of vein, Microaneurysms and dilated collaterals may be present, Thickened retinal capillary basement membrane, Fusiform or saccular outpouchings of retinal capillaries, Best seen histologically with PAS-stained trypsin digest preparation, Clinical findings and late histologic changes: hard exudates, cotton-wool spots, dot-blot & flame hemorrhages, neovascularization, Hard exudates: eosinophilic-staining extracellular protein and lipid deposits left in chronic edema after water component has been removed, Histologically are distinctly-bordered eosinophilic spaces, Cotton-wool spot: focal areas of ischemia in Ganglion Cell Layer and Nerve Fiber Layer, Cytoid bodies are the histopathologic hallmark of cotton-wool spots, Cytoid body- eosinophilic accumulation of ganglion cell axoplasmic material that develops during an ischemic event of the NFL, Leaves atrophic retina after they resolve, Categorized as proliferative if neovascularization in the eye present or non-proliferative if neovascularization is absent, Proliferative diabetic retinopathy is further categorized by the location of neovascularization: neovascularization of the disc (NVD) and neovascularization elsewhere (NVE), Chronic retinal ischemia results in the release of vascular endothelial growth factor (VEGF), which stimulates the growth of new, incompetent blood vessels and increases vascular permeability, Boat-shaped hemorrhage: blood in potential space between posterior hyaloid and internal limiting membrane.
