This exhibit displays the sagittal view of the eye with a progression of an infection. The bacteria travels up the carotid artery and into the arteries of the eye. The infection then invades the vasculature within the choroid layer where it inflames and spreads to the retinal layer. Antibiotics are administered through the choroid layer of the eye to eliminate the infection, but the inflammation persists causing damage to the peripheral retina. This damage from the infection and inflammation results in peripheral vision loss, but the central retina is spared. Further complication occurs when portions of the retina detach from the underlying choroid layer (retinal detachment).
