Hemorrhage Preretinal

Hemorrhages limited to subretinal fluid are called preretinal. They come in two types - central and paracentral. Central - localized in the center of the fundus, or at the junction of the internal border plate and the choroid. Paracentral - located along the edge of the retina, closer to the vitreous body. In addition to the shape, hemorrhages also differ in size from several millimeters to several centimeters. Large bruises can occur with severe mechanical eye injuries. The vitreous body is an excellent nutrient medium for inflammation of the choroid and the development of purulent processes, since it contains a certain amount of fluid, blood, organs of immunocompetent cells, as well as a large content of substances that are needed for metabolic processes. This structure of the structures contributes to the spread of infection throughout the eye.

There are intravitreous and subtemporovitreous hemorrhages. As the name suggests, they are located within the sclera or extend from it in any direction. This does not mean that they are not present in other parts of the eyeball. Subtemporovitreous are found there quite often. Through a narrow area under the conjunctiva, blood, exudate, and infection enter the anterior chambers from the vascular system. They have different configurations, shapes, and sizes with anterior localization. When viewed from the rear, they are not only very widespread, but also large in size.
