There is an increase in the back-pressure inside the veins. Retinal vein occlusions are caused by congestion of blood flowing out of the eye through the retinal veins. The damage can be relatively mild or quite severe, depending on the extent to which the blood flow has been disrupted. Retinal artery obstructions are like a stroke in the eye. This arterial occlusion can decrease the oxygen supply to the area of the retina nourished by the affected artery, causing permanent visual loss. A tiny blood clot or small cholesterol plaque in the blood stream may be sufficient to cause the blockage of blood flow through the artery. Retinal arterial occlusionsĪ retinal artery occlusion occurs when the central retinal artery or one of the arteries that branch off of it becomes blocked. When detached, the retina cannot compose a clear picture and vision becomes blurred and dim. This allows fluid to seep underneath the retina so that the retina becomes detached – rather like wallpaper peeling off a damp wall. Retinal detachments often develop in eyes with weakened retinas that have a retinal hole or tear. If you experience any of these symptoms you cannot know if it is a vitreous condition or a retinal detachment, therefore, you should call your eye care physician as soon as possible. Sometimes a retinal tear gives no warning at all. Flashes and floaters may be associated with a retinal detachment. They may be associated with new floaters and even with partial loss of the visual field. A similar sensation may happen if you hit or rub an eye and see “stars.” Flashes can appear once or several times. When the vitreous fluid (gel) inside the eye moves, the vitreous membrane may pull on the retina, causing a flashing sensation, although in fact there is no such light inside the eye. Collectively, they are called juvenile macular degeneration. There are several hereditary forms of macular degeneration, which affect children or teen agers. Macular degeneration occurs most often in people over 60 years old, in which case it is called age related macular degeneration (ARMD). If the macula becomes damaged, many daily activities such as driving and reading become increasingly difficult. Age-related macular degenerationĭetailed central vision is processed by the macula. Abnormal vessel growth and the development of scar tissue may cause serious problems such as retinal detachments or glaucoma. These delicate vessels bleed and leak into the retina and vitreous, causing blind spots and, later on, severe visual loss. Fragile new vessels grow in an attempt to maintain adequate oxygen levels within the retina. Poor circulation causes the retina to become oxygen-deprived (ischemic). There may be small, dot-like hemorrhages, and when the disease progresses, the swollen retina causes decreased vision. In the earliest phases, the arteries in the retina become weakened and leak.
