Many different conditions may lead to loss of vision, including the most common white water, blue water, and diabetic retinopathy. Macular degeneration and inflammation of the chromosome are less common but occur somewhat frequently
Retinal detachment also causes loss of vision, often compared to the fall of the curtain on the field of vision and may precede loss of vision and the collapse of sparks or flashes of light or a sharp increase in the number of black objects in the field of vision
Blueberry is an inflammation of the middle layer of the eye that consists of the iris, choroid and ciliary body, which in many cases is due to a general disease of the body such as rheumatoid arthritis or infection. There may be redness, but the symptoms often consist primarily of weakness or blurred vision. Other diseases that may lead to vision loss are blockage of blood vessels that usually feed the retina through a blood clot
The loss of vision is generally surprising if the vessel is arterial, but the loss of vision may be surprising if the vessel is arterial but may be slower to occur if the vessel that blocked the vein is usually affected by only one eye
