Cause: Posterior Vitreous Detachment
With the progression of age, the vitreous gel within our eyes tends to decrease in size. This shrinkage leads to the gel detaching from the retina located at the back of the eye. The retina contains tiny blood vessels, and the pulling action of the gel can result in the occurrence of small tears or holes. As a consequence, a fluid forms in the pocket that develops between the gel and the retina.
Cause: Blocked Blood Vessels
Blockage of the blood vessels that supply the retina can be attributed to certain eye conditions, leading to the leakage of blood into the vitreous gel. This blockage can occur due to narrow vessels or the presence of a small clot that has migrated into the eye from another part of the body. Additionally, atherosclerosis, a prevalent condition characterized by the accumulation of fatty deposits on artery walls, can contribute to this issue if tiny particles break free and travel to the eye.
