posterior vitreous detachment
C
Asteroid Hyaloid

floaters
Explanation: 

Detailed explanation-1: -The flashes occur as the separating gel pulls on the retina. This pulling of the retina by the gel during a PVD is what puts you at risk for a retinal tear and/or retinal detachment. That is why, when you have the symptoms of a large new floater or seeing flashes of light, you must come in for a retina exam right away.

Detailed explanation-2: -PVDs are occasionally associated with vitreous hemorrhage, retinal tear and retinal detachment. These should be ruled out during dilated fundus examination of patients with a PVD. Long term complications may include vitreo-macular traction, lamellar macular holes, full-thickness macular holes and epiretinal membranes.

Detailed explanation-3: -Vitreous hemorrhage can be caused by the pathologic mechanisms of disruption of normal retinal vessels, bleeding from diseased retinal vessels or abnormal new vessels, and extension of hemorrhage through the retina from other sources.
