	'''Sickle cell retinopathy''' is a complication of [[sickle cell disease]], a group of disorders that affect [[hemoglobin]], the molecule in [[red blood cells]] that delivers [[oxygen]] to cells throughout the body. Sickle cell retinopathy primarily affects the [[retina]], the layer of tissue at the back of the inner eye that converts light images to nerve signals and sends them to the brain.

	==Pathophysiology==		==Pathophysiology==
	Sickle cell retinopathy is caused by the abnormal, sickle-shaped red blood cells that block blood vessels in the retina. This blockage can lead to a lack of oxygen, or [[ischemia]], in the retina, which can cause damage and lead to vision loss. The retina can also become damaged due to [[neovascularization]], the growth of new, abnormal blood vessels in response to the ischemia.

	Symptoms of sickle cell retinopathy can vary widely, from no symptoms at all to severe vision loss. Common symptoms can include [[floaters]], [[blurred vision]], and [[visual field loss]].
