Retinopathy

This type of condition refers to retinal vascular disease or even damage to the retina due to abnormal blood flow, any damage to the retina of the eyes causing vision impairment. Although symptoms appear very late in the disease course, they are not considered painful and include: vitreous hemorrhage, small objects drifting through the field of vision, and decreased visual acuity. 

Some of the causes include gene mutations and are usually X-linked, and the condition can be resulted from diabetes, also known as diabetic retinopathy which may cause no symptoms or vision problems but it may cause blindness eventually.

Stem cells contribute to an effective rate in the treatment of Retinopathy, and this percentage varies from person to person, depending on the severity of the disease in the eye (can be cured, cannot be cured), age, and other factors.
