In general, branch retinal vein occlusion has a good prognosis: after 1 year 50–60% of eyes have been reported to have a final visual acuity of 20/40 or better even without any treatment. With time the dramatic picture of an acute branch retinal vein occlusion becomes more subtle, hemorrhages fade so that the retina can look almost normal.
Roth's spots, also known as Litten spots or the Litten sign, [ 1] are non-specific red spots with white or pale centres, seen on the retina and although traditionally associated with infective endocarditis, can occur in a number of other conditions including hypertension, diabetes, collagen vascular disease, extreme hypoxia, leukemia and HIV ...
Retinopathy is any damage to the retina of the eyes, which may cause vision impairment.

[ 2] Age-related macular degeneration is technically included under the umbrella term retinopathy but is often discussed as a separate entity ...
Vitreous hemorrhage is the extravasation, or leakage, of blood into the areas in and around the vitreous humor of the eye. [ 1] The vitreous humor is the clear gel that fills the space between the lens and the retina of the eye. A variety of conditions can result in blood leaking into the vitreous humor, which can cause impaired vision ...
