The eye is a sensitive organ. As your blood vessels grow abnormally, it can cause you a few other complications:
Vitreous haemorrhage. When the weak blood vessels leak into the jelly-like substance which is situated in the centre of the eye, there is a risk of vitreous hemorrhage. This disease will make the vision hindrance worse and in worse cases, if the bleeding is severe, it can completely block your eye vision.

Retinal detachment: Retinal detachment is an eye disorder in which the retina is pulled away from the eye. If the blood vessel damages the tissue leaving a scar, it can detach the retina.

Glaucoma: New blood vessels are formed in the front of the eye and disturb the fluid flow out of the eye. This creates pressure on the eye that can harm the optic nerve — a nerve that conveys image signals from the eye to the brain.
