Loss of vision in right eye after bypass surgery

[Ga3]

My dad recently went through bypass surgery on Jan 29th 2017. He suddenly lost his vision on his right eye yesterday.Doctors have diagnosed it to be CRAO and they told that the vision loss is irrreveraible. They have not a prescribed any medicines or treatment. Is there any other procedure or medicines that can be tried? How do we safeguard the healthy eye? Any information would be a great help. He is totally shattered and any positive suggestions could cheer him.

Thank you

There are some experimental procedures but you would have to have almost immediate access to a tertiary ophthalmic referral center. The retina has a high metabolic need for blood flow and starts to die quickly after blood flow is interrupted in a major artery. The most common cause is a blood or cholesterol clot (emboli) to the eye. A search needs to be done by cardiologists looking for where the clot might have originated. Common sources are the heart or the carotid arteries.

It is extremely important that whatever ophthalmologist is treating him do a complete exam on the remaining good eye to be sure it does not have glaucoma, macular degeneration, etc.  Also important your father protect the good eye from injury and that he lead an ultra healthy lifestyle. No nicotine, control blood pressure, blood lipids, watch weight and diet, some exercise, test for diabetes.
