I was born with optic nerve hypoplasia, being left eye dominant, my right has shrunk over 35 yrs (phthisis or atrophy). what is the latest treatment?

Phthisis: Unfortunately, phthisis is a permanent condition and there is no treatment available to give you vision back in that eye. The most important thing you can do is to protect your good eye at all times, especially when you are participating in activities which are a risk to injuring that eye.

No new treatments: Unfortunately, there are no new treatments available for phthisis bulb. The atrophied eye has become disorganized and non-functional. If the eye has become cosmetically unacceptable options can include cosmetic contact lenses or a prosthetic shell which can be custom designed to fit over the shrunken eye and to look like the other eye.
