Your prognosis depends on many factors, including the location of the blockage and complications that arise. Some people have permanent vision damage, while others have vision that gradually gets better over time. Your eye care specialist is the best person to tell you exactly what you can expect in your individual situation.
Your provider may refer you to vision rehabilitation. This is a form of rehab that teaches you techniques for living with reduced vision. These may include using devices like magnifying glasses or assistive-computer technology. Your provider may also refer you to a social worker who can help you cope with lifestyle changes.
