What is treatment of diplopia if you're not wanting surgery?

Prism or patching. Most important is to establish the cause of the double vision. Once we know the cause, options for treatment are: 1). Addressing the underlying cause, 2). Prism power in the glasses lenses, 3). Covering one eye, or 4). Eye muscle surgery. This depends on how much the eyes are misaligned, whether the findings are stable or changing, and the patients preference.
