What does the term "diplopia" mean?

The term "diplopia" is derived from the Greek word "diplous," meaning double. It specifically refers to the condition of seeing two images of a single object, which is commonly known as double vision. This can occur in both horizontal and vertical orientations, and it may affect one or both eyes.

Understanding diplopia is crucial for eye health professionals since it can be indicative of underlying health issues, such as strabismus, cranial nerve palsies, or other neurological conditions. Recognizing diplopia as a distinct visual disturbance helps in planning appropriate diagnosis and treatment strategies for patients experiencing this symptom.
