What's Behind That Double Vision? Understanding Diplopia
Published: Jan 10, 2024
Double vision, or diplopia, can be more than just a minor annoyance. Understanding its causes and symptoms can help in seeking the right treatment.
What is Diplopia?
Diplopia refers to seeing two images of a single object, which can be due to problems with the muscles that move the eyes. It’s important to identify whether it’s binocular (both eyes open) or monocular (one eye open). Binocular diplopia indicates a misalignment issue, while monocular could suggest local eye disease. Patients often choose to close one eye to alleviate the symptom.
Types of Diplopia
Vertical diplopia involves seeing images stacked on top of each other and can arise from issues with specific eye muscles. Horizontal diplopia causes side-by-side images and often relates to problems with the medial or lateral eye muscles. Torsional diplopia, although less common, involves images rotating relative to each other.
Understanding the Causes
Diplopia can result from a variety of causes, including nerve palsies, thyroid problems, or even neurological conditions like myasthenia gravis. Each cause requires a different approach to diagnosis and treatment, underscoring the importance of a thorough medical evaluation.
