Double vision

Double vision, also known as diplopia , can be permanent or temporary. It causes significant discomfort and disorientation in those who experience it. Patients describe it as seeing two images of the same object, which may be horizontally, vertically, or skewed relative to each other. Causes are diverse, ranging from eye problems to more serious neurological disorders.

Causes of double vision

Double vision can have various causes. In the case of binocular diplopia, the cause is usually problems with the muscles that control eye movement or the nerves that innervate these muscles. It can be caused by trauma, Graves' disease, neurological conditions (such as multiple sclerosis), diabetes, strokes, or tumors. Monocular diplopia is often associated with problems within the eye itself, such as cataracts, corneal problems, or retinal detachment.

As in adults, diplopia in children can result from a variety of causes, including vision defects, eye muscle problems, head injuries, neurological conditions, and even infections. The most common cause of double vision in children is strabismus . Misalignment of the eyes causes each eye to send a different image to the brain, which can cause double vision. Head injuries , such as concussions, can also affect the nerves or eye muscles, leading to temporary or permanent diplopia.

Symptoms associated with diplopia

In addition to double vision, other symptoms may occur, such as eye pain, headache, difficulty seeing, loss of balance, and muscle weakness.

Diagnosis and treatment of diplopia in patients

Diagnosis of double vision includes a detailed ophthalmological examination, as well as neurological examinations and other specialized tests depending on the suspected cause.

Treatment may include conservative measures (such as glasses with prisms, special contact lenses), pharmacological treatment, and in some cases surgical interventions.

When to Consult a Doctor?

A visit to a doctor is recommended if, in addition to diplopia, the patient also experiences other disturbing symptoms, such as weakness, headaches, balance problems, or speech difficulties. Double vision can be a symptom of a serious health condition, so prompt diagnosis and treatment are crucial.
