Double vision in older people is not something that we consider normal nor is it a typical symptom of aging, as occurs with other natural vision changes, such as presbyopia. Therefore, if we notice that an older person suddenly experiences double vision, this is generally a symptom of some underlying pathology that requires evaluation and possible treatment.
Main causes of double vision in older people
Double vision, also known as diplopia, is a symptom in which a person perceives two images of a single object when in reality there is only one. These images may appear side by side, superimposed, or in different positions, depending on the underlying cause of the diplopia. Among the most common causes of double vision in older people we find:
- Refractive eye problems: This is the case of astigmatism, myopia, hyperopia or presbyopia, especially if they are not corrected with appropriate lenses.
- Cataracts: The opacity of the lens, as a natural cause of aging, can cause double vision in older people. Cataracts are very common in older people and can be treated with surgery.
- Strabismus: This condition occurs when the eyes are not aligned correctly and point in different directions. It can be congenital or acquired and can cause double vision.
- Neurological disorders: Conditions that affect the motor nerves that control eye movements, such as stroke, multiple sclerosis, tumors, or nerve damage due to diabetes, can cause double vision.
- Myasthenia gravis: This is an autoimmune disease that weakens muscles, including those that control eye movements, which can cause double vision. Unfortunately, this disease has no cure, but there are treatments that can alleviate the signs that accompany it.
- Drug Side Effects: Some medications that affect the central nervous system can cause double vision as a side effect.
Treatments for double vision in older people
Treatment for double vision in older people will depend on the underlying cause of the condition. Some common treatments may include:
- Correction of refractive problems: If double vision is due to refractive errors such as myopia, hyperopia, astigmatism or presbyopia, the use of appropriate glasses or contact lenses can correct double vision.
- Vision rehabilitation therapy: In some cases, especially when double vision is caused by problems with the eye muscles, vision therapy exercises may be recommended to strengthen the muscles and improve eye coordination.
- Medical treatment of the underlying disease: If double vision is caused by an underlying disease such as myasthenia gravis, neuropathy, brain injuries, or other medical conditions, treatment of the underlying disease may help improve double vision.
- Surgery: In severe cases of strabismus or other eye muscle problems that do not respond to other treatments, surgery may be necessary to correct eye alignment and reduce double vision.
How to prevent the appearance of double vision and dizziness
Double vision and dizziness are two symptoms that sometimes occur together and that indicate an alteration, whether visual or not. Cases of double vision cannot always be avoided, but to prevent its appearance it is recommended:
- Perform regular vision exams.
Maintain a regular schedule of eye exams with your ophthalmologist to detect and correct any vision problems, such as refractive errors, cataracts, glaucoma or other eye conditions. - Maintain a safe environment
Avoid situations that may increase the risk of falls and injuries, such as keeping a home well lit, clear of obstacles, and using non-slip mats to prevent accidents that can cause double vision in older people. - Follow a healthy lifestyle
Having a balanced diet, exercising and avoiding tobacco and alcohol are essential measures to maintain good eye and general health. - Get adequate rest
Tiredness and fatigue can contribute to dizziness and vision problems. Make sure you get enough sleep and take regular breaks during the day if necessary. - Control diseases
Having diseases such as diabetes and hypertension under control is essential to prevent eye complications.
Double vision in older people can have important consequences that include an increased risk of falls, difficulty performing daily activities, social isolation, difficulty managing medication, and the need for specialized care 24 hours a day.
In these cases where double vision in older people affects their quality of life and safety, care in a nursing home or day center may be an option to ensure that they receive the appropriate care and supervision for their specific needs.
