Progressive supranuclear palsy (PSP) is a neurological disorder that can cause a variety of eye problems. These eye problems are often due to the degeneration of certain brain cells that control eye movement and can include:
-
Difficulty moving the eyes: Individuals with PSP may experience difficulty moving their eyes, particularly up and down or side to side. This can make it difficult to read, drive, and perform other tasks that require precise eye movements.
-
Double vision: Double vision or diplopia is a common symptom of PSP and can make it difficult to perform daily tasks such as reading, watching TV, and driving.
-
Blurred vision: PSP can cause blurred vision or difficulty focusing, making it difficult to read or see things clearly.
-
Eyelid problems: Individuals with PSP may experience eyelid problems such as involuntary closure of the eyelids (blepharospasm) or difficulty opening the eyes (apraxia of eyelid opening).
-
Reduced blinking: Individuals with PSP may blink less frequently than normal, which can cause dry eyes and other eye problems.
There is no cure for PSP, but some treatments can help manage its symptoms. Individuals with PSP who are experiencing eye problems should speak with their healthcare provider. An ophthalmologist or neuro-ophthalmologist may also be able to provide additional evaluation and treatment recommendations.
Treatment options for PSP-related eye problems may include:
-
Eyeglasses or contact lenses: Corrective lenses can help improve visual acuity and reduce double vision.
-
Prism lenses: Prism lenses can help reduce double vision by adjusting the angle of light entering the eyes.
-
Eye muscle surgery: Surgery may be an option for individuals with PSP who are experiencing severe eye movement problems.
-
Botox injections: Botox injections can help alleviate eyelid spasms or other involuntary eyelid movements.
-
Eye drops: Lubricating eye drops can help alleviate dry eyes caused by reduced blinking.
It is important for individuals with PSP who are experiencing eye problems to work closely with their healthcare providers and eye specialists to manage symptoms and maintain their quality of life.
