What is the prevalence of Benign Paroxysmal Tonic Upgaze?
How many people does Benign Paroxysmal Tonic Upgaze affect? Does it have the same prevalence in men and women? And in the different countries?
Benign Paroxysmal Tonic Upgaze (BPTU) is a rare pediatric eye movement disorder characterized by sustained upward deviation of the eyes. It typically appears in infancy or early childhood and persists throughout life. BPTU prevalence is estimated to be extremely low, affecting less than 1% of the population. Although the exact cause is unknown, it is believed to be a genetic condition. BPTU can lead to visual impairments and may require treatment, such as medication or physical therapy, to manage symptoms and improve quality of life.
Benign Paroxysmal Tonic Upgaze (BPTU) is a rare pediatric eye movement disorder characterized by abnormal upward eye positioning and sustained upward gaze. It typically manifests in early infancy or childhood and is considered a benign condition, as it does not lead to any significant neurological or developmental issues.
The prevalence of BPTU is not well-established due to its rarity and underdiagnosis. However, studies suggest that it occurs in approximately 1 in 200,000 to 1 in 500,000 children. It appears to affect both males and females equally, with no known ethnic or geographic predisposition.
BPTU episodes can be triggered or worsened by fatigue, excitement, or illness, but they typically resolve during sleep. Although the exact cause of BPTU remains unknown, it is believed to be related to a dysfunction in the brainstem or cerebellum.
While BPTU is generally considered a benign condition, it is important to consult with a pediatric neurologist or ophthalmologist for proper diagnosis and management. Although no specific treatment is available, reassurance and periodic follow-up examinations are often recommended to monitor the child's eye movements and ensure normal development.
