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.

Prevalence of Benign Paroxysmal Tonic Upgaze: how many people are affected worldwide, differences by sex and region, with sources.
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.
