Effect of Visual Training on the Vertical Vergence Amplitude

Key Points

• This research aims to investigate how visual training affects vertical vergence amplitudes in patients with and without vertical heterophoria.
• Conducted visual training on three symptomatic patients with vertical heterophoria
• Measured vertical vergence amplitudes before and after training
• Compared results with subjects exhibiting normal binocularity
• Significant increase in vertical vergence amplitude observed in symptomatic patients after training
• No change in vertical vergence amplitudes in subjects with normal binocularity
