Optical Management Using Monovision and Yoked Prism for Acquired Strabismus and Nystagmus Secondary to a Neurodegenerative Disease

ABSTRACT

Acquired involuntary eye movement disorders, including noncomitant strabismus, nystagmus, and saccadic dyskinesia, are common ocular manifestations of many neurodegenerative diseases. These patients may experience visual symptoms, such as blurred vision, diplopia, and oscillopsia, which can significantly impact their use of vision. The goal of the management for these patients is to reduce the visual symptoms using any combination of available management strategies. This case report discusses the effective optical management using the combination of spectacle monovision correction and yoked prism to improve visual symptoms in a patient with olivopontocerebellar atrophy.

Notes

* Yoked prism: Unlike compensating prism, yoked prisms are used in both eyes in the same direction and amount for the purpose of moving both eyes.
