Prismotherapy in intermittent exotropia. A preliminary report

Area of Science:

• Ophthalmology
• Optometry
• Vision Science

Background:

• Intermittent exotropia is a common form of strabismus.
• Suppression is often associated with intermittent exotropia.
• Effective treatment strategies for these conditions are continuously sought.

Purpose of the Study:

• To evaluate the efficacy of prism correction in treating intermittent exotropia with suppression.
• To determine the impact of prism wear compliance on treatment outcomes.

Main Methods:

• Twenty-five patients diagnosed with intermittent exotropia and suppression were enrolled.
• Prisms were prescribed to neutralize the patients' maximum deviation.
• Patients were divided into groups based on prism wear compliance.

Main Results:

• Thirteen patients did not wear prisms correctly and served as controls; none were cured.
• Of the 12 patients who wore prisms for more than half their waking hours, 8 were cured.
• This suggests a positive correlation between prism wear and successful treatment.

Conclusions:

• Prism therapy can be an effective treatment for intermittent exotropia with suppression.
• Consistent and prolonged wear of prescribed prisms is crucial for achieving a cure.
• Further research may explore optimal prism parameters and patient selection for this intervention.
