Summary
Convergence insufficiency is often undiagnosed in thyroid eye disease (TED). This study found that some patients with TED and convergence insufficiency improved with vision therapy, suggesting it should be considered in diagnosis.
Area of Science:
- Ophthalmology
- Endocrinology
Background:
- Thyroid eye disease (TED) can cause various ophthalmic symptoms.
- The prevalence and impact of convergence insufficiency in TED patients are not well-established.
Purpose of the Study:
- To investigate the incidence of convergence insufficiency in patients with thyroid eye disease.
- To evaluate the effectiveness of convergence exercises in treating convergence insufficiency among these patients.
Main Methods:
- Prospective evaluation of 27 consecutive patients diagnosed with thyroid eye disease.
- Assessment of symptomatic convergence insufficiency and response to vision therapy.
Main Results:
- Six patients presented with symptomatic convergence insufficiency.
- These six patients experienced varying degrees of subjective and objective improvement following convergence exercises.
- No other TED-related complaints requiring intervention were noted in these six patients.
Conclusions:
- Clinicians should consider screening for convergence insufficiency in patients with thyroid eye disease, especially those with nonspecific ophthalmic complaints.
- Vision therapy may offer benefits for convergence insufficiency in select TED patients.
