Purpose
To reveal the recurrence rate of Graves ophthalmopathy (GO) presenting as diplopia in the primary position for 1 year after varied doses of intravenous methylprednisolone (IVMP) followed by oral prednisolone, with dosing based on the magnetic resonance imaging (MRI) findings.
Study design
Retrospective study.
Methods
We analyzed the medical charts of 25 patients who were diagnosed with new-onset GO and who received treatment for diplopia in the primary position at our hospital. Treatment consisted of MRI-determined varied doses of IVMP followed by oral prednisolone. If the MRI findings showed deterioration or were unchanged after 6 g of IVMP, 3 g of IVMP was added for further treatment. Simple and multiple linear regression analyses were performed to reveal the associations between the independent variables and the dependent variable, defined as recurrence.
Results
The mean patient age (± standard deviation) was 61.3 ± 11.3 years. The female to male ratio was 15:10. Twenty-one of the 25 patients received a total of 6 g of IVMP, whilst the remaining 4 patients received a total of 9 g of IVMP. In 5 patients (20%), the GO recurred within 1 year of IVMP administration. Simple and multiple linear regression analyses showed that the MRI findings after 6 g of IVMP affected recurrence (P < .05).
Conclusion
This study showed that in 20% of patients, GO recurred within 1 year of administration of varied doses of IVMP, with the dosing based on the MRI findings. Furthermore, assessment of inflammation by use of MRI after 6 g of IVMP has a potential role in predicting recurrence.
