Bilateral internuclear ophthalmoplegia developing as a manifestation of dengue fever and treatment by modified Nishida procedure: A case report and review of the literature

Typical causes of internuclear ophthalmoplegia (INO) include demyelinating conditions, with inflammation, infection, and trauma being less common causes. Diplopia associated with INO severely impacts the patient's quality of life. Orthoptic treatment usually fails; therefore, appropriate surgical treatment should be considered. We report the unique case of a 25-year man with bilateral INO developing as a manifestation of dengue fever-related encephalitis and its successful treatment by modified Nishida procedure.
