Abstract |
PURPOSE We report a case of convergence spasm that occurred after head trauma. CASE SUMMARY: A 18-year-old female presented with intermittent diplopia and decreased vision shortly after head trauma. Her past medical history was non-specific, except myopia in the left eye. On the initial examination, her uncorrected visual acuity and was variable (0.1~1.2 in the right eye, 0.05~0.1 in the left), but the corrected visual acuity was 1.2 in both eyes. Manifested refraction was also variable (-0.50~-5.50 diopters (D) in the right eye, -4.50~-6.50D in the left eye). Cycloplegic refraction was -0.50D in the right eye, and -4.50D in the left eye. The patient showed a variable esotropia (4~16 prism diopters (PD) at distance, 4~30PD at near). There was no limitation on abduction. There was no abnormality in the brain MRI. Five months after the initial visit, diplopia and blurred vision persisted. |
