Stress-Induced Oculogyric Crisis in Septo-Optic Dysplasia: Case Report.
INTRODUCTION: Oculogyric crisis (OGC) is a dystonic movement disorder of varying durations that manifests as bilateral paroxysmal upward eye deviation accompanied by involuntary blinking, tongue protrusion, and autonomic symptoms. Separately, septo-optic dysplasia (SOD) is a congenital disorder involving hypoplasia of the optic nerve as well as hypothalamic and pituitary abnormalities. In the presented case, we report a case of OGC in the setting of SOD with proposed pathogenesis.
CASE PRESENTATION: A 27-year-old female presented with a history of SOD (optic nerve hypoplasia and hypopituitarism) with acute, recurrent, painless, bilateral, intermittent, simultaneous tonic conjugate upward eye deviation (i.e., OGC) and dystonic body posturing. She experienced her first episode upon meeting her biological sister for the first time at a loud, crowded public restaurant with continued episodes of OGC increasing in frequency and duration over the subsequent months. She later responded well to treatment with carbidopa/levodopa.
CONCLUSION: Based on our current understanding of OGC, we hypothesize that acute stressful life events in the setting of prior hypothalamic-pituitary axis dysfunction secondary to SOD could lower the threshold for developing OGC. Although most cases of OGC are idiopathic, various etiologies including medications, stress, and hormonal imbalance have been postulated as possible pathogenic mechanisms. We describe a case of SOD with OGC, and based upon our review of the English language ophthalmic literature, we believe that our case is novel.
