BACKGROUND: This case report documents a case of malignant pheochromocytoma manifested as vision changes with lung metastasis and recurrence.
METHODS: A 10-year-old Han Chinese girl presented with vision changes and was eventually diagnosed with pheochromocytoma by contrast-enhanced computed tomography, urine vanillylmandelic acid. After medication for hypertension and surgery, clinical symptoms disappeared. Malignant pheochromocytoma with lung metastasis was confirmed histologically using the Pheochromocytoma of the Adrenal Gland Scaled Score scoring system and genetically with succinate dehydrogenase complex iron sulfur subunit B mutation, and 3 months later, unplanned surgery was performed because of the high risks and signs of recurrence. She is asymptomatic as of the writing of this case report. Our patient\'s case highlights the importance of considering a diagnosis of malignant pheochromocytoma, and long-term follow-up for possible recurrence.
CONCLUSIONS: Although there are well-recognized classic clinical manifestations associated with pheochromocytoma, atypical presentation, such as vision changes in children, should be considered. In addition, malignant pheochromocytoma children with a high Pheochromocytoma of the Adrenal Gland Scaled Score and succinate dehydrogenase complex iron sulfur subunit B mutation require a long-term follow-up or even unplanned surgery because of the higher risk of recurrence.

When prescribing medications, it is important to consider the ocular side effects of common systemic therapy as well as potential systemic side effects of ocular medications. Although not an exhaustive list of medications/classes of medications, this article does include many commonly used drugs and also provides information on some topical therapies commonly used by ophthalmologists. These ocular medications may result in systemic effects and/or alter patients\' management of systemic conditions.

BACKGROUND: Emergency physicians frequently evaluate patients with vision changes. The differential for this chief symptom is broad. We present a unique cause of a fixed scotoma that started while the patient was running sprints.
METHODS: The patient described a bright central scotoma that later became a dark oblique line across her central vision. This painless defect moved predictably with eye movements. Ocular ultrasonography was performed and revealed a well-demarcated hyperechoic lesion in the posterior segment of the right eye. There was no similar lesion found in her left eye. In consultation with ophthalmology, the patient\'s history and examination were consistent with valsalva retinopathy. To our knowledge, this is only the second published case of valsalva retinopathy/premacular hemorrhage identified on ocular ultrasonography in emergency medicine literature. In this article, we further expand on management and provide correlating fundoscopic images. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Emergency physicians frequently evaluate patients with visual changes. Valsalva retinopathy is a rare cause of a visual scotoma that can be diagnosed through history and ultrasound. It often resolves over weeks to months without intervention. However, it does require urgent ophthalmologic evaluation to rule out peripheral retinal tears, which may require laser retinopexy or surgical management.
