Blindness can have many causes including inherited conditions, trauma or injury, or stroke. Nausea and vomiting can occur with infections or inflammation of the digestive tract as well as with food poisoning. These symptoms could occur at the same time and may not be related. Seek immediate medical care for the sudden onset of blindness or vision difficulty. Discuss any concerning symptoms with your doctor.
While the list below can be considered as a guide to educate yourself about these conditions, this is not a substitute for a diagnosis from a health care provider. There are many other medical conditions that also can be associated with your symptoms and signs. Here are a number of those from MedicineNet:
-
Food Poisoning
Food poisoning is common but can also be life-threatening. Food poisoning symptoms include stomach cramps, diarrhea, and vomiting. Read about different types of food poisoning, treatment, and tips for prevention.
-
Stroke Symptoms and Treatment
A stroke is an interruption of the blood supply to part of the brain caused by either a blood clot (ischemic) or bleeding (hemorrhagic). Symptoms of a stroke may include weakness, numbness, double vision or vision loss, confusion, vertigo, difficulty speaking, or understanding speech. A physical exam, imaging tests, neurological exam, and blood tests may be used to diagnose a stroke. Treatment may include administration of clot-busting drugs, supportive care, and in some instances, neurosurgery. The risk of stroke can be reduced by controlling high blood pressure, high cholesterol, diabetes, and stopping smoking.
-
Sickle Cell
Sickle cell anemia (sickle cell disease), a blood disease which shortens life expectancy, is caused by an inherited abnormal hemoglobin. Symptoms of sickle cell anemia may include bacterial infections, painful swelling of the hands and feet, fever, leg ulcers, fatigue, anemia, eye damage, and lung and heart injury. Treatment for sickle cell anemia aims to manage and prevent the worst manifestations of the disease and focuses on therapies that block red blood cells from stacking together, which can lead to tissue and organ damage and pain.

Diabetic Ketoacidosis
Diabetic ketoacidosis (DKA) is a complication of type 1 diabetes that is life threatening. If a person thinks they may have diabetic ketoacidosis they should seek medical care immediately. Diabetic ketoacidosis happens when a person's insulin levels in the blood become dangerously low. Symptoms of diabetic ketoacidosis include dehydration, abdominal pain, confusion, and nausea and vomiting. Diabetic ketoacidosis needs medical treatment. It cannot be treated at home.
