Sudden Dizziness and Blurred Vision: Common Causes and What You Should Know

Experiencing sudden dizziness and blurred vision can be alarming. These symptoms can occur independently or together, and may be caused by a variety of underlying conditions. While some causes are relatively minor and temporary, others may require immediate medical attention. Understanding the possible reasons behind these symptoms can help individuals make informed decisions about seeking care.

1. Hypertension (High Blood Pressure)

One of the most common causes of sudden dizziness and visual disturbances is high blood pressure. When blood pressure spikes, it can lead to a feeling of lightheadedness or blurred vision. If both eyes are affected, it may indicate a systemic issue rather than a localized eye problem. Conditions such as reduced blood flow, a sudden increase in blood pressure, transient hyperglycemia, or even a minor brain bleed could be responsible. It's important to monitor your blood pressure regularly and consult a healthcare provider if you experience frequent or severe episodes.

2. Glaucoma

Understanding Glaucoma-Related Symptoms

When dizziness is accompanied by blurred vision in one eye, glaucoma becomes a more likely cause. This condition is particularly common in older adults. Sudden vision changes followed by dizziness, headaches, and even nausea or vomiting are classic signs of acute angle-closure glaucoma. As people age, the drainage angle in the eye can narrow or close, preventing proper fluid drainage and causing a rapid increase in intraocular pressure. In rare cases, symptoms may also be linked to iritis or refractive errors.

It's highly recommended to visit an eye specialist for a comprehensive evaluation if you experience these symptoms. Standard diagnostic procedures include a refraction test, fundus photography, and intraocular pressure measurement. These tests are essential for identifying the root cause and determining the appropriate treatment plan.
