Which type of glaucoma is symptomless?

Open-angle glaucoma is often referred to as a symptomless or "silent" condition, and this is primarily due to its gradual progression. In the case of open-angle glaucoma, there is a slow increase in intraocular pressure, and the changes to the optic nerve and peripheral vision occur so subtly that individuals may not notice any symptoms until significant damage has already occurred. This makes regular eye examinations crucial for early detection and management, as many patients may be unaware that they are affected until their vision has been compromised.

In contrast, other forms of glaucoma, such as closed-angle glaucoma, can present with acute symptoms like severe eye pain, headache, blurred vision, and nausea, typically requiring immediate medical attention. Secondary glaucoma and congenital glaucoma may also show symptoms or visual changes, making it essential to understand the distinctions between these types when considering the silent nature of open-angle glaucoma. Thus, recognizing that open-angle glaucoma often develops without noticeable symptoms underscores the importance of proactive eye care and screening.
