Anterior uveitis involves the front of the eye and is often more noticeable early due to redness and pain. Posterior uveitis involves the back of the eye and may not cause obvious discomfort at first, but it can have a bigger impact on vision if not treated quickly.
read more about anterior vs posterior uveitis ...Anterior uveitis affects the front part of the uvea, usually the iris and the area around it. It often causes redness, pain, light sensitivity, and blurry vision. It is the most common type of uveitis.
Posterior uveitis affects the back part of the uvea, including the retina and choroid. Symptoms can include blurry or distorted vision, floaters, and sometimes eye pain. This type is less common but can be more serious because it directly affects the retina.
Both types require prompt treatment to prevent complications. Anterior uveitis is often treated with anti-inflammatory eye drops and sometimes oral medication. Posterior uveitis usually needs stronger treatments such as oral or injected steroids and medications to address any underlying cause. Your eye doctor will choose the best approach based on the location and severity of the inflammation.
