Vossius Ring

Vossius ring (also known as vossius ring cataract) is a type of cataract in which the lens of the eye becomes cloudy around the periphery, but the central part remains clear. This type of cataract was first described by the Dutch physician Gerhard Vossius in 1619, which is why it bears his name.

With fossius ring, the outer part of the lens loses its transparency and becomes white or gray. The central zone of the lens remains clear, forming something like a “window” through which the person can still see. Over time, the opacification spreads toward the center, eventually affecting the entire area of ​​the lens.

This type of cataract is more common in older people. The reasons for its occurrence are the same as for other forms of cataracts - aging, trauma, inflammation, diabetes, and taking certain medications. Diagnosis is carried out using ophthalmoscopy and other examination methods. Treatment in most cases consists of surgically replacing the clouded lens with an artificial one.

Vossius ring is an eye condition in which the iris has one or more ring-like areas due to altered areas of the proteins. Phosphidism is a disease whose symptoms are dry eyes and redness of the mucous membrane of the eyes. This condition is caused by excess loss of tear fluid
