VITREOIAL

The vitreous humour is present within the eyeball and is composed of a transparent gel made of 99% water, and for the remaining part, by molecules of collagen and hyaluronic acid. As we age, the vitreous humour undergoes a degenerative process that alters its structure and transparency. Conditions like myopia, diabetes or surgery tend to accelerate this process. Patients may notice the appearance of dark spots and cobwebs floating in the visual field that are more evident when looking at a light colored, bright background. The onset of symptoms can be sudden or slow and progressive. In most cases, these symptoms tend to persist for a long time. When symptoms are acute, is advisable that the patient undergo a fundus examination to exclude retinal lesions.
