Visual impairment
When we talk about visual impairment we mean the total or partial loss of the ability of a subject to perform, in total autonomy, the simple and recurring actions of daily life that require the support and contribution provided by the visual field.
These deficits can affect:
- visual acuity: in this case the subject is not able to distinguish the details that characterize an object. Visual acuity is also called visus and is measured by the optician or ophthalmologist.
- amplitude of the field of view: in normal conditions, it has a total amplitude of about 120 in the vertical plane and 180 in the horizontal one.
Visual deficits encompass all those problems that affect both with the vision and with the visual field. However, a distinction is made between blindness and low vision if one or both eyes are involved.
Follow us in this scientific excursus to stay up to date on innovative cures and treatments brought forward by research.
Specialized doctors will enrich this in-depth study of visual impairment through interviews, statements and articles, thus providing a valuable contribution to the dissemination of topics on which they can boast years of study and research.
