Guide to prevent the AMD
Age-related macular degeneration (AMD) is a condition that can severely impair your central vision.
What is it?
Age-related macular degeneration (AMD) is a disease affecting the eye that affects the central area of the retina called the MACULA resulting in decreased vision. AMD is a chronic degenerative disease that little by little, can lead to severe and irreversible loss of vision
How is it manifested?
AMD generally manifests initially in a form called “dry,” and in some cases can evolve into a more severe form, called “wet,” with the development of abnormal vascular formations also causing hemorrhages fatally impairing vision and quickly exacerbating the condition. In the former case, lesions appear on the macula, called “drusen,” whose presence is often not accompanied, at least initially, by any symptoms. DMLE is an acquired degeneration, the changes caused on the macula lead to a distortion a reduction in visual acuity, more or less severe, distinct central vision and colors of image details (e.g., reading, driving, watching TV) . In the presence of this pathology, the peripheral parts of the retina, which are responsible for side vision, appear preserved.
How is it diagnosed?
It is important to have periodic eye examinations after the age of 50 to examine the status of the retina to keep any pathology under control. THE AMSLER TEST has the function of examining the state of the retina and for the early detection of affections affecting the center of the retina, the macula and the surrounding area, that is, the point where visual acuity is at its maximum.
Let's be clear
Here is some useful information to learn more about how vision works and the new Offhealth solution for treating MSDs.
The eye or eyeball is the external part of the organ of sight. Housed in the orbital cavity, it is protected by the ocular adnexa complex (eyelids but also eyelashes and tears). The function of the eye is designed for light rays penetrating into it to focus on the retina; at the retinal level, light stimuli are transformed into nerve impulses and transmitted via the optic nerve and optic pathways to the visual area of the brain, which interprets them and enables the understanding of image and colour information received by the eye to achieve visual perception of the outside world.
The retina is the nerve layer of the eye and extends across the entire inner surface of the eyeball, stretching from the entry point of the optic nerve to the pupillary margin of the iris. Consisting of a neuronal organisation, it is made up of a pigmented epithelium overlaid with a layer of photoreceptors known as cones and rods, highly specialised cells capable of transforming light energy into electrical impulses that are transmitted to the visual areas of the brain and encoded into images. On visual (ophthalmoscopic) examination, the retina is orange-red in colour with visible retinal vessels converging towards the papilla of the optic nerve, a slightly lighter area. Slightly laterally, an area about 2 mm in diameter is visible, darker in colour, with a small depressed central area. These are respectively the macula and the fovea, the areas of maximum visual acuity being dense with photoreceptors (cones and rods).
