Eye diseases

Age-related macular degeneration is part of the group of diseases called degenerative maculopathies (macular degenerations). Specifically, the age-related form is the most frequent, especially in women, and appears from the sixth decade of the person’s life onwards. It appears bilaterally, although not always with the same severity.

Macular pucker is a disease of the retinal surface and its interface with the vitreous humour. It is characterized by the proliferation and wrinkling of an epiretinal membrane; so it is a layer of connective tissue which grows on the surface of the retina, in particular on the macula, which is the central part of the eye where distinct, high-resolution vision has its seat.

A cataract is a clouding of the crystalline lens, i.e. the structure that allows the focus of the image. This process is physiological in most cases and usually begins after the age of 60.

Astigmatism: it is a very common condition in which the cornea has an asymmetric curvature, causing blurred and distorted vision. Hyperopia: hyperopia is a visual condition in which the visual image is focused behind the retina, due to a too small eyeball or a too weak ocular dioptric power. Myopia: a myopic (short-sighted or near-sighted) person sees near objects clearly, while those in the distance are perceived blurred, which is why he tends to screw up his eyes to look into the distance.

Keratoconus is a disease characterized by a progressive deformation of the cornea into the shape of a “cone”.

It consists in a progressive thinning of the central (and paracentral) stroma, followed by an exhaustion of the cornea.

Glaucoma includes a set of ocular alterations, such as: reduction of the visual field, increased intraocular pressure, excavation of the optic disc.

Dry eye syndrome is caused by a chronic lack of lubrication of the ocular surface, with consequent constant inflammation and irritation of the eye tissues.
Dry eye syndrome is characterized by symptoms such as persistent dryness, itchy, red eye and burning sensation, associated with continued sensation of presence of a foreign body in the eye.

By the term diabetic retinopathy we refer to an eye disease which is found in most

Role of a healthy cornea: The cornea is a transparent tissue that forms the front part of the eye. The light that hits your eye first passes through the cornea, through the pupil (the dark spot in the centre of the iris), and then form images on the retina.
