Despite being a disorder that involves a small slice of the population (it is estimated that about 8% of men and 0

Emeralopia - Night Blindness

Generality Hemeralopia - also known as night blindness - is a disorder characterized by difficulty seeing at night and in low light or twilight conditions. Subjects suffering from emeralopia present a delay in visual adaptation when they pass from dark environments to very bright environments and vice versa; however, they have a normal visual capacity during daylight hours

Ocular herpes

Definition Ocular herpes is a common infection of the eye, mainly supported by the herpes simplex virus. Although a single episode of ocular herpes tends to resolve without any complication, in some cases the infection can cause scarring at the corneal level or, worse still, irreversibly compromise the sight

Conjunctival hyperemia

Generality Conjunctival hyperemia is a frequent disorder characterized by redness of one or both eyes. This condition is often an indication of inflammation , but can recognize various causes. In fact, conjunctival hyperemia can derive from various pathologies that affect the eye and ocular adnexa, such as infections, allergies, trauma, elevated intraocular pressure, penetration of foreign bodies, incorrect use of contact lenses or exposure to irritants ( eg cigarette smoke, dust, smog, ammonia and chlorine)

I.Randi Orthokeratology

Generality Orthokeratology is a particular technique used in ophthalmology for the purpose of correcting various types of visual defects.

Retinitis

Definition Retinitis is defined as any inflammation affecting the retina, whether due to infections, hereditary degenerative diseases or inflammatory (inflammatory) processes of the neighboring ocular tissues. Although numerous sub-categories exist, retinitis can be subdivided substantially into two macro-groups; according to the cause of origin, they are distinguished: Infective retinitis, induced by bacteria, viruses (in particular, by cytomegalovirus) or mycetes Retinitis pigmentosa, hereditary-degenerative disease that almost always leads to blindness Retinitis is a real threat to eyesight,

What is uveitis? Uveitis is an inflammatory process affecting the uvea , the thin vascular tunic of the eye that is interposed between the external ocular membrane (sclera and cornea) and the retina. Although the term "uveitis" expresses the sole inflammation of the uvea, very often this word is improperly used to indicate inflammatory processes affecting other ocular structures, such as for example retina, sclera and cornea

Uveitis: diagnosis, therapy and prognosis

Uveitis and eye damage Uveitis is a generic inflammation of the uveal tract, the thin vascular membrane composed of three ocular sheets (choroid, ciliary and crystalline body) that separate the cornea and sclera from the retina. Uveitis constitutes an optical eye emergency in all respects: when not treated properly, the disease can spread to other neighboring ocular structures - such as cornea, iris and retina - causing exaggerated and sometimes irreversible damage, first of all compromising the vision and blindness

In addition, solar ophthalmodynia may depend on meningitis, headache and various febrile states

Eyes and sun protection

In summer, like the skin, even the eyes need protection. Exposure to ultraviolet rays, in fact, can favor the progressive opacification of the crystalline lens , a structure that filters and projects light onto the retina. Furthermore, solar radiation is implicated in the induction or progression of photokeratitis , retinopathy and age- related macular degeneration

Conjunctivitis: more advice in case of pollen allergy

In case of pollen allergy, it is not advisable to use decongestant eye drops based on natural plant extracts, such as chamomile, mallow and cornflower. The risk, in fact, is that they aggravate the allergic reaction. Chamomile and cornflower, in fact, belong to the Asteraceae family (also called Compositae) and if conjunctivitis is triggered by their own pollens, certainly these eye drops will not guarantee relief

Ocular allergies in domestic environments

Eye allergies do not always depend on a picnic on a beautiful flowery lawn. Some of the most common allergens, in fact, are found right at home: hair of cats and dogs , dust mites and molds . Today, the houses are perfectly isolated, limiting a change of air. This makes them, in a paradoxical way, less healthy, since the ideal conditions are created for allergens to concentrate
