Today we will talk about what is possibly the most common disease of the visual system: blepharitis. Avispadillo anyone who has read my previous articles that already tell it me, that I have used this argument twice: to talk about the shortcomings of graduation and dry eye. To say that justify: Defects graduation I usually do not consider cases of blepharitis diseases Many (possibly most) do not give symptoms, so do not go to the doctor (you can underestimate the incidendia). It's different talk about the disease most commonly hiv test seen in the consultations the ophthalmologist, the disease that most people have Blepharitis is a cause of dry eye. So when we have patients with dry eyes also we put those with blepharitis.
In this article on uveitis put a list of Latin and Greek roots of the parts of the eye, and adding the "-itis" suffix were getting inflammation of that structure. Thus, "eyelids" blepharospasm was said therefore Blepharitis is inflammation of the eyelids. But although this is the etymological definition, do not use the term for any inflammation of the eyelid. Thus, inflammation of the skin would cause allergic dermatitis and allergic (and painful) acute infection of a gland would be a stye (discussed in the next article)
Actually, when we speak of blepharitis we refer specifically to the marginal blepharitis, ie, inflammation of the free edge of the eyelid (where the eyelashes are roughly). It may be acute, chronic, or chronic outbreaks of sharpening, but what characterizes this disease is occurs in both eyes, and both eyelids of each eye. Although it is asymmetric (more in one eye than the other) and the patient relates symptoms only in one eye, the eye examination we see inflammation in both. In many cases no symptoms, or only gives symptoms at times. Inflammation is not as bulky as a stye, although related problems. The diagnosis of blepharitis, although I suspect from the symptoms is performed with the slit lamp, because you have to see the edge of the eyelid with several increases to find the signs of the disease. [It is true that some particularly intense blepharitis we see them as we go directly to the patient in the consultation, but what I mean is that it is a diffuse inflammation whose findings are preferably evidenced by examining the eyelid margin with several increases]
Therefore, in practice mean by edge blepharitis inflammation of the eyelids, where two related factors are found: altered secretion of the glands, and an infectious component. Blepharitis has secondarily a significant effect on the ocular surface.
Let's forget about some structures that are in the thick of the eyelid, hiv test and we're going to concentrate on the edge, roughly where the tabs are. In looking farther than the eye as close, we are. The lash line: They're in 2 or 3 rows, are quite thick and long hair, and are easily seen without using a microscope. The tabs are oriented outward, so that usually do not rub the eye surface. Still on the outside edge, there are small sebaceous glands. They can lead to the same eyelash follicle or lead to side. Like the rest of the skin's hiv test sebaceous glands, produce hiv test an oily secretion that serves to "moisturize" the area, and the tab. There are also some glands whose secretion is not fat but aqueous, but for blepharitis these glands are less important. [Both glands have names: Zeiss and Moll, respectively, but neither are very important terms] Then there is a separation zone where the skin is becoming mucosa (more delicate epithelium without keratin, and more needs moisture) . Already in the back of the eyelid margin, very close to the eye, there are special glands, which are perhaps the major players today: the meibomian glands. Sebaceous glands are as I have explained before, but have certain peculiarities. They are much larger. The body of the gland extends quite in thickness eyelid fat secretion, rather than tabs, is for the tears. Does tear?. Yes: in the tear film, but is mostly water, there are other components. And the fat component is critical to not evaporate too quickly (in Article hiv test dry eye were talking about it). It is because the principal hiv test was responsible for the fat part of the tear film.
Going over the edge of the eyelid is divided into anterior, where are the eyelashes and a small accompanying glands, and the trailing edge, where they are
